Question

I have a script which works great for saving users in comma seperated value to MySQL ‘reserve’ field.

eg ‘510,465,8552’

I then have the script below which echos the users name from the comma seperated ‘reserve’ field.
The bit i am struggling with is to be able to click on a delete image next to one of the users and it will delete the users id from the comma seperated value.

    $entries = get_records_sql ("SELECT * FROM development ORDER BY pdorder ASC");  
    foreach($entries as $lesson) {

    $waiting = explode(",", $lesson->reserve);
    foreach($waiting as $unlucky) {
    $reserveuser = get_record("user", "id", $unlucky);

    if($reserveuser->id>1){
echo '<li id="lstno'.$lesson->id.'" name="'.$reserveuser->id.'">'.$reserveuser->firstname.'&nbsp;'.$reserveuser->lastname.' ';
echo '<a href="removereserve.php?id='.$lesson->id.'&reserve='.$reserveuser->id.'"><img title="unenrol" src="delete.gif" /></a>';
        echo '</li>';
        }
    }

Any guidance would be much appreciated, thanks in advance.

Answer 1

Well, if all of the user id’s are saved in one field my approach would be something like this http://codepad.org/KTAJ3ROb

Hope that helps figuring it out!
