未定义的属性:CI_DB_mysql_result :: $ result

Question

我是codeigniter编程的新手.当我尝试连接数据库并从表中检索数据时,我发现错误如:

A PHP Error was encountered
Severity: Notice
Message: Undefined property: CI_DB_mysql_result::$result
Filename: models/haii.php
Line Number: 15.

A PHP Error was encountered
Severity: Warning
Message: Invalid argument supplied for foreach()
Filename: views/getquery.php
Line Number: 2

我使用此代码使用codeigniter连接数据库:

控制器:

<?php
class product extends CI_Controller
{
    function __construct()
    {
    }
    function getall()
    {
        $this->load->model('haii');
        $data['query']=$this->haii->you();
        $this->load->view('getquery',$data);
    }
}
?>      

模型:

<?php
class haii extends CI_Model
{
    function __construct()
    {
        parent::__construct();
        $this->load->database();
    }
    function you()
    {
        $query=$this->db->get('member');
        return $query->result;
    }
}
?>

视图:

<?php
foreach($query as $row)
{
    print $row->username;
    print $row->password;
    print $row->fname;
    print $row->lname;
    print $row->contact;
    print "<br>";
}
?>

Answer 1

使用return $query->result();而不是return $query->result;在您的you()功能. result是一个方法,而不是类成员.
