I need to override the function
protected function getLanguageParameter()
{
$states = $this->getBackendUser()->uc['moduleData']['web_view']['States'];
$languages = $this->getPreviewLanguages();
$languageParameter = '';
if (isset($states['languageSelectorValue']) && isset($languages[$states['languageSelectorValue']])) {
$languageParameter = '&L=' . (int)$states['languageSelectorValue'];
}
$languageParameter = '&L=1';
return $languageParameter;
}
in the class TYPO3\CMS\Viewpage\Controller\ViewModuleController. It get called when you are open the View in the backend.
Lets say I would extend the class in my own extension. I already need a Hook that calls the function?
But how can I get that hook?
If the function has no hook yet you can try to insert it: make a patch and wait for it to become merged.
As 8 LTS already receives only 'priority bugfixes' it probably will not get merged.
The other way would be XClassing.

The name is quite bad, but I really don't know what else to call it.
I'm trying to make a extendable and modular plugin system for my website. I need to be able to access plugin php files that exist in a plugin directory and get access to their classes to call functions such as getting the html content that the plugin should show and more.
Below is a semi-pseudo code example of what I am trying to achieve, but how to actually arbitrarily load the plugins is where I am stuck (PluginLoader.php).
-Max
//BasePlugin.php
abstract class BasePlugin
{
public function displayContent()
{
print "<p>Base Plugin</p>";
}
};
//ExamplePlugin.php -> In specific plugin directory.
require('../BasePlugin.php');
class ExamplePlugin extends BasePlugin
{
public static function Instance()
{
static $inst = null;
if ($inst === null) {
$inst = new ExamplePlugin();
}
return $inst;
}
public function displayContent()
{
print "<p>Example Plugin</p>";
}
}
//PluginLoader.php
foreach($pluginFile : PluginFilesInDirectory) { // Iterate over plugin php files in plugin directory
$plugin = GetPlugin($pluginFile); // Somehow get instance of plugin.
echo plugin->displayContent();
}
I'm guessing here, but it seems to me that you need to:
get a list of the plugins in the desired directory.
include or require the plugin's class file.
create an instance of the class.
call the plugin's displayContent() method.
So, you probably want to do something like
$pluginDir = 'your/plugin/directory/' ;
$plugins = glob($pluginDir . '*.php') ;
foreach($plugins as $plugin) {
// include the plugin file
include_once($plugin) ;
// grab the class name from the plugin's file name
// this finds the last occurrence of a '/' and gets the file name without the .php
$className = substr($plugin,strrpos($plugin,'/') + 1, -4) ;
// create the instance and display your test
$aPlugin = $className::Instance() ;
$aPlugin->displayContent() ;
}
There's probably a cleaner way to do it, but that will ready your directory, get the plugins' code, and instantiate each one. How you manage/reference them afterwards depends on how your plugins register with your application.
I am attempting to override a module in Prestashop but the changes are just not appearing.
I have overridden a template file and a controller so I have added the following files:
\override\modules\blockwishlist\views\templates\front\mywishlist.tpl
\override\modules\blockwishlist\controllers\front\mywishlist.php
These are very simple changes where I add another column to a table that contains a button. When the button is clicked the controller generates a CSV file.
Any idea why these changes are just not being shown?
Note: I have turned on 'Force Compile' and turned of caching.
Edit:
Re overridding a controller is it:
class BlockWishListMyWishListModuleFrontController extends BlockWishListMyWishListModuleFrontControllerCore // extends ModuleFrontController
or
class BlockWishListMyWishListModuleFrontControllerOverride extends BlockWishListMyWishListModuleFrontController
okay, I did some code research (maybe thre is exists easiest way, not sure), so:
in code Dispatcher class we have
// Dispatch module controller for front office
case self::FC_MODULE :
$module_name = Validate::isModuleName(Tools::getValue('module')) ? Tools::getValue('module') : '';
$module = Module::getInstanceByName($module_name);
$controller_class = 'PageNotFoundController';
if (Validate::isLoadedObject($module) && $module->active) {
$controllers = Dispatcher::getControllers(_PS_MODULE_DIR_.$module_name.'/controllers/front/');
if (isset($controllers[strtolower($this->controller)])) {
include_once(_PS_MODULE_DIR_.$module_name.'/controllers/front/'.$this->controller.'.php');
$controller_class = $module_name.$this->controller.'ModuleFrontController';
}
}
$params_hook_action_dispatcher = array('controller_type' => self::FC_FRONT, 'controller_class' => $controller_class, 'is_module' => 1);
break;
where we see that controllers loaded without overrides, but from other side below in code we see hook execution:
// Loading controller
$controller = Controller::getController($controller_class);
// Execute hook dispatcher
if (isset($params_hook_action_dispatcher)) {
Hook::exec('actionDispatcher', $params_hook_action_dispatcher);
}
so one of possible solution (without overriding core class) :
how to override module and hope you have core version >= 1.6.0.11
in blockwishlist.php in install() method add
this->registerHook('actionDispatcher')
to condition with other hooks, so it will looks like ... !this->registerHook('actionDispatcher') || ... because this hook not registered by default and we can't just place module there.
create method (can't beautify code here)
public function hookActionDispatcher($params)
{
if ('blockwishlistmywishlistModuleFrontController' == $params['controller_class']) {
include_once(_PS_OVERRIDE_DIR_ . 'modules/' . $this->name . '/controllers/front/mywishlist.php');
$controller = Controller::getController('BlockWishListMyWishListModuleFrontControllerOverride');
}
}
you already have override/modules/blockwishlist/controllers/front/mywishlist.php file by this path
reinstall module.
it works!
more about overriding some behaviors in docs
Turns out that to override a module you dont place your files in:
~/overrides/module/MODULE_NAME
Instead you place it in:
~/themes/MY_THEME/modules/MODULE_NAME
Now the changes are exhibiting themselves.
Does anyone know if/when the module is auto-updated, will my changes get lost/overrwritten?
I'm trying to integrate Fotolia Api with Prestashop 1.6.0.9.
I already make module with custom tab, but I have no idea how set view from module folder for this tab. Sorry to say, but "documentation for developers" SUCKS.
I can't find any working solution.
public function install() {
if (!parent::install()
|| !$this->registerHook('backOfficeHeader')
|| !$this->registerHook('header')
) return false;
$tab = new Tab();
$tab->class_name = 'AdminFotoliaSelector';
$tab->id_parent = 0;
$tab->module = $this->name;
$tab->name[(int)(Configuration::get('PS_LANG_DEFAULT'))] = 'Fotolia Selector';
$tab->add();
return true;
}
I had big problem with make proper controller, and now I just can't load anything/ I have no idea how do this.
<?php
if (!defined('_PS_VERSION_'))
exit;
class AdminFotoliaSelectorController extends ModuleAdminController {
public $name;
public function __construct() {
$this->lang = (!isset($this->context->cookie) || !is_object($this->context->cookie)) ? intval(Configuration::get('PS_LANG_DEFAULT')) : intval($this->context->cookie->id_lang);
parent::__construct();
}
public function initContent() {
parent::initContent();
$this->renderForm();
}
public function renderForm() {
$path = _MODULE_DIR_."fotoliaselector";
$more = $this->module->display($path, 'views/templates/admin/fotoliaselector.tpl');
return $more.parent::renderForm();
}
When I try die($more) it gives me content of .tpl, anyway when I click tab in back office it's still empty.
I have debug options on, compiling on, cache off.
So just enlight me please, how am I supose to show ANYTHING there?
I think the problem is that you don't display tab's content at all.
I don't know what module->display method does, but I think you should change in initContent() method line:
$this->renderForm();
into
echo $this->renderForm();
If it won't help you should look at this documentation and try to do it without external classes - only try to use Smarty to display simple content without using Tab class or AdminFotoliaSelector
Well i know it will sounds weird but you need to take some similar modules, and read his code and will see some methods names are the same in each module.
Then copy that, install and play with some changes etc.
Imho you miss standard method getContent() form where you need to pass some data for smarty:
public function getContent()
{
global $smarty, $cookie;
......
//some code
......
$this->_html .= '<script type="text/javascript" src="'.__PS_BASE_URI__.'js/tinymce/jscripts/tiny_mce/tiny_mce.js"></script>';
$this->_html .= '<h1>My module title or stuff</h1>';
$this->_html .= $this->getMyCoolFormOrConfig();
$smarty->assign('errors', $this->errors);
$smarty->assign('message', $this->message);
$this->_html .= $this->display(__FILE__, 'name_of_tpl_file.tpl');
return $this->_html;
}
to simple add tab in BackOffice code like this:
$id_tab=Tab::getIdFromClassName('AdminPayment');
$newtab=new Tab();
$newtab->id_parent=$id_tab;
$newtab->module=$this->name;
$newtab->class_name='MyClassName'; //will be same like MyClassName.php in folder of you module where you need to create you class and extend the AdminTab and from there with function you need to echo you name module
$newtab->position=Tab::getNbTabs($id_tab)+1;
$newtab->name[$cookie->id_lang]=$this->l("Name of you stuff");
$newtab->name[Configuration::get('PS_LANG_DEFAULT')]=$this->l("Name of you stuff");
$newtab->add();
Study this file there /controllers/admin/AdminModulesController.php
and you see what methods are using in each module

I have created a custom module in Magento. Now I want to log(Debug) my module flow and processing function in Log/Debug file.
I know Mage::Log() function will do this but I want to customize its with my own log file.
So that I can view it another window.
Where should I write the Logger method so that I can access the method in all resource of Module like Module,Block,Controller and Helpers..
Please help me-
-Pravin
You can use method from /app/Mage.php
public static function log($message, $level = null, $file = '', $forceLog = false)
The 3d parameter is file, you can specify it and all log messages will be in it.
Mage::log('Some exseption', Zend_Log::ERR, 'my_module.log');
If I understand your question correctly; the best place to put such a method would be in your module's helper.
app/code/local/My/Module/Helper/Data.php:
class My_Module_Helper_Data extends Mage_Core_Helper_Data
{
public function myLog( $desc, $val, $log = 'my_module.log' ) {
return Mage::log( $desc, $val, $log );
}
}
This way you can call your own log via the module helper class:
Mage::helper('my_module')->myLog( 'A variable: ', $val );
However, I do agree with #viakondratiuk that this might not be a great idea, since it's more complicated that the default Mage::log method.
I'm using PHP 5.3's class_alias to help process my Symfony 1.4 (Doctrine) forms. I use a single action to process multiple form pages but using a switch statement to choose a Form Class to use.
public function executeEdit(sfWebRequest $request) {
switch($request->getParameter('page')) {
case 'page-1':
class_alias('MyFormPage1Form', 'FormAlias');
break;
...
}
$this->form = new FormAlias($obj);
}
This works brilliantly when browsing the website, but fails my functional tests, because when a page is loaded more than once, like so:
$browser->info('1 - Edit Form Page 1')->
get('/myforms/edit')->
with('response')->begin()->
isStatusCode(200)->
end()->
get('/myforms/edit')->
with('response')->begin()->
isStatusCode(200)->
end();
I get a 500 response to the second request, with the following error:
last request threw an uncaught exception RuntimeException: PHP sent a warning error at /.../apps/frontend/modules/.../actions/actions.class.php line 225 (Cannot redeclare class FormAlias)
This makes it very hard to test form submissions (which typically post back to themselves).
Presumably this is because Symfony's tester hasn't cleared the throughput in the same way.
Is there a way to 'unalias' or otherwise allow this sort of redeclaration?
As an alternate solution you can assign the name of the class to instantiate to a variable and new that:
public function executeEdit(sfWebRequest $request) {
$formType;
switch($request->getParameter('page')) {
case 'page-1':
$formType = 'MyFormPage1Form';
break;
...
}
$this->form = new $formType();
}
This doesn't use class_alias but keeps the instantiation in a single spot.
I do not know for sure if it is possible, but judging from the Manual, I'd say no. Once the class is aliased, there is no way to reset it or redeclare it with a different name. But then again, why do use the alias at all?
From your code I assume you are doing the aliasing in each additional case block. But if so, you can just as well simply instantiate the form in those blocks, e.g.
public function executeEdit(sfWebRequest $request) {
switch($request->getParameter('page')) {
case 'page-1':
$form = new MyFormPage1Form($obj);
break;
...
}
$this->form = $form;
}
You are hardcoding the class names into the switch/case block anyway when using class_alias. There is no advantage in using it. If you wanted to do it dynamically, you could create an array mapping from 'page' to 'className' and then simply lookup the appropriate class.
public function executeEdit(sfWebRequest $request) {
$mapping = array(
'page-1' => 'MyFormPage1Form',
// more mappings
);
$form = NULL;
$id = $request->getParameter('page');
if(array_key_exists($id, $mapping)) {
$className = $mapping[$id];
$form = new $className($obj);
}
$this->form = $form;
}
This way, you could also put the entire mapping in a config file. Or you could create FormFactory.
public function executeEdit(sfWebRequest $request) {
$this->form = FormFactory::create($request->getParameter('page'), $obj);
}
If you are using the Symfony Components DI Container, you could also get rid of the hard coded factory dependency and just use the service container to get the form. That would be the cleanest approach IMO. Basically, using class_alias just feels inappropriate here to me.
function class_alias_once($class, $alias) {
if (!class_exists($alias)) {
class_alias($class, $alias);
}
}
This doesn't solve the problem itself, but by using this function it is ensured that you don't get the error. Maybe this will suffice for your purpose.
