Validating My Form, Not Working

e39m5 · March 5, 2006

Ok, I just did a bunch of looking around and found some ways to validate a form. I am trying to just validate the form, no sending to the database yet. I am using 2 different files, one for the functions, and one for the form and actual validation. When I hit submit, I get no feedback, and everything in the boxes dissappear. Here is the link to it running:

[a href=\"http://anylance.blogmyway.com/registration.php\" target=\"_blank\"]http://anylance.blogmyway.com/registration.php[/a]

These are the files:

functions.php
[code]
<?php

function isLetters($element) {
  return !preg_match ("/[^A-z]/", $element);
}
function checkLength($string, $min, $max) {
  $length = strlen ($string);
  if (($length < $min) || ($length > $max)) {
    return FALSE;
  } else {
    return TRUE;
  }
}
function checkEmail($email) {
  $pattern = "/^[A-z0-9\._-]+"
         . "@"
         . "[A-z0-9][A-z0-9-]*"
         . "(\.[A-z0-9_-]+)*"
         . "\.([A-z]{2,6})$/";
  return preg_match ($pattern, $email);
}
function isSame($string1, $string2) {
  if ($string1 != $string2) {
    return FALSE;
  } else {
    return TRUE;
  }
}
function checkPhone($phonenumber,$useareacode=true)
{
if ( preg_match("/^[ ]*[(]{0,1}[ ]*[0-9]{3,3}[ ]*[)]{0,1}[-]{0,1}[ ]*[0-9]{3,3}[ ]*[-]{0,1}[ ]*[0-9]{4,4}[ ]*$/",$phonenumber) || (preg_match("/^[ ]*[0-9]{3,3}[ ]*[-]{0,1}[ ]*[0-9]{4,4}[ ]*$/",$phonenumber) && !$useareacode)) return eregi_replace("[^0-9]", "", $phonenumber);
return FALSE;
}
?>
[/code]

if (isset ($_POST['submit'])) {

    $valid = $fn = checkLength($fname, 1, 30);
    $us = checkLength($username, 5, 30);
    $valid = $valid && $us;

        exit;
    }
} else {
