Pregunta nº 1

Prestashop - AuthController.php no recibe valores de entrada

Estoy intentando incluir google reCaptcha a la página de registro opc de prestashop, tengo la configuración de la casilla de verificación y está funcionando sin embargo el archivo php no está recibiendo la respuesta captcha. Permítanme aclarar. Esto es lo que he llevado a cabo hasta ahora: En mi header .tpl coloqué

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.

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

         // d("rechaed  here");      
        $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

        //Configuration::updateValue('STILOGOPOPUP_IMAGE', $winner_image['name']);

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

    return $output.$this->html;;

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?

Respuesta 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.

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

Respuesta 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".
