AJAX/Jquery not deleting row from MySQL table - php

Question

I am trying to use AJAX and jQuery to delete a record from a table. The row is being removed from the page view as required, but not from the table.
Im using the following files and related sections:
Query
$result = mysql_query("SELECT id,name FROM myTable");
Query result:
while($row = mysql_fetch_array($result))
{
$id1=$row['id'];
$dataname=$row['name'];
?>
<div class="show">
<span class="name"><?php echo $dataname; ?></span><br><span class="name"><?php echo $id1; ?></span>
<span class="action">Delete</span>
</div>
<?php
}
?>
AJAX Script
<script type="text/javascript">
$(function() {
$(".delete").click(function(){
var element = $(this);
var del_id = element.attr("id");
var info = 'id=' + del_id;
if(confirm("Are you sure you want to delete this?"))
{
$.ajax({
type: "POST",
url: "delete.php",
data: info,
success: function(){
}
});
$(this).parents(".show").animate({ backgroundColor: "#003" }, "slow")
.animate({ opacity: "hide" }, "slow");
}
return false;
});
});
</script>
delete.php
<?php
include('db.php');
if($_POST['id'])
{
$id=mysql_real_escape_string($_POST['id']);
$delete = "DELETE FROM `testdb` WHERE id = '$id1' ";
mysql_query($delete);
}
?>

Answer 1

$id=mysql_real_escape_string($_POST['id']);
$delete = "DELETE FROM `testdb` WHERE id = '$id1' ";
You are using $id1 in the delete statement, it should be $id
$delete = "DELETE FROM `testdb` WHERE id = '$id'";
NOTE : Your code is vulnerable to sql injection, start using
preparedStatement with mysqli_ or PDO
UPDATE: Using PDO to do the delete operation
error_reporting(E_ALL);
ini_set('display_errors', '1');
try {
$pdo = new PDO('mysql:host=localhost;dbname=test', '****', '****');
} catch (PDOException $e) {
print "Error!: " . $e->getMessage() . "<br/>";
die();
}
$id = $_POST['id'] ;
$sql = "DELETE FROM testdb WHERE id = :id ";
$stmt = $pdo->prepare($sql);
$stmt->bindParam(':id', $id, PDO::PARAM_INT);
$stmt->execute();
