Cakephp form miss communication
===

Having a problem where we are creating a form that takes a varchar, but cakephp sees the field as an int.

So how would we fix it?

Here is our add function to add a relationship.

    public function add() {
        $this->set('title_for_layout', 'Send A Relationship Request');
        $this->set('stylesheet_used', 'homestyle');
        $this->set('image_used', 'eBOXLogoHome.jpg'); 
        $this->layout='home_layout';
    
        if ($this->request->is('post')) {
    	
          $this->Relationship->set($this->request->data);
          if ($this->Relationship->validates(array('fieldList'=>array('receiver_id','Relationship.userExists'))))
    	  {
            $username=$this->Relationship->username;
    		$this->Relationship->save($this->request->data);
            $this->Session->setFlash('The relationship has been saved');  
          } else {
            $this->Session->setFlash('The relationship could not be saved. Please, try again.');
          } 
        }
      }

And here is our view (a form which asks for the username (varchar))

    <?php
    echo $this->Form->create('Relationship', array('action'=>'add'));
    echo $this->Form->input('sender_id',array('label'=>'Enter your username: '));
    echo $this->Form->input('receiver_id',array('label'=>'Username of user: '));
    echo "<br />";
    echo $this->Form->end('Click here to add relationship');
    
    ?>
