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'] == "" || $_POST['confirm'] == "" || $_POST['name'] == "" || $_POST['phone'] == "" || $_POST['email'] == "") {         echo "error: all fields are required";     } else {         echo "proceed...";     } } 

Answer 1

Something like this:

// Required field names $required = array('login', 'password', 'confirm', 'name', 'phone', 'email');  // Loop over field names, make sure each one exists and is not empty $error = false; foreach($required as $field) {   if (empty($_POST[$field])) {     $error = true;   } }  if ($error) {   echo "All fields are required."; } else {   echo "Proceed..."; } 

Answer 2

if( isset( $_POST['login'] ) &&  strlen( $_POST['login'] )) {   // valid $_POST['login'] is set and its value is greater than zero } else {   //error either $_POST['login'] is not set or $_POST['login'] is empty form field }
