Link with confiirmation

I think we also need to add link with confirmation, especially in delete condition

CHtml::link(t("Delete"), "#", array("submit"=>array("delete","id"=>"$model->id" ),"confirm"=>"Are you sure?"));

Button with confirmation

CHtml::button('Delete', 
                array('submit' => array('user/delete','id'=>$model->usId),
                            'name'=>'btnDelete',
                            'confirm'=>'Are you sure you want to delete?',
                            'class'=>'btn btn-large btn-danger',
                            'style'=>'width:160px;'
                        ));

That's what a call clear doc

Something as clear as that, should exist for the rest.

CHtml::link, urlManager and Ajax url problems

Hi guys

I have this line in my urlManager:

'<controller:\w+>' =>'<controller>/admin', // if no action is included, then
                                           // use actionAdmin

However, when the user clicks on the CHtml::link to go to actionAdmin, then the above line causes CHtml::link to NOT include the action's name in the url in the browser's address bar.

This seems to cause problems when Ajax has to use the url.

So, if you get Ajax 404 and 'response failed' errors, start by making sure that your url contains both controller and action names.

(I'm not an Ajax expert, so if this sounds like nonsense, please let me know.)

RE: can display image link instead of text link ?

Yes.
Example:

<?php
$image = CHtml::image(Yii::app()->baseUrl.'/images/thumb-1.jpg');
echo CHtml::link($image, Yii::app()->baseUrl.'/images/image-1.jpg');
?>

For Question #13460 about default item on dropdownlist

Dear,

For selected item by dafault you need to use the next option: for example item id 78 must be the default.

array('options' => array('78'=>array('selected'=>true)))

Here you have how to use it:

<?php echo $form->dropDownList($model,'estado_id',CHtml::listData(estado::model()->findAll(),'id', 'estado'),array('options' => array('78'=>array('selected'=>true)))); ?>

Regards!

Custom Data Attributes

Does anyone knows how to add Custom Data Attributes (HTML5 data-*) to dropDownList

Country table (id, name, iso_code, calling_code)

<select name="Country[id]" id="Country_id">
<option value="">Select Country</option>
<option value="1" data-ISO="USA">United States (+1)</option>
<option value="1" data-ISO="GB">United Kingdom (+44)</option>
</select>

echo $form->dropDownList(Country::model(), 'id', 
CHtml::listData(Country::model()->findAll(), 'id','fullName'),
array('prompt' => 'Select Country', 
); 

function getFullName()
{
return $this->country_short_name.' (+'.$this->calling_code.')';
}

creating id

how can we create a id for the dropdown.

creating id

$options = array(
	'class'	=> 'singleline',
	'size'	=> '1',
	'id'	=> 'myId'
	'empty'	=> '',
	'style'	=> 'width:300px;',
);

echo $form->dropDownList($model, 'columnName', $listdata, $options);
   or
echo $form->dropDownList($name, $defaultValue, $listdata, $options);

The $name is sent to the server.
The id (part of options) is used by jquery.
