Content fields & content fields groups

Additional content fields is one of the most important part of the maps and classifieds sites. They allow to add some additional information to maps listings. Content fields take part in the search and sorting of listings. On "Maps Admin -> Content fields" page admin can order existing content fields by drag & drop rows in the table.

Each field type defines own behaviour and view of a content field. There are settings to hide field name, select custom field icon, set field as required, manage visibility on pages. Listings can be ordered by some content fields. Note, that you can assign fields for specific categories.

There are 5 core field types, during initial installation the system creates 5 content fields. Core fields have special destination. This is impossible to delete any of these fields. But it is possible to disable content and excerpt fields on Listings settings tab, "Enable listings tags input at the frontend" setting on General settings tab controls tags input. Listing addresses and listing categories can be disabled in listings settings. You can't edit slugs of core fields, can't order by them, can't set specific categories list, can't use in search.

About customization of content fields at the frontend. Each content field has following classes in their HTML output:

  • w2gm-field-output-block - common class
  • w2gm-field-output-block-{type name} - specific to content field type name (take from the list above)
  • w2gm-field-output-block-{ID} - specific to content field ID

The plugin can use custom template files for each content field. Content field template files place in "templates/content_fields/fields/" folder. In order to customize input and output templates - create or copy needed template file with the following name structure (take type name from the list above):

  • {type name}_output_{ID}.tpl.php - for the frontend markup
  • {type name}_input_{ID}.tpl.php - for the backend input markup

So custom template files will be used instead of native templates. Follow customization instructions.
