link plugin with comments

for my page i need this plugin to connect with comments. the inserted key should not be displayed before a registerd user comments the post where the shortcode is inside.

so i search the web for a solution and find this: https://wordpress.stackexchange.com/a/85160

some hours later i have a working solution for me. for people who needs this also, i want to explain this step by step:
– make a child theme from that you are working on
– make a functions.php file in the directory of the new created child theme
– insert the code from the link above
– edit the file with the following code
$post_id = 1;
to
$post_id = get_the_ID();

return '<p>' . $content . '</p>';
to
echo do_shortcode($content);

function user_has_left_comment( $post_id = 0, $user_id = 0 ) {
to
function user_has_left_comment( $post_id , $user_id = 0 ) {

– after that you create a giveaway with the option “Only logged users can get keys.”
– copy the shortcode (for example [keys id=1]
– make an new post and insert this:

[membervip]
[keys id=1]
[/membervip]

(change the id with your id!)
– after that, only a registred user who comment the giveaway post will get a key from your giveaway

i hope i can help some of you with that. as thats my first steps with php, i cant give you really support if somesthing not working. try this on a test site before you make this productive!
