Simple Hook Widget

This widget allows the user to insert a hook, with a name of their choosing, in any sidebar.

The hook can be anything, an existing hook from the WordPress Core, a plugin, a theme, or something you’ve come up with on the fly. Once the hook exists, your plugins, your theme, or the WordPress Core to make something happen with that hook.

This can be used in conjunction with other more complex plugins, to allow you to trigger a hook from the sidebar (yes, that is intentionally vague). It can also serve as a quick alternative to making very simple widgets tied to code from a theme. Say you have a chunk of code which already exists on your site, you’d like to also have it placed in a sidebar, but don’t want to make a widget out of it (since its entirely theme-centric). You could simply hook this chunk of code to a custom hook and use the Simple Hook Widget to place that custom hook in the sidebar.

This is clearly not the best method of widget development, but there may be times where such on option is useful to a developer in a pinch.

Update 2.0

• New filter which allows developers to specify what hooks are available to choose from.

Warning: Use this plugin with care. If you are not a developer and don’t know what ‘hooks’ are, this plugin is not for you. This plugin will allow you to enter ANY hook, and will run it in the sidebar – that includes core WordPress loaded with actions that could result in problems for your site.

Developer Notes

IMPORTANT:

If the ‘simple-hook-list’ is not filtered, the Simple Hook Widget will not show a drop down in the widget interface, but instead it will provide an empty text field allowing a user to enter ANY hook they like.

Using the hooks

Here is a simple example of how to use a hook used in the Simple Hook Widget. Its just like using any other hook in WordPress. Remember, you can do whatever you want here, you just need to make sure the hook used in the add_action() is the same as the hook name selected in a particular widget.

Example #1:

function simple_hook_super_example() { echo "This is my super simple hook widget"; } add_action('example-hook-name-one', 'simple_hook_super_example'); You can create any number of different widgets by simply writing a function, and adding it as an action to a hook. Here is a similar one as the first, but this is here to illustrate the point. Example #2:

function simple_hook_awesome_example() {
