Re: [fw-mvc] Creating a Zend_Dojo_View_Helper

Daniel,

Thanks alot for this - its helped me get a better idea about how the Dojo integration works, plus it does exactly what I was hoping for.

Just a couple of quick questions - for tooltips to work they must be declared in a <div> ? Or is this part of my second question - which is the code is designed to work for declarative syntax only?

My next step is to use this View Helper within a Zend_Form decorator (or a Dojo_Form) pulling in the description element - does this sound reasonable?

Cheers,

Steve

Steven,

I have a working example for you. The following code will allow you to create dijit.Tooltip elements:

<?php
class My_View_Helper_Tooltip extends Zend_Dojo_View_Helper_Dijit

{
  protected $_dijit  = 'dijit.Tooltip';

  protected $_module = 'dijit.Tooltip';

  public function tooltip($id, $value = null, array $params = array(), array $attribs = array())
  {
      $attribs = $this->_prepareDijit($attribs, $params, null);

      $html = '<div' . $this->_htmlAttribs($attribs) . '>'
            . $value
            . "</div>\n";

      return $html;
  }
}

/* and in your view scripts */

<?php echo $this->tooltip('test', null, array(
  'connectId' => 'username',
  'label' => 'My Tooltip',
), array(
  'id' => 'test'
)); ?>


This is far from an ideal solution but it's a good start.

Matthew and others: Any comments on how to refactor this into something worthy?

A few concerns:

  * The div markup still needs to be created even when using
    programmatic otherwise the main dojo helper will not attach the
    params.
  * The method signature for Tooltip::tooltip can definately be
    tidied. $value makes no sense for a start
  * The client code in the view script currently requires
    $attribs['id'] to be set. This could be tidied away in the method.

Ok. Tooltip should be quite simple. Take a look at one of the current dijit implementations:

class Zend_Dojo_View_Helper_Textarea extends Zend_Dojo_View_Helper_Dijit
{
   protected $_dijit  = 'dijit.form.Textarea';

   protected $_module = 'dijit.form.Textarea';

   public function textarea($id, $value = null, array $params = array(), array $attribs = array())
   {
       ...
   }
}

So, with absolutely no pre-thought to if this will actually work, I would start out with:

class My_Dojo_View_Helper_Tooltip extends Zend_Dojo_View_Helper_Dijit
{
   protected $_dijit  = 'dijit.Tooltip';

   protected $_module = 'dijit.Tooltip';

   public function tooltip($id, $value = null, array $params = array(), array $attribs = array())
   {
       $attribs = $this->_prepareDijit($attribs, $params, null);
       /* Output div dojoType="dijit.Tooltip" markup here only if use declarative */
   }
}

I wasnt thinking of anything that ambitious - I don't really know alot about JavaScript hence my interest in ZFs Dojo implementation.

I was hoping to implement digit.tooltip, dojox.analytics - and maybe some type of carousell.

   What dijits are you looking to implement specifically?

   Take a look at Zend_Dojo_View_Helper_Dijit. This is the base
   class you will be extending from.

   A few of us are in the early states of proposing dijit.Tree,
   dojo(X) data stores and DnD components. Let us know if that
   compliments your interests.

       Hi there,

       I'm not that familiar with Dojo but would like to implement
       View Helpers for some of the other Dijits not currently
       included with ZF - however the manual doesn't really outline
       the specifics for doing so. Can anyone help me out?

       Cheers
