Application, you know the risk of SQL injection. Sql injection is caused when data is inserted into database that hasn’t been properly sanitized. For example, a simple demonstration of SQL injection would be an exploit that give a malicious person administration access to your site.</div><div class="MsoNormal"><br /></div><div class="MsoNormal">Say you have an HTML form that requires a username and password. Each of these form fields are named “user” and “pass”, respectively. On backend, the authentication mechanism checks the username and password against the database like this:</div><div class="MsoNormal"><b>SELECT * FROM usertable WHERE username = ‘$user’ AND password = ‘$pass’;</b></div><div class="MsoNormal"><br /></div><div class="MsoNormal">If form data is unsanitized but the user actually inputs proper username and password, then the SQL query works and authentication is granted. However, if someone enters a more malicious string, they can wreak havoc on your system. For example, if user entered a username of user ’OR 1=1;-- and any password then SQL will also be valid and will give the user access to the protected system. The query would actually be run is shown here:</div><div class="MsoNormal"><b>SELECT * FROM usertable WHERE username = ‘user’ OR 1=1;--random password</b></div><div class="MsoNormal"><br /></div><div class="MsoNormal">To understand the practical danger in this query, you have to understand that two dashes (--) is equivalent to the comment. Everything after he – is ignored by MySQL so it doesn’t matter if invalid password is provided. Also, because you haven’t “escaped” the single quote in the username, the single quote becomes the “end” of the value being checked against the username field. Though this is properly invalid as well, it doesn’t matter because the attack adds an OR 1=1 (which is always true) into the query. The query read, “Retrieve the record from usertable where username is ‘user’ or 1=1.” Because 1 is always equals to 1, the SQL always evaluates as true and attacker can access the protected resources or application.</div><div class="MsoNormal"><br /></div><div class="MsoNormal">To prevent against a possible SQL injection attack, the WordPress database class provides the $wpdb-&gt;prepare () method. It handles data sanitization of SQL statements to prevent against SQL injection,as show in below example. Note that instead of using %d to indicate a numerical replacement, you could use %1$d syntax to indicate, “replace this placeholder with the first replacement value in the format of a number.”</div><div class="MsoNormal"><br /></div><div class="MsoNormal"><b style="mso-bidi-font-weight: normal;">Using the prepare () method to sanitize SQL against SQL Injection attacks.</b></div><div class="code"><div class="MsoNormal">$sanitized_sql = $wpdb-&gt;prepare (“’INSERT INTO my_plugin_table SET field1 = %1$d, field2 = %2$s, field3 = %3$s’, 13, ‘Php code’, ‘Wordpress’);</div><div class="MsoNormal">$wpdb-&gt;query ($sanitized_sql);</div></div><div class="MsoNormal"><br /></div></div>https://www.phptutorialforbeginners.com/2013/06/preventing-sql-injection-php-code-for.htmlnoreply@blogger.com (Anil Gupta)0tag:blogger.com,1999:blog-2100928329644461483.post-8239529934692903581Tue, 16 Apr 2013 09:32:00 +00002013-04-16T15:05:36.820+05:30PHPget uploaded file extension phpget extension of file in phpphp get file extension from stringphp find files with extensionget extension from filename phpphp split file extensionReading extension of uploaded file in php | PHP Tutorials for Beginners<div dir="ltr" style="text-align: left;" trbidi="on"><span style="font-family: Arial, Helvetica, sans-serif;">In this tutorial of php code for beginners we will show you how to fetch or read the extension of currently uploaded file.</span><br /><span style="font-family: Arial, Helvetica, sans-serif;">There are two simple way to read the extension of file, one is by using the php string function and another is by user of fileinfo() function.

Constant is case-sensitiv and constant identifiers are always uppercase. A constant name always starts with a letter or underscore. A constant value cannot change during the execution of the script. If we have defined a constant, it can never be changed.&nbsp;</span><br /><span style="font-family: Arial, Helvetica, sans-serif;"><br /></span><b><span style="color: blue; font-family: Arial, Helvetica, sans-serif;"><u>How to define Constant</u>:-</span></b><br /><span style="font-family: Arial, Helvetica, sans-serif;">To define a constant we have to use define() function and to retrieve the value of a constant, we have to use its name. Unlike &nbsp;variables constants do not have $ sign.</span><br /><div class="code"><br /><br /><span style="color: red; font-family: Arial, Helvetica, sans-serif;">&lt;?php</span><br /><span style="color: red; font-family: Arial, Helvetica, sans-serif;"><span class="Apple-tab-span" style="white-space: pre;"> </span>define("PAGE_TITLE", "PHP Tutorials for Beginners");</span><br /><span style="color: red; font-family: Arial, Helvetica, sans-serif;"><span class="Apple-tab-span" style="white-space: pre;"> </span>define("DESC", "Php constant tutorial example");</span><br /><span style="color: red; font-family: Arial, Helvetica, sans-serif;"><br /></span><span style="color: red; font-family: Arial, Helvetica, sans-serif;"><span class="Apple-tab-span" style="white-space: pre;"> </span>echo PAGE_TITLE; <span class="Apple-tab-span" style="white-space: pre;"> </span>// Output:- PHP Tutorials for Beginners</span><br /><span style="color: red; font-family: Arial, Helvetica, sans-serif;"><span class="Apple-tab-span" style="white-space: pre;"> </span>echo DESC; <span class="Apple-tab-span" style="white-space: pre;"> </span>// Output:- Php constant tutorial example</span><br /><span style="color: red; font-family: Arial, Helvetica, sans-serif;">?&gt;</span><br /><br /></div><span style="color: blue; font-family: Arial, Helvetica, sans-serif;"><b><u>Differences between constants and variables are</u>:-</b></span><br /><span style="font-family: Arial, Helvetica, sans-serif;">There is no need to write a dollar sign ($) before a constant, where as in Variable one has to write a dollar sign.</span><br /><span style="font-family: Arial, Helvetica, sans-serif;">Constants cannot be defined by simple assignment, they may only be defined using the define() function.</span><br /><span style="font-family: Arial, Helvetica, sans-serif;">Constants may be defined and accessed anywhere without regard to variable scoping rules.</span><br /><span style="font-family: Arial, Helvetica, sans-serif;">Once the Constants have been set, may not be redefined or undefined.</span><br /><span style="font-family: Arial, Helvetica, sans-serif;"><br /></span><span style="font-family: Arial, Helvetica, sans-serif;">Hope this php tutorial is useful for you.

At this time our php allow you to use his function called header() to redirect the user appropriate location. Simple example to use redirect is in any <a href="http://phpcodeforbeginner.blogspot.com/2012/10/php-simple-login-form-php-tutorial-for.html">login form</a>. If username and password are correct then redirect user to this dashboard else redirect him again to <a href="http://phpcodeforbeginner.blogspot.com/2012/10/php-simple-login-form-php-tutorial-for.html">login form</a>.</span><br /><span style="font-family: Arial, Helvetica, sans-serif;"><br /></span><span style="color: blue; font-family: Arial, Helvetica, sans-serif;"><b>PHP Redirect Code</b></span><br /><span style="font-family: Arial, Helvetica, sans-serif;"><br /></span><br /><div class="code"><span style="color: red; font-family: Arial, Helvetica, sans-serif;">&lt;?php&nbsp;</span><br /><span style="color: red; font-family: Arial, Helvetica, sans-serif;">header("HTTP/1.1 301 Moved Permanently");&nbsp;</span><br /><span style="color: red; font-family: Arial, Helvetica, sans-serif;">header("Location: http://www.phpredirecttutorial.com");&nbsp;</span><br /><span style="color: red; font-family: Arial, Helvetica, sans-serif;">?&gt;</span></div><span style="font-family: Arial, Helvetica, sans-serif;">It is 301 permanent redirect, because we have used "header("HTTP/1.1 301 Moved Permanently")". If you want to use 302 temporary redirect simply skip this line and write below code.</span><br /><br /><div class="code"><span style="color: red; font-family: Arial, Helvetica, sans-serif;">&lt;?php&nbsp;</span><br /><span style="color: red;"><span style="font-family: Arial, Helvetica, sans-serif;">header("Location: http://www.</span><span style="font-family: Arial, Helvetica, sans-serif;">phpredirecttutorial</span><span style="font-family: Arial, Helvetica, sans-serif;">e.com");&nbsp;</span></span><br /><span style="color: red; font-family: Arial, Helvetica, sans-serif;">?&gt;</span></div><b><span style="font-family: Arial, Helvetica, sans-serif;">NOTE:-&nbsp;</span><span style="font-family: Arial, Helvetica, sans-serif;">This would result in a "302 Moved Temporarily" redirect instead of a 301 one.

But in some cases we require to pass our data to another page like <a href="http://phpcodeforbeginner.blogspot.com/2012/10/php-simple-login-form-php-tutorial-for.html">login form</a> or shopping cart websites. In this situation php session help us to transfer the data. The data is user information which is store on server for later use. This information is temporary and it will be deleted when browser is closed.</span><br /><span style="font-family: Arial, Helvetica, sans-serif;"><br /></span><span style="font-family: Arial, Helvetica, sans-serif;"><b>A Session variable is used to store the information of user. We can store any information required for user in session.</b></span><br /><span style="font-family: Arial, Helvetica, sans-serif;"><br /></span><span style="font-family: Arial, Helvetica, sans-serif;">Sessions work by creating a unique identification number for each visitor and storing variables based on this ID. This helps to prevent two users' data from getting confused with one another when visiting the same webpage.</span><br /><span style="font-family: Arial, Helvetica, sans-serif;"><br /></span><span style="font-family: Arial, Helvetica, sans-serif;"><b>Syntax of session is:-</b> $_SESSION['variable_name'].</span><br /><span style="font-family: Arial, Helvetica, sans-serif;"><br /></span><span style="color: blue; font-family: Arial, Helvetica, sans-serif;"><b><u>How to start php session</u>:-</b></span><br /><span style="font-family: Arial, Helvetica, sans-serif;"><br /></span><span style="font-family: Arial, Helvetica, sans-serif;">We can to use session&nbsp;directly&nbsp;and store the user information. First we need to start the session. To start session we have to write session_start() at the beginning of our code, before any HTML or text.</span><br /><span style="font-family: Arial, Helvetica, sans-serif;"><br /></span><span style="font-family: Arial, Helvetica, sans-serif;">Before you can begin storing user information in your PHP session, you must first start the session. When you start a session, it must be at the very beginning of your code, before any HTML or text is sent.</span><br /><span style="font-family: Arial, Helvetica, sans-serif;"><br /></span><span style="font-family: Arial, Helvetica, sans-serif;">Here is the example of how to start the session.</span><br /><br /><div class="code"><span style="color: red; font-family: Arial, Helvetica, sans-serif;">&lt;?php</span><br /><span style="color: red; font-family: Arial, Helvetica, sans-serif;"><span class="Apple-tab-span" style="white-space: pre;"> </span>session_start(); // starting our PHP session!&nbsp;</span><br /><span style="color: red; font-family: Arial, Helvetica, sans-serif;">?&gt;</span></div><span style="font-family: Arial, Helvetica, sans-serif;"><br /></span><span style="color: blue; font-family: Arial, Helvetica, sans-serif;"><b><u>Storing data in a session variable</u>:-</b></span><br /><span style="font-family: Arial, Helvetica, sans-serif;"><br /></span><span style="font-family: Arial, Helvetica, sans-serif;">When we want to store user information in session the we have to use $_SESSION. $_SESSION is an associative array.

You can find every website have contact us form. With <b>Contact us form or feedback form</b> the owner of site comes to know what&nbsp;people&nbsp;think about there site. Php contact form is very easy to create. In this tutorial of php code for beginners I will show you the step by step&nbsp;procedure&nbsp;to create your contact us form in php.<br /><br /><b>First we create a html page for our contact us form. Copy the below code and save as contact.php/ contact.html.</b><br /><br />&lt;html&gt;<br />&lt;body&gt;<br />&lt;table&gt;<br />&lt;form name="contact_form" method="post" action="php_contact_form.php"&gt;<br />&lt;tr&gt;<br />&lt;td&gt;&lt;b&gt;PHP Contact Form&lt;/b&gt;&lt;/td&gt;<br />&lt;/tr&gt;<br />&lt;tr&gt;<br />&lt;td&gt;Subject&lt;/td&gt;<br />&lt;td&gt;&lt;input name="sub" id="sub" type="text" size="75"&gt;&lt;/td&gt;<br />&lt;/tr&gt;<br />&lt;tr&gt;<br />&lt;td&gt;Name:&lt;/td&gt;<br />&lt;td&gt;&lt;input name="name" id="name" type="text"&gt;&lt;/td&gt;<br />&lt;/tr&gt;<br />&lt;tr&gt;<br />&lt;td&gt;Email&lt;/td&gt;<br />&lt;td&gt;&lt;input name="email" id="email" type="text"&gt;&lt;/td&gt;<br />&lt;/tr&gt;<br />&lt;tr&gt;<br />&lt;td&gt;Message&lt;/td&gt;<br />&lt;td&gt;&lt;textarea name="msg" cols="60" rows="5" id="msg"&gt;&lt;/textarea&gt;&lt;/td&gt;<br />&lt;/tr&gt;<br />&lt;tr&gt;<br />&lt;td&gt;&lt;input type="submit" name="Submit" value="Submit"&gt;<br />&lt;/tr&gt;<br />&lt;/form&gt;<br />&lt;/table&gt;<br />&lt;/body&gt;<br />&lt;/html&gt;<br /><br />In above code we have created contact us fields for the end user. As this is Simple contact form in php hence i used only name, subject,email and message fields. You can add more. After clicking submit button "php_contact_us.php" page will be called. This is the php contact page where we fetch the data of contact.html and send it using <a href="http://phpcodeforbeginner.blogspot.com/2012/12/mail-funtion-in-php.html">php mail function</a>.<br /><br /><b>Now we will create "php_contact_us.php" page. In this page we write our php coding to send contact/feedback mail to admin of website.Copy the below code and save as .php_contact_us.php".</b><br /><br />&lt;?php<br />$subject = $_POST['sub'];<br />$name = $_POST['name'];<br />$from = $_POST['email'];<br />$message = $_POST['msg'];<br />$to = "xyz@receiveremail.com";<br />$send_email = mail($to,$subject,$message);<br />if($send_email){<br /><span class="Apple-tab-span" style="white-space: pre;"> </span>echo "Your message is successfully sent!!!";<br />}else{<br /><span class="Apple-tab-span" style="white-space: pre;"> </span>echo "Error in sending contact email!!!";<br />}<br />?&gt;<br /><br />In above code we use $subject to store subject of contact us form. Similarly we have used $name for the Senders name, $from for storing sender email address, $message for you message of feedback, and very important $to where receivers address is set.<br />After storing this data into variable now we have used <a href="http://phpcodeforbeginner.blogspot.com/2012/12/mail-funtion-in-php.html">php mail function</a> to send the mail. After sending mail we are checking is mail sent proper or not. If it is successfully sent then we will show greeting message other wise some error message.</div>https://www.phptutorialforbeginners.com/2013/01/simple-contact-us-form-in-php-php.htmlnoreply@blogger.com (Anil Gupta)1tag:blogger.com,1999:blog-2100928329644461483.post-7669667157166467192Wed, 23 Jan 2013 07:26:00 +00002013-03-07T13:47:09.504+05:30horizontal menuPHPphp simple dynamic menudynamic menu in php from databasedynamic menu in phpnavigation barmake dynamic menu phphow to create dynamic menu in phpphp dynamic menu tutorialPHP Dynamic Drop Down Menu, Horizontal Menu in PHP | PHP Tutorial for Beginners<div dir="ltr" style="text-align: left;" trbidi="on"><br /><b><span style="color: blue;">What is Menu bar or Horizontal menu?</span></b><br />Menu bar or Horizontal menu is one top most element of any website from where user can navigate to multiple pages. It Helps the user of your site to easily find out element for which he came.<br /><br />Whenever we see or create a website the top most element is <b>Navigation menu</b> or <b>Drop down menu</b> or <b>Horizontal menu</b>. We can&nbsp;Google&nbsp;and get lots of code which create css menu bar which is static. But if we want to create&nbsp;<b>dynamic&nbsp;drop down menu bar</b> then only this code will not help.

The list of menu items inserted in coding will be shown in menu until and unless we change or add them through menu code.<br />Where as the dynamic menu is one which show the menu items fetched from database table.

As jQuery is lightweight, it is easier to load in your website and has fast responce. With help of jQuery it much easier to use JavaScript on your website.<br />Jquery eliminates the many lines of code which we are doing in javascript and make them available with help of single method.<br /><br /><span style="color: blue;"><b><u>What is AJAX?</u></b></span><br />AJAX stand for Asynchronous JavaScript and XML. it is used for creating dynamic and fast web pages. Since AJAX is Asynchronous, it helps in updating a part of web page with out reloading the whole page.<br /><br /><b><span style="color: blue;"><u>What About jQuery and AJAX?</u></span></b><br />The combination of jquery and ajax provide powerfull functionality. With jquery ajax you can make request for text or html from your &nbsp;remote server. If data is large you can use json to receive them. After receiving ajax response we can use them in our html page.<br /><br />jQuery provides some powerful set of jQuery AJAX API’s to handle AJAX requests. In normal way of making AJAX calls using JavaScript is a little bit odd as you have to first create an XMLHttpRequest object that depends on the browser and then make an AJAX call. Also sending a form data using AJAX is also bit difficult if we use normal JavaScript approach of calling AJAX.<br />jQuery provides simple yet powerfull functions which have extended the JavaScript AJAX methods and provide more flexible way. Let us see way of doing AJAX things in jQuery.<br /><br />In this tutorial of php code for beginners we will show you how to use Jquery Ajax in your php form.<br />Lets start... To use Jquery Ajax we need to&nbsp;create&nbsp;two files, In first file our html php code present from where we do ajax request. in second file we process the ajax request and return the result to first page.<br /><br /><b><span style="color: blue;">Step 1:-</span></b> <b><u>Create a school.php file and put this code in it</u>.</b><br /><br />&lt;html&gt;<br />&lt;head&gt;<br />&lt;script src="http://code.jquery.com/jquery-latest.js"&gt;&lt;/script&gt;<br />&lt;script&gt;<br />function getdetails(){<br /><span class="Apple-tab-span" style="white-space: pre;"> </span>var name = $('#name').val();<br /><span class="Apple-tab-span" style="white-space: pre;"> </span>var rno = $('#rno').val();<br /><span class="Apple-tab-span" style="white-space: pre;"> </span>$.ajax({<br /><span class="Apple-tab-span" style="white-space: pre;"> </span>type: "POST",<br /><span class="Apple-tab-span" style="white-space: pre;"> </span>url: "details.php",<br /><span class="Apple-tab-span" style="white-space: pre;"> </span>data: {fname:name, id:rno}<br /><span class="Apple-tab-span" style="white-space: pre;"> </span>}).done(function( result ) {<br /><span class="Apple-tab-span" style="white-space: pre;"> </span>$("#msg").html( " Address of Roll no " +rno +" is "+result );<br /><span class="Apple-tab-span" style="white-space: pre;"> </span>});<br />}<br />&lt;/script&gt;<br />&lt;/head&gt;<br />&lt;body&gt;<br />&lt;table&gt;<br />&lt;tr&gt;<br />&lt;td&gt;Your Name:&lt;/td&gt;<br />&lt;td&gt;&lt;input type="text" name="name" id="name" /&gt;&lt;td&gt;<br />&lt;/tr&gt;<br />&lt;tr&gt;<br />&lt;td&gt;Roll Number:&lt;/td&gt;<br />&lt;td&gt;&lt;input type="text" name="rno" id="rno" /&gt;&lt;td&gt;<br />&lt;/tr&gt;<br />&lt;tr&gt;<br />&lt;td&gt;&lt;/td&gt;<br />&lt;td&gt;&lt;input type="button" name="submit" id="submit" value="submit" onClick = "getdetails()" /&gt;&lt;/td&gt;<br />&lt;/tr&gt;<br />&lt;/table&gt;<br />&lt;div id="msg"&gt;&lt;/div&gt;<br />&lt;/body&gt;<br />&lt;/html&gt;<br /><br />In&nbsp;above&nbsp;code we are taking name and roll no of student and pass this to details.php using jquery ajax.<br /><br /><b><span style="color: blue;">Step 2:-</span></b> <b><u>Create details.php and put the below code in it</u>.</b><br /><br />&lt;?php<br />$name = $_POST['fname'];<br />$rno = $_POST['id'];<br /><br />$con = mysql_connect("localhost","root","");<br />$db= mysql_select_db("school", $con);<br />$sql = "SELECT address from students where name='".$name."' AND rno=".$rno;<br />$result = mysql_query($sql,$con);<br />$row=mysql_fetch_array($result);<br />echo $row['address'];<br />?&gt;<br /><br />In above code we are getting address of&nbsp;student&nbsp;with help of his name and roll number.<br /><br /><b>Note: We can do this with help of normal coding but the&nbsp;difference&nbsp;here is we are getting result without refreshing the page and&nbsp;that's&nbsp;the magic of jquery Ajax.</b><br /><br />Don't forget to create database named "school" and table name "students". table student contain the&nbsp;fields&nbsp;name, rno and address.<br /><br />Hope this php tutorial is useful for you.

To perform basic queries from within MySQL is very easy.This tutorial of phpcodeforbeginners will show you mysql database connection in php.<br /><br />The first thing to do is connect to the database. To connect to mysql databse we use function mysql_connect().<br />Syntax of mysql_connect():-<br />mysql_connect(hostname, username, password)<br /><br />Here "hostname" is name of your host(like 'localhost'), "username" is username of your host(For localhost it is 'roo') and "password" is password of your host site(Default is '').<br /><b>Example:-</b><br />&lt;?php<br />$hostname = "localhost";<br />$username = "root";<br />$password = "";<br /><br />$conn = mysql_connect($hostname, $username, $password) or die("Unable to connect");<br />echo "Connected to MySQL";<br />?&gt;<br /><br />After successfull connection you should see "Connected to MySQL" when you run this script. If you can't connect to the server, make sure your password, username and hostname are correct.<br /><br />Now we have created connection object, next step is to select a database to work with. To select database we use function mysql_select_db() with connection object.<br /><br /><b>Example:-</b><br />&lt;?php<br />//selecting a database with name phptutorials.<br />$database = mysql_select_db("phptutorials",$conn)<br />&nbsp; or die("Could not select phptutorials");<br />?&gt;<br /><br />Now database is selected, let's try and run some queries. The function used to perform queries is named - mysql_query(). The function returns a resource that contains the results of the query, called the result set. To examine the result we're going to use the mysql_fetch_array function, which returns the results row by row.<br /><br /><b>Example:-</b><br />&lt;?php<br />$result = mysql_query("SELECT id, name, address FROM students");<br />while ($row = mysql_fetch_array($result)) {<br />&nbsp; &nbsp;echo "ID:".$row{'id'}." Name:".$row{'name'}." Address:".$row{'year'}."&lt;br&gt;";<br />}<br />?&gt;<br /><br />Finally, we close the connection.<br /><br />&lt;?php<br />mysql_close($conn);<br />?&gt;<br /><br />Here is the full code:<br /><br />&lt;?php<br />$hostname = "localhost";<br />$username = "root";<br />$password = "";<br /><br />//connection to the database<br />$conn = mysql_connect($hostname, $username, $password) or die("Unable to connect");<br />echo "Connected to MySQL";<br /><br />//select database phptutorials<br />$database = mysql_select_db("phptutorials",$conn) or die("Could not select phptutorials");<br /><br />//execute the SQL query and return records<br />$result = mysql_query("SELECT id, name, address FROM students");<br /><br />//fetch tha data from the database<br />while ($row = mysql_fetch_array($result)){<br />&nbsp; &nbsp;echo "ID:".$row{'id'}." Name:".$row{'name'}." Address:".$row{'year'}."&lt;br&gt;";<br />}<br />//close the connection<br />mysql_close($conn);<br />?&gt;</div>https://www.phptutorialforbeginners.com/2013/01/mysql-database-connection-in-php-php.htmlnoreply@blogger.com (Anil Gupta)0tag:blogger.com,1999:blog-2100928329644461483.post-3067605021757270379Tue, 15 Jan 2013 08:44:00 +00002013-04-18T17:31:44.774+05:30JQUERYcheck a checkbox using jqueryjava script for validationjquery for validationvalidate form with multiple checkboxcheckbox jquery validationcheckbox validation using jqueryJQuery Validation for Multiple Checkbox Form | PHP Tutorials For Beginners<div dir="ltr" style="text-align: left;" trbidi="on"><br />Sometime we come to the situation where we want to validate the form with multiple checkbox and&nbsp;at least&nbsp;one checkbox is selected.<br />In this tutorial of <a href="http://phpcodeforbeginner.blogspot.in/">phpcodeforbeginner.blogspot.in</a> we validate form with multiple checkboxes with use of jQuery. The result will return true only if atleast one checkbox is selected.<br /><br />In below example we create a html page which have multiple checkboxes.
