index_rel_link filter
To use index_rel_link 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_index_rel_link_defaults and we registered using add_filter. The first parameter index_rel_link is name of the hook, The second parameter modify_index_rel_link_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 index_rel_link filter.
Parameters
- No parameters
Live Example
apply_filters( 'index_rel_link' )
Below is an example how you can use this hook.
function modify_index_rel_link_defaults() {
// Update the $path variable according to your website requirements and return this variable. You can modify the $path variable conditionally too if you want.
return $path;
}
// add the filter
add_filter( "index_rel_link", "modify_index_rel_link_defaults");
To remove a hook callback, use the example below.
remove_filter( "index_rel_link", "modify_index_rel_link_defaults");
Please make sure provide the same callback function name, priority and number of arguments while removing the hook callback.
