Plugin Description
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() {
//Do whatever you want your 'widget' to do, when the 'example-hook-name-two' hook is chosen.
echo "This is my awesome simple hook widget";
}
add_action(‘example-hook-name-two’, ‘simple_hook_awesome_example’);
Creating dropdown of Pre-determined hooks
Filter: ‘simple-hook-list’
Version 2.0 of the Simple Hook Widget includes the 'simple-hook-list' filter which allows developers to specify a set of hooks which can be selected from the widgets admin panel.
The function you create should return an associative array where the index is the actual hook's name, and the value is the text that will represent it in the drop down on the widgets panel.
Example:
function simple_hook_example_filter($hooks){
$hooks = array (
‘example-hook-name-one’ => ‘Awesome Widget’,
‘example-hook-name-two’ => ‘Simple Widget’
);
return $hooks;
}
add_filter(‘simple-hook-list’, ‘simple_hook_example_filter’);
IMPORTANT:
If the ‘simple-hook-list’ is not filtered, the Simple Hook Widget will not show a drop down in the widget interface, but instead it will provide an empty text field allowing a user to enter ANY hook they like.
Hook: simple-hook-default
This hook allows developers provide a default value for the Simple Hook widget. By default, the default value for the hook, is an empty string.
Example:
function simple_hook_example_default($default_hook){
return ‘example-hook-name-two’;
}
`
Note: If filtering ‘simple-hook-list’ to create a drop down, the default value must match one of the keys in the array passed to the filter – otherwise this default will do nothing.
Hook: simplehookupdate_
This widget also contains an internal hook, which will be your hook, prefixed with simplehookupdate_. So if you use this plugin to create a hook name ‘testhook’, the widget, aside from creating the ‘testhook’ in the chosen sidebar location, will also create a hook called ‘simplehookupdate_testhook’. This hook occurs within the update method of the WP_Widget class, immediately before $instance is returned.
Not sure how useful this is, but a friend suggested it, so here is it.
