Action hook 'load-{$page_hook}'

Description

Fires before a particular screen is loaded. The load-* hook fires in a number of contexts. This hook is for plugin screens where a callback is provided when the screen is registered. The dynamic portion of the hook name, `$page_hook`, refers to a mixture of plugin page information including: 1. The page type. If the plugin page is registered as a submenu page, such as for Settings, the page type would be 'settings'. Otherwise the type is 'toplevel'. 2. A separator of '_page_'. 3. The plugin basename minus the file extension. Together, the three parts form the `$page_hook`. Citing the example above, the hook name used would be 'load-settings_page_pluginbasename'.
