asked on Warning: Invalid argument supplied for foreach()
Not sure what I'm doing wrong, but I've been up all night trying to catch up on some work. I'm sure this is just a simple oversight, but the error is occurring on Line 20, which is where I have foreach($_POST[$field] as $key => $line)

{
$fields = array('partnumber','partdescription','qty','cost');
$worknumid = $_POST['workrecordnum'];

PHP var_dump() is your friend. Try var_dump($_POST) just before line 12 and see what you get.
greetings t3chguy, , you do not have "Matching" _POST Key strings in your code you have the name as
name="partnum[]" and name="partdesc[]"
BUT you have the fields as =
$fields = array('partnumber','partde
I would think it should be something like =
$fields = array('partnum','partdesc'
but I am not sure about all you intend to do in your code?
