How to set up a hook system for your site?

Question

CMS

At the moment, it is necessary to tie a system of hooks to a self-written site for some modules to work. I did not find a clean description of the system outside cms. Tell me how to properly implement this technology for connecting modules.

Answer 1

Try something like this:

$modules = array();
  
  function addToModule($module, $func) {
    $modules[$module][] = $func;
  }
  function getModule($module, $arguments) {
    foreach($modules[$module] as $func) $func($arguments);
  }

Add modules like this:

function one ($arguments) { include 'test.html'; }
addToModule('test', 'one');
function two ($arguments) { echo $arguments[1]->greating; }
addToModule('test', 'two');

And in the right place on the page, do this:
getModule('test', array($var1, $var2, $var3));

Answer 2

You can take my code:

It is very easy to transfer it to your project by taking the trait from core/traits/Singleton.phpand modifying the code in the method ::run(), it scans everything on the first run places where hooks can lie (in the terminology of my engine they are event triggers), if you do not need file scanning, you can delete that section altogether.
When registering a trigger, a closure is passed, so that useyou can use it to pass the necessary data there from the place of declaration.

Answer 3

Can you write at least what kind of CMS you have?
