| add_filter( $hook_name, $callback, $priority, $accepted_args ) X-Ref |
| Adds a callback function to a filter hook. param: string $hook_name The name of the filter to add the callback to. param: callable $callback The callback to be run when the filter is applied. param: int $priority The order in which the functions associated with a particular filter param: int $accepted_args The number of arguments the function accepts. |
| resort_active_iterations( $new_priority = false, $priority_existed = false ) X-Ref |
| Handles resetting callback priority keys mid-iteration. param: false|int $new_priority Optional. The priority of the new filter being added. Default false, param: bool $priority_existed Optional. Flag for whether the priority already existed before the new |
| remove_filter( $hook_name, $callback, $priority ) X-Ref |
| Removes a callback function from a filter hook. param: string $hook_name The filter hook to which the function to be removed is hooked. param: callable|string|array $callback The callback to be removed from running when the filter is applied. param: int $priority The exact priority used when adding the original filter callback. return: bool Whether the callback existed before it was removed. |
| has_filter( $hook_name = '', $callback = false ) X-Ref |
| Checks if a specific callback has been registered for this hook. When using the `$callback` argument, this function may return a non-boolean value that evaluates to false (e.g. 0), so use the `===` operator for testing the return value. param: string $hook_name Optional. The name of the filter hook. Default empty. param: callable|string|array|false $callback Optional. The callback to check for. return: bool|int If `$callback` is omitted, returns boolean for whether the hook has |
| has_filters() X-Ref |
| Checks if any callbacks have been registered for this hook. return: bool True if callbacks have been registered for the current hook, otherwise false. |
| remove_all_filters( $priority = false ) X-Ref |
| Removes all callbacks from the current filter. param: int|false $priority Optional. The priority number to remove. Default false. |
| apply_filters( $value, $args ) X-Ref |
| Calls the callback functions that have been added to a filter hook. param: mixed $value The value to filter. param: array $args Additional parameters to pass to the callback functions. return: mixed The filtered value after all hooked functions are applied to it. |
| do_action( $args ) X-Ref |
| Calls the callback functions that have been added to an action hook. param: array $args Parameters to pass to the callback functions. |
| do_all_hook( &$args ) X-Ref |
| Processes the functions hooked into the 'all' hook. param: array $args Arguments to pass to the hook callbacks. Passed by reference. |
| current_priority() X-Ref |
| Return the current priority level of the currently running iteration of the hook. return: int|false If the hook is running, return the current priority level. |
| build_preinitialized_hooks( $filters ) X-Ref |
| Normalizes filters set up before WordPress has initialized to WP_Hook objects. The `$filters` parameter should be an array keyed by hook name, with values containing either: - A `WP_Hook` instance - An array of callbacks keyed by their priorities Examples: $filters = array( 'wp_fatal_error_handler_enabled' => array( 10 => array( array( 'accepted_args' => 0, 'function' => function() { return false; }, ), ), ), ); param: array $filters Filters to normalize. See documentation above for details. return: WP_Hook[] Array of normalized filters. |
| offsetExists( $offset ) X-Ref |
| Determines whether an offset value exists. param: mixed $offset An offset to check for. return: bool True if the offset exists, false otherwise. |
| offsetGet( $offset ) X-Ref |
| Retrieves a value at a specified offset. param: mixed $offset The offset to retrieve. return: mixed If set, the value at the specified offset, null otherwise. |
| offsetSet( $offset, $value ) X-Ref |
| Sets a value at a specified offset. param: mixed $offset The offset to assign the value to. param: mixed $value The value to set. |
| offsetUnset( $offset ) X-Ref |
| Unsets a specified offset. param: mixed $offset The offset to unset. |
| current() X-Ref |
| Returns the current element. return: array Of callbacks at current priority. |
| next() X-Ref |
| Moves forward to the next element. return: array Of callbacks at next priority. |
| key() X-Ref |
| Returns the key of the current element. return: mixed Returns current priority on success, or NULL on failure |
| valid() X-Ref |
| Checks if current position is valid. return: bool Whether the current position is valid. |
| rewind() X-Ref |
| Rewinds the Iterator to the first element. |
