未知列＆＃39;数组＆＃39;在＆＃39; where子句＆＃39;

SELECT `cat_name` FROM (`cat_manager`) WHERE `parent_id` = Array

Answer 1

如果您使用的是codeigniter，那么为什么不使用codiegniter活动记录库来使SQL查询将它们编写为纯SQL。

$select = $this->db->select('cat_name')
               ->from('cat_manager')
               ->where_in('parent_id', $yourArray);

$result = $this->db->get()->result_array();

Answer 2

    public function function_name()
    {
        $data = $_POST['input field name'];//align variable to data

        $query = $this->db->query("SELECT cat_name FROM cat_manager WHERE parent_id='$data'");//retrieve single item which  is equal to $data
        $result = $query->result_array();//asign it has objective array
        return $result;//return array
    }

让我知道解决方案，因为我的codeigniter模型有问题
