Okay as the title says I need a little help finishing a small bbPress plugin.

Right now it checks each topic content against the bbPress topic-tags created from the back-end ( only those are assigned not empty tags ) and if there are matches between the tags and content it echo’s those matches found.

The only deal-breaker here is how to add those matches found the $word Variable to each topic tags when you create a new topic or edit a topic fron the front-end.

I believe you have to work with those two actions:

add_action( 'bbp_new_topic',  'function_name', 10, 5 );
add_action( 'bbp_edit_topic', 'function_name', 10, 5 );

But how do you make the connection to the database table or how it’s called.

This is the code I already made.

This Plugin was an idea because of this topic.

Opinion: Tags in bbPress, do you like it or frustration to maintain?

Some help from anybody who knows PHP and creating WP Plugins would be very cool.

Thanks..

Better hook it to bbp_new_reply_pre_set_terms here: https://bbpress.trac.wordpress.org/browser/trunk/includes/replies/functions.php#L371 and return the $words array after joining in the supplied $terms array. Similarly for topic.

I’d also suggest to have this at the very beginning:

if ( !bbp_allow_topic_tags() || !current_user_can( 'assign_topic_tags' ) )
return $terms;

Just realized that the ‘similar’ thing for topics doesn’t exist. Your method for topics is correct, and you’ll need something like this after you’ve the $words array:

$words = array_unique( array_merge( $words, wp_get_post_terms( $topic_id, bbp_get_topic_tag_tax_id(), array( 'fields' => 'names' ) ) ) );
if ( !empty( $words ) )
     wp_set_post_terms( $topic_id, $words, bbp_get_topic_tag_tax_id(), true );

The top of the code should read as (to accept the $topic_id passed by do_action):

add_action( 'bbp_new_topic',  'shmoo_auto_save_tags', 10, 1 );
add_action( 'bbp_edit_topic', 'shmoo_auto_save_tags', 10, 1 );

function shmoo_auto_save_tags( $topic_id ) {

Again, untested, but should work in principle.

Thanks I appreciate your input but I can’t make it work..

This is probably above my league. 🙁

Paste the full code again?

This is what I have right now,

First I got undifined Variable for $topic_id so I added the $topic_id = 0; at the code, Zero stands for getting the topic ID from the loop ?

Thank you so much it works..

You’re welcome. And the explanation:

First I got undifined Variable for $topic_id so I added the $topic_id = 0; at the code, Zero stands for getting the topic ID from the loop ?

Where the bbp_new_topic hook is called, the line says:

do_action( 'bbp_new_topic', $topic_id );

It calls all the functions hooked to bbp_new_topic and also passes the $topic_id parameter, which in our case is:

function shmoo_auto_save_tags( $topic_id ) {

During this stage, I do not think we’re in the loop (I maybe wrong, I haven’t checked). The topic id internally would be something different at the point of insertion, that’s why in our function we’re now passing the variable to other functions:

$bbp_topic_content = bbp_get_topic_content( $topic_id );

On a side note, you had done $topic_id = 0; at the very beginning of the function. Due to that, whatever topic id was being passed was being disregarded and instead set to 0.
