Cacher is the code snippet organizer for pro developers

/*
  The idea is to populate a (multi-)select list with a list of resources, 
  returning the id(s) in templates, snippetrs and chunks.
  
  This approach is much more flexible as the one offered by the resource TV.

  Important: This is not a snippet or a plugin. Use @EVEL or @SELECT code as input value for a TV.
*/

/* Example 1 
  Return a simple list with pagetitles filtered by parent and id and ordered by menuindex:
*/

  @SELECT pagetitle, id FROM [[+PREFIX]]site_content WHERE (parent=899 AND id<>1058) ORDER BY menuindex

/* Example 2a
  Add the resource id behind the pagetitle 
  
  This one is using @EVAL and getResources.

  /* Much shorter: */
  
/* Example 3
   Create resource list filtered by a Tv value and a template id using JOIN.
