PHP: check if any posted vars are empty - form: all fields required

Question

Is there a simpler function to something like this:

if (isset($_POST[\'Submit\'])) {
    if ($_POST[\'login\'] == \"\" || $_POST[\'password\'] == \"\" || $_P         


        

Answer 1

foreach($_POST as $key=>$value)
{

   if(empty(trim($value))
        echo "$key input required of value ";

}
