I have a couple of days trying the following:

1. I have a menu with a list of items from a table (table1).

2. I have a few pages with calls to the same elements of the table from $ MANY_MANY relationship

I access the url through getURLParams () from a function in the parent page:

         public function get_url_action() {
            $full_url = $this->getURLParams();
            $url_action= $Params[Action]; 
            return new ArrayData(array("url" => $url_action));
     }

I call it with

<% control get_url_action%>
$ url
<% end_control%>

<% Control Children%>
<% Control table1%>
<% If value_table1 == get_url_action%>
I can see the data from the Children page
<% end_if%>
<% end_control%>
<% end_control%>

thank you very much, I'm a little lost.

This is a pretty good tutorial on how to use the Page Controller and urlParams to serve up customized content.

Ryan, sorry for the delay to respond, but was a little busy these days.

Thank you very much for the information, I was studying it and maybe I can integrate it into my web.

Again thank you very much!
