Hi @ all !
I’m trying to set a parameter to an action in my controller and get it via GET
example:
localhost/default/my_action/name/foobar
Then I’m trying to use name/foobar as params of my action like this:
public function actionmy_action($name) {
echo $name;
}
Here I expect a page that says ‘foobar’ but i get :
Missing argument 1 for defaultController::actionMy_action(), called in C:\wamp\framework\web\actions etc....
How I can solve this ?
Do not pass parameters to actions. just access $_GET[‘arrayIndex’] in your actions…
You should also specify url rules to maths the url u desire. eg:
'index/<name:\w+>'=>array('site/index')
and you enter the app though domain.tld/index/MyName
The value MyName is available in your actions etc… through $_GET[‘name’]
I m trying to do a multi-step form.
this is why i need to relaunch my controller action with a defined step as parameter if an error occurs.
example:
public function actionmy_action($step) {
switch ($step):
case 1:
//(the first step of my form)
case 2:
//(the 2nd step of my form)
if ($model->hasErrors()) #if an error is found here
{
// back to step 1
$this->actionmy_action(1);
}
endswitch;
I think there is a bug from the PHP interpreter because it gets a syntax error with :
public function actionmy_action($_GET['step']=1) {}
result:
Parse error: parse error, expecting `')'' in C:\wamp\www etc....
you still do not pass a parameter to your action. redirect to the step you desire with
$this->redirect(array('controller/action','step'=>'stepNumber'));
from your action.
It is not a part of the convention of Yii to pass values to your actions through parameters.
Ok man,
I asked for this because I wanted to avoid using of redirect(), because this sends new redirection headers so the browser will have to reask for a new ‘controller/action/step’ (HTTP GET /controller/action/step )
Refer the sample in Yii manual
http://www.yiiframework.com/doc/guide/form.action
You can see how to access the GET or POST variable in action method.
Well, instead of using a redirect, you can create the form’s action attribute to have the proper $_GET items
<form action="<?php echo $this->createUrl(array('controller/action','step'=>'stepNumber')); ?>" method="post">
... inputs ...
</form>
Then you can structure your action like this:
public function actionMy_Action()
{
$step = (isset($_GET['step']) ? $_GET['step'] : 1);
switch ($step)
{
....
}
}
This syntax:
public function actionmy_action($_GET['step']=1) {}
is wrong. Firstly, with Yii action functions do not have parameters passed to them. Secondly, you should not (and cannot) assign default values to super global variables like this.
Thanks,
but I already made a similar scenario :
$s = Yii::app()->request->getQuery('step',1);
switch($s):
case 1:
$this->render('step1',array('model'=>$model);
break;
case 2:
// etc....
break;
endswitch;
