Flatboard's Hook mechanism can be confusing when you first get started, so I'll try to explain it clearly.

The hook method in the Plugin class takes two parameters: $name is the name of the hook to be executed, $param is the parameter to be passed to the hook function. It iterates through all the enabled plugins, uses the isValidHook method to determine if there is a corresponding hook function, and if so, uses the myHook method to execute the function and adds the return value to the $out variable (so that multiple plugins can use the same hook), and finally returned the $out string.

Based on incomplete testing, the order of the Hook may be related to the name of the plugin.

Example

<?php
function myPlugin_myDemoHook($param) {
    return 'Hello ' . str_shuffle($param);
}
?>

When myPlugin is enabled, it can be accessed in the main app via

$out .= Plugin::hook('myDemoHook', 'parameter');
OR
echo Plugin::hook('myDemoHook', 'parameter');

to call myDemoHook in the myPlugin.

The output may resemble:

Hello trermeapa

Very well explain to new users for never used it before. I have done 4 years of web application development so good job explaining it 😊.

Thank you for this Tillreetree@fc7e1f5a, very nicely done.
