Need explanation on Maatwebsite Excel "From View" code - netbeans-8

While researching on how I can import table listing data using collection + HTML view to an excel file, I came across maatwebsite/excel package. I managed to import the excel by following the documentation. However, I am not familiar with the code syntax used by the author. On this link, the author defines a function view() as seen in the code below:
public function view(): View
{
return view('exports.invoices', [
'invoices' => Invoice::all()
]);
}
I am not familiar with view(): View syntax. Can someone direct me to a proper documentation for this? And tell me how I can resolve this in Netbeans (See screenshot below)?

Please keep in mind, the code itself is working correctly and has no issues. I am able to download the excel file as per my requirements.
Using: Laravel 5.6, PHP 7.1.17, NetBeans 8.0.2, maatwebsite/excel 3.0
Any info on this is appreciated. Thanks in advance.

In PHP 7.0 and greater, we can define the return type. For example.
function sum(): int {
// function body.
}
And same goes for:
public function view(): View
This line says that the function view() only returns the View class object.

Prestashop 1.7 How to Display data from database to tpl

i'm new on Prestashop, i have a little problem on prestashop 1.7, i just bought a module for my orders, on the page of details when i launch smarty i can see the array $order_reference with some information, but when i go to the page of my history i can't access to this information, i don't know how to add this information to access it with my page history, do i have to create a function on history controller or class with dbclass or do u have any others solutions to add my details information of my order ?
The problem is my information is in a another table who call eo_orderreference and i can't access to it with my orders object. I think i need to write a function but as i see on internet it is wrong to write it on a tpl file, i have to do it on my class but i don't know how.
This is the information i want to add
SELECT 'order_reference' FROM eo_orderreference
Sorry i can't upload image because it contains sensible informations.
Thank for your time.
Smarty templates are meant to display data,
you should perform your query in the PHP file that recall your TPL and then use the Prestashop
assign()
method to return data to your TPL as smarty variables that you can show at front office.
See here for more details.
you can create the sql query within a function either within a module or a controller.
For example:
public function getAccessories($id_product)
{
// Your code
}
into a hook or initcontent, you can call the function on the query sql and assign it a template:
public function hookDiplayAccessoryExtraProduct($params)
{
$accessories = $this->getAccessories((int)$params['id_product']);
$this->context->smarty->assign(array(
'accessories_custom' => $accessories,
)
);
return $this->display(__FILE__, 'views/templates/front/accessory.tpl');
}

Laravel scope not responding

I am using laravel for my backend api.
My question is about an scopefilter, the problem is that it is not responding when I call to it.
I have a lot of examples for using scopefilters.
So I looked at each of them to see if I did something wrong.
But I can't seem to find the problem.
When I call to this model in laravel, I use a parameter to define too the scopefilter to use a specific function.
The point only is that it never gets to this function, I don't get a response when I have put a log in this function.
I assume it is a syntax problem but maybe someone else can find the problem for this.
public static $scopeFilters = [
"supplierArticleClientId" => "bySupplierArticleClientId"
];
public function scopeBySupplierArticleClientId($query, $clientId) {
\Log::info([$clientId]);
}
In this case I expect that I see an clientId in my log.

Prestashop 1.6 Create Module to Display Carrier Filter

My Prestashop-based site is currently having an override for AdminOrdersController.php, I have placed it in override folder.
From the link provided below, it is perfectly working fine to add a Carrier filter which is not available in Prestashop 1.6 now. I have tried the solution and it is working perfectly.
Reference: Adding carrier filter in Orders page.
Unfortunately, for production site, I have no access to core files and unable to implement as such. Thus, I will need to create a custom module. Do take note that I already have an override in place for AdminOrdersController.php. I would like to tap on this override and insert the filter.
I have managed to create a module and tried placing an override (with the code provided in the URL) in mymodule/override/controller/admin/AdminOrdersController.php with the carrier filter feature.
There has been no changes/effect, I am baffled. Do I need to generate or copy any .tpl file?
Any guidance is greatly appreciated.
Thank you.
While the answer in the linked question works fine the same thing can be achieved with a module alone (no overrides needed).
Admin controllers have a hook for list fields modifications. There are two with the same name however they have different data in their params array.
actionControllernameListingFieldsModifier executes before a filter is applied to list.
actionControllernameListingFieldsModifier executes before data is pulled from DB and list is rendered.
So you can add fields to existing controller list definition like this in your module file:
public function hookActionAdminOrdersListingFieldsModifier($params) {
if (isset($params['select'])) {
$params['select'] .= ', cr.name';
$params['join'] .= ' LEFT JOIN `'._DB_PREFIX_.'carrier` cr ON (cr.`id_carrier` = a.`id_carrier`)';
}
$params['fields']['carrier'] = array(
'title' => $this->l('Carrier'),
'align' => 'text-center',
'filter_key' => 'cr!name'
);
}
Because array data is being passed into $params array by reference you can modify them in your hook and changes persist back to controller. This will append carrier column at the end of list.
It is prestashop best practice to try and solve problems through module hooks and only if there is really no way to do it with hooks, then do it with overrides.
Did you delete /cache/class_index.php ? You have to if you want your override to take effect.
If it still does not work, maybe you can process with the hook called in the AdminOrderControllers method with your new module.

Automatically add a voucher code if the URL conains a KeyWord in Prestashop

The main goal that I want to achieve is to add a voucher code if the user has clicked on a specific external link that point to my shop.
So the (javascript?) script will analyze the url and if it contains any selected keyword will add the voucher.
Anyone knows how to do that?
Thanks
I found a pretty simple solution.
I made a module.
You can find it here: GITHUB
Was pretty easy:
Generated a basic module HERE
Selected Header Hook for my new module
Modified the header hook function in the modulename.php file in root with this one:
public function hookHeader()
{
$this->context->controller->addJS($this->_path.'/views/js/front.js');
$this->context->controller->addCSS($this->_path.'/views/css/front.css');
if (Tools::getValue('voucher')){
$cartVoucher = Tools::getValue('voucher');
$idDiscount = Discount::getIdByName($cartVoucher);
Context::getContext()->cart->addDiscount($idDiscount);
}
}
Hope will help someone.
Thanks to all.

Where to write common function or logic in laravel 4.2

I want to use a common function or logic in all controllers on laravel4.2, what would be best way to do this? Does Anyone have any idea?
You can use Helper for that.
Create helpers.php in app folder.
You can create normal function there which you can use anywhere in laravel.
Example syntax for function :
function YOUR_FUNCTON_NAME(param1,param2) {
#YOUR_CODE
}
After creating helpers.php file , add it in app/start/global.php file.
like below :
require app_path().'/helpers.php';
And you can use anywhere in your controller like this YOUR_FUNCTON_NAME(param1,param2)
Hope this help.
