攻击“联系表单7”代码以添加“引用者”字段

我有大约6个子域名有“联系我们”链接,我将所有这些链接发送到使用“联系表格7”的单个表单。我将?from = site-name添加到每个链接中,以便我可以在联系表单中设置$ referFrom变量。

我唯一缺少的两件事是:(1)能够将这个referFrom变量插入到每当有人提交表单时我收到的电子邮件中;(2)能够将用户重定向回他们来自的网站(存储在$ referencedFrom中)

有什么想法吗?

这是来自includes / classes.php的一些代码,我认为这些代码可能是电子邮件插入的一部分,但它没有做太多...

function mail() {
    global $referrer;
    $refferedfrom = $referrer; //HERE IS MY CUSTOM CODE
    $fes = $this->form_scan_shortcode();

    foreach ( $fes as $fe ) {
        $name = $fe['name'];
        $pipes = $fe['pipes'];

        if ( empty( $name ) )
            continue;

        $value = $_POST[$name];

        if ( WPCF7_USE_PIPE && is_a( $pipes, 'WPCF7_Pipes' ) && ! $pipes->zero() ) {
            if ( is_array( $value) ) {
                $new_value = array();
                foreach ( $value as $v ) {
                    $new_value[] = $pipes->do_pipe( $v );
                }
                $value = $new_value;
            } else {
                $value = $pipes->do_pipe( $value );
            }
        }

        $this->posted_data[$name] = $value;
        $this->posted_data[$refferedfrom] = $referrer; //HERE IS MY CUSTOM CODE
    }

我也在想我可以在这个函数的某处插入referFrom代码......

function compose_and_send_mail( $mail_template ) {
    $regex = '/\[\s*([a-zA-Z][0-9a-zA-Z:._-]*)\s*\]/';
    $callback = array( &$this, 'mail_callback' );

    $mail_subject = preg_replace_callback( $regex, $callback, $mail_template['subject'] );
    $mail_sender = preg_replace_callback( $regex, $callback, $mail_template['sender'] );
    $mail_body = preg_replace_callback( $regex, $callback, $mail_template['body'] );
    $mail_recipient = preg_replace_callback( $regex, $callback, $mail_template['recipient'] );

    $mail_headers = "From: $mail_sender\n";

    if ( $mail_template['use_html'] )
        $mail_headers .= "Content-Type: text/html\n";

    $mail_additional_headers = preg_replace_callback( $regex, $callback,
        $mail_template['additional_headers'] );
    $mail_headers .= trim( $mail_additional_headers ) . "\n";

    if ( $this->uploaded_files ) {
        $for_this_mail = array();
        foreach ( $this->uploaded_files as $name => $path ) {
            if ( false === strpos( $mail_template['attachments'], "[${name}]" ) )
                continue;
            $for_this_mail[] = $path;
        }

        return @wp_mail( $mail_recipient, $mail_subject, $mail_body, $mail_headers,
            $for_this_mail );
    } else {
        return @wp_mail( $mail_recipient, $mail_subject, $mail_body, $mail_headers );
    }
}

我找到了一个插件,可以很好地做到这一点,还有一点:

将在发送电子邮件时将所有信息添加到电子邮件末尾

首先,为了获得from变量,你必须插入

$referrer = $_GET['from'];

顶部脚本中的某个位置,至少在您插入的最后一行之前。

此外,在第二个脚本中,您必须以某种方式将值添加到$ mail_body,但由于我不知道该值是如何组成的,因此我无能为力。 这个表格的代码是否可以在某处在线获取?

插入 functions.php 或创建一个简单的插件...

<强> 1

function custom_wpcf7_special_mail_tag( $output, $name  ) {
    if ( 'from' == $name ) {
        $referredFrom = ( isset($_GET["from"]) && !empty($_GET["from"]) ) ? $_GET["from"] : '';
        $output =  $referredFrom;
    }

    return $output;
}
add_filter( 'wpcf7_special_mail_tags', 'custom_wpcf7_special_mail_tag', 10, 2 );

使用电子邮件模板中的[from]标记。

<强> 2

function add_custom_js_cf7() {
    $referredFrom = ( isset($_GET["from"]) && !empty($_GET["from"]) ) ? $_GET["from"] : '';
    if ( $referredFrom ) {
    ?>
        <script type="text/javascript">
        var from = "<?php echo $referredFrom; ?>";
        </script>
<?php }
}
add_action( 'wpcf7_enqueue_scripts', 'add_custom_js_cf7' );

并将此行添加到表单设置中的“其他设置”:

on_sent_ok: "location = from;"

如果你在某个地方宣布它,你也可以使用global $referredFrom;
