can i execute function with variable in template ?

18 September 2009 at 1:50am

hi
is there any way to do something like that:
class Page_Controller extends ContentController {
function abc($x) {
$doSet = DataObject::get(
$obj = '$x',
$filter = "",
$sort = "RAND()",
$join = "",
$limit = $random
);
return $doSet;
}
}
class PageOne_Controller extends Page_Controller {
}
class PageTwo_Controller extends Page_Controller {
}
ang now in template PageOne.ss return 'abc' function with 'x' like:
$abc(PageOne);
and in PageTwo.ss
$abc(PageTwo);
i had some problem with execute function in these way in templates so i ask you

You have a line $limit = $random and $random is not defined anywhere else. That should be changed eg $limit = "10".
You can also not pass variables into functions so if you are trying to do something like $abc($ClassName) this won't work.

             //marker.opis = adres;
             mapa.addOverlay(marker);

            GEvent.addListener(marker,"click",function() {
            //marker.openInfoWindowHtml(marker.opis);

$zajawka(Zajawka);

no it is not this
function replace_str($y) {
$x = str_replace("e","eee",$y);
echo $x;
}

$replace_str(aea); => aeeea
$text = "aea";
$replace_str($text) => ERROR
$replace_str(text) => teeext
but i must use this function in this way $replace_str($text)

are you using this to do some sting replace of a field of the dataobject?
if that case you can have a code like this on your controller;
function replace_str() {
$x = str_replace("e","eee",$this->y);
echo $x;
}

Make sure $this->y is the field;
then call it from the template like $replace_str

ok it works now but i cant use it in other <% control %>
OkolicaMapaPage.ss
<% control OkolicaPage %>
   $replace_str;
<% end_control %>

class OkolicaMapaPage_Controller extends Page_Controller {
   function replace_str() {
      $x = str_replace("e","eeee",$this->Title);
      echo $x;
   }
}

class Page_Controller extends ContentController {
   function OkolicaPage() {
      $obiekty = DataObject::get(
         $callerClass = 'OkolicaPage',
         $filter = '',
         $sort = '',
         $join = '',
         $limit = ''
      );
      return $obiekty;
   }
}
