Hi! This might seem a little dumb question but I would just like to know how to get the URL Parameter of a certain site.
For example, I have this url:

http://www.mysite.com/forum/thread-one

What i want is to get the forum AND the thread-one parameter.

Any ideas?

Thanks! :)

Hi

The first part of the URL (forum) is the URLSegment (you can get it using $this->URLSegment). The second part (thread-one) is the action. To access it use:

$action = Director::urlParam('Action');

hi! I tried it and I dump it to see if it shows a value but unfortunately, I get a NULL value :'(

var_dump(Director::urlParam('Action'));
exit();

result is NULL

In my widget controller. In this method:

function UserReviewsCommentFormStepOne() {
   $URLParams = Director::urlParam('Action');
      //$Segment = $URLParams['Action'];
      //$a = new HTTPRequest();
      
      var_dump($URLParams);
      exit();
   Session::clear('StepOneData');
$fields = new FieldSet(
new TextareaField("Pros","What did you like about this room?"),
new TextareaField("Cons","What did you not like in this room?"),
new OptionsetField("RecommendRoom",'Do you recommend this room?',array(
'Y'=>'Yes',
'N'=>'No'
),'Y'
)
);
      
$actions = new FieldSet(new FormAction('doUserReviewsCommentFormStepOne', 'next'));
$validator=new RequiredFields('Pros','Cons');
$form = new Form($this, 'doUserReviewsCommentFormStepOne', $fields, $actions);

return $form;
}

Also, I added a rule in my_config file for the thing that you said occur.
Something like this:

Director::addRules( 100, array(
   'reviews/$Action' => 'UserReviewsWidget_Controller'
));

Hmm I never heard of a Widget Controller. I always thought Widgets don't have a controller themselves.
Accessing the Action is certainly possible in a Page-Controller, can't help you with widgets though. Sorry.
Maybe somebody else can give some pointers?
