Hello Opencart Experts,

We are working today on Product in Opencart 4.1.0.3 and it shows error when filter product model.

Here is the screenshot https://prnt.sc/svfmIF0uBF9r

Code: Select all

$sql = "SELECT * FROM `" . DB_PREFIX . "product` `p` LEFT JOIN `" . DB_PREFIX . "product_description` `pd` ON (`p`.`product_id` = `pd`.`product_id`)";
Need to be change to this

Code: Select all

$sql = "SELECT p.*,pd.* FROM `" . DB_PREFIX . "product` `p` LEFT JOIN `" . DB_PREFIX . "product_description` `pd` ON (`p`.`product_id` = `pd`.`product_id`)";
Please review this.

What you describe here has nothing to do with what's shown on your screenshot. According to the latter, it complained about line 2250 in admin/model/catalog/product.php (function getDiscounts). You wrongly called this function with $product_id=null.

Thank you for your reply. This is fresh Opencart 4.1.0.3 and getDiscounts is default function which is called on Product List page. Here is the screenshot https://prnt.sc/6mOe41J08wgI

This is default product query https://prnt.sc/ZBW_21Knk7z6 when we filter the product model it Left Join the "product_code" table and there is no data in this table for this product that's why it is fetching blank product_id.
