Form validation with functions

Posted on 16th Feb 2014 07:03 pm by admin

Hi there

I am trying to make a very simple form validation function. I currently have the following

function formValidate($field, $msg) {

if (empty($_POST['$field'])) {
$errors[] = $msg;
} else {
$field = mysqli_real_escape_string($dbc, trim($_POST['$field']));
}

}// end of function

formValidate('form', 'You forgot to enter the form');


When I run the script and enter nothing into the $_POST['form'] field it still executes an empty record into the database.

What am I doing wrong?
