运行以下代码时出现此错误。我不知道为什么我得到这个错误。我回显了查询以确保语法正确。我在语法检查器中检查了查询，以确保查询不包含语法错误。甚至在我的管理员的PHP中进行了测试。
产生此错误的查询是for循环中具有numberofcolor和numberofsizes的查询
错误描述：您的SQL语法有错误；检查与您的MySQL服务器版本相对应的手册以获取正确的语法，以在第1行的'1'附近使用

答案 0 :(得分：0)
$add_size_att = "INSERT INTO `attributes`( `id`, `att_type`, `att_value`) VALUES ($product_id, `size`,`$curr_size_value`)";
您在此处使用不正确的引号类型时，`应该位于字符串值附近'
$add_size_att = "INSERT INTO `attributes`( `id`, `att_type`, `att_value`) VALUES ($product_id, 'size','$curr_size_value')";
尺寸也应该为$size吗？
