How To Edit Data on Edit.php Page With The Help of GET () Method

1 First we receive id on edit.php page from data fetch table page like below.

<form action="edit.php?id=<?php echo $id; ?>" method="post" enctype="multipart/form-data">
 <input type="image"  src="images/icon/icon.png"   width="50"   id="editm" name="editm" value="<?php echo $data['id'];?>" placeholder="Movie Name" required="">
<input type="hidden"   id="idedit" name="idedit" value="<?php echo $data['id'];?>" placeholder="Movie Name" required="">
    </form> 

2 Then receive data from DB table with help of id like below and then run update query for update data in database like below example.

<?php
include("config.php");
$id = isset($_GET['id']) ? $_GET['id'] : '';
$query = "SELECT * from school_classmaster where id='".$id."'"; 
$result = mysql_query( $query) ;
$row = mysql_fetch_array($result);
?>
<?php

if(isset($_POST['submit']) )
{
echo $update="UPDATE `school_classmaster` SET `name` = '".$_POST['name']."', `section` = '".$_POST['section']."', `student` = '".$_POST['student']."' WHERE `id` = '".$_POST['id']."'";
$update1=mysql_query( $update) ;
$status = "Record Updated Successfully. </br></br>
<a href='class.php'>View Updated Record</a>";
echo '<p style="color:#FF0000;">'.$status.'</p>';
header('Location: class.php');
}
?>
<form name="form" method="post" action="edit.php"> 
<p><input type="text" name="name" placeholder="Enter Name" 
required value="<?php echo $row['name'];?>" /></p>
<p><input type="text" name="section" placeholder="Enter Section" 
required value="<?php echo $section= $row['section'];?>" /></p>
<p><input type="text" name="student" placeholder="Enter Student" 
required value="<?php echo $student= $row['student'];?>" /></p>
