为什么HTML电子邮件的一部分在电子邮件客户端中显示为文本？

问题描述

我想使用Codeigniter的发送HTML电子邮件。这是我做的：

I am trying to send HTML emails with Codeigniter's email class. This is how I am doing it:

    $config = Array(
        'protocol' => 'smtp',
        'smtp_host' => 'ssl://smtp.googlemail.com',
        'smtp_port' => 465,
        'smtp_user' => '[email protected]',
        'smtp_pass' => 'password',
        'mailtype'  => 'html',
        'charset'   => 'iso-8859-1'
    );

    $this->load->library('email', $config);
    $this->email->from('[email protected]', 'Me');
    $this->email->to($email);
    $this->email->subject($subject);
    $this->email->message($html);
    $this->email->set_newline("\r\n");

    if($this->email->send()){
        return true;
    }else{
        return false;
    }

但是，当我在Gmail或Outlook中查看电子邮件时， HTML在电子邮件顶部显示为文本，电子邮件的其余部分正常显示。

However, when I view the email in Gmail or outlook, I see bunch of HTML appearing as text at the top of the email and the the rest of the email is displayed normally.

是我发送的HTML，它是我发现要测试的模板。第1到19行显示为正常文字，未呈现。

Here is the HTML I am sending, its a template that I found to test with. Lines 1 to 19 appear as normal text and is not rendered.

This is how the email looks.

为什么会是这种情况？

推荐答案

作为我们在问题评论中的对话的总结，问题似乎是 $ html 变量。该变量包含实体编码的HTML。通过 html_entity_decode 运行它解决了这个问题。

As a summary of our conversation in the question's comments, the problem appears to be the content of the $html variable. The variable contains entity encoded HTML. Running it through html_entity_decode solved the problem.
