Question

我一直在查看codeigniters网站的活动记录指南，我试图在模型或控制器中找出where子句的位置？我认为它属于模型，但不确定如何实现它。 $ where =＆＃34; EmpName =＆＃39; Donny＆＃34 ;; $这 - ＆GT; DB-化合物其中（$其中）;

控制器名为Home.php

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
    class Home extends CI_Controller 
{
    public function index() 
    {

        $this->load->model('HomeModel');
        $data['records'] = $this->HomeModel->getData();
        $this->load->view('HomeView',$data);
    }
}

HomeModel.php

<?php 

class HomeModel extends CI_Model{

public function getData(){

    $query = $this->db->get('requests');
    return $query->result();
}

}

HomeView.php

<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Home View</title>
</head>
<body>
    <h1>Our DB Results:</h1>
    <?php 

foreach($records as $r){

echo $r->EmpName."   ".$r->Department."<br>";

};?>

</body>
</html>

Answer 1

试试这个

$query = $this->db->get_where('requests', array('id' => $id));

你可以使用

$this->db->where('empname', 'Donny');

Answer 2

试试这个

$query = $this->db->get_where('requests', array(  'EmpName' => 'Donny'  ));
return $query->result();

不确定在whereignign中放置where子句的位置
