Question

您好我有一个搜索结果页面，可以输出我想要的所有信息，但我只有一个小问题，我没有检索到“属性”的图像。目前我的数据库有一个属性表和一个property_images表，有关该属性的所有信息都存储在属性表中，而图像存储在property_images表中。

我的上传功能使用insert_id将图像添加到指定的property_images表并将其链接到属性。

我的问题是这个，如果我在属性表中创建一个property_image字段，我怎样才能让输出只显示property_image表中的一个图像，或者我如何将image_id添加到属性表中以便我可以输出我的搜索中有一张图片？

这是我的搜索代码：

    function get_search(){
        $property_location = $this->input->post('property_location');
        $property_bedroom = $this->input->post('property_bedroom');
        $property_bathroom = $this->input->post('property_bathroom');
        $property_status = $this->input->post('property_status');
        $property_type = $this->input->post('property_type');

        $this->db->like('property_location',$property_location);
        $this->db->like('property_beds',$property_bedroom);
        $this->db->like('property_bath',$property_bathroom);
        $this->db->like('property_state',$property_status);
        $this->db->like('property_type',$property_type);
        $query = $this->db->get('property');
        error_log($this->db->last_query());
    return $query->result();
}

    $config = array();
    $config['upload_path'] = './data/images/property_images';
