[php]if(is_array($_POST[‘fieldname’])) foreach($_POST[‘fieldname’] as $value){

//Do your thing

}[/php]

what if they only check one box to delete, then it would not be an array and this would not work. so you would have to add an else value = post fieldname

Well it would work just it would have 1 entry in the array.

I’m assuming this would work.
[php]if(isset($_POST[‘fieldname’])){
//delete
}[/php]

Otherwise you could try
[php]if($_POST[‘fieldname’] == 1){
//delete
}[/php]

Checked stores 1, unchecked might store 0, so if thats true try 2nd one.

As mentioned by you guys the line " if(is_set($_POST[‘fieldname’]) "…now the filed name here refers to the name of checkbox which i gave as name=“checkbox[]” in the FORM field but i am a bit confused as how to to modify the above line accordingly .
I mean should it be like is_set($_POST[‘checkbox’]) OR is_set($_POST[‘checkbox[]’]) ??

isset($_POST[‘checkbox’])

name=“checkbox”

the [] symbols after checkbox are only a signal to php that it is an array, but checkbox is the name

also I dont know if you checked out the link I sent you but I am going to post the code that was on that link so everyone who reads this will also see it without having to search around 8)
[php]

<?php if (isset($_GET['remove']) && is_numeric($_GET['remove'])) { //Delete here using $_GET['remove'] value } if (isset($_POST['Submit']) && $_POST['Submit'] == 'Remove Selected') { $id = array(); $id = $_POST['removeid']; //print_r($id); if (count($id) > 0) { foreach ($id as $removeid) { //Delete here using $removeid value } } } ?>

Remove	Items	Options
	One	Remove item
	Two	Remove item
	Three	Remove item
Select/Unselect All

[/php]
