W FMModules było dość pracowicie, ponieważ opracowywaliśmy wiele nowych wtyczek, a także aktualizowaliśmy je pod kątem funkcji Multi-store. Większość odwiedzających naszą stronę pyta nas o rozwiązania swoich problemów związanych z PrestaShop, a my z przyjemnością pomagamy im bezpłatnie. Jednak w niektórych przypadkach, gdy rozwiązanie problemów wymaga czasu, musimy odpowiednio obciążyć odwiedzających.

Ten artykuł zawiera serię pytań i odpowiedzi dotyczących PrestaShop na blogu FMM. Przejdźmy do najnowszych gorących pytań i odpowiedzi z 2016 roku.

Pytanie nr 1

Prestashop - AuthController.php is not receiving input values

I'm attempting to include google reCaptcha to prestashop's opc sign up page, I own the checkbox setup and it's operating however the php file is not getting the captcha response. Let me clarify. Here's what I've carried out so far: In my header .tpl I placed

In order-opc-new-account.tpl, I added

<div class="g-recaptcha"data-sitekey="[my_public_key]">

In my AuthController.php I added

if (Tools::isSubmit('submitAccount') OR Tools::isSubmit('submitGuestAccount')) //if statement was already present

{  

    // captcha code I added

    $reCaptchaUrl='https://www.google.com/recaptcha/api/siteverify';

    $reCaptchaSecret = '[my_secret_key]';

    $reCaptchaResponse = $_POST['g-recaptcha-response'];

    $ip = $_SERVER['REMOTE_ADDR'];

 

    $verifyCaptcha = file_get_contents($reCaptchaUrl."?secret=".$reCaptchaSecret."&response=".$reCaptchaResponse."&remoteip=".$ip);

    $captchaReply = json_decode($verifyCaptcha);

 

    if(isset($captchaReply->success) AND $captchaReply->success == true){

        $logger = newFileLogger(0);

        $logger->setFilename(_PS_ROOT_DIR_."/log/debug.log");

        $logger->logDebug("Captcha was successful: ".$reCaptchaResponse);

    } else {

        //captcha failed

        $logger = newFileLogger(0);

        $logger->setFilename(_PS_ROOT_DIR_."/log/debug.log");

        $logger->logDebug("Captcha failed: ".$reCaptchaResponse);

    }

     // ... prestashop registration code

}

I learned with the debugging messages that $reCaptchaResponse variable is actually coming empty everytime, even if the captcha has been checked. Any ideas why?

Edit: The form actually sends the data to authentication.php which has the following lines

require(dirname(__FILE__).'/config/config.inc.php');

ControllerFactory::getController('AuthController')->run();

My thinking is that this part of code forwards the form data to AuthController .php however it only forwards fields that it's been told to forward. It does not knows the new recaptcha field and doesn't forward that information to the file. Therefore I needs to find who chooses which data get's forwarded.

Answer No. 1

Make sure 

 is in the FORM element.

i think you should use postProcess instead OR another way is also possible with Init() but below example is for postProcess

        $winner_image      = $_FILES['winner_image'];
        $ticket_no         = (string) Tools::getValue('ticket_no');
        //d($ticket_no);

        if( $winner_image['name'] != "" )
        {
            //Format allowed i
            $allowed = array('image/gif', 'image/jpeg', 'image/jpg', 'image/png');

            //check allowed formats
            if( in_array($winner_image['type'], $allowed) )
            {
                $path = '../modules/addwinners/';
                $ext = pathinfo($winner_image['name'], PATHINFO_EXTENSION);

               $newfilename = round(microtime(true)) . '_'.$ticket_no;
               $this->fields_value['winner_image_name']=$newfilename.".".$ext;
               $helper->fields_value['winner_image_name'] = "";

                if( ! move_uploaded_file($winner_image['tmp_name'], $path.$newfilename.".".$ext) )
                {
                    $output .= $this->displayError( $path.$stilogo_image['name'] );
                    return $output.$this->displayForm();
                }
            }
            else
            {
                $output .= $this->displayError( $this->l('Image formated Not Supported.') );
                return $output.$this->displayForm();
            }
        }   


        //Se arrivo qui è perchè tutti i campi obbligatori sono stati riempiti quindi aggiorno i valori

      //  $output .= $this->displayConfirmation( $this->l('Impostazioni salvate') );                      
    }   

    return $output.$this->html;;

Question No. 3

Override and use front controller features in a PrestaShop module [1.6.x.x]

I need to modify and include functions to the PrestaShop Store Locator page. PrestaShop user manual isn't quite clear, and i want to know if it's possible to apply a Controller in a custom module. I want to develop a module that is able to optimizes StoreFrontController and its features without beginning with scratch. Is it achievable? Have you some information for me?

Answer No. 3

You can start by overriding front controller like

`"/modules/mymodule/override/controllers/front/StoresController.php" and in this fine add class "class StoresControllerCore extends FrontController {
public function initContent()
    {
        parent::initContent();
//here do whatever you like
}
}"

though you must know coding to proceed further.

Question No. 4

Valid Oauth redirect URLs?

I am operating a module on PrestaShop to include the login with facebook on my site but i require the Oauth URLs for my facebook app. i've heard that it's facebook that gives you those URLs but exactly where. Can anybody assist me?

Answer No. 4

You just need these urls in App to proceed with facebook logins which will be your "mydomain.com" 

Question No. 5

PrestaShop Two actions for two conditions for the same cart rule

I'm using PrestaShop 1 .6 .1

A client is inquiring to make a single voucher that makes a discounted rate of 5€ if the cart is having two items and 7€ if it has 3 items (or even more) .

I am beginner to PrestaShop development and I’ve been trying for 2 days without results.

Any specific tricks to follow? , exactly what hook should i utilize? Or maybe i should modify the core files .

Any kind of tip is much appreciated.

Thank you

Answer No. 5

Sadly PrestaShop doesn't have quantity base discount so you must edit core files to achieve this. Edit "/controllers/admin/AdminCartRulesController.php" to add field for quantity and for front edit "/controllers/front/OrderController.php".

Question no. 6: Rules for friendly URLs in PrestaShop

How can I define rules to replace these links with friendly URLs in PrestaShop, because there are broken links in the following URLs?

I want to convert this URL http://www.elektrojo.com/index.php?id_post=2&fc=module&module=nextblog&controller=nbpost to this one http://www.elektrojo.com/blog/2-second-blog

Also, these URLs to become SEO and user-friendly

http://www.elektrojo.com/index.php?fc=module&module=nextblog&controller=nblog to http://www.elektrojo.com/blog

http://www.elektrojo.com/index.php?id_collection=1&fc=module&module=nextblog&controller=nbcollection to http://www.elektrojo.com/blog/collection/1-test

http://www.elektrojo.com/index.php?year=2016&month=5&fc=module&module=nextblog&controller=nbarchive to http://www.elektrojo.com/blog/archive/2016-5

Answer no. 6: it looks like you have kept the /blog/ directory empty in the domain root. As soon as you remove the empty directory or rename it, the friendly URLs will become operational and work fine for your store.

Question no. 7: getting error while searching store by alphabetical order

When I write something in the PrestaShop search box to find products, it gives me the option to show results by alphabetical or price order. When I select a sorting order, I get an error of ‘Page Unavailable’. I think there is something wrong with the URL, because when I select display results by price, the URL appears like

buscar&search_query=game&submit_search=?orderby=price&orderway=asc&orderway=asc

whereas it needs to be                

buscar?search_query=game&submit_search=&orderby=price&orderway=asc&orderway=asc

How can I solve this issue?

Answer no. 7: such errors occur when a module has over ridded either "override/classes/Link.php" or "override/controllers/front/SearchController.php" files of your store. To solve the issue, you need to disable the overrides.

Disable the overrides by moving to Advance Parametersperformance. There, select ‘Yes’ and it will disable all the overrides. Seek guidance in the image below.

Question no. 8: Unable to display errors in PrestaShop redirection

I am developing a module that is powered by an API to help the users create an account in PrestaShop. The API is enabled with a button to call a URL that belongs to my website. this initiates a function that allows users to sign up for an account.

When all the information is correct it works well, but when could display error when a user creates an account.

I want to redirect users towards the authentication page which shows errors as well.

I gave it a try with this 

$this->context->smarty->assign('account_error', $myErrors);
Tools::redirect('index.php?controller=authentication');

The redirection works but the errors seem to be lost.

Is there a way to redirect and keep the errors ?

Thanks

Answer No. 8: Frankly, you cannot display any error after setting redirections, whereas you can utilize a controller to show errors. You can also consider using buttons that say ‘Fix Errors’ which directs users to an authorized page once they click it.

Add this to your controller 

if (empty($email))
  $this->errors[] = Tools::displayError('Email is empty.');

and in your tpl use in top
{include file="$tpl_dir./errors.tpl"}

Question no. 9: Facing problems in adding categories to new products in PrestaShop

I am facing a problem since long and unable to find an effective solution. It happens when I add new products to the database with the help of product object but unable to classify them in a category. The product adds without any problem but I fail to attach products to a category. 

$cat_ids = [];
    foreach ($value['kat_naziv'] as $cat_val) {
    $cat_ids[] = (int)$luceed->selectCategoryIds($cat_val)[$cat_val]['id_category'];
}

$product->id_category = 3;
$product->id_category_default = 3;

$product->save();

$product->addToCategories($cat_ids);

The $cat_ids is an array of integers that I got from the database whereas name is something I leave as a parameter to choose Category IDs;

My question is why the newly added products are not shown in the category I select for it? 

Answer no. 9: Once you add a new product, you can link it to categories by using the following code. 

$product->updateCategories($category_array);

where

$category_array = array("0" => "2", "1" => "3", "4" => "6"...... );

Pytania 10: Dodawanie listy produktów do mojego sklepu PrestaShop

Hi,          

I am naïve in managing PrestaShop store that’s why facing difficulty in adding a list of cloth products. I tried it with the help of two CSV files (one as a list, and the other for a combination of products), but it did not work.

For product imports, I added this

http://pvmag.ro/Fisiere-directoare/IMPORT%202%20-%20Copy.csv

and for combinations, I tried this

http://pvmag.ro/Fisiere-directoare/combinations_import.csv

How to fix the issue?

Odpowiedź nr. 10: Prawdopodobnie błąd może wynikać z braku separatorów pól. Upewnij się, że separatory pól i wartości wielokrotnych są zgodne z plikiem CVS. Przetestowaliśmy (;) jako separator pól i (,) do oddzielania wielu wartości i działało dobrze. Możesz również spróbować.
