CakePHP Multiple Named Parameters in Link - php

Question

I'm using a link to name a parameter that I need in a form on the next page. Here is the link code:
echo $this->Html->link('Email', array('controller' => 'emails', 'action' => 'add', 'contact_email' => $model), array('class' => 'button add'));
The purpose of this is to save an email to the database, and then send the email (both of which work).
I want to return to the page that they were on when they clicked the link, but don't know how to access that model and id after they've gone through two more page...
Here's add.ctp
<div class="universities form">
<?php echo $this->Form->create('Email');?>
<fieldset>
<legend><?php __('Add Email'); ?></legend>
<?php
echo $this->Form->input('subject');
echo $this->Form->input('email_text');
echo $this->Form->hidden('email', array('value' => $this->params['named']['contact_email']));
echo $this->Form->hidden('user_from', array('value' => $this->Session->read('User.id')));
echo $this->Form->hidden('created', array('value' => date("Y-m-d")));
echo $this->Form->hidden('modified', array('value' => date("Y-m-d")));
echo $this->Form->hidden('model', array('value' => $this->params['named']['model']));
?>
</fieldset>
<?php echo $this->Form->end(__('Submit', true));?>
</div>
The real issue -- where to redirect?
$this->redirect(array('controller' => $this->data['Email']['model'], 'action' => 'view', $this->data['model']['id']));
After implementing answer one, I get these errors on redirect (email saves and sends successfully though, so its just redirect issue).

Answer 1

What I would suggest, is to build a full return URI using:
$this->params['controller']
$this->params['action'];
$this->params['pass'];
So it would look something like this:
$returnUrl = $this->params['controller'] . '/' . $this->params['action'] . '/' . implode('/', $this->params['pass']);
// let's also replace the slashes with, say, underscores
$returnUrl = str_replace('/', '_', $returnUrl);
echo $this->Html->link('Email', array('controller' => 'emails', 'action' => 'add', 'contact_email' => $model, 'returnUrl' => $returnUrl), array('class' => 'button add'));
in add.ctp
echo $this->Form->hidden('returnUrl', array('value' => $this->params['named']['returnUrl']));
and in email's controller
$this->redirect('/' . str_replace('_', '/', $this->data['Email']['returnUrl']));

Answer 2

$this->redirect($this->referer(array('action' => 'index')));
where index is your default action if the referring link doesn't exist.
read up here
e.g your user is on content/view/my-content, he clicks emails/add, fills in his details, submits. the referring page is content/view/my-content, so he (should) be redirected back there.

I added this to app_controller.php:
public function sendEmail($to,$from,$subject,$body,$headers=array(),$save_to_db=true)
{
if($save_to_db == true)
{
//do model crap here
$this->Email->create();
$data = array(
'email' => $to,
'subject' => $subject,
'email_text' => $body,
'user_from' => $from,
// map fields here
);
if($this->Email->save($data) == false)
{
$this->log("Email to '$to' from '$from' with subject '$subject' failed to save into the database!");
}
} // end save to db
$email = new EmailComponent();
//$email->startup($this);
//reeset email component
$email->reset();
/* SMTP Options */
$email->smtpOptions = array(
'port'=>'25',
'timeout'=>'30',
'host' => 'smtp.gmail.com',
'username'=>'###########',
'password'=>'###########',
);
/* Set delivery method */
//$email->delivery = 'smtp';
$email->from = $from;
$email->to = $to;
$email->subject = $subject;
$email->replyTo = $from;
$email->from = '############ <' . $subject . '>';
$email->sendAs = 'html'; //Send as 'html', 'text' or 'both' (default is 'text')
$success = $email->send($this->data['Email']['email_text']);
if($success == false)
{
$this->log("Email to '$to' from '$from' with subject '$subject' failed to send!");
}
return true;
} // end sendEmail
And then called the function after setting variables in my emails controller. (e.g. the $to, $from, $subject, $body, $headers)
