shopping cart oscommerce-CodePudding

I want to retrieve products_tax_class_ids in checkout payment page in OSCommerce shopping cart software. E.g., the user has 20 items in his shopping cart and if any of product has products_tax_class_id = 30, the site will warn him.

This code is not working.

$tax = tep_db_query("select products_tax_class_id 
                    from " . TABLE_PRODUCTS . " 
                    where products_id = '".$card[$products_id]."'");

while ($warn = tep_db_fetch_array($tax)) {
    if (warn== '30') { 
        echo "attention ....";
    } 
    else { 
        echo "..."
    }
}

How can I compare tax_class_id of products?

CodePudding user response：

You didn't point name of field in while loop.

$tax = tep_db_query("select products_tax_class_id 
                    from " . TABLE_PRODUCTS . " 
                    where products_id = '".$card[$products_id]."'");

while ($warn = tep_db_fetch_array($tax)) {
    if ($warn['products_tax_class_id'] == '30') { 
        echo "attention ....";
    } 
    else { 
        echo "..."
    }
}

And word "card" should be a "cart" I think...
