Post ID Action wpcf7_before_send_mail

Look at the wpcf7_special_mail_tag function in includes/mail.php to see how it retrieves post id for [_post_id] special mail tag.

Hi Takayuki, thanks for the response!

I was trying to use the code from there but had no luck.

add_action('wpcf7_before_send_mail', 'wpcf7_update_email_body');

function wpcf7_update_email_body($contact_form) {

  $submission = WPCF7_Submission::get_instance();
  $url = $submission->get_meta( 'url' );
  $unit_tag = $submission->get_meta( 'unit_tag' );

	if ( $unit_tag
		&& preg_match( '/^wpcf7-f(\d+)-p(\d+)-o(\d+)$/', $unit_tag, $matches ) ) {
		$post_id = absint( $matches[2] );

		if ( $post = get_post( $post_id ) ) {
				$the_post_id = (string) $post->ID;
				$the_post_name = $post->post_name;
				$the_post_title = $html ? esc_html( $post->post_title ) : $post->post_title;
				$test_variable = 'hai';
		}
	} 

  if ( $submission ) {
   $mail = $contact_form->prop('mail');
   $mail['body'] .= '<p> '. $url .' '. $the_post_id .' '. $the_post_name .''. $the_post_title .''. $test_variable .'</p>';
   $contact_form->set_properties(array('mail' => $mail));
  }
}

The only variable that gets printed on my mail is $url. That means that the “if ( $unit_tag….” statement is not working.

Could you point me out on the right direction? I’m sure I must be doing something wrong.

Thanks!

Can I see the form?

Sure!

This is what I have on my form:

[hidden hidden-300 "post_title"]

[hidden hidden-144 "custom_field-contenido_noticias"]

<p>Compartir con: [email compartir-email] </p>

<p>[submit "Enviar"]</p>

I’m not using the special tags since i’m outside of the main loop and this goes in my footer. I did try putting the form (php + shortcode) inside the loop, and special mail tags didn’t work.

Im trying to add the content this way because of this problem:

Thanks for your help!

I meant the URL of the page, but it’s OK as I found the cause.

For the same reason as special mail tags, your code doesn’t work outside WP loop. The unit tag isn’t in wpcf7-f(\d+)-p(\d+)-o(\d+) format there.

Besides, Contact Form 7 doesn’t support these “hidden” tags.

[hidden hidden-300 "post_title"]

[hidden hidden-144 "custom_field-contenido_noticias"]

Hmm I’m not sure I explained my self correctly. unit tag has a value, but it’s the form id, so it doesnt help either.

Anyways, what I finally did to get this working is the following:

add_action('wpcf7_before_send_mail', 'wpcf7_update_email_body');

function wpcf7_update_email_body($contact_form) {

  $submission = WPCF7_Submission::get_instance();
  $url = $submission->get_meta( 'url' );

 // Super nice wordpress function
  $postid = url_to_postid( $url );
  // Get ACF content
  $custom_content = get_field('contenido_noticias' , $postid);	

   if ( $submission ) {
   	$mail = $contact_form->prop('mail');
   	$mail['body'] .= $custom_content;
   $contact_form->set_properties(array('mail' => $mail));
  }
}

Since i’m able to get the url of the post I can use the wordpress function url_to_postid to get the post id. Then I can do whatever I need! Simple as that ??

Thanks!
