Question

我有一个小问题，我正在尝试为用户显示消息，该消息应该采用我选择的用户的参数。

但我不确定这里出了什么问题

控制器

<?php
class User extends CI_Controller {
    public function index(){
        $this->load->view('ViewMessages');
    }
    public function view($name)
    {
        $this->load->model("Messages_Model");
        $data ['results']  = $this->Messages_model->getMessagesByPoster($name);
        $this->load->view("ViewMessages", $data);
    }
}

模型

<?php
class Messages_model extends CI_Model{
    function getMessagesByPoster($name)
    {
        $this->load->database();
        $query = $this->db->query("SELECT * FROM messages WHERE user_username='$name'");
        return $query->result();
    }
}

查看

<!DOCTYPE html>
<html>
<head>
    <title></title>
</head>
<body>
<h1>View Messages</h1>
<h2></h2>
<div id="Main">
    <?php
    foreach($results as $row){
        echo $row ->id;
        echo $row ->user_username;
        echo $row ->text;
        echo $row ->posted_at;
        echo "<br/>";
    }
    ?>
</div>
</body>
</html>

编辑：错误遇到PHP错误

严重性：注意

消息：未定义属性：User :: $ Messages_model

文件名：controllers / User.php

检查一下

控制器：（User.php）

  <?php
    class User extends CI_Controller {
        public function index(){
            $this->load->view('ViewMessages');
        }
        public function view($name)
        {
            $this->load->model("Messages_model");  //Case sensitive you have written Messages_Model
            $data ['results']  = $this->Messages_model->getMessagesByPoster($name);
            $this->load->view("ViewMessages", $data);
        }
    }

CodeIgniter未定义的属性
