Custom Query Fields



Extend your site’s querying and sorting functionality using custom field values.

The following function registers queryable fields.
register_custom_queryable_field($fieldName, $options);

Simple Example:
(The above registers the custom field ‘city’ to be searchable using query variables)
(displays posts which have a meta key ‘city’ and a value of ‘Anahiem’)

Advanced Example:
register_custom_queryable_field(“price”, array(“dataType”=>”numeric”));
(The above registers the custom field “price” to be searchable as a number using query variables)
(displays posts which have a meta key ‘price’ and a exact value of ‘500’)
(displays posts, sorted by ‘price’, which have a meta key ‘price’ and a value between ‘200’ and ‘800’)

Available Options:

  • dataType
    • text (default)
    • numeric (receive min/max query variables, see above example)
  • order
    • If the user uses the “order_by” query variable then this option determines the order. Available options are “ASC” and “DESC”(default)
  • compare
    • Compare method for text types. Defaults to ‘=’. Recommend ‘LIKE’

There is a “order_by” query var made available. This is used by adding &order_by=price to the URL. In this instance, the query would sort based on the “price” field only.

Note: This plugin does not alter any queries when in the backend.
