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

I did it like this:

$missing = array();
 foreach ($_POST as $key => $value) { if ($value == "") { array_push($missing, $key);}}
 if (count($missing) > 0) {
  echo "Required fields found empty: ";
  foreach ($missing as $k => $v) { echo $v." ";}
  } else {
  unset($missing);
  // do your stuff here with the $_POST
  }
