Editing a function in a plugin – add_action or add_filter

Hi,

I am trying to write a plugin and I do not know how can I do it properly.

The plugin I am working on requires the editing of the “get_forum_link” function, specifically the “$link ” vatiable.

I have the code done in php but do not know how to make a plugin out of it. What and how should I use add_action or add_filter?

Thanx.

function get_forum_link( $forum_id = 0, $page = 1 ) {

global $forum;

if ( $forum_id )

$forum = get_forum( $forum_id );

if ( bb_get_option( ‘mod_rewrite’ ) )

$link = bb_get_option( ‘uri’ ) . “forum/$forum->forum_id” . ( 1 < $page ? “/page/$page” : ” );

else {

$args = array();

$link = bb_get_option( ‘uri’ ) . ‘forum.php’;

$args = $forum->forum_id;

$args = 1 < $page ? $page : ”;

$link = add_query_arg( $args, $link );

}

return apply_filters( ‘get_forum_link’, $link, $forum->forum_id );

}

```
function my_get_forum_link_filter( $link ) {

$link = 'yay'; // Whatever you want to do with the link

return $link; // Very important line!

}



add_filter( 'get_forum_link', 'my_get_forum_link_filter' );
```
That last line adds your custom filter function to the get_forum_link filters.

Thanx.

I do not know if I’ve did it right but it does not works. Am I doing something wrong?

The new $link should be

$link = bb_get_option(‘uri’) . “$forum->forum_name” . ( 1 < $page ? “/page/$page” : ” );

it all should look like:

function my_get_forum_link_filter( $link ) {

$link = bb_get_option(‘uri’) . “$forum->forum_name” . ( 1 < $page ? “/page/$page” : ” );; // Whatever you want to do with the link

return $link; // Very important line!

}

add_filter( ‘get_forum_link’, ‘my_get_forum_link_filter’ );
