有没有一种方法可以使用WordPress的wp_mail（）函数发送HTML格式的电子邮件？

来自 wp_mail抄本页面:

默认内容类型为"文本/纯文本",不允许使用HTML.但是,您可以使用" wp_mail_content_type"过滤器来设置电子邮件的内容类型.

 // In theme's functions.php or plug-in code:

function wpse27856_set_content_type(){
    return "text/html";
}
add_filter( 'wp_mail_content_type','wpse27856_set_content_type' );
 

from wp_mail codex page:

The default content type is 'text/plain' which does not allow using HTML. However, you can set the content type of the email by using the 'wp_mail_content_type' filter.

// In theme's functions.php or plug-in code:

function wpse27856_set_content_type(){
    return "text/html";
}
add_filter( 'wp_mail_content_type','wpse27856_set_content_type' );

或者,您可以在$ headers参数中指定Content-Type HTTP标头:

 $to = '[email protected]';
$subject = 'The subject';
$body = 'The email body content';
$headers = array('Content-Type: text/html; charset=UTF-8');

wp_mail( $to, $subject, $body, $headers );
 

As an alternative, you can specify the Content-Type HTTP header in the $headers parameter:

$to = '[email protected]';
$subject = 'The subject';
$body = 'The email body content';
$headers = array('Content-Type: text/html; charset=UTF-8');

wp_mail( $to, $subject, $body, $headers );

使用wp_mail函数后,请不要忘记删除内容类型过滤器. 按照可接受的答案命名,您应该在执行wp_mail之后执行以下操作:

 remove_filter( 'wp_mail_content_type','wpse27856_set_content_type' );

Don't forget to remove the content type filter after you use the wp_mail function. Following the accepted answer naming you should do this after wp_mail is executed:

remove_filter( 'wp_mail_content_type','wpse27856_set_content_type' );

我将在下面分享另一种简单的方法.甚至您也可以根据需要设置邮件正文的样式.也许对您有帮助.

 $email_to = '[email protected]';
$email_subject = 'Email subject';

// <<<EOD it is PHP heredoc syntax
$email_body = <<<EOD
This is your new <b style="color: red; font-style: italic;">password</b> : {$password}
EOD;

$headers = ['Content-Type: text/html; charset=UTF-8'];

$send_mail = wp_mail( $email_to, $email_subject, $email_body, $headers );

Another easy way I'm going to share below. Even you can style your mail body as your wish. Maybe it's helpful for you.

$email_to = '[email protected]';
$email_subject = 'Email subject';

// <<<EOD it is PHP heredoc syntax
$email_body = <<<EOD
This is your new <b style="color: red; font-style: italic;">password</b> : {$password}
EOD;

$headers = ['Content-Type: text/html; charset=UTF-8'];

$send_mail = wp_mail( $email_to, $email_subject, $email_body, $headers );

使用ob_start,因为这将允许您使用WP变量/函数,例如bloginfo等.

制作一个PHP文件并将您的HTML粘贴到该文件中(如果需要,请在该php文件中使用wp变量).

使用以下代码:

  $to = 'Email Address';
 $subject = 'Your Subject';

 ob_start();
 include(get_stylesheet_directory() . '/email-template.php');//Template File Path
 $body = ob_get_contents();
 ob_end_clean();

 $headers = array('Content-Type: text/html; charset=UTF-8','From: Test <[email protected]>');
 wp_mail( $to, $subject, $body, $headers );
 

这将使您的代码保持干净,并且由于ob_start,我们还将节省加载文件的时间.

Use ob_start, because this will allow you to use WP variables/functions like bloginfo etc.

make a PHP file and paste your HTML in that file(use wp variables inside that php file if needed).

Use the below code:

 $to = 'Email Address';
 $subject = 'Your Subject';

 ob_start();
 include(get_stylesheet_directory() . '/email-template.php');//Template File Path
 $body = ob_get_contents();
 ob_end_clean();

 $headers = array('Content-Type: text/html; charset=UTF-8','From: Test <[email protected]>');
 wp_mail( $to, $subject, $body, $headers );

this will keep your code clean and due to ob_start we will also save the time of loading the file.
