This should work:
class IndexController extends Zend_Controller_Action
{
/**
* Homepage - display result of ajaxRequest
*/
public function indexAction()
{
}
/**
* Print result of database query
*/
public function ajaxAction()
{
// disable rendering of view and layout
$this->_helper->layout()->disableLayout();
$registry = Zend_Registry::getInstance();
$db = $registry['DB'];
// get select object to build query
$select = $db->select();
$select->from('task')->order('task_name ASC');
// echo result or what ever..
$this->view->tasks = $db->fetchAll($select);
}
}
// index.phtml (view)
<?php
echo $this->jQuery()->enable();
echo $this->jQuery()->uiEnable();
// create link to ajaxAction
$url = $this->url(array(
'controller' => 'index',
'action' => 'ajax',
));
?>
<div id="container">container</div>
<?php
echo $this->ajaxLink(
"Bring All Task", $url, array('update' => '#container')
);
?>
and in your ajax.phtml
<?php if ($this->tasks): ?>
<table>
<tr>
<th>task ID</th>
<th>task Name</th>
</tr>
<?php foreach($this->tasks as $task) : ?>
<tr>
<td><?php echo $task['task_id']; /* depending on your column names */ ?>
</td>
<td><?php echo $this->escape($task['task_name']); /* to replace " with " and so on */ ?>
</td>
</tr>
<?php endforeach; ?>
</table>
<?php else: ?>
No tasks in table.
<?php endif; ?>
regarding db you have to setup it first somewhere earlier in your code, for example front controller index.php or bootstrap.php, for example:
$db = Zend_Db::factory('Pdo_Mysql', array(
'host' => '127.0.0.1',
'username' => 'webuser',
'password' => 'xxxxxxxx',
'dbname' => 'test'
));
Zend_Registry::set('DB', $db);
