Translation of errors in form fields in PrestaShop 1.7.x

It is not possible to translate these messages because these messages are set by the browser (in the browser’s set language) and not by PrestaShop.

Fortunately, they can be rewritten, check here how to Customize the Validation Messages

Assign template vars related to page content

For example how to check if a product is in a specified category?

In Controllers -> Front -> ProductController.php


     * Assign template vars related to page content.
     * @see FrontController::initContent()
    public function initContent()
//Check if a product is in the desired category
$is_in_category = 0;
$id_category = 3;
$q = 'SELECT id_product FROM '._DB_PREFIX_.'category_product WHERE 'id_category' = $id_category AND  id_product = '.(int)$this->product->id;
$row22 = Db::getInstance()->getRow($q);            
if($row22 )   
    $is_in_category = 1;	
                'priceDisplay' => $priceDisplay,
                'productPriceWithoutReduction' => $productPriceWithoutReduction,
                'is_in_category' => $is_in_category,

            // Assign attribute groups to the template


Then in template.tpl file

{if $is_in_category == 1}

How to print an array in Smarty?


E.g Get product sizes

{foreach from=$product.size_arr item=sa name=size_arr}

or use {$product.size_arr|print_r} to dsiplay whole Array in the smarty file.

How to change “carriers -> Shipping locations and costs range” directly from database?

After a threshold was misspelled, the settings could no longer be accessed, the error occurs: the thresholds overlap.

shipping locations range

psat_range_price is the table that contains these thresholds in the database

As a solution you can change the thresholds directly in the psat_range_price database table.
