The controller:
controllers
|-FooController.php
|-BarController.php
The views:
view
|-foo|
| |-index.php
| |-error.php
|
|-bar|
|-index.php
How to render the error.php view with an action of the bar controller?
I have tried:
$this->render('foo/error');
But it doesn't work.
try this
$this->render('//foo/error');
If you don't echo it, you will get a blank page.
The correct way is
<?=
$this->render('//foo/error');
?>
or
<?php
echo $this->render('//foo/error');
?>
This also works for Yii2

How do I change the header after login, or is using another header even the right way to do it? Meaning there would be two different headers(guest/user). I've searched for it, mostly about redirects of the entire page, not what I am looking for.
Sorry for the noob question. :/
Make two files in your view with guest_header.php and user_header.php when user is logged in user user_header.php as your header file in your layout or simply use guest_header.php
and in your column layout use it like below
when user is logged in
<?php if(Yii::app()->user->id): ?>
<?php $this->beginContent('//layouts/user_header.php'); ?>
when user is guest
<?php else: ?>
<?php $this->beginContent('//layouts/guest_header.php'); ?>
<?php endif; ?>
Added this line
<?php $this->endContent(); ?>
<?php $this->beginContent('//layouts/main'); ?>
<?php echo $content; ?>
</div><!-- content -->
<?php $this->endContent(); ?>
I am trying to display the price based on the selection of product from a drop down.
View contains:
<?php $form=$this->beginWidget('bootstrap.widgets.TbActiveForm', array(
'id'=>'plan-form',
'enableAjaxValidation'=>true,
)); ?>
<?php echo $form->dropDownListRow($model, 'plan_id',
$planList, array('id'=>'planid', 'prompt'=>'Select Plan',
'ajax' => array('type'=>'GET',
'url'=> Yii::app()->createUrl('mbr/plan/ajaxGetPrice'),
'update'=>'#price'))); ?>
<div id="price">0.00</div>
<?php $this->endWidget(); ?>
Action:
public function actionAjaxGetPrice()
{
Yii::log("Within AjaxGetPrice");
if (Yii::app()->request->isAjaxRequest)
Yii::log("ajax request");
else
Yii::log("regular request");
//$plan=Plan::model()->findByPk((int) $_GET['plan_id']);
//Yii::log(serializ($plan));
// echo $plan->price;
echo "10";
Yii::app()->end();
}
It is not updating the price. Its not calling the action at all. I looked at the suggestions found in Yiiframework and here and tried those and still no luck.
when I add this to the view
<?php
echo CHtml::ajaxLink(
"Get Price",
Yii::app()->createUrl('mbr/plan/ajaxgetprice'),
array( // ajaxOptions
'type' => 'GET',
'update' => '#price'),
array( //htmlOptions
'href' => Yii::app()->createUrl('mbr/plan/ajaxgetprice')
)
);
?>
I get the response when I click on the link, but it renders a separate page with value "10". I have URLFormat = Path.
What am I doing wrong? Any pointers?
You can also try this as shown
<?php echo CHtml::dropDownList('categories','',
$category,
array('ajax'=>array('type'=>'POST','url'=>CController::createUrl('yourController/GetId'),'update' =>'#data'))
);?>
yourController action
public function actionGetId(){
echo 10;
}
And the div
<div id="data">0.00</div>
I'm not really sure how to do this the Yii way but the following javascript should be useful.
$("#yourdropdownidhere").change(function(){
$.ajax({
url: 'your url here', //(dynamically generated by product item)
type: "get",
success: ajaxSuccessHandler
});
});
function ajaxSuccessHandler(obj) {
$('#price').html(obj);
}
I also suggest sending a JSON object as the response for AJAX requests, so it will have an actual structure. A great blog post on this to check out would be Fully ajax website with Yii
I had the same problem and solved it on the controller that renders the view. If you are using renderPartial assure that the processOutput() option is set to TRUE, otherwise Yii will not attach any Javascript.
If you use render instead of renderPartial it also works.
With YII Flashes you can do this:
Yii::app()->user->setFlash('success', "Data saved!");
However, when the flash appears on the page, it appears like so:
<div id="yw1">
<div class="alert in alert-block fade alert-info"><a class="close" data-dismiss="alert">×</a>
MESSAGE
</div>
</div>
How do I control WHERE this is placed? I don't see anything in layouts/main.php that controls this, yet they display?
They won't display anywhere unless you are calling them, a good example in the Yii default app is the site/contact view:
<?php if(Yii::app()->user->hasFlash('contact')): ?>
<div class="flash-success">
<?php echo Yii::app()->user->getFlash('contact'); ?>
</div>
<?php else: ?>
...
And the flash is set using the setFlash method
Yii::app()->user->setFlash('contact','Thank you for contacting us. We will respond to you as soon as possible.');
A possibility is that there may be a check in the Controller root class (protected/components/Controller.php), where someone may have written an init() function that checks for them. This would be called on every controller/action call so it may be there.
Another possibility is that whoever created the project edited the flash method in the framework folder (or possibly extended it), you could have a look there, it is in framework/web/auth/CWebUser.php
But as Mik said, try doing a text search in your project for getFlash or even just flash
I would do a textsearch on user->getFlashes() in your views folder. You can output the messages at any place with this
<?php
foreach(Yii::app()->user->getFlashes() as $key => $message) {
echo '<div class="flash-' . $key . '">' . $message . "</div>\n";
}
?>
You, the developer, need to display flash-messages. Yii does not do that for you.
You display them in a view, as shown by Eskimo and Mik, at a location of your own choosing . Yii could never do that, because Yii does not know the layout of your view.
hopefully a quick question here, have not been able to find out the answer on google. Anyway I have the following File upload field.
<div class="row">
<?php echo CHtml::form('', 'post', array('enctype' => 'multipart/form-data')); ?>
<?php echo $form->labelEx($model, 'doc'); ?>
<?php echo CHtml::activeFileField($model, 'doc'); ?>
<?php echo $form->error($model, 'doc'); ?>
</div>
The question I have is how to change the default text? On the page in question the upload field comes up with "No file chosen" beside the button when the page loads. I wish to change this text, anyone tell me how? Thanks.
I quick & dirty fix is this:
<?php echo CHtml::activeFileField($model, 'type',array('style'=>'width:100px;', 'onchange' => 'this.style.width = "100%";')); ?>
I would like to link to a different controller, passing in multiple parameters.

<?php echo CHtml::link('Link Text',array('controller/action',
'param1'=>'value1',
'param2'=>'value2',

<?php echo CHtml::link('Link Text',
Yii::app()->createUrl('controller/action',array(
'param1'=>'value1',
'param2'=>'value2',
'param3'=>'value3')); ?>
