我已经在我的联系人表单7消息正文中添加了短代码，但它不起作用。

function.php

function wpb_demo_shortcode() { 

 $output = \'<p style="font-size:11pt;font-family:Calibri,sans-serif;margin:0;">Lets stay connected!</p>\';

 return $output;
 } 
 // register shortcode
 add_shortcode(\'greeting\', \'wpb_demo_shortcode\');

/**
 * A tag to be used in "Mail" section so the user receives the special tag
 * [greeting]
 */
add_filter(\'wpcf7_special_mail_tags\', \'wpcf7_tag_tournament\', 10, 3);
function wpcf7_tag_tournament($output, $name, $html)
{
    $name = preg_replace(\'/^wpcf7\\./\', \'_\', $name); // for back-compat

    $submission = WPCF7_Submission::get_instance();

    if (! $submission) {
        return $output;
    }

    if (\'greeting\' == $name) {
        return $submission->get_posted_data("greeting");
    }

    return $output;
}

// Other Code 
add_filter( \'wpcf7_form_elements\', \'mycustom_wpcf7_form_elements\' );

function mycustom_wpcf7_form_elements( $form ) {
$form = do_shortcode( $form );

return $form;
} 

我已将此代码添加到functions.php 但是我的短代码没有在电子邮件中显示html。

Added this in the Message Body: [greeting]

非常感谢您的帮助。
