CakePHP3 : How can I do text searching using full-text indexes

Question

我使用下面的代码使用全文索引进行搜索

$query = $this->Posts->find()
    ->contain(['Categories' ])
    ->where([
        'MATCH(Posts.title) AGAINST(? IN BOOLEAN MODE)' => $search
]);

但我收到以下错误

SQLSTATE[HY093]: Invalid parameter number: mixed named and positional parameters

请指教

提前致谢!

尝试将您的查询重写为:

$query = $this->Posts->find()
    ->contain(['Categories'])
    ->where([
        "MATCH(Posts.title) AGAINST(:search IN BOOLEAN MODE)" 
    ])
    ->bind(':search', $search);

确保您安装了最新的 CakePHP 3.x 版本，因为这是不久前添加的。

以下方法可行，但请注意，它会使您的代码容易受到 SQL 注入(inject)攻击:

// for educational purposes only. Don't use in production environments
$query = $this->Posts->find() 
    ->contain(['Categories'])
    ->where([
        "MATCH(Posts.title) AGAINST('{$search}' IN BOOLEAN MODE)" 
    ]);
