php check if any of 30 form fields is empty

Question

I have more than 30 fields in a form, and can't believe that I must write an array to check if any of them is empty (likehere)

I need something like js

$_POST[].each function{
 if this is empty...
}

and hope that 'php' as so glorified language has something like this or similar.

if you need a JS method, you need to tag it as such, as you wrote *"I need something like js"* - So is it php or js? your post is unclear. — Funk Forty Niner, May 11 '17 at 10:10
You really should keep the language bashing to a minimum until you have learned the basics — RiggsFolly, May 11 '17 at 10:13

Try this:

foreach($_POST as $post)
{
    if( !empty($post) )
    {
        // your code here
    }
}

`[]` just slip of mind, thanks @RiggsFolly for making it correct. – Mayank Pandeyz May 11 '17 at 10:17
