联系形式7 -动态收件人电子邮件 - Contact form 7 - dynamic recipient email

Contact form 7 - dynamic recipient email

我试图从自定义字段动态抓取收件人电子邮件，并使用字符串替换来修改联系人表单7收件人电子邮件。联系表单正在发送，但似乎没有更改收件人电子邮件，因为我没有收到电子邮件。

<?php
function wpcf7_dynamic_email_field( $args ) {
    $dynamic_email = '';
    $submission = WPCF7_Submission::get_instance();
    $unit_tag = $submission->get_meta( 'wpcf7-f3936-p3933-o1' );
    // get the post ID from the unit tag
    if ( $unit_tag && preg_match( '/^wpcf7-f('d+)-p('d+)-o('d+)$/', $unit_tag, $matches ) ) {
        $post_id = absint( $matches[2] );
        $dynamic_email = get_post_meta( $post_id, 'email', true );
    }
    if ( $dynamic_email ) {
        $args['recipient'] = str_replace('emailtoreplace@email.com', $dynamic_email, $args['recipient']);
    }
    return $args;
}
add_filter( 'wpcf7_mail_components', 'wpcf7_dynamic_email_field' );
?>

我正在运行CF7 4.5.1和PHP 5.3我在这里错过了什么?

要向WPCF7 5.2版本的动态收件人发送电子邮件，我是这样做的:

function wpcf7_before_send_mail_function( $contact_form, $abort, $submission ) {
  $dynamic_email = 'email@email.com'; // get your email address...
  $properties = $contact_form->get_properties();
  $properties['mail']['recipient'] = $dynamic_email;
  $contact_form->set_properties($properties);
  return $contact_form;
}
add_filter( 'wpcf7_before_send_mail', 'wpcf7_before_send_mail_function', 10, 3 );

你想用unit标签做什么不是很清楚，但是，这里有一种解决问题的方法，

function wpcf7_dynamic_email_field( $args ) {
    //create a hidden field with your post-id
    $dynamic_email = '';
    if(isset($_POST['post-id'])){
      $post_id = $_POST['post-id'];
      $dynamic_email = get_post_meta( $post_id, 'email', true );
    }
    if ( $dynamic_email ) {
        $args['recipient'] = str_replace('emailtoreplace@email.com', $dynamic_email, $args['recipient']);
    }
    return $args;
}
add_filter( 'wpcf7_mail_components', 'wpcf7_dynamic_email_field' );

为了获得post-id填充，您可以在客户端使用javascript，或者您可以在表单加载时使用CF7动态文本扩展(参见这里的教程)将其预加载。
