Hi all,
I keep getting this error:
Notice: Undefined index: tutor_id in /usr/local/..........
What does "undefined index" exactly mean?? I did a search on the web but
couldn't find any solutions.
The line that cause this error is as follow:
$tutor_id = $_POST["tutor_id"];
.
.
.
.if($action == "edit")
{
$sql = mysql_query ("SELECT * FROM tutor WHERE tutor_id='$tutor_id'");
$row = mysql_fetch_array($sql);
etc.....
Hope to get some help here soon...thanks in advance.
Irin.
