Visual hook finder Pro

Pro · This feature is part of Snipfire Pro. Plans

"Which hook do I need to put something there?" The hook finder answers it on your real site: every action is labelled right where it fires on the page, and one click creates a snippet on it.

Turn it on

  1. Open any page of your site while logged in.
  2. Click Hooks in the WordPress admin bar. (Or add ?snipfire-hooks=1 to the page address.)
  3. Click Hide hooks to turn it off again.

Only people who can edit snippets see it (administrators, and roles with CSS/JS/HTML or full team access). Visitors' pages are never touched: nothing is recorded unless you switch it on.

In the editor, the Custom hook… location links straight to it: Find hooks on your site →.

Reading the page

Every action that fires in the page body gets a small label where it fires, coloured by who fires it: WordPress, a plugin (WooCommerce, for example) or your theme. Labels on the page in the panel shows or hides them.

The Hooks on this page panel lists them in page order, in sections:

  • On the page: actions with a position in the page.
  • In the <head>: actions in the page's <head>.
  • Before the page is output: actions that fire before any HTML, such as init and template_redirect (they have no position on the page).
  • Filters: the filters applied while building the page, and how often (applied 12× on this page).

Use the search box to find a hook by name. WordPress's internal plumbing (queries, caching, text domains, the admin bar and WooCommerce template-part hooks) is hidden until you tick Internal actions too. Minimise tucks the panel away.

Click a hook

The popover shows:

  • the file that fires it, and how often it fired (fires 3×),
  • what it passes: the real argument types seen on this page, for example Passes: WC_Product,
  • its description, for WordPress core hooks,
  • what's already attached, and at which priority: Already hooked here (4): pick a priority to go before or after them. For example, on a WooCommerce product page, woocommerce_single_product_summary has the title at 5, the price at 10 and the add-to-cart button at 30, so priority 7 puts your snippet between the title and the price,
  • Snipfire snippets here: your snippets that already run on it.

And buttons:

  • Add HTML here: opens the editor with a new HTML snippet on that hook.
  • Add PHP on this hook: opens the editor with a new PHP snippet whose add_action() callback is already written, with the arguments named.
  • Filter it with PHP (for filters): the same, with add_filter() and return.
  • Copy name and Docs (the official reference, for core hooks).

Pick the priority in the new snippet, save, reload the page: your snippet is there.

Good to know

  • The hook finder shows actions where they fire. Filters don't have a position on the page, so they're listed with their counts instead.
  • Pages are never cached while the hook finder is on.
  • It works with classic themes (tested with Storefront) and block themes (tested with Twenty Twenty-Five), and doesn't change how the page renders.
  • Hook descriptions come from WordPress's own documentation and are in English.
