Zend Framework Pagination

Submitted by shane on Thu, 2010-02-11 08:07

This is a way to have Zend Framework Pagination (Paginator) working so that it remembers the query across mulitiple pages. This seemed like such a simple and obvious task, but the solution is not so obvious. The trick is to test if 'isPost()' then save the query to the session variable. That way when a visitor travels to page two we have the query in the session variable. No URL tricks or other tom foolery.

/IndexController.php

    public function searchAction()
    {
        $value = $this->_request->getPost('query');
 
        // Start a session
        $session = new Zend_Session_Namespace('value');
 
        // If $value is a post then the search has just been submitted.
        if ($this->getRequest()->isPost()) {
            $session->value = $value;
        }
 
        // Get the select from Zend_DB
        $amazon = new Model_Example();
        $result = $amazon->searchExample($session->value);
 
        // Assign Paginator data to view
        $this->view->paginator = $this->_addPaginator($result);
        $this->view->query = $session->value;
        $this->_helper->viewRenderer('list');
    }
 
    private function _addPaginator($select)
    {
        $page = $this->_getParam('page', 1);
        $paginator = new Zend_Paginator(new Zend_Paginator_Adapter_DbSelect($select));
        $paginator->setItemCountPerPage(self::ItemCountPerPage)
                  ->setCurrentPageNumber($page)
                  ->setPageRange(5);
        return $paginator;
    }

/layout/scripts/layout.phtml

<div id="search"><form action="/index/search" method="POST"><input type="text" name="query" id="query" value="<?php echo $this->query; ?>"><input type="submit" name="Submit" value="Submit"></form></div>

/views/scripts/index/list.phtml

<?php if($this->paginator): ?>
<div><?php echo $this->paginationControl($this->paginator, 'Sliding', 'pagination.phtml'); ?></div>
 
<?php foreach($this->paginator as $item): ?>
<!-- list your item data -->
<?php endforeach; ?>
 
<div><?php echo $this->paginationControl($this->paginator, 'Sliding', 'pagination.phtml'); ?></div>
<?php endif; ?>

Setup PHPunit for testing Zend Framework application

Submitted by shane on Tue, 2010-02-02 01:27

This was how I set up PHPUnit with my Zend Framework application. I'm very new to testing and have never set it up before.

<

ol>

  • Need to get PHPunit installed on the Apple Mac
    Try typing this in the command line (btw I prefer iTerm over the built in terminal).
    whereis phpunit

    • I tried a few different ways to install php, I'm not sure which one eventually installed it, but.... yeah I know sounds dumb, but when you try a bunch of different ways and then it 'just starts working' you lose track which way actually fixed it. Besides it was two weeks ago, I can't remember that far back. I do know that one of the has Xdebug turned on to generate the nice reports of code coverage.

    For example.

    Shane:tests shane$ whereis phpunit
/usr/bin/phpunit
Shane:tests shane$ phpunit --version
PHPUnit 3.4.6 by Sebastian Bergmann.
 
Shane:tests shane$

  • Now setup your environment. This is the hard part, since everyone does it different. The trouble is figuring out which pieces need to go where and why.

    • Bonus
    This will create a neat little tree of your folder structure

    ls -R | grep ":$" | sed -e 's/:$//' -e 's/[^-][^\/]*\//--/g' -e 's/^/   /' -e 's/-/|/'

    So I have this structure for my application

       |-application
   |---configs
   |---controllers
   |---models
   |-----DbTable
   |---views
   |-----helpers
   |-----scripts
   |-------error
   |-------index
   |-library
   |-public
   |-tests
   |---application
   |-----controllers
   |-----models
   |---library
   |---log
   |-----report

    Notice the "test" folder with subfolders? Good.

    We now have the necessary folder, here are files

    tests/phpunit.xml

    <phpunit bootstrap="./bootstrap.php" color="true">
    <testsuite name="My Test Suite">
        <directory>./</directory>
    </testsuite>
 
    <filter>

    Sending email via Gmail

      $config = array(
      'ssl' => 'tls',
      'port' => 587,
      'auth' => 'login',
      'username' => 'youemail@gmail.com',
      'password' => 'yourpassword'

  $gmail = new Zend_Mail_Transport_Smtp('smtp.gmail.com', $config);
  $mail = new Zend_Mail();
  $mail->addTo($this->to);
  $mail->setSubject($this->subject);
  $mail->setFrom($this->from);
  $mail->setBodyText($this->body);
 
  $mail->send($gmail);

    As you can see, you need to create an object for Gmail, then create an email object, then tell the email object to use the gmail ob

    Today I learned from Zend Framework.

    Redirecting visitors to their intended URI after login

    LoginForm.php

      ...
  // Grabs the requested URI from the server and stores it in a hidden field
  $this->addElement('hidden', 'referrer', array('value' => $_SERVER['REQUEST_URI']));
  ...

    Then after you complete authentication, send them to the referring URI

      if($form->getValue('referrer'))
      $this->_redirect($form->getValue('referrer'));
  $this->_redirect('index/index');

    Tonight's programming lessons included

    • Removing Decorators (dt, dd HTML tags) from Zend_Form_Element_Hidden types. There are several Decorators by using removeDecorator
          $addressid = new Zend_Form_Element_Hidden('addressid');
    $addressid->setAttrib('id', 'form-addressid')
              ->removeDecorator('HtmlTag')

    Zend Framework Resources

    Submitted by shane on Sun, 2010-01-03 01:56

    I'll try to bring some of the recent lessons learned in Zend Framework here on the blog. The deeper I dig, I realize the framework is very well put together and powerful.

    • The official Zend Framework Manual True to PHP, Zend has a great manual with many examples, though, if you are looking for every explicit directions where to place code you may be disappointed. Since Zend is a very loosely coupled framework, they don't always assume you're using it in the Zend Application setting.
