0

I am building a PHP registration form which takes the following fields for up to 20 athletes:

First Name Middle Initial Last Name
Federation Number Address City State
Zip DOB SSN Phone Email

I am only through 7 of the fields for each fighter and my php file is very large (over 40kb). Is there ANY way to consolidate this code at all? I am also having to validate the information on each field (as I said – 20 athletes x 12 fields = 240 validations on a single page).

If I can send any further code let me know!

<form id="Form"  action="<?php $_SERVER['PHP_SELF']; ?>" method="post" name="Form" onsubmit="return Enroll_Form_Validator(this)">
<p class="title">Your Fighters' Information</p>
<p>Please complete the following fields with your <span style="color:red;"> Fighters' Information</span> to continue your enrollment.</p>
<br />

<?php
    // if $errors is not empty, the form must have failed one or more validation 
    // tests. Loop through each and display them on the page for the user
    if (!empty($errors))
    {
      echo "<div class='error'>Please fix the following errors:\n<ul>";
      foreach ($errors as $error)
        echo "<li>$error</li>\n";

      echo "</ul></div>"; 
    }    
?>

    </table>
<?php } ?>
<div align="right"><input class="enrbutton" type="submit" name="submit" value="Continue" /></div>
</form>

This only goes through 4 athletes and I need it to capture 20. Any ideas? I am forced to keep all 200+ elements in SESSION assuming somebody enrolls 20 athletes.

Throw this code away.
Seperate your html files from your php code.
Use a MVC pattern if you
are ambitious.
Use a validation
class.
Profit!
