我正在尝试创建表单并使用wp\\U mail将其发送到我的电子邮件地址。我的wp\\u mail（）代码是：

if($_POST["submit"]) {
    $to="my email";
    $subject ="My subject";     
    $sender=$_POST["sendername"];
    $senderEmail=$_POST["senderEmail"];
    $message=$_POST["message"];
    $name_title=$_POST["name_title"];   

    $mailBody = "<b><span style=\'color: red;\'>Name:</span></b> $name_title $sender\\n<br/>
                 <b>Email:</span></b> $senderEmail\\n\\n<br/><br/>
                 <b>Message:</b> $message";

    $mail_sent = wp_mail( $to, $subject, $mailBody );
    }

为了更改发件人地址，我在函数中添加了以下过滤器。php

/* adding support for html emails*/
add_filter( \'wp_mail_content_type\',\'wpse27856_set_content_type\' );
function wpse27856_set_content_type(){
    return "text/html";
}

/* from address */
add_filter( \'wp_mail_from\', \'my_mail_from\' );
function my_mail_from( $email )
{
    return $senderEmail;
}

/* from name*/
add_filter( \'wp_mail_from_name\', \'my_mail_from_name\' );
function my_mail_from_name( $name )
{
    return $sender;
}

HTML格式为：

<form id="" name="" action="<?php echo get_permalink(); ?>" method="post">
<div class="form-input">
    <select name="name_title" class="name-title-input">
    <option value="" selected="selected">Select Title</option>
    <option value="Mr">Mr</option>
</div>
<div class="label-input-wrapper">
        <div class="form-label">Name</div><div class="form-input"><input type="text" name="sendername"/></div>
    </div>

    <div class="label-input-wrapper">
        <div class="form-label">E-Mail</div><div class="form-input"><input type="email" name="senderEmail" pattern="[a-z0-9._%+-]+@[a-z0-9.-]+\\.[a-z]{2,4}$" required /></div>
    </div>
    <input type="submit" value="Submit" name="submit">
</form> 

它没有将邮件表单发送到我的电子邮件。但如果我按以下方式更改过滤器，它会将表单发送到我的电子邮件：

/* from address */
add_filter( \'wp_mail_from\', \'my_mail_from\' );
function my_mail_from( $email )
{
    return "[email protected]";
}

/* from name*/
add_filter( \'wp_mail_from_name\', \'my_mail_from_name\' );
function my_mail_from_name( $name )
{
    return "my name";
}

那么，如何才能从邮件头获取发件人的电子邮件呢？

function contact_send() {
    $title   = \'New message Received\';
    $headers = array(\'From: \'.$_POST[\'full_name\'].\' <\'.$_POST[\'email_address\'].\'>\');
    $message = \'<h1>My message</h1>\';

    //Send the email
    add_filter(\'wp_mail_content_type\', create_function(\'\', \'return "text/html"; \'));
    $email = wp_mail(\'[email protected]\', $title, $message, $headers);
    remove_filter(\'wp_mail_content_type\', \'set_html_content_type\');

    return $email;
}

add_filter( \'wp_mail_from_name\', \'my_mail_from_name\' );
function my_mail_from_name( $name ) {
    return "My Name";
}

add_filter( \'wp_mail_from\', \'my_mail_from\' );
function my_mail_from( $email ) {
    return "change-this-to-your-email-address";
}
