foreach question.

I have a multiple checkbox page. I have handled these before, well. However, this time I am getting a strange error.

 

Here it is:

Warning: Invalid argument supplied for foreach() in C:\wamp\www\TheSportZone Store\admin\manageAdmin.php on line 10

 

Here is Line 10:

foreach($_POST['del'] as $id){

 

Entire foreach body:

		foreach($_POST['del'] as $id){
			mysql_query("DELETE FROM ".TBL_ADMINS." WHERE id = '$id'");
		}

 

Any ideas? I have done this before, as such, and it worked well.

Hmm, something like this?

 

		if(is_array($_POST['del'])){
			foreach($_POST['del'] as $id){
				mysql_query("DELETE FROM ".TBL_ADMINS." WHERE id = '$id'");
			}
		}else
			mysql_query("DELETE FROM ".TBL_ADMINS." WHERE id = '$id'");

This

<input type="checkbox" name="del" id="del" value="<?php echo $id; ?>">

will not create an array in the processing script.

This

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

will
