我尝试在CS-Cart. 但这对我不起作用。
$category_id = 1;
$company = db_get_array(SELECT `company_id`,`lang_code`,`email`,`phone`,`address`,`city`,`state`,`country`,`zipcode`,`logos`,`company`,`timestamp`,`status`,`opening_hours` FROM `cscart_companies` WHERE `categories` LIKE '$category_id,%' OR `categories` LIKE '%,$category_id,%' OR `categories` LIKE '%,$category_id' OR `categories`='$category_id');
以上是我从数据库查询的代码，但它不起作用。
首先尝试像这样正确的查询格式（你的引号很乱）：
$company = db_get_array("SELECT company_id, lang_code, email, phone, address, city, state, country, zipcode, logos, company, timestamp, FROM WHERE LIKE '".$category_id.",%' OR statusLIKE '%,".$category_id.",%' OR LIKE ' %,".$category_id."' OR ='".$category_id."'");opening_hourscscart_companiescategoriescategoriescategoriescategories
如果这不起作用，请在此处发布错误。
但我建议对数据库查询使用占位符：请参阅文档：http ://docs.cs-cart.com/4.2.x/core/db/placeholders.html
