IDs Over 10 Being Split

[Titan85]

I have made a delete script with multiple delete. Everything runs great until the delete ID being fed hits 10 or more, then it splits it into 1 and 0 instead of 10. Here is the delete PHP:

###### If Delete Was Hit ######
            else if ($_POST['delete']) {    
                    $links = mysql_query("SELECT * FROM `cms_nav` ORDER BY id ASC") or die ("Error Getting Links! \n <br /> \n" .mysql_error()); 
                    $chk = mysql_num_rows($links);
                for ($i=0; $i<$chk; $i++) {
                    $del_id = $checkbox[$i];
                    $del = mysql_query("DELETE FROM `cms_nav` WHERE id = '$del_id'") or die ("Error Deleting Selected! \n<br />\n" .mysql_error());
                    echo('Del ID: '.$del_id.' ');
                }
                echo('<meta http-equiv="refresh" content="2;URL=nav.php" /> <div class="message">The selected links have been deleted</div>'); 
            }
            ###### ################# ###### 

When I this code added to the script and the ID to be deleted is 10, it echos Del ID: 1 Del ID: 0

echo('Del ID: '.$del_id.' ');

Here is the HTML sending the information:

<input type="checkbox" name="checkbox" value="<?php echo $l['id']; ?>" />

Anyone know why it is doing this?

Thanks in advance

It isn't an array. You're looping over the characters of the string here:

                for ($i=0; $i<$chk; $i++) {
                    $del_id = $checkbox[$i];

In PHP, if you want an array from POST data the element names have to end with [].

So the code should be

<input type="checkbox" name="checkbox[]" value="<?php echo $l['id']; ?>" />

or do you mean:

$del_id = $checkbox[$i][];

<input type="checkbox" name="checkbox[]" value="<?php echo $l['id']; ?>">
