Instances of objects in a class - php

Question

I have a form building a processing class that I have developed to handle any and all form processing on a page.
I am running into a problem when I have mulitple forms on a page I am building each form with an instance of the class:
$form2 = new newForm('submitform2', 'post.contact.php', '100%');
$form2->setHandler('#canWe');
$form2->html('<div class="half">');
$form2->addText('name', 'Name:');
$form2->html('</div>');
$form2->html('<div class="halfNoMarg">');
$form2->addEmail('email_address', 'E-Mail Address:');
$form2->html('</div>');
$form2->html('<div class="half">');
$form2->addUrl('website', 'Website URL:');
$form2->html('</div>');
$form2->html('<div class="halfNoMarg">');
$form2->addText('phone', 'Phone Number:');
$form2->html('</div>');
$form2->addTextArea('about_business', 'Tell Us About Your Business:');
$form2->addSubmitButton('Find Out Now!');
$form2->getPost();
$form2->outputForm();
AND
$form = new newForm('submitform', 'post.contact.php', '100%');
$form->addText('name', 'Name:');
$form->addEmail('email_address', 'E-Mail Address:');
$form->addUrl('website', 'Website URL:');
$form->addText('phone', 'Phone Number:');
$form->addTextArea('about_business', 'Tell Us About Your Business:');
$form->addSubmitButton('Find Out Now!');
$form->getPost();
$form->outputForm();
When the class processes the form and spits out the errors for the missing fields etc. each of the forms displays the errors and not just the form object that is being processed.
Basically the output is affecting each instance of the class and not just the one being processed.
I can include the class file if anyone needs it to help out (its 650 lines so didn't want to include in the post).
Thanks in advance for any help provided.

EDIT ADDING IN THE POST FUNCTION
//get the post data and return a cleaned array of information if the post passes the pre check
public function getPost()
{
//if post tests all passed then lets create the array of elements and load the processing file.
if ($this->checkPost() === true) {
$cleanedPost = $this->cleanPost;
//get the post processing file
if (file_exists($this->processFile)) {
require_once($this->processFile);
//$this->postMessage($this->successMessage, 'confirm');
} else {
$this->postMessage('Processing File Not Found:<em>' . $this->processFile . '</em>', 'error');
}
return $this->cleanPost;
} else {
return false;
}
}
//output the form to the screen
public function outputForm()
{
//echo spl_object_hash($this);
if($this->handler !== null){
$this->handler = 'action="'.$this->handler.'"';
}
$return = '<form id="' . $this->formName . '" method="' . $this->method . '"'. $this->handler .' enctype="multipart/form-data" style="width:' . $this->width . '" >';
if(!empty($this->message)){
$return .= '<div class="errorMessage">' . $this->message . '</div>';
}
$return .= $this->output;
$return .= '</form>';
echo $return;
}
more post handling code
//check post before we handle it
public function checkPost()
{
//go through the entire post and process information as needed
if (!empty($_POST)) {
foreach ($this->postCheck AS $postVar => $item) {
if (is_array($item)) {
//addItemTo cleanPost
if(isset($_POST[$postVar])){
$this->addToCleanedPost($postVar, $_POST[$postVar]);
}else{
$this->cleanPost[$postVar] = null;
}
switch ($item['type']) {
//validate emails
case 'email':
//check valid email
if (isset($this->cleanPost[$postVar]) && !$this->validEmail($this->cleanPost[$postVar])) {
$this->postMessage('Email Address is invalid');
}
break;
//validate and verify password
case 'password':
if ($item['verify'] === true) {
//validate password against other
if (!$this->verifyPassword($this->cleanPost['password'], $this->cleanPost['password2'])) {
$this->postMessage('Passwords do not match');
}
} else {
if (empty($this->cleanPost[$postVar]) && $item['req'] === 1) {
$this->postMessage($postVar . ': Please enter a password');
}
}
break;
//validate checkboxes
case 'checkbox':
if ($item['req'] === 1 && $this->validateCheckBox($postVar) === 0) {
$this->postMessage($postVar . ' must be checked');
} else {
$this->cleanPost[$postVar] = $this->validateCheckBox($postVar);
}
break;
//handle url
case 'url':
//first we need to handle making the url format properly
if(isset($this->cleanPost[$postVar])){
$url = $this->validUrl($this->cleanPost[$postVar]);
//now we do the final checking of the url and make sure it is a valid url before we move forwards
if ($item['req'] === 1 && $url === null) {
$this->postMessage($postVar . ' must be a valid URL');
}else{
$this->cleanPost[$postVar] = $url;
}
}
break;
//handle text and text areas
case 'text':
case 'textarea':
if (isset($_POST[$postVar])) {
//check for a bypass on the min required characters
if (isset($item['bypass']) && $item['bypass'] === true || $this->minBypass === true) {
$bypassMinCheck = true;
} else {
$bypassMinCheck = false;
}
//process the item
if ($item['req'] === 1 && $bypassMinCheck === false && strlen($this->cleanPost[$postVar]) < 2) {
$this->postMessage($postVar . ' is too short');
} else {
if (!empty($this->cleanPost[$postVar]) && $bypassMinCheck === false) {
if (strlen($_POST[$postVar]) < 2) {
$this->postMessage($postVar . ' is too short');
}
}
}
}
break;
//handle other inputs
default:
if (empty($_POST[$postVar]) && $item['req'] === 1) {
$this->postMessage($postVar . ' cannot be left empty');
}
break;
}
}
}
} else {
return false;
}
//return the success or failure of the prepost test
if (empty($this->message)) {
return true;
} else {
return false;
}
