<pre><code> $required_fields = array('event_type','accommodation_type','public_user','comments','grand_total');
    $required_fields2 = array('first_name','last_name','gender','age_group');
    $errors = array_merge($errors, check_required_fields($required_fields, $_POST));
    $errors2 = array_merge($errors2, check_required_fields($required_fields2, $_POST));

    $fields_with_lengths = array('event_type' =&gt; 50, 'accommodation_type' =&gt; 50, 'public_user' =&gt; 50,'comments' =&gt; 10000,'grand_total' =&gt; 50);
    $fields_with_lengths2 = array('first_name' =&gt; 50, 'last_name' =&gt; 50, 'gender' =&gt; 50,'age_group' =&gt; 50);
    $errors = array_merge($errors, check_max_field_lengths($fields_with_lengths, $_POST));
    $errors2 = array_merge($errors2, check_max_field_lengths($fields_with_lengths2, $_POST));

    $event_type = trim(mysql_prep($_POST['event_type']));
    $accommodation_type= trim(mysql_prep($_POST['accommodation_type']));
    $public_user = trim(mysql_prep($_POST['public_user']));
    $comments = trim(mysql_prep($_POST['comments']));
    $grand_total = trim(mysql_prep($_POST['grand_total']));

    if (empty($errors)){
        $query = "INSERT INTO event_registration (event_type, accommodation_type, public_user, comments, grand_total) VALUES ('{$event_type}','{$accommodation_type}','{$public_user}','{$comments}','{$grand_total}')";
        $result = mysql_query($query, $connection);

        if($result){

        }
    } else{

        if(count($errors)==1){
            $message = "There was 1 error in the form.";
        } else {
            $message = "There were" . count($errors) . " error in the form.";
        }   
    }

} else { // Form has not been submitted
    $event_type = "";
    $accommodation_type = "";
    $public_user = "";
    $comments = "";
    $grand_total = "";
