Question

I have some form fields that when a form is submitted creates an array within the $_POST, I needing to check the this array has atleast 4 keys, how can I check that? I have no idea

Answer 1

try:

<?php 
if(count($_POST) >= 4):
//Do your stuff
else:
//Do your error stuff
endif;

If you want to check an array within $_POST as apose to $_POST itself use

count($_POST['name_of_key_to_array_you_want_to_count'])
