Question

您好我有一个简单的图像形式，用户可以点击它，根据点击模态对话框的图像，将显示数据库中的数据列表。我有一个工作，我在mysql语句中不通过变量声明特定的列名称。我想知道如何/在哪里我将图像输入的值从视图传递给控制器，以便它可以在视图中的mysql语句中使用..我已经从控制器传递mysql语句到模型到视图。以下是我的代码。任何帮助将不胜感激，因为我是CI的新手并且abit confused.Thanks！

控制器：

      <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

    class App extends MY_Controller {

function __construct()
{
    parent::__construct();

    log_message('debug', 'App controller has been initialized');
}

public function toolsmodal()
{
    $Dept = $this->input->post('submit');
    //echo $Dept;
    $this->load->model('tools_model');
    $tools = $this->tools_model->getTools($Dept);
    $data['tools'] = $tools;
    $data['view'] = 'datatables';
    $this->load->view('templates/default', $data);
}

public function index()
{


    $data['view'] = 'datatables';
    $this->load->view('templates/default', $data);


}

public function welcome()
{
    $data['view'] = 'welcome';
    $this->load->view('templates/default', $data);
}

public function datatables()
{
    // You can safely delete this method.  It is an example.
    $data['view'] = 'datatables';
    $this->load->view('templates/default', $data);

}


    }

MODEL：

      class Tools_model extends CI_Model
      {
public function getTools($Dept)
{  

    //$query = $this->db->query("select rname,decription,DRI,developer, golive from web.reportdash where AppleStore = 'Yes'");
    $this->db->select('rname, decription, DRI, developer, golive');
    $this->db->where($Dept, 'Yes');
    $query = $this->db->get('web.reportdash');

    $tools = array();

    foreach ($query->result() as $row) {
        $tools[] = $row;
    }

    return $tools;
}

} ？＆GT;

嗨，只需修改你的模型，对于模型中的循环$ tool数组在每次写入旧数组时都会只有最后一行是你的修改

    class Tools_model extends CI_Model
      {
public function getTools($Dept)
{  

    //$query = $this->db->query("select rname,decription,DRI,developer, golive from web.reportdash where AppleStore = 'Yes'");
    $this->db->select('rname, decription, DRI, developer, golive');
    $this->db->where($Dept, 'Yes');
    $query = $this->db->get('web.reportdash');

    return $query->result();

}

} ?>

您现在可以轻松循环播放

将数据从View传递到Controller，用于CI中的Model中的sql语句
