Filelist Form Field

The filelist form field type provides a drop down list of files from a specified directory. If the field has a saved value this is selected when the page is first loaded. If not, the default value (if any) is selected.

By default, the first item on the list is '- None Selected -' (which is translatable) and is given the value '-1' and this is followed by '- Use Default -' (also translatable) given the value '0'.

  • type (mandatory) must be filelist.
  • name (mandatory) is the unique name of the field.
  • label (mandatory) (translatable) is the field html label.
  • description (optional) (translatable) is the field description.
  • directory (optional) is the filesystem path to the directory containing the files to be listed. If omitted the directory given by JPATH_ROOT is assumed.
  • default (optional) is the default file name.
  • filter (Joomla 3.x) or fileFilter (Joomla 4.0 and later) (optional) is a regular expression string which is used to filter the list of files selected for inclusion in the drop-down list. If omitted, all files in the directory are included. The filter argument expression is applied before the exclude argument expression. For information on constructing regular expressions see Regular expressions in parameter arguments.
  • exclude (optional) is a regular expression string which is used to exclude files from the list. The exclude argument expression is applied after the filter argument expression. For information on constructing regular expressions see Regular expressions in parameter arguments.
  • stripext (optional) is a Boolean argument. If true then file name extensions will be stripped from the file names listed. Also note that the file name will be saved without the extension too.
  • hide_none (optional) is a Boolean argument. If true, the '- None Selected -' item is omitted from the drop-down list.
  • hide_default (optional) is a Boolean argument. If true, the '- Use Default -' item is omitted from the drop-down list.
