设置标题后无法在电子邮件中发送链接

问题描述：

I am not able send links in email.
I am using wp_mail() function to send email.
When i set header $headers .= "Content-Type: text/html; "; this header removes href attribute in received email.

i am using wp_editor for textarea. I also tried html textarea but the result was same.

When i send mail without setting header, i am getting anchor tag as text.
<a href=\'http://example.com\'>Example</a>

here is my code.

jQuery('.for_email').click(function(e){
        e.preventDefault();
        var mail_data = jQuery('.email_popup_form').serialize();
        //console.log(mail_data);
        jQuery.ajax({
            url:"<?php echo admin_url('admin-ajax.php'); ?>",
            data:'action=mail_link_popup&'+mail_data,
            success:function(res)
            {
                //console.log(jQuery('#mycustomeditor_afds_ifr').contents().find('#tinymce').html());
            }
        });
    });

And this is php code

add_action('wp_ajax_mail_link_popup','mail_link_popup');
function mail_link_popup()
{
//  $headers .= "MIME-Version: 1.0
";

    $headers .= "Content-Type: text/html; 
";
    wp_mail($_REQUEST['to_email'],$_REQUEST['subject'],$_REQUEST['message_test'],$headers);
}

Here is HTML form

 <div class="modal fade" id="email_link_myModal" role="dialog">
    <div class="modal-dialog modal-lg">

      <!-- Modal content-->
      <div class="modal-content">

Nothing is wrong with the code. I just added message body in stripslashes()

add_action('wp_ajax_mail_link_popup','mail_link_popup');
function mail_link_popup()
{
    $headers = 'Content-type: text/html;charset=utf-8';
    wp_mail($_REQUEST['to_email'],$_REQUEST['subject'],stripslashes($_REQUEST['message_test']),$headers);

}

And it's working now

Thats not how content header works in Wordpress. You need to set header through add_filter

add_filter( 'wp_mail_content_type', 'setHeader' );
wp_mail( 'me@example.net', 'The subject', '<a href="http://some.com"></a>' );
remove_filter( 'wp_mail_content_type', 'setHeader' ); 

function setHeader(){
    return 'text/html';
}

P.S. Do not forget to reset content types.
