Question

The code for index.phtml as follows:

<?php foreach ($this->entries as $entry): ?>
    <?php echo $this->escape($entry->email) ?>
    <br></br>
    <?php echo $this->escape($entry->comment) ?>
<?php endforeach ?>

The code for indexAction() in IndexController:

public function indexAction()
{

    $guestbook = new Application_Model_HRModel();
    $view = new Zend_View(array('scriptPath' =>'C:/Users/398853/Documents/NetBeansProjects/PhpProject3/application/views/scripts/index'));
    $view->entries = $guestbook->fetchAll();
    echo $view->render('index.phtml');

}

The code for fetchAll() in Application_Model_HRModel:

    public function fetchAll() 
   {
       $entry = new Application_Model_HRMo();
       $resultSet = $this->getDbTable()->fetchAll();
       $entries   = array();
       foreach ($resultSet as $row) {
        $entry->setId($row->id);
        $entry->setEmail($row->email);       
        $entry->setCreated($row->created);
        $entry->setComment($row->comment);
        $entries[] = $entry;
    }

            return $entries;

}
I have 3 entries i.e. 3 rows in my databse table .
But When i request the url as http://localhost:8888/Index it says
Warning: Invalid argument supplied for foreach() in C:\Users\39885Documents\NetBeansProjects\PhpProject3\application\views\scripts\index\index.phtml on line 54 and then display last row’s entry 3 times.I think problem occurs because at first it executes index.phtml and without executing indexAction()(which further executes fetchAll()) $entries will not an array Thats Why at first it gives above stated warning. Now tell me how to start execution from indexAction() then come at index.phtml so that $entries would be an array.

In fetchAll() you use the same object, but you should create new in loop. That’s why you have 3 duplicated rows in output. About PHP warning – tru to var_dump($this->entries) and check the type
