Check if URl get parameter exists

Question

my CMS generates some parameter like this: domain.com/group?page_n531=2

The usual code is:

if (isset($_GET["id"]))
{

}

But my CMS changes the 'id' for every page, I just want to check, if a parameter exist, I dont need the 'id'. Can you guys help me with that?

Thanks.

I'm not sure what you mean that you don't want the 'id'? And does id change to pId (for example)? — Epodax, Jun 03 '15 at 09:36
Its about the pagination from news, I want to display a special content if there is no parameter and if a parameter exists, the content wont be displayed and I need that template for several news and every news got its own id. — Lydia Maier, Jun 03 '15 at 09:38

The numeric part of the parameter is the id of the news module.

It is generated like: $id = 'page_n' . $this->id;

so your code (assuming you are in mod_newslist.html5 template) should read:

if (isset($_GET['page_n' . $this->id]))
{
    // Yeah we are on some page in the pagination.
}

If you should happen to be in template news_full.html5 or any other of the partial templates, you are out of luck, when hoping for a generic approach, as the id of the calling module is not available within there.

In this cases you will have to create different news_*.html5 templates for each list module and assign it as news template to said module. Within there you can hard code the module id then.
