I want to make Drop down pagination in yii frame work, any sugession will be helpfull. thanks in advance.
You can use this code..
In your contrller:
public function actionAdmin(){
if (isset($_GET['pageSize'])) {
Yii::app()->user->setState('pageSize',(int)$_GET['pageSize']);
unset($_GET['pageSize']);}
$model=new Packages('search');
$model->unsetAttributes();
if(isset($_GET['Packages']))
$model->attributes=$_GET['Packages'];
$dataProvider=new CActiveDataProvider('Packages');
$this->render('admin',array('model'=>$model,'dataProvider'=>$dataProvider,
));
}
and in model search function use this
return new CActiveDataProvider(get_class($this),array(
'pagination'=>array(
'pageSize'=> Yii::app()->user->getState('pageSize',Yii::app()->params['defaultPageSize']),
),
'criteria'=>$criteria,
));
in your view use this
$pageSize=Yii::app()->user->getState('pageSize',Yii::app()->params['defaultPageSize']);
echo CHtml::dropDownList('pageSize',$pageSize,array(10=>10,20=>20,50=>50,100=>100,500=>500,1000=>1000),array('onchange'=>"$.fn.yiiGridView.update('packages-grid',{ data:{pageSize: $(this).val() }})",'empty'=>'-- Select Page Range --','style'=>'width:198px;'));
now dropdown pagination implemented in your yii project.
When creating any ajax request in yii CGridView like (pagination, filtering, ...etc) the result of request will render whole page, how can i avoid that?
I tried to use renderPartial for view but it doesn't work. if this is the solution, how can i do it?
I just need to render the table of GridView not whole page.
Please advice.
In controller:
$this->layout = false;
For me works also $this->renderPartial() in controller instead of $this->render()
if(Yii::app()->request->isAjaxRequest()) $this->renderPartial('view');
else $this->render('view');
U can create class:
class Controller extends CController {
public function beforeAction($action) {
if(Yii::app()->request->isAjaxRequest) $this->layout = false;
return parent::beforeAction($action);
}
}
Is there a way to make a CGridView Not load data on the initial rendering of the view it lives on, and instead make it load the first page with a subsequent AJAX request after the initial page load?
This is mostly for performance optimization. There is a data model that is rather slow behind that CGridView, and I would like to be able to have the page load in a snappy way, then have the data load up a few seconds later with an AJAX request.
You could modify the action as follows:
public function actionIndex() {
$dataProvider = new CActiveDataProvider('User'); // The dataprovider your grid uses
if (!$this->isAjaxRequest()) {
$dataProvider->criteria->addCondition('1 = 0'); // You could also use 0, but I think this is more clear
}
[...]
}
And then in your view in the javascript section:
$(function() { // If you are using jQuery this is executed when the page is loaded
$.fn.yiiGridView.update("{id-of-your-grid-view}");
});
Brewer Gorge was very close, and thanks to his suggested answer, it put me on the right track. This works:
// Controller, after creating $dataProvider, before calling $this->render...
if (!Yii::app()->request->isAjaxRequest) {
$dataProvider->criteria->addCondition('1 = 0');
}
// View
<script type="text/javascript">
$(window).load(function() {
$('#id-of-grid').yiiGridView('update');
});
</script>
Just write your code in controller like this:
$model= new Data('search');
$model->unsetAttributes();
if(isset($_GET['Data']))
$model->attributes = $_GET['Data'];
if (!Yii::app()->request->isAjaxRequest)
$data->id=0; //or something that sure model return empty
I am working with the Yii framework.
I have set a value in one of my cgridview filter fields using:
Here is my jQuery to assign a value to the searchfield:
$('#gridviewid').find('input[type=text],textarea,select').filter(':visible:first').val('".$_GET['value']."');
And here my PHP for calling the cgridview:
$this->widget('zii.widgets.grid.CGridView', array(
'id'=>'bills-grid',
'dataProvider'=>$dataProvider,
'filter'=>$model,
'cssFile'=>Yii::app()->baseUrl . '/css/gridview.css',
'pager'=>array(
'class'=>'AjaxList',
'maxButtonCount'=>25,
'header'=>''
),
'columns' => $dialog->columns(),
'template'=>"<div class=\"tools\">".$dialog->link()." ".CHtml::link($xcel.' Export to excel', array('ExcelAll'))."</div><br />{items}{summary}<div class=\"pager-fix\">{pager}</div>",));
The value appears in the search field and my cgridview works correctly without any issues, but I am unable to trigger the cgridview to refresh or filter. Does anyone know who to trigger the cgridview to filter after page load with a predefined value?
Any help would be greatly appreciated and please let me know if you need additional information.
Thank you.
You can solve the problem without any clientside code modification. In your controller action just set the default value for the attribute as shown below
public function actionAdmin()
{
$model = new Bills();
$model->unsetAttributes();
$model->attribute_name="default filter value";//where attribute_name is the attribute for which you want the default value in the filter search field
if(isset($_GET['Bills'])){
$model->attributes = $_GET['Bills'];
}
$this->render('admin',array('model'=>$model));
}
Have a look at 'default' index action that gii generates:
public function actionIndex()
{
$model = new Bills();
$model->unsetAttributes();
if(isset($_GET['Bills'])){
$model->attributes = $_GET['Bills'];
}
$this->render('index',array('model'=>$model));
}
So if you add one line like: $model->attribute = 'test';, you're done. 'attribute' is of course the attribute that has to have the default filter value (in this case value is 'test') :). So your code looks like:
public function actionIndex()
{
$model = new Bills();
$model->unsetAttributes();
if(isset($_GET['Bills'])){
$model->attributes = $_GET['Bills'];
}
if(!isset($_GET['Bills']['attribute']) {
$model->attribute = 'test';
}
$this->render('index',array('model'=>$model));
}
Of course youre attribute will have a test value (in filter) set up as long as you wont type anything in its filter field. I hope that that's what you're looking for. Your filter should work as always.
Sorry for my bad english :)

You can use Yii's update:
$.fn.yiiGridView.update('bills-grid', {
type: 'GET',
url: <?php echo Yii::app()->createUrl('controller/action') ?>"?Class[attribute]=<?php echo $_GET['value'] ?>
success: function() {
$.fn.yiiGridView.update('bills-grid');
}
});
This is how i do it, just change the URL, it should be the same controller action of the gridview and change URL parameters to the structure represented in there, should be like Bills[attribute]=value.
I'm trying to add a plain text node in a zend form - the purpose is to only dispay some static text.
The problem is - im not aware of any such way to do it.
I have used 'description' but that HAS to be attached to a form element.
Is there any way to simply display some text as part of a form? Zend considers everything as a form element so I cannot just print it out.
Eg:
The following will test your ability on so and so.
.
.
.
etc...
Any thoughts?
Zend has a form note view helper (Zend_View_Helper_FormNote), which you can use to add text.
Just create a new form element (/application/forms/Element/Note.php):
class Application_Form_Element_Note extends Zend_Form_Element_Xhtml
{
public $helper = 'formNote';
}
In your form:
$note = new Application_Form_Element_Note(
'test',
array('value' => 'This is a <b>test</b>')
);
$this->addElement($note);
Adding a hidden element with non-escaped description does the thing.
$form->addElement('hidden', 'plaintext', array(
'description' => 'Hello world! Check it out',
'ignore' => true,
'decorators' => array(
array('Description', array('escape'=>false, 'tag'=>'')),
),
));
Works perfectly. It is still attached to an element, which is, however, not rendered this way.
Code taken from: http://paveldubinin.com/2011/04/7-quick-tips-on-zend-form/
There might be a better way, but I created a paragraph by using a custom form element and view helper. Seems like alot of code for something so simple. Please let me know if you've found a more simplistic way to do it.
//From your form, add the MyParagraph element
$this->addElement(new Zend_Form_Element_MyParagraph('myParagraph'));
class Zend_Form_Element_MyParagraph extends Zend_Form_Element
{
public $helper = 'myParagraph';
public function init()
{
$view = $this->getView();
}
}
class Zend_View_Helper_MyParagraph extends Zend_View_Helper_FormElement {
public function init() {
}
public function myParagraph() {
$html = '<p>hello world</p>';
return $html;
}
}
A little late but thought I'd throw it in anyway for the benefit of the community.
Aine has hit the nail on the head. FormNote is what you need if you want to use text in Zend_Form. However, you can use it without needing to extend Zend_Form_Element_Xhtml. See example below:
$text = new Zend_Form_Element_Text('myformnote');
$text->setValue("Text goes here")
->helper = 'formNote';
Note that you can use both text and html with the formNote helper.
This functionality is built into Zend via Zend_Form_Element_Note.
$note = new Zend_Form_Element_Note('forgot_password');
$note->setValue('Forgot Password?');
I faced the same problem and decided is better not to use Zend_Form at all, but to use directly view helpers (like Ruby on Rails does) and validate on the model.
This one-liner works for me:
$objectForm->addElement(new Zend_Form_Element_Note('note', array('value' => 'Hello World')));
