Hi

I want the thumbnail to appear on the topic
Search results found a plugin similar to the function I’m hoping for

bbpress-topic-thumbnails
https://wordpress.org/plugins/bbpress-topic-thumbnails/

I want to add one more feature in this plugin.
With this plugin, thumbnails of all forum topics are displayed

I only want to use this feature for 1 specific forum
reason for write topic is because the plugin has not been updated for a long time.

So I ask for help here

code is

/*Hooks into the loop-topic.php output to print image*/
add_action( 'bbp_theme_before_topic_title', 'bee_insert_thumbnail' );
function bee_insert_thumbnail() {

        if((!bee_catch_image() == '')){
        echo('<a href="'); 
    echo(bbp_topic_permalink() . '"><img class="bbp-topic-thumbnail"  width="100%" style="max-width: ' . get_option('thumbnail_size_w') . 'px; max-height: ' . get_option('thumbnail_size_h'). 'px; vertical-align:middle;" src="' . bee_catch_image() . '"/>' .'</a>');
        }
}

/*Function that retrieves the first image associated with the topic*/
function bee_catch_image() {
  global $post, $posts;
  $first_img = '';
  ob_start();
  ob_end_clean();
  $output = preg_match_all('/<img.+src=[\'"]([^\'"]+)[\'"].*>/i', $post->post_content, $matches);
  $first_img = $matches [1] [0];
  return $first_img;
}

Anyone can help?
Thanks

probably

$forum_id = bbp_get_topic_forum_id()
        if((!bee_catch_image() == '') && $forum_id = '12345'){

Hi @robin-w

You who always help are probably an angel.

I followed your advice and modified the code
However, thumbnails are displayed on all forums topic….

Thanks~

Hi @robin-w

echo (bbp_topic_permalink().'">

Is there a way to set forum_id here?

Thanks for always help

[Robin W]

$forum_id = bbp_get_topic_forum_id()
        if((!bee_catch_image() == '') && $forum_id == '12345'){

Hi @robin-w

Sorry, can I check more?

[Robin W]

the one above should work – I changed

$forum_id = '12345'
to
$forum_id == '12345'

[purityboy83]

hi~!

Are you a genius?
When I changed it to “$forum_id == ‘12345”, only 1 forum thumbnail was created.

Thanks~!!!!!!

Great – glad you are fixed 🙂
