Member Function Documentation

executeHooks()

HookManager::executeHooks	(		$method,
			$parameters = array(),
		&	$object = '',
		&	$action = ''
	)

Execute hooks (if they were initialized) for the given method.

Parameters

string	$method	Name of method hooked ('doActions', 'printSearchForm', 'showInputField', ...)
array	$parameters	Array of parameters
Object	$object	Object to use hooks on
string	$action	Action code on calling page ('create', 'edit', 'view', 'add', 'update', 'delete'...)

Returns

mixed For 'addreplace' hooks (doActions, formConfirm, formObjectOptions, pdf_xxx,...): Return 0 if we want to keep standard actions, >0 if we want to stop/replace standard actions, <0 if KO. Things to print are returned into ->resprints and set into ->resPrint. Things to return are returned into ->results by hook and set into ->resArray for caller. For 'output' hooks (printLeftBlock, formAddObjectLine, formBuilddocOptions, ...): Return 0 if we want to keep standard actions, >0 uf we want to stop/replace standard actions (at least one > 0 and replacement will be done), <0 if KO. Things to print are returned into ->resprints and set into ->resPrint. Things to return are returned into ->results by hook and set into ->resArray for caller. All types can also return some values into an array ->results that will be finaly merged into this->resArray for caller. $this->error or this->errors are also defined by class called by this function if error.

initHooks()

HookManager::initHooks

(

$arraycontext

)

Init array $this->hooks with instantiated action controlers.

First, a hook is declared by a module by adding a constant MAIN_MODULE_MYMODULENAME_HOOKS with value 'nameofcontext1:nameofcontext2:...' into $this->const of module descriptor file. This makes $conf->hooks_modules loaded with an entry ('modulename'=>array(nameofcontext1,nameofcontext2,...)) When initHooks function is called, with initHooks(list_of_contexts), an array $this->hooks is defined with instance of controler class found into file /mymodule/class/actions_mymodule.class.php (if module has declared the context as a managed context). Then when a hook executeHooks('aMethod'...) is called, the method aMethod found into class will be executed.

Parameters

string[]

$arraycontext

Array list of searched hooks tab/features. For example: 'thirdpartycard' (for hook methods into page card thirdparty), 'thirdpartydao' (for hook methods into Societe), ...

Returns

int Always 1
