Extra Fields

Extra Fields adds the ability to customize your ad form–by adding any kind of field you wish.

Install as follows:

Extra Fields supports individual field codes to use in the HTML template. See the supported field codes.

Module Description

To access the module, go to Classified Admin > Extra Fields. There you will be able to:

  1. You can add a limited number of fields. (The limit is imposed by MySQL, more info here)
  2. You can use a number of different controls for input on fields:
    • Input text box
    • Input text area
    • Drop Down List (with a set of exclusive values)
    • Checkbox (with a set of values)
    • Radio Button (with a set of exclusive value)
  3. Fields can be validated
    • Field must have data
    • Field must have valid URL
    • Field must have valid email address
    • Field must be an integer number
    • Field must be a decimal number
  4. Fields can be configured to display on any of these pages: the Show Ad, Place Ad, Edit Ad and Search Ads forms.
  5. Fields automatically appear on the Search Form.  If a field defines a set of values (like a list of car models, or colors), the list will be pre-populated with all valid values for the field in the search form.
  6. Fields can be public (visible to everyone) or private (visible to admin, but added by original poster)
  7. Fields can be hidden on some forms, shown on others (e.g. Show in Ad Detail, Hide on Search and Listing, Show on Search, Detail and Listing, etc)
  8. Fields can be assigned to categories, so you can have different data showing in different categories making each ad more relevant.
