CakePHP 从纯文本电子邮件中删除 HTML

Question

当在我的应用中添加新文章时，我正在使用我的 cakephp 应用 (2.2) 中的电子邮件组件向订阅的人发送电子邮件。

我使用 TinyMCE 允许管理员用户格式化文本，这会导致一些格式化 HTML 保存在数据库中（这很好）但是我想以电子邮件格式（html 和纯文本）通过电子邮件将整篇文章发送给选择加入的用户添加新文章时。这适用于 html 版本，但是如何从纯文本版本中剥离 html，同时将其保留在 html 版本中？到目前为止，这是我的代码：

public function admin_add() {
    if ($this->request->is('post')) {
        $this->NewsArticle->create();
        if ($this->NewsArticle->save($this->request->data)) {

            // If is a tech alart - send email
            if ($this->request->data['NewsCategory']['NewsCategory']['0'] == '2') {

                // Email users who have opted in to webform updates
                $usersToEmail = $this->NewsArticle->query("SELECT username, tech_email FROM users WHERE tech_email = 1");

                // Loop throughh all opt'ed in users
                foreach ($usersToEmail as $user) {

                    $this->Email->template = 'newTechAlert';
                    $this->Email->from    = 'Client Area <clientarea@someurl.co.uk>';
                    $this->Email->to      = $user['users']['username'];
                    $this->Email->subject = 'New Technical Alert';
                    // Send as both HTML and Text
                                            $this->Email->sendAs = 'both';

                    // Set vars for email
                    $this->set('techAlertTitle', $this->request->data['NewsArticle']['title']);

                    ##  NEED TO STRIP THE HTML OUT FOR NONE HTML EMAILS HERE - BUT HOW???
                    $this->set('techAlertBody', $this->request->data['NewsArticle']['body']);


                    $this->set('user', $user['users']['username']);
                    $this->Email->send();

                }

            }

Answer 1

我用：

$this->Email->emailFormat('both');

// Convert <br> to \n
$text = preg_replace('/<br(\s+)?\/?>/i', "\n", $html);
// Remove html markup
$text = trim(strip_tags($text));
// Replace multiple (one ore more) line breaks with a single one.
$text = preg_replace("/(\r\n|\r|\n)+/", "\n", $text);

$this->Email->viewVars(compact('text', 'html'));

请注意，如果您使用 foreach，则应在每次运行后重置电子邮件类以避免出现问题：

$this->Email->reset();

Answer 2

你可以使用phpstrip_tags方法 http://php.net/manual/en/function.strip-tags.php

//HTML VERSION
$this->set('techAlertHtmlBody', $this->request->data['NewsArticle']['body']);

//PLAIN TEXT VERSION
$this->set('techAlertPlainBody', strip_tags($this->request->data['NewsArticle']['body']));

您还可以将第二个参数传递给函数以仍然允许换行符或 href 标记。
