Image below shows you two dippy widgets concatenated. Dippy2 depends on Ddippy1, Dippy1 depends on user input or argument supplied. You can have one or more dippy widgets concatenated. In this case the default CSS style is white and light green.

  2. Demo Files (only for demostration)

Yii 1.1.12 jQuery

What it does ?

  1. Manage dependent models (master-detail) in a visual way, using ajax and jquery.
  2. Demo Files (only for demostration)

Dippy allows you to manage dependent values in a visual way, dippy will automatically handle your models (CComponent based, like CActiveRecord). no interface required ! no config setup required !

Let me explain using a sample data model, commonly used on ECommerce and Stock applications.

  1. An Article.
  2. An ArticleOpt , belongs to an 'Article'.
  3. An OptVal, belongs to an ArticleOpt.

You can use two (2) Dippy Widgets to manage ARTICLEOPT and OPTVAL. Easy.

[ARTICLE]
ARTICLEID	NAME
-----------------------
AAA123		BROWIES
AAA124		CAKES

[ARTICLEOPT]
ARTOPTID	ARTICLEID	NAME
-----------------------------------------
00000001	ART123		FLAVOR
00000002	ART123		PACKAGE

[OPTVAL]
OPTVALID	ARTOPTID	NAME
-------------------------------
10000000	00000001	CHOCO	(flavor)
20000000	00000001	NUTS	(flavor)
30000000	00000002	PLASTIC	(package)
40000000	00000002	BAG	(package)

For each model, manage it using a Dippy Widget.

  1. Manage dependent models (master-detail) in a visual way, using ajax and jquery.
  2. Demo Files (only for demostration)

This is a simple Dippy Widget, used to manage a single model:

![Simple Dippy] (https://bitbucket.org/christiansalazarh/dippy/downloads/dippy.png "Simple Dippy")

You can concatenate two (2) or more Dippy Widgets, each one for every dependent model.

Example Usage:

  1. Manage dependent models (master-detail) in a visual way, using ajax and jquery.
  2. Demo Files (only for demostration)

AT FIRST PLACE, if your widgets points to 'controllerName'=>'site' then put the following in 'site' controller: ~~~ public function actions() {

return array(
	'dippy'=>array('class'=>'ext.dippy.DippyAction')
); 

} ~~~

NEXT, IN YOUR VIEW:

<h1>Dippy Demo</h1>

<label>Type an article code:</label>
<input type='text' id='Article_articleid' value='AAA123'>
<!-- 
please note: DippyWidget will bind a 'change event' using jQuery for 
this input element, so when this value changes dippy refresh automatically)
-->

<div style='width: 300px; padding: 10px; border: 2px solid #aaa;
border-radius: 5px;margin-top: 10px;'>

<?php
$this->widget('ext.dippy.DippyWidget',array(
	'title'=>'Article Options',
	'id'=>'dippy1',
	'controllerName'=>'site',	 	 // read note below
	'parent'=>'Article_articleid',	 //	parent key value
	'modelName'=>'ArticleOpt',		 //	your model name
	'parentKey'=>'articleid',		 // model belongs to (attribute name)
	'attribute'=>'name',			 // the text to edit and display
	//'logid'=>'logger',			 // ref. to: <div id='logid'></div>
));

/*
  Now insert a second Dippy Widget** (note the 'parent'=>'dippy1' value) 
  this 2nd dippy widget is listening for dippy1 selection change, when a 
  selection change occurs, it will refresh and display the dependent values 
  (the OptVal whos parent is the ArtOpt model)
*/

$this->widget('ext.dippy.DippyWidget',array(
	'title'=>'Selection Values:',
	'id'=>'dippy2',
	'controllerName'=>'site',
	'parent'=>'dippy1',	// IMPORTANT! now parent is 'dippy1'
	'modelName'=>'OptVal',
	'parentKey'=>'artoptid',
	'attribute'=>'name', // the text to edit and display
));
?>

<div id='logger'></div>
</div>

jQuery UI and extra CSS.

  1. Manage dependent models (master-detail) in a visual way, using ajax and jquery.
  2. Demo Files (only for demostration)

You can associate the style passing the string 'jquery.ui' to the 'extraCss' attribute, Dippy Widget will work togheter with jQuery UI.

Also, you can pass a single class name to the 'extraCss' attribute.

onChange Event

  1. Manage dependent models (master-detail) in a visual way, using ajax and jquery.
  2. Demo Files (only for demostration)

Call a JS function whenever a Dippy selection changes. You can use the same JS function for all dippy widgets, so look for the dippyId argument to identify wich widget is making the call. The selectionId arguments is the primary key passed when dippy makes a refresh.

<?php
$this->widget('ext.dippy.DippyWidget',array(
	'title'=>'Selection Values:',
	'id'=>'dippy2',
	'controllerName'=>'site',
	'parent'=>'dippy1',
	'modelName'=>'OptVal',
	'parentKey'=>'artoptid',
	'attribute'=>'name',
	'onChange' => "function(dippyId, selectionId){ ...yourcodehere..  }",
));
?>

Example:

in the same view were dippy widget is located, insert a text field:

echo CHtml::textField('dippy2cur');

now add the onChange event handler, like this:

'onChange' => "function(wid, id){ $('#dippy2cur').val(id);  }",

makes a selection on your Dippy widget and you will observe the text field changes too. This would be usefull when validation is required on your form.

Your models:

  1. Manage dependent models (master-detail) in a visual way, using ajax and jquery.
  2. Demo Files (only for demostration)

models.ArticleOpt.php ~~~ class ArticleOpt extends CActiveRecord {

public function onBeforeValidate($event){
	$this->artoptid = sprintf("%08d",time());
	$this->name = '* New Item *';
}

... } ~~~

models.OptVal.php ~~~ class OptVal extends CActiveRecord {

public function onBeforeValidate($event){
	$this->optvalid = sprintf("%08d",time());
	$this->name = '* New Value *';
}

... } ~~~
