TYPO3 TCA execute hook after delete in backend - php

I want to manipulate some values and execute a custom function if an object is deleted trought the backend.
ext_localconf.php
$GLOBALS ['TYPO3_CONF_VARS']['SC_OPTIONS']['t3lib/class.t3lib_tcemain.php']['processDatamapClass'][''] = TES\TesTest\Hooks\TCEmainHook::class;
$GLOBALS ['TYPO3_CONF_VARS']['SC_OPTIONS']['t3lib/class.t3lib_tcemain.php']['processCmdmapClass'][''] = TES\TesTest\Hooks\TCEmainHook::class;
Additionally, I created the following class in my extension /Classes/Hooks/TCEmainHook.php
namespace TES\TesTest\Hooks;
use TYPO3\CMS\Core\DataHandling\DataHandler;
class TCEmainHook
{
public function processCmdmap_deleteAction($table, $id, array $recordToDelete, &$recordWasDeleted, DataHandler $dataHandler)
{
var_dump($table);
var_dump($id);
die;
}
}
I don't get what I am doing wrong. Does someone have any suggestions?

How to read config values in PHP controller?

I am using symfony 4.2 framework in which there is PHP controller with multiple actions. I have set below values in packages\config.yaml.
myDir: '/abc'
I have below controller with 2 actions as defined below.
//this works
public function uploadTestAction(Request $r_request)
{
$myDir = $r_request->request->get("myDir");
}
//this doesn't work
public function loadTestAction(Request $r_request)
{
$myDir = $r_request->request->get("myDir");
//$myDir = $r_request->query->get("myDir"); //this is also not working
}
Issue here is I am able to get the value in uploadTestAction but value is coming as null in uploadTestAction. I have tried using query as well but still not getting the correct value. Both request types are GET. What I am missing here or how can trace it ?
you should define it as parameter:
https://symfony.com/doc/current/service_container/parameters.html
final class XyController extends SymfonyController {
public function registerAction() {
$dir = $this->container->getParameter('dir');
}
}

TYPO3 v8. Override function in Core class

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.

Updating an object in a Collection

I'm using a Collection class to store objects of 'players'. Now in my Bet class I want to update the points of one of the players.. But I think I'm only updating it in once instance of my Collection. I'm not quite sure how to talk to the global collection object. Here's my code
Index.php I'm creating a new PlayerCollection and passing it to my Parser class
$app->get('/', function () use ($twig) {
try {
$players = new PlayerCollection();
$matchParser = new MatchParser($players);
$matches = new MatchCollection($matchParser->parse('../data/data.json'));
} catch(JsonException $e) {
die($e->getMessage());
}
echo $twig->render('home.html', [
'matches' => $matches->all(),
'players' => $players
]);
});
Parser Class I'm accepting the PlayerCollection in my constructor and setting the Player object in the Bet class using the following code.
The this->players->find() functionality is tested and returns the correct object from the collection
$bet = new Bet();
$bet->setPlayer($this->players->find($name));
Bet Class
class Bet {
private $player;
private $teamHome;
private $teamAway;
private $scoreHome;
private $scoreAway;
public function getPoints($scoreHome, $scoreAway)
{
if($scoreHome == $scoreAway ) {
$this->player->setPoints(100);
}
}
}
I call the function to calculate the score inside my Twig template
{{ bet.getPoints(match.getHomeScore(), match.getAwayScore()) }}
When I echo out the score of the player inside my bet class it's working.. But my PlayerCollection hasn't updated on my index.php page.
It might be my Template? The value's I want to update are already placed by twig, only later in the template I call the method to update the variables previous, but already placed
Any idea what I might be doing wrong? Thank you!
when you created your new Bet() object, you copied an existing instance of one of your player objects into your Bet object, thus not altering the original one.
code that was previously here didn't make sense, oops

Why I can't load models in modules?! [Using HMVC in codeigniter 2.1.2]

I hope someone can help me with this one before I jump off the window. I spent few hours on this one and don't know what am I doing wrong.
Basically, I've installed HMVC in CodeIgniter 2.1.2 and everything works fine, BUT for some reason I can't load models the same way I'm doing it in standard controllers. In the old codeigniter 1.7.1 I could use it simply by invoking $this->load->model('my_model') but now I can't?!
Every single time I'm trying to load model I get this error:
A PHP Error was encountered
Severity: Notice
Message: Undefined property: Special_cart::$db
Filename: core/Model.php
Line Number: 51
I have had installed it step-by-step according to the instructions. I got third_party next to modules folder. In modules I have few modules stored like this:
modules
--boxes
----controller
----models
----views
I invoke module in my code like this:
<?=modules::run('boxes/special_cart/index');?>
My module controller code looks like this:
class Special_cart extends CI_Controller
{
public function __construct()
{
parent::__construct();
}
public function index()
{
if ($this->session->userdata('cart'))
{
# get product id's and each quantity
$cart_product_list = array_count_values($this->session->userdata('cart'));
# get list of product_id
$product_list = array_keys($cart_product_list);
# get product details
$this->load->model('productmodel');
$this->load->model('stockmodel');
$cart_products = $this->productmodel->cart_get_products_details($product_list);
$final_cart_array = array();
foreach($cart_products as $cart_product){
$product_stock = $this->stockmodel->view_product_stock($cart_product["id"]);
if(empty($product_stock) || $product_stock["UNITS"]<=0)
$cart_product["UNITS"] = 0;
else{
if($cart_product_list[$cart_product["id_web"]]>$product_stock["UNITS"])
$cart_product["UNITS"] = $product_stock["UNITS"];
else{
$cart_product["UNITS"] = $cart_product_list[$cart_product["id_web"]];
}
}
$final_cart_array[] = $cart_product;
}
$refresh_cart_array = array();
foreach($final_cart_array as $cart_product){
for($i=1;$i<=$cart_product["UNITS"];$i++){
$refresh_cart_array[] = $cart_product["id_web"];
}
}
$this->load->view("special_cart",array(
'refresh_cart_array' => $refresh_cart_array,
'final_cart_array' => $final_cart_array
));
} else {
$this->load->view("special_cart",array(
'refresh_cart_array' => NULL,
'final_cart_array' => NULL
));
}
}
}
I've tried every possible solution found on internet - none of them work....
I hope you understand my problem but in case you need some further explanation please ask me. Can anyone help?
Looks like the model you're trying to load wants to connect to the db, but the database driver is not available. If you use database queries in your application, why don't you load the database driver automatically?
Just insert "database" in the "libraries" array in application/config/autoload.php file. Don't forget to insert your database credentials into application/config/database.php.
$autoload['libraries'] = array('database');
If you need database connection just in one single model, load it before trying to access database library.
$this->load->database();
Try loading the model stating the module name as follows
$this->load->model('module_name/productmodel');
Class Models extends MX_Loader{
function getUser($username){
$sql="SELECT * FROM user WHERE username = ? ";
return $this->db->query($sql,array($username))->row();
}
}
you must using extends MX_Loader because i don't know if using CI_Model the database core cant be load in Codeigniter,,,
Try to use extend MX_Controller class (not CI_Contoller like you are doing atm)
Based on what you have wrote in comment above, I figured that you tried to create new instance of DB in module (based on chrises comment).
Do it on constuctor of Special_cart
So update current construct to be like
public function __construct()
{
parent::__construct();
$this->load->database('default');
}
(I'm writing this from top of my head, so check the methods)
Now for sure db driver should be available in your models.
Regarding issue with HMVC I dont think there are any. I'm using HMVC for a while now, and I found no problems in it (working with databases)
I had the same problem and mistake. I missed to extend controllers to MX_Controller. So the solution would be to change CI_Controller to MX_Controller like this:
class Special_cart extends MX_Controller
{
public function __construct()
{
parent::__construct();
$this->load->model('productmodel');
$this->load->model('stockmodel');
}
public function index()
{
if ($this->session->userdata('cart'))
{
# get product id's and each quantity
$cart_product_list = array_count_values($this->session->userdata('cart'));
# get list of product_id
$product_list = array_keys($cart_product_list);
# get product details
$cart_products = $this->productmodel->cart_get_products_details($product_list);
$final_cart_array = array();
foreach($cart_products as $cart_product){
$product_stock = $this->stockmodel->view_product_stock($cart_product["id"]);
if(empty($product_stock) || $product_stock["UNITS"]<=0)
$cart_product["UNITS"] = 0;
else{
if($cart_product_list[$cart_product["id_web"]]>$product_stock["UNITS"])
$cart_product["UNITS"] = $product_stock["UNITS"];
else{
$cart_product["UNITS"] = $cart_product_list[$cart_product["id_web"]];
}
}
$final_cart_array[] = $cart_product;
}
$refresh_cart_array = array();
foreach($final_cart_array as $cart_product){
for($i=1;$i<=$cart_product["UNITS"];$i++){
$refresh_cart_array[] = $cart_product["id_web"];
}
}
$this->load->view("special_cart",array(
'refresh_cart_array' => $refresh_cart_array,
'final_cart_array' => $final_cart_array
));
} else {
$this->load->view("special_cart",array(
'refresh_cart_array' => NULL,
'final_cart_array' => NULL
));
}
}
}
this is also explained in the documentation
https://bitbucket.org/wiredesignz/codeigniter-modular-extensions-hmvc/
, here the quote:
Notes:
To use HMVC functionality, such as Modules::run(), controllers must
extend the MX_Controller class. To use Modular Separation only,
without HMVC, controllers will extend the CodeIgniter Controller
class. You must use PHP5 style constructors in your controllers. ie:
<?php
class Xyz extends MX_Controller
{
function __construct()
{
parent::__construct();
}
}

How does Joomla Model View Controller (MVC) work?

I am new to Joomla, I want to know how the Joomla controller passes data to the model, model to controller and controller to view. Although this might be a silly question, I really tried to find the answer. I hope I can get some help from the stackoverflow family.
The controller picks up the view variable in the url and using these determines which view needs to be used. It then sets the view to be used. The view then calls the model to fetch the data it requires and then passes this to the tmpl to be displayed.
Below is a simple setup of how this all works together:
components/com_test/controller.php
class TestController extends JController
{
// default view
function display() {
// gets the variable some_var if it was posted or passed view GET.
$var = JRequest::getVar( 'some_var' );
// sets the view to someview.html.php
$view = & $this->getView( 'someview', 'html' );
// sets the template to someview.php
$viewLayout = JRequest::getVar( 'tmpl', 'someviewtmpl' );
// assigns the right model (someview.php) to the view
if ($model = & $this->getModel( 'someview' )) $view->setModel( $model, true );
// tell the view which tmpl to use
$view->setLayout( $viewLayout );
// go off to the view and call the displaySomeView() method, also pass in $var variable
$view->displaySomeView( $var );
}
}
components/com_test/views/someview/view.html.php
class EatViewSomeView extends JView
{
function displaySomeView($var) {
// fetch the model assigned to this view by the controller
$model = $this->getModel();
// use the model to get the data we want to use on the frontend tmpl
$data = $model->getSomeInfo($var);
// assign model results to view tmpl
$this->assignRef( 'data', $data );
// call the parent class constructor in order to display the tmpl
parent::display();
}
}
components/com_test/models/someview.php
class EatModelSomeView extends JModel
{
// fetch the info from the database
function getSomeInfo($var) {
// get the database object
$db = $this->getDBO();
// run this query
$db->setQuery("
SELECT
*
FROM #__some_table
WHERE column=$var
");
// return the results as an array of objects which represent each row in the results set from mysql select
return $db->loadObjectList();
}
}
components/com_test/views/someview/tmpl/someviewtmpl.php
// loop through the results passed to us in the tmpl
foreach($this->data as $data) {
// each step here is a row and we can access the data in this row for each column by
// using $data->[col_name] where [col_name] is the name of the column you have in your db
echo $data->column_name;
}
