Hi, I have a problem with configuration of product-list.tpl

 

I have added a new table in the database and I have added in this query in category.php

$sql = 'SELECT p.*, product_shop.*, stock.out_of_stock, IFNULL(stock.quantity, 0) as quantity, MAX(product_attribute_shop.id_product_attribute) id_product_attribute, product_attribute_shop.minimal_quantity AS product_attribute_minimal_quantity, pl.`description`, pl.`description_short`, pl.`available_now`,
					pl.`available_later`, pl.`link_rewrite`, pl.`meta_description`, pl.`meta_keywords`, pl.`meta_title`, pl.`name`, MAX(image_shop.`id_image`) id_image,
					il.`legend`, m.`name` AS manufacturer_name, cl.`name` AS category_default,
					DATEDIFF(product_shop.`date_add`, DATE_SUB(NOW(),
					INTERVAL '.(Validate::isUnsignedInt(Configuration::get('PS_NB_DAYS_NEW_PRODUCT')) ? Configuration::get('PS_NB_DAYS_NEW_PRODUCT') : 20).'
						DAY)) > 0 AS new, product_shop.price AS orderprice
				FROM `'._DB_PREFIX_.'category_product` cp
				LEFT JOIN `'._DB_PREFIX_.'product` p
					ON p.`id_product` = cp.`id_product`
				'.Shop::addSqlAssociation('product', 'p').'		
				LEFT JOIN `'._DB_PREFIX_.'product_attribute` pa
				ON (p.`id_product` = pa.`id_product`)
				'.Shop::addSqlAssociation('product_attribute', 'pa', false, 'product_attribute_shop.`default_on` = 1').'
				'.Product::sqlStock('p', 'product_attribute_shop', false, $context->shop).'
				LEFT JOIN `'._DB_PREFIX_.'category_lang` cl
					ON (product_shop.`id_category_default` = cl.`id_category`
					AND cl.`id_lang` = '.(int)$id_lang.Shop::addSqlRestrictionOnLang('cl').')
				LEFT JOIN `'._DB_PREFIX_.'product_lang` pl
					ON (p.`id_product` = pl.`id_product`
					AND pl.`id_lang` = '.(int)$id_lang.Shop::addSqlRestrictionOnLang('pl').')
				LEFT JOIN `'._DB_PREFIX_.'image` i
					ON (i.`id_product` = p.`id_product`)'.
				Shop::addSqlAssociation('image', 'i', false, 'image_shop.cover=1').'
				LEFT JOIN `'._DB_PREFIX_.'image_lang` il
					ON (image_shop.`id_image` = il.`id_image`
					AND il.`id_lang` = '.(int)$id_lang.')
				LEFT JOIN `'._DB_PREFIX_.'manufacturer` m
					ON m.`id_manufacturer` = p.`id_manufacturer`
					 
				WHERE product_shop.`id_shop` = '.(int)$context->shop->id.'
					AND cp.`id_category` = '.(int)$this->id
					.($active ? ' AND product_shop.`active` = 1' : '')
					.($front ? ' AND product_shop.`visibility` IN ("both", "catalog")' : '')
					.($id_supplier ? ' AND p.id_supplier = '.(int)$id_supplier : '')
					.' GROUP BY product_shop.id_product';

this LEFT JOIN

LEFT JOIN `'._DB_PREFIX_.'acquisto_unico` au
ON cp.`id_product` = au.`id_prodotto`
'.Shop::addSqlAssociation('acquisto_unico', 'au').'

If cp.id_product = au.id_prodotto, this left join add a boolean value called 'controllo'.

But I can't display it in product-list.tpl

I have called it with this code

<span>{$product.controllo|escape:'htmlall':'UTF-8'}</span>

Anyone can help me? (Sorry for my English, I don't speak it very well)

 Add the red part code

 

 

$sql = 'SELECT p.*, product_shop.*, stock.out_of_stock, IFNULL(stock.quantity, 0) as quantity, MAX(product_attribute_shop.id_product_attribute) id_product_attribute, product_attribute_shop.minimal_quantity AS product_attribute_minimal_quantity, pl.`description`, pl.`description_short`, pl.`available_now`,

pl.`available_later`, pl.`link_rewrite`, pl.`meta_description`, pl.`meta_keywords`, pl.`meta_title`, pl.`name`, MAX(image_shop.`id_image`) id_image,

il.`legend`, m.`name` AS manufacturer_name, cl.`name` AS category_default, au.`id_prodotto` as new_table_field

 

 

 

and then

<span>{$product.new_table_field|escape:'htmlall':'UTF-8'}</span>

Thank you for your answer. I have tried whith your code but it doesn't work. I explain you better. The table what I have created has 3 field ('id_prodotto','id_utente','controllo'). When an user buy one product new row was added in the table with id_product, id_customer and 1 for the field controllo.

With the left join I want to read the field 'controllo' and if controllo = 1 I want to show a different button in the product list, but I can't assign the result of left join to an array.

 

Thank for help
