[pmwiki-users] foxfilter: define ptvfmt

[noskule]

hi hans
Is is some how possible to define the ptvfmt for a given field/ptv 
inside a foxfilter function?

In this function I get the ptv "Category" with category names, "Cat1 
Cat2", add linkbrackets and want to save it as ptvfmt=text

thanks
nos


$FoxFilterFunctions['FoxCategories'] = 'FoxCategoriesFilter';
function FoxCategoriesFilter($pagename, $fields) {
  global $CategoryGroup;
  $categories_string = trim( $fields['ptv_Categories'] );
  if ( $categories_string != "" ) {
    $categories_arr = explode(" ",$categories_string);
    for($i=0;$i<count($categories_arr);$i++) {
      $out = $out."[[$CategoryGroup/".$categories_arr[$i]."]] ";
      }
    }
  $fields['ptv_categories_links'] = $out;
  return $fields;
  }
