First, to be clear, you *can* use elements of arrays as the 'name=' in forms, as in

<input type="checkbox" name="slotsel[$i]" $slotchk[$i]>
  <input type='hidden' name="titles[$topic]" value="$titles[$topic]">

as you seem to be trying. I've been doing it for years; associative arrays also work. The result is that all the inputs of a form can be put into an array, be retrieved in PHP using a single read of $_POST, and be iterated in a loop in PHP; I believe they can also be iterated in a loop in javascript. Contrast this with putting each input value into a separate variable.

$_POST is empty (undefined) the first time a script is run; in this case, that warning is to be exxpected.

In line 9 (<select name='add_item1[]' size=5 multiple>), try putting an index between the brackets.

I have already trying to use elements of arrays but still undefined index.

$_POST is empty (undefined) the first time a script is run; in this case, that warning is to be exxpected.

So, I can get input the warning. on java script isn't? how can I put in to my php syntax? any code?

In line 9 (<select name='add_item1[]' size=5 multiple>), try putting an index between the brackets.

I have already trying but still cannot solve.

do i have to give warning at an early stage?
any syntax?

thanks for your help..

Do you mean something like

if (isset($_POST['add_item1'] {
Member Avatar for simplypixie

Undefined index is just a warning, not an error and it is just advising to check if the variable exists or has a value so all you have to do is out an if statement in your code and in your case around the whole php by the look of it:

<?php
if (isset($_POST['add_item1'])) { 
// Your current php code here
}
?>
