我想从控制器传递字符串到视图 . 所以我在Controller页面的If-Else子句中写了这样的$ data ['emailstr]和['emailfail']

$this->load->library('email', array('mailtype'=>'html'));//default mailtype is 'text'
                $this->email->from('supanat_thana@hotmail.com', "Webmaster");
                $this->email->to($this->input->post('email'));
                $this->email->subject("Confirm your account");
                $message = "<p>Thank you for register!</p>";
                $message .= "<p><a href='".base_url()."register/activate_user'>Click Here</a> To Activate your Account </p>";
                $this->email->message($message);



                    if($this->email->send())
                    {
                        $data['emailstr'] = "email has been sent";
                    }
                    else
                    {
                        $data['emailfail'] = "could not send the email.";
                    }



                $this->load->view('regislogin/success', $data);

但是在viewpage中，我可以编写成功的字符串电子邮件，但是在$ emailfail字符串上发生了错误：未定义的变量：emailfail

<DOCTYPE! html>
<html>
<head>
    <title> Register </title>
    <meta charset="utf-8">
</head>
<body>
<?php
        echo "<h3>Thank you for your registration</h3>";
        echo $emailstr."

";
        if($emailfail != null) {echo $emailfail."

";} else{}
        echo anchor('home', 'กลับสู่หน้าหลัก');

?>
</body>
</html>

我应该怎么做？

    这是因为：

    if($this->email->send())
{
    $data['emailstr'] = "email has been sent";
}
else
{
    $data['emailfail'] = "could not send the email.";
}

    $ data ['emailstr']＆$ data ['emailfail']

    如果您的外部条件不成功，则未初始化 . 我认为你的情况会发生这种情况 .

    使用 isset() 而不是 !=null . 您可以't run a comparison on a value that doesn'存在，但 isset() 确定变量是否为 set 且不是 NULL .

    if(isset($emailfail)) {echo $emailfail."

    ";} else{}

    而不是像下面发送字符串发送数组并检查

    $key = md5(uniqid());
$this->load->library('email', array('mailtype'=>'html'));//default mailtype is 'text'
$this->email->from('supanat_thana@hotmail.com', "Webmaster");
$this->email->to($this->input->post('email'));
$this->email->subject("Confirm your account");
$message = "<p>Thank you for register!</p>";
$message .= "<p><a href='".base_url()."register/activate_user/$key'>Click Here</a> To Activate your Account </p>";

$this->email->message($message);
            if($this->register_model->add_temp_user($key))
            {
                if($this->email->send())
                {
                    $data['emailstatus'] =   "success"; 
                    $data['emailstr'] =   "email has been sent";
                }
                else
                {
                    $data['emailstatus'] =   "fail";
                    $data['emailfail'] = "could not send the email.";
                }
            }
            $this->load->view('regislogin/success', $data);

    在View中查看emailstatus，如下所示

    <DOCTYPE! html>
<html>
<head>
<title> Register </title>
<meta charset="utf-8">
</head>
<body>
   <?php
   if($this->input->post("btn"))
   {
        echo "<h3>Thank you for your registration</h3>";
        echo $emailstr."

    ";
        if($emailstatus != "success") {echo $emailfail."

    ";} else{}
        echo anchor('home', 'กลับสู่หน้าหลัก');
   }else{
        echo "<h3>เข้าสู่ระบบแล้ว</h3>";
        echo "<pre>";
        print_r($this->session->all_userdata());
        echo "</pre>";
        echo anchor('login/logout', 'Logout')."
    "; 
        echo anchor('home', 'กลับสู่หน้าหลัก');
   }
?>
</body>
</html>

    也许我们应该“为同一个变量分配不同的值”而不是命名两个不同的变量 .

    if($this->email->send())
{
    $data['message'] = "email has been sent";
}
else
{
    $data['message'] = "could not send the email.";
}

    另外，我想以后您可能想要使用会话闪存数据 . 使用flash数据显示信息就像你的例子一样方便 .

    $this->session->set_flashdata('msg_to_display',$data['message']);
redirect('/your/controller');

    在View页面中，可以访问它

    <?php echo $this->session->userdata('msg_to_display'); ?>

    关键是它在重定向后在会话中设置消息，但是一旦刷新页面，消息就已经消失了 .
