[SOLVED] Form Validation

[TheJoey]

It just not validating anything. Im not good at all with regex but ive gotten this snip of the internet.

Its not displaying errors.

      <?php
      // Function to display form

      function showForm($errorName=false,$errorEmail=false,$errorMesg=false){

      if ($errorName) $errorTextName = "Please enter your name!";

      if ($errorEmail) $errorTextEmail = "Please enter a valid email address!";
  
      if ($errorMesg) $errorTextMesg = "Please leave a longer message!";
   
      echo '<form action="form.php" method="POST"><table>';

      // Display name field an error if needed
  
      echo '<tr><td>Name:</td><td><input type="text" name="name"></td></tr>';
  
      if ($errorName) echo "<tr><td colspan='2'>$errorTextName</td></tr>";

      // Display email field an error if needed
  
      echo '<tr><td>Email:</td><td><input type="text" name="email"></td></tr>';
      if ($errorEmail) echo "<tr><td colspan='2'>$errorTextEmail</td></tr>";
  
      // Display message field an error if needed
  
      echo '<tr><td>Message:</td><td><textarea name="mesg"></textarea></td></tr>';
      if ($errorMesg) echo "<tr><td colspan='2'>$errorTextMesg</td></tr>";
      echo '<tr><td><input type="submit" name="SubmitForm" value="Send"></td></tr>';
      echo '<form>';
      }
      if (!isset($_POST['SubmitForm'])) {
      showForm();
      } else {
      //Init error variables
      $errorName = false;
      $errorEmail = false;
      $errorMesg = false;
      $name = isset($_POST['name']) ? trim($_POST['name']) : '';
      $email = isset($_POST['email']) ? trim($_POST['email']) : '';
      $mesg = isset($_POST['mesg']) ? trim($_POST['mesg']) : '';
      if (!eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $email)) $errorEmail = true;
      if (strlen($name)<3) $errorName = true;
      if (strlen($mesg)<10) $errorMesg = true;
      // Display the form again as there was an error
      if ($errorName || $errorEmail || $errorMesg) {
      showForm($errorName,$errorEmail,$errorMesg);
      } else {
      echo 'Submission was success!';
      }
      }
      ?>

So, what's your question? If you want to have good validation, why not try formmail from tectite.com

His problem was this:

Its not displaying errors.

 

I looked through the code and tested it out and it worked perfectly for me. Sorry TheJoey, I'm just not seeing any problems.

[TheJoey]

there arent any problems, but it isnt validating.

@ is being accepted as proper email

whereas it should be name@mail.com

there arent any syntax errors, its just not doing what its meant to.

sorry i posted the wrong code, i seemed to have lost the one i needed questions with.
