Select the Count action hooks and filters
check box when you want to discover all the action hooks and filters that are invoked.
When tracing is active then at shutdown
a number of trace records are written summarising the action hooks and filters that have been invoked.
Information traced
Hook shortcode parameters
The hook shortcode takes 5 positional parameters:
- Hook name(s)
- Hook type: action or filter
- Number of args passed
- Number of invocations
- Attached hook function count
To find which functions are attached use Trace attached hooks functions.
Example wp_actions
The wp_actions array may include some actions invoked before action counting was initiated.
See Must-Use and Drop-In logic.
Example bw_action_counts
Example most used
The most used list only shows the hooks that are implemented. In this example we don’t see gettext
. The filter is applied many times but there aren’t any attached filter functions.
