Shortcut for checking if all $_POST fields are filled in php

Question

I know that I can check if the superglobal $_POST is empty or not by using

empty / isset

However, I have many fields here. Is there any shortcut to check if all fields are filled? Instead of doing

if (!empty($_POST['a']) || !empty($_POST['b']) || !empty($_POST['c']) || !empty($_POST['d']).... ad nauseum)

Thanks in advance!

Answer 1

You can use array_filter and compare both counts

if(count(array_filter($_POST))!=count($_POST)){
    echo "Something is empty";
}

Answer 2

You can loop through the $_POST variable.

For example:

$messages=array();
foreach($_POST as $key => $value){
    if(empty($value))
        $messages[] = "Hey you forgot to fill this field: $key";
} 
print_r($messages);
