TYPO3 add css if GET var is not empty

My goal is quite simple. If a certain GET parameter is not empty in the URL of the present page I'd like to inject some css to it.

In the example bellow I'd like to hide everything (just for example proposes) if the tx_multishop_pi1[page_section] exists in the URL.

page{
  headerData.960= TEXT
  headerData.960.data = GP:tx_multishop_pi1|page_section
  headerData.960.required = 1
  headerData.960.value(
  <style type="text/css">
  body{
    display:none !important;
  }
  </style>
  )       
}

But this isn't working. I could try [globalString = GP:tx_multishop_pi1|page_section = somehting] but I don't want that. I want to inject css if the tx_multishop_pi1[page_section] var exists (no meter its value)

this can be done by using globalString condition and if.isTrue.data

[globalString = GP:tx_multishop_pi1|page_section > 0]
    page.headerData.960 = TEXT
    page.headerData.960 {
        value (
            <style>
                body{
                   display:none !important;
                }
            </style>
        )
       if.isTrue.data = GP:tx_multishop_pi1|page_section
    }
[end]

You can use userFunc condition (on the bottom of the TSref Conditions) to perform (almost) any comparison.

The most important thing to remember is that this function must to begin with user_ prefix, there are some old docs, which doesn't mention that or gives wrong samples. Here's a sample for you (add it to localconf.php)

function user_multishopSectionExists() {
    $gp = t3lib_div::_GP('tx_multishop_pi1');
    return (is_array($gp) && array_key_exists('page_section', $gp)) ? true : false;
}

So you can use it in the TS setup field:

[userFunc = user_multishopSectionExists()]
  page.headerData.960= TEXT
  page.headerData.960.value(
    // etc...
  )
[end]

Of course it is better idea to write general matcher ie. something like:

[userFunc = user_paramExists("tx_multishop_pi1|page_section")]
