Question

Allright, lets say I have a User and every user hasMany EmailAddresss.

I have created the following view, to show a single user:

<h2>
    <?php echo $user['User']['username']?>
</h2>
<h3>Addresses</h3>
<table>
    <tr>
        <th>Friends</th>
    </tr>   
<?php foreach ($user['EmailAddress'] as $emailAddress): ?>
    <tr>
        <td><?php echo $emailAddress['address']; ?></td>
    </tr>
<?php endforeach; ?>
</table>

Now I want to create in this User view, an input box, that can add a new EmailAddress associated to that account. How can I do this?

Answer 1

Create a form pointing to EmailAddressController/add method

echo $this->Form->create('EmailAddress');
//hidden field to indicate which user we are adding the email address to
echo $this->Form->hidden('user_id', array('value' => $user['User']['id'])); 
echo $this->Form->input('address');
echo $this->Form->end('Add');

This PHP should create a FORM that points to your emailaddresses/add controller/action pair. In that Add action, you’ll handle the POST and add the email and redirect back to this page.
