Form Validation and Data being Cleared
Posted: Thu Dec 31, 2009 12:15 pm
I am using a basic form validator script, but the one problem I'm having is if errors are found, like a field is required, I get the error message, but all the data has been cleared from the form that the user already entered. Is there a way to keep the data from being lost that they have already entered? Here is my code.
<?php
require_once 'formvalidator.php';
$show_form=true;
if(isset($_POST['Submit']))
{
$validator = new FormValidator();
$validator->addValidation('enroll_lnm', 'req', 'Please fill in Last Name');
$validator->addValidation("enroll_fnm", "req", "Please fill in First Name");
$validator->addValidation("enroll_4ssn", "req", "Please fill in Last 4 Digits of SSN");
$validator->addValidation("enroll_raddr", "req", "Please fill in Street Address");
$validator->addValidation("enroll_rcity", "req", "Please fill in City");
$validator->addValidation("enroll_rst", "req", "Please fill in State");
$validator->addValidation("enroll_rzip", "req", "Please fill in Zip Code");
$validator->addValidation("enroll_bdate", "req", "Please fill in Birth Date");
$validator->addValidation("enroll_ph", "req", "Please fill in Phone Number");
$validator->addValidation("enroll_email", "email", "Please fill in Valid Email Address");
if($validator->ValidateForm())
{
echo "<B>Enrollment Successful - You will recieve an email confirming this enrollment.</B>";
$show_form=false;
}
else
{
echo "<B>Validation Erros:</B>";
$error_hash = $validator->GetErrors();
foreach($error_hash as $inpname => $inp_err)
{
echo "<p>$inpname: $inp_err</p>\n";
}
}
}
if (true == $show_form)
{
?>
