Delete values selected using checkbox

I want to delete values that has been selected using checkbox. I am using this script though its not giving any error but its not working

please help it out.

for checkbox

<input name="checkbox[]" type="checkbox" value="<?=$row['s_id']?>">

for delete button

<input type="submit" name="delete" value="Delete">

for query

if(isset($_POST['delete']))
{

$count=array();
$count=$_POST['checkbox'];
for($i=0;$i<count($count);$i++){
      开发者_如何学JAVA  $del_id = $checkbox['$i'];
        $sql = "DELETE FROM t_s_list WHERE s_id='$del_id'";
        $result = mysql_query($sql);
}
$NEW="Selected records Deleted";
}
var_dump($_POST['checkbox']);
var_dump($count);

Check the name of your delete button. $_POST['delete'] needs the name to be 'delete'.

Also please check $del_id = $checkbox['$i']; It should be $del_id = $checkbox[$i];

And for security sake

$sql = "DELETE FROM t_s_list WHERE s_id='".mysql_real_escape_string($del_id)."'";

You write:

<input type="submit" name="Submit" value="Delete">

but

$_POST['delete']

Use var_dump($_POST) to see what the issue is here, if you don't see it.

Also, where is your SQL Injection protection?
