How to do a simplo mysql_query('select * from name of my DB); on features module?

On catalog\controller\module\featured.php

I want to show all my products, but my queries are failing.

I think it is just mysql_query('select * from' .DB_PREFIX);

but it is not working.

Use what is already in the model class. Don' t bother writing that mess you have above. This is the function in model file product.php that is used for gathering featured items:

Code: Select all

public function getProduct($product_id) {
		if ($this->customer->isLogged()) {
			$customer_group_id = $this->customer->getCustomerGroupId();
		} else {
			$customer_group_id = $this->config->get('config_customer_group_id');
		}	
				
		$query = $this->db->query("SELECT DISTINCT *, pd.name AS name, p.image, m.name AS manufacturer, (SELECT price FROM " . DB_PREFIX . "product_discount pd2 WHERE pd2.product_id = p.product_id AND pd2.customer_group_id = '" . (int)$customer_group_id . "' AND pd2.quantity = '1' AND ((pd2.date_start = '0000-00-00' OR pd2.date_start < NOW()) AND (pd2.date_end = '0000-00-00' OR pd2.date_end > NOW())) ORDER BY pd2.priority ASC, pd2.price ASC LIMIT 1) AS discount, (SELECT price FROM " . DB_PREFIX . "product_special ps WHERE ps.product_id = p.product_id AND ps.customer_group_id = '" . (int)$customer_group_id . "' AND ((ps.date_start = '0000-00-00' OR ps.date_start < NOW()) AND (ps.date_end = '0000-00-00' OR ps.date_end > NOW())) ORDER BY ps.priority ASC, ps.price ASC LIMIT 1) AS special, (SELECT points FROM " . DB_PREFIX . "product_reward pr WHERE pr.product_id = p.product_id AND customer_group_id = '" . (int)$customer_group_id . "') AS reward, (SELECT ss.name FROM " . DB_PREFIX . "stock_status ss WHERE ss.stock_status_id = p.stock_status_id AND ss.language_id = '" . (int)$this->config->get('config_language_id') . "') AS stock_status, (SELECT wcd.unit FROM " . DB_PREFIX . "weight_class_description wcd WHERE p.weight_class_id = wcd.weight_class_id AND wcd.language_id = '" . (int)$this->config->get('config_language_id') . "') AS weight_class, (SELECT lcd.unit FROM " . DB_PREFIX . "length_class_description lcd WHERE p.length_class_id = lcd.length_class_id AND lcd.language_id = '" . (int)$this->config->get('config_language_id') . "') AS length_class, (SELECT AVG(rating) AS total FROM " . DB_PREFIX . "review r1 WHERE r1.product_id = p.product_id AND r1.status = '1' GROUP BY r1.product_id) AS rating, (SELECT COUNT(*) AS total FROM " . DB_PREFIX . "review r2 WHERE r2.product_id = p.product_id AND r2.status = '1' GROUP BY r2.product_id) AS reviews, p.sort_order FROM " . DB_PREFIX . "product p LEFT JOIN " . DB_PREFIX . "product_description pd ON (p.product_id = pd.product_id) LEFT JOIN " . DB_PREFIX . "product_to_store p2s ON (p.product_id = p2s.product_id) LEFT JOIN " . DB_PREFIX . "manufacturer m ON (p.manufacturer_id = m.manufacturer_id) WHERE p.product_id = '" . (int)$product_id . "' AND pd.language_id = '" . (int)$this->config->get('config_language_id') . "' AND p.status = '1' AND p.date_available <= NOW() AND p2s.store_id = '" . (int)$this->config->get('config_store_id') . "'");
		
		if ($query->num_rows) {
			$query->row['price'] = ($query->row['discount'] ? $query->row['discount'] : $query->row['price']);
			$query->row['rating'] = (int)$query->row['rating'];
			
			return $query->row;
		} else {
			return false;
		}
	}
The conditional is based on the product_id sent as an argument from the control file here:

Code: Select all

$products = explode(',', $this->config->get('featured_product'));		$products = array_slice($products, 0, (int)$setting['limit']);
		
		foreach ($products as $product_id) {
