[Plugin: Contact Form 7] Database entry with form send

Hello.

I found out, that I can use a so called Hook to realize that…
I tried the following code in my functions.php but it didn’t work.
The form ist send via Mail but the Meta-field did not change the value…
Did someone see the error?

Thanks for your help.

function wpcf7_vor_mailversand($cf7) {
  $current_post_id = $post->ID;
  $anmeldungen = get_post_meta($current_post_id, 'Anmeldungen', true);
  $anmeldungen++;
  update_post_meta($current_post_id, 'Anmeldungen', $anmeldungen);
}
add_action( 'wpcf7_before_send_mail', 'wpcf7_vor_mailversand' );

Hello again.

It seems that the above code is not the problem because if I try this

function mycf7_vor_mailversand($cf7) {
    $current_postid = 1952;
    $anmeldungen = '33';
    update_post_meta($current_postid, 'Anmeldungen', $anmeldungen);
}
add_action( 'wpcf7_before_send_mail', 'mycf7_vor_mailversand' );

it didn’t work either!?

Someone out there?

Nobody can help?

Now the following code works to increment my custom field.
But as you can see, it uses a fixed Post-ID… everything I try to get the Post-ID from the actual post where the form is built in failed.

function mycf7_vor_mailversand($cf7) {
    global $post;
    $current_postid = 1952;
    //$current_postid = $cf7->posted_data["_post_id"];
    //$current_postid = $_POST['post_ID'];
    //$current_postid = ($post->ID);
    $anmeldungen = get_post_meta($current_postid, 'Anmeldungen', true);
    $anmeldungen++;
    update_post_meta($current_postid, 'Anmeldungen', $anmeldungen);
}
add_action( 'wpcf7_before_send_mail', 'mycf7_vor_mailversand' );

As you can see, I even try to pass the post-id as a field from CF7.
I also tried “global $wpdb;” or “global $_post;” instead of “global $post;” because I found somebody here in the forum that someone uses it that way…

Also tried a $anmeldungen = get_post_meta($post->ID, ‘Anmeldungen’, true); without succsess.

So at last: How can a get the Post-ID of the actual post from where the form sends?

Thanks for your help.

I found a solution that works for me:

function mycf7_before_send_mail($cf7) {
// Execute this Code only for Form-ID 3!
if ( 3 == $cf7->id ) {
$my_postid = wpcf7_special_mail_tag_for_post_data( $output, ‘_post_id’ ) ;

}
}
add_action( ‘wpcf7_before_send_mail’, ‘mycf7_before_send_mail’ );

This helped me.
