custom page that send form and get data back from database

[[email protected]]

Hi,

 

I did a custom page (a php file, a controller and a tpl).

 

The tpl send data through a form and this data are used in the controller. 

 

I need to do a request and to look for values from database. If no result it return a mistake, and if a result it return the value of the database requested through  an array then I use this value and display them back in the tpl.

 

I did the following script but in return an error php

 

I'm a novice I know what I want to do, but I don't know exactly how to do it. 

 

Deprecated: mysql_query(): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead in /htdocs/controllers/front/AntiCounterfeitController.php on line 25

Warning: mysql_query(): No such file or directory in /htdocs/controllers/front/AntiCounterfeitController.php on line 25

Warning: mysql_query(): A link to the server could not be established in /htdocs/controllers/front/AntiCounterfeitController.php on line 25

Warning: mysql_num_rows() expects parameter 1 to be resource, boolean given in /htdocs/controllers/front/AntiCounterfeitController.php on line 26

 

And this is my controller code

<?php

/*  Create a custom page in PrestaShop without CMS - CustomPageController class
  /*  Read the detailed tutorial at https://iftakharhasan.wordpress.com/prestashop-create-a-custom-page-without-cms
 */

/*  The classname here will be the name of the controller  */

class AntiCounterfeitController extends FrontController {

    public function init() {
        $this->display_column_left = false;
        $this->display_column_right = false;
        parent::init();
    }

    public function postProcess() {
        if (Tools::isSubmit('submitcounterfeit')) {
            $serial = Tools::getValue('serial');
            $key = Tools::getValue('key');
        }
        
        if(isset($_POST['submitcounterfeit'])){
            $query = "SELECT * FROM `ps_counterfeit` WHERE `serial` = '{$serial}' AND `key` = '{$key}'";
            $result = mysql_query($query);
            if(mysql_num_rows($result)==0){
                $error = 1;
                $data = null;
            }
            elseif(mysql_num_rows($result)==1){
                $error = 0;
                $data = mysql_fetch_assoc($result);
            }
        }
    }

    public function initContent() {
        parent::initContent();
        $this->setTemplate(_PS_THEME_DIR_ . 'anti-counterfeit.tpl');
    }

}

Anykind of help will be much appreciated.

Use Db::getInstance()->executeS instead of mysql_query. The similar for other mysql_* functions.
