get_terms_fields filter
Field lists modified using this filter will only modify the term fields returned by the function when the $fields parameter set to ‘count’ or ‘all’. In all other cases, the term fields in the results array will be determined by the $fields parameter alone.
To use get_terms_fields filter, first you have to register it using add_filter. You can write this code into functions.php of your activated theme or in a custom WordPress Plugin.
We at Flipper Code, always prefer to create a custom WordPress Plugin while using hooks so nothing breaks when you update your WordPress Theme in the future.
In the below live example, we have defined a function modify_get_terms_fields_defaults which takes 3 parameters and we registered using add_filter. The first parameter get_terms_fields is name of the hook, The second parameter modify_get_terms_fields_defaults is name of the function which need to be called, third parameter is the priority of calling the hook if same hook is used multiple times and the last parameter is the number of arguments (if any) to be passed in the registered function.
Sometime, you have to remove a registered hook so you can use remove_filter to remove get_terms_fields filter.
Parameters
- $selects : (string[]) An array of fields to select for the terms query.
- $args : (array) An array of term query arguments.
- $taxonomies : (string[]) An array of taxonomy names.
Below are the 3 parameters are required to use this hook.
Live Example
apply_filters( 'get_terms_fields', string[] $selects, array $args, string[] $taxonomies )
Below is an example how you can use this hook.
function modify_get_terms_fields_defaults($selects, $args, $taxonomies) { // Update the $selects variable according to your website requirements and return this variable. You can modify the $selects variable conditionally too if you want. return $selects; } // add the filter add_filter( "get_terms_fields", "modify_get_terms_fields_defaults", 10, 3 );
To remove a hook callback, use the example below.
remove_filter( "get_terms_fields", "modify_get_terms_fields_defaults", 10, 3 );
Please make sure provide the same callback function name, priority and number of arguments while removing the hook callback.
