Question

我正在尝试制作“相关产品”查询以搜索5个相关产品，但它会出现此错误：错误图片：http://puu.sh/eeo5n/a845ef5ba3.png

这是我的代码

    // Info current t-shirt. Normally from database
    $name = "Luftrauser T-shirt";
    $description = "Stylish LUFTRAUSERS T-shirt designed by Amon26.";
    $relatedSearch = $name . $description;

    // Query which searches for related items
    $query = $db->prepare("SELECT * FROM tbl_products WHERE name, description LIKE '%:relatedSearch%'");
    $query -> bindParam("relatedSearch", $relatedSearch, PDO::PARAM_STR);
    if($query -> execute()) {
        while($related = $query->fetch(PDO::FETCH_OBJ)) {
            echo $related->title . "</br>";
        }
    }

为什么它不返回包含我用LIKE搜索的值的行？

Answer 1

如果您希望搜索查找名称和描述并匹配EITHER

SELECT * 
FROM tbl_products 
WHERE description LIKE '%:relatedSearch%' OR name LIKE '%:relatedSearch%'

如果您希望搜索查找名称和描述并匹配BOTH

SELECT * 
FROM tbl_products 
WHERE description LIKE '%:relatedSearch%' AND name LIKE '%:relatedSearch%'

SQL LIKE中的多行搜索字符串
