Passing variables in PHP Zend Framework - zend-framework

Question

I think I have just been working too long and am tired. I have an application using the Zend Framework where I display a list of clubs from a database. I then want the user to be able to click the club and get the id of the club posted to another page to display more info.
Here's the clubs controller:
class ClubsController extends Zend_Controller_Action
{
public function init()
{
}
public function indexAction()
{
$this->view->assign('title', 'Clubs');
$this->view->headTitle($this->view->title, 'PREPEND');
$clubs = new Application_Model_DbTable_Clubs();
$this->view->clubs = $clubs->fetchAll();
}
}
the model:
class Application_Model_DbTable_Clubs extends Zend_Db_Table_Abstract
{
protected $_name = 'clubs';
public function getClub($id) {
$id = (int) $id;
$row = $this->fetchRow('id = ' . $id);
if (!$row) {
throw new Exception("Count not find row $id");
}
return $row->toArray();
}
}
the view:
<table>
<?php foreach($this->clubs as $clubs) : ?>
<tr>
<td><a href=''><?php echo $this->escape($clubs->club_name);?></a></td>
<td><?php echo $this->escape($clubs->rating);?></td>
</tr>
<?php endforeach; ?>
</table>
I think I am just getting confused on how its done with the zend framework..

Answer 1

in your view do this
<?php foreach ($this->clubs as $clubs) : ?>
...
<a href="<?php echo $this->url(array(
'controller' => 'club-description',
'action' => 'index',
'club_id' => $clubs->id
));?>">
...
That way you'll have the club_id param available in index action of your ClubDescription controller. You get it like this $this->getRequest()->getParam('club_id')

Answer 2

An Example:
class ClubsController extends Zend_Controller_Action
{
public function init()
{
}
public function indexAction()
{
$this->view->assign('title', 'Clubs');
$this->view->headTitle($this->view->title, 'PREPEND');
$clubs = new Application_Model_DbTable_Clubs();
$this->view->clubs = $clubs->fetchAll();
}
public function displayAction()
{
//get id param from index.phtml (view)
$id = $this->getRequest()->getParam('id');
//get model and query by $id
$clubs = new Application_Model_DbTable_Clubs();
$club = $clubs->getClub($id);
//assign data from model to view [EDIT](display.phtml)
$this->view->club = $club;
//[EDIT]for debugging and to check what is being returned, will output formatted text to display.phtml
Zend_debug::dump($club, 'Club Data');
}
}
[EDIT]display.phtml
<!-- This is where the variable passed in your action shows up, $this->view->club = $club in your action equates directly to $this->club in your display.phtml -->
<?php echo $this->club->dataColumn ?>
the view index.phtml
<table>
<?php foreach($this->clubs as $clubs) : ?>
<tr>
<!-- need to pass a full url /controller/action/param/, escape() removed for clarity -->
<!-- this method of passing a url is easy to understand -->
<td><a href='/index/display/id/<?php echo $clubs->id; ?>'><?php echo $clubs->club_name;?></a></td>
<td><?php echo $clubs->rating;?></td>
</tr>
<?php endforeach; ?>
an example view using the url() helper
<table>
<?php foreach($this->clubs as $clubs) : ?>
<tr>
<!-- need to pass a full url /controller/action/param/, escape() removed for clarity -->
<!-- The url helper is more correct and less likely to break as the application changes -->
<td><a href='<?php echo $this->url(array(
'controller' => 'index',
'action' => 'display',
'id' => $clubs->id
)); ?>'><?php echo $clubs->club_name;?></a></td>
<td><?php echo $clubs->rating;?></td>
</tr>
<?php endforeach; ?>
</table>
[EDIT]
With the way your current getClub() method in your model is built you may need to access the data using $club['data']. This can be corrected by removing the ->toArray() from the returned value.
If you haven't aleady done so you can activate error messages on screen by adding the following line to your .htaccess file SetEnv APPLICATION_ENV development.
Using the info you have supplied, make sure display.phtml lives at application\views\scripts\club-description\display.phtml(I'm pretty sure this is correct, ZF handles some camel case names in a funny way)

Answer 3

You can put the club ID into the URL that you link to as the href in the view - such as /controllername/club/12 and then fetch that information in the controller with:
$clubId = (int) $this->_getParam('club', false);
The 'false' would be a default value, if there was no parameter given. The (int) is a good practice to make sure you get a number back (or 0, if it was some other non-numeric string).
