Question

我想在其他用户的仪表板中显示公告。我想要做的是将其显示在仪表板上，用户可以在其中永久关闭公告中的通知，但是发生的是，当某个用户关闭仪表板上的公告选项卡时，所有公告都在同一位置用户类型正在被删除。所以，请您帮我弄清楚我应该使用哪种方法？谢谢！

模型

function insertItem($table, $data = NULL){
        $this->db->insert($table, $data);
    }

    function insertItems($table,$data = array()){
        $this->db->insert_batch($table, $data);
    }


    function updateItem($table, $data, $var = NULL){
        if($var != NULL){

    }

Answer 1

我假设您正在会话中存储与用户相关的数据，所以
控制器：

public function deleteAnnouncement() {
        $this->Bid_Model->updateItem('announcements', ['user_type' => 0], ['announcement_id' => $this->uri->segment(3), 'user_id' => $this->session->userdata('user_id')]);
        redirect('dashboard');
    }

Answer 2

首先，您要将第二个和第三个参数作为数组传递给模型中的updateItem()。

因此，最好像这样$var = array()而不是$var = NULL

第二，您要删除特定用户的公告，因此使用用户ID只能删除一个用户

$id = $this->session->userdata('user_id')

function updateItem($table, $data, $var = array()){
    $id = $this->session->userdata('user_id');
    if(count($var) > 0){
        $this->db->where($var);
    }
    $this->db->where('user_id', $id);
    $this->db->update($table, $data);
}

使用codeigniter按用户类型在用户的仪表板中显示公告
