Chevrons Code

PHP, ASP.net, HTML, JavaScript, Yii and MySQL

This extension is use to validate the field is required or not required depends by another field.

For Example, now the form have 2 fields, they are Name and Email. You can set if Name was not empty then Email field will become required to force the user enter the value.

In the Model rules you just include the extension file and then set the if value for which object only.

array('email', 'ext.requiredif', 'if' => 'name')

I had install Rights module inside my application. The Rights module itself wouldn’t auto integrate with the controller.

So I need to integrate myself, at each of the controller we need to add 2 extra function they are:

public function filters() {
  return array(
    'accessControl', 
  );
}

and

public function accessRules() {
  return array(
    array('allow',
          'action' => array('Index'),
          'users' => array('@'),
    ),
  );
}

Because I didn’t found any example of Yii autocomplete function. particularly showing how to fetched data via a server request.

For the widget function in view:

$this->widget('zii.widgets.jui.CJuiAutoComplete', array(
  'name' => 'username',
  'value' => $model->username,
  'sourceUrl' => array('user/getusername'),//path of the controller
  'options' => array(
    'minLength' => '1', // min chars to start search
    'select' => '' // when the value selected
  ),
));

Now, we start create the getusername action in the UserController file.

Because need develop an APi application with frontend and backend together.

Frontend without any interface and it just return JSON format to the user. But backend have interface to let user do the setting and update data.

In Yii main.php only allow set one error page. The solution is set the error page in controller class.

You can follow below example to write your own error page to each controller.

Default Yii cgridview pagination didn’t show the first and last page. But actually it was hidden but the CSS class, the easy method is change the CSS class to let it can show it.



how to do it? open pager.css file and find the code like below.

Controller error handler:

ul.yiiPager .first, ul.yiiPager .last {
    display: none;
}

Below example showing you how to add the row number in cgridview widgets.

You just need add the following script inside the array columns.

array(
	'header' => 'No.',
	'value' => '$this->grid->dataProvider->pagination->currentPage * $this->grid->dataProvider->pagination->pageSize + ($row+1)',
),

The completed example as below:

Normally we include Javascript in our application in Yii is below script

Yii::app()->getClientScript()->registerScriptFile('jquery.js');	

But, now we need include yiigridview.js script file in our application. Because it was generate by Yii and it located at assets folder. So above example cannot used.

In here, we need to call getAssetManager() to get the assets folder url and folder name generated by Yii.

Yii::app()->getAssetManager()->publish(Yii::getPathOfAlias('zii.widgets.assets'));

The above example will get the gridview path from the assets folder.

Following last post CGridview listdata with CArrayDataProvider to list down the data with cgridview.

But it just can listing the records without the pagination. Use back last post example script and then modify the CArrayDataProvider as below example.

Yii, use CArrayDataProvider to listing out the array with CGridView widgets.

Below example are showing how to use it.
Data array:

$data = array();
$data[] = array('id' => 1, 'name' => 'name 1', 'age' => 22, 'date' => '1-Jan-2013');
$data[] = array('id' => 2, 'name' => 'name 2', 'age' => 25, 'date' => '1-Feb-2013');
$data[] = array('id' => 3, 'name' => 'name 3', 'age' => 22, 'date' => '1-Mac-2013');
$data[] = array('id' => 4, 'name' => 'name 4', 'age' => 28, 'date' => '1-Jan-2013');
$data[] = array('id' => 5, 'name' => 'name 5', 'age' => 23, 'date' => '1-Apr-2013');
$data[] = array('id' => 6, 'name' => 'name 6', 'age' => 29, 'date' => '1-May-2013');
$data[] = array('id' => 7, 'name' => 'name 7', 'age' => 21, 'date' => '1-Jan-2013');
$data[] = array('id' => 8, 'name' => 'name 8', 'age' => 20, 'date' => '1-Feb-2013');

In Yii CGridView it doesn’t provide absolute row number in all the pages.

The easy way is write the a calculation method inside the column to show the column number.
