Hooks Generator

Pick a hook and get a callback with the right signature — the parameter count, the priority and, for filters, the return value that stops you white-screening the site.

The hook

Hook name

KindKnown core hook — signature filled in below

Filters the post content before it is displayed. Runs on every post render, so keep it cheap.

Callback

Function name

Priority

The default. Runs in registration order alongside other tens.

Accepted args

Style

Parameters1 passed to the callback

BodyModify the value, then let the generator return it.

return $content; is appended automatically — a filter that returns nothing wipes the value.

Extras

Include the remove_ call

Adds a commented remove_action/remove_filter with the matching priority.

Skip in the admin

Adds an is_admin() early return so the callback only runs on the front end.

Paste into a plugin, an mu-plugin, or a functionality plugin.
