data.php
<?php
mysql_connect("localhost","root","");
mysql_select_db("dbtuts");
$sql_query="SELECT * FROM users";
$result_set=mysql_query($sql_query);
?>
<table align="center">

</table>OutPut:
By selecting the data to be edited the another php file will be displayed with the selected data as follow :
Now we need to fetch the selected data From the QueryString URL.
http://localhost/edit-data/edit_data.php?edit_id=36$_GET['edit_id'] : is the php variable that get the QueryString ID From The URL.
if(isset($_GET['edit_id']))
{
$sql_query="SELECT * FROM users WHERE user_id=".$_GET['edit_id'];
$result_set=mysql_query($sql_query);
$row=mysql_fetch_array($result_set);
}By fetching all the selected data you can Update them , But for Viewing the data in the textbox do as follow.
<input type="text" name="first_name" value="<?php echo $row['first_name']; ?>" />Now The Main Update Condition :
if(isset($_POST['btn-update']))
{
// variables for input data
$first_name = $_POST['first_name'];
$last_name = $_POST['last_name'];
$city_name = $_POST['city_name'];
