[SOLVED] Array, foreach and checkboxes.

[zero118]

I keep getting an invalid foreach argument here...

 

 

			case 'move_loc':
				foreach ($_POST[ 'move' ] as $key )
				{
					$update ("UPDATE recert SET location =" . $_POST[ 'location' ] . " WHERE serial =
'$key'");			
				}
			break;

 

 

My form uses 'move' as the checkbox names and I am attempting to update multiple rows at one time.  I do not have much experience with foreach so any help is appreciated.

Are you sure you're passing these values as arrays from your form.

 

i.e. -

 

 

Before your switch, try to print the array:

 

print_r($_POST['move']);

If the operand is not an arrray, then you're going to have an issue with foreach.  Under certain circumstances your $_POST['move'] probably either doesn't exist at all or isn't an array.  My recommendation for a quick examination of this is to use print_r() on the $_POST['move'] variable to understand what's happening better.

Yes, I can see the array just fine.  But it is still telling me the argument is invalid.  Could it have anything to do with the format of the contents?  A sample would be FVRB-8239

I apologize, the error was elsewhere.  Sometimes all you need is someone to make you look at the code a little harder =-)  The array was fine, it was a query that was causing the issue.

Be careful, cause you may want the value of each element of the array rather than the key.  You can obtain the value by adding this to your foreach loop:

 

foreach ($_POST['move'] as $key => $value)
