List of hooks for esoBB

There are plenty of hooks throughout this forum software’s code which you can hook onto your own plugins. The intention behind hooks is to provide a framework for developers wishing to add onto their forum, or extensibility. If you’re looking to create a plugin but can’t find the hook that you need, don’t hesitate to start a new conversation about it.

“Hooking” your code

The syntax to hook your own code onto one of these hooks is this:

$controller->addHook(hookName, yourFunction);

For example, to hook the function addSignatureToPostArray onto the getPost hook in the Conversation controller, the following would be used:

if ($this->eso->action == "conversation") { 
	$this->eso->controller->addHook("getPost", "addSignatureToPostArray"); 

Here is another example from the Debug plugin in which two functions are hooked onto the beforeDatabaseQuery and afterDatabaseQuery hooks:

function init()
	// Add hooks to be run before and after database queries.
	$this->eso->addHook("beforeDatabaseQuery", array($this, "startQueryTimer"));
	$this->eso->addHook("afterDatabaseQuery", array($this, "addQuery"));

	// Add a hook to the bottom of the page, where we'll output the debug information!
	$this->eso->addHook("pageEnd", array($this, "renderDebug"));

Some hooks allow a value to be returned which may halt any further processing in the context of the hook from occurring. One such example is the validateAddReply hook in the Conversation controller which will display a message identified by the return value of a hooked function (if applicable).

Note that $this is an instance of the eso controller in this next list of hooks as with the Conversation controller and so forth.
