Which field do you need to validate? Lets assume that it’s the first name… First, I would put the form itself into a function so that you can reuse it if the validation fails. Just pass the form function an array that represents the $\_POST array. Then echo the appropriate array key in the form field value attribute like so:

```php

echo "<input type=\"text\" name=\"txtFirstName\" value=\"$postValues['txtFirstName']\" />";

```

Then, after submission:

```php

if(isset($_POST['submit'])) 
{
     //you could use regular expression matching for phone, email
     if($_POST['txtFirstName'] != '')
     {
          $firstName = $_POST['txtFirstName'];
          $lastName = $_POST['txtLastName'];
          //etc...
     }
     else
     {
         echo "<h2>ERROR MESSAGE</h2>";
         $form = formFunction($_POST);
     }
}
else
{
     echo "<h2>FILL OUT FORM</h2>";
     $form = formFunction();
}

```

But I still like to use Javascript validation because it validates before the form is submitted to the server, so it is a little bit quicker
