[Cannot Modify Header Information Error]

Here is line 218: public function actionRedirectSomewhere($itemId) {$this->redirect(array('items/index'));}

 

It's the function call with the redirect statement. You were right. I was getting this error because I omitted the closing php tag at the end of the ItemsController. I was told I should do that  (omitting closing php tags) but did not understand when, why and where I should omit this ?> if at all.

[Cannot Modify Header Information Error]

When a user clicks a button in my application, it is supposed to reroute them to a certain page in my application, but instead I get the following error message: 

 

Cannot modify header information - headers already sent by (output started at /home/colly/public_html/myapp/ItemsController.php:218)

 

and here is the function inside of the itemsController that generates the error:

public function actionRedirectSomewhere($itemId) {$this->redirect(array('items/index'));}

 

It still gives me the same error if I call the function without the parameter like this: 

actionRedirectSomewhere() {$this->redirect(array('items/index'));}

 

I am not aware of any headers that I am sending.

 

How can I fix this error?

Any help would be appreciated.

[Controller Parameters]

Thanks, I understand now.

[Controller Parameters]

Thanks, that answered my question. Just out of curiosity, why wouldn't I want to be that generic with my parameter names. With some other frameworks, I could just write a function with parameters without any change to a config file and they work. Why would you recommend not having that feature here?

[Controller Parameters]

How do I do that? Is there any way to make it so that any controller action with a parameter will work with this URL format:

controller/action/parameter

[Controller Parameters]

When I create this method actionTest($parameter){

                                                            print($parameter);

                                                            }

inside of a controller and attempt to access it in the browser I get an error 400.

 

How can I set up yii so that if I enter:

/controller/test/text  it would simply print the string 'text' on the screen instead of returning an invalid request error?

 

I already verified that the URL is correct. If I write actionTest(){  print('text'); } and then go to /controller/test/text then it works just fine. 

 

How can I set up yii so that a controller action can accept parameter values in the URL?
