Hey guys,

I want to create an extra field for each activity update. Each activity shall have a URL to a picture.
How do i tell buddypress to send an extra field to the DB?
The DB: http://s14.directupload.net/file/d/2919/lkdfjytf_png.htm
the image url textfield http://s14.directupload.net/file/d/2919/2k2j9p4b_png.htm

Thats what I found so far:
global.js, line 66:
`jq.post( ajaxurl, {
action: ‘post_update’,
‘cookie’: encodeURIComponent(document.cookie),
‘_wpnonce_post_update’: jq(“input#_wpnonce_post_update”).val(),
‘content’: content,
‘object’: object,
‘item_id’: item_id,
‘imgurl’: imgurl /*added by me*/
},`
Obviously jquery is sending some stuff to “ajaxurl”. But what is that url?

Then I found ajax.php, line 177:
` if ( empty( $_POST ) && bp_is_active( ‘activity’ ) ) {
$activity_id = bp_activity_post_update( array( ‘content’ => $_POST ) );

} elseif ( $_POST == ‘groups’ ) {
if ( !empty( $_POST ) && bp_is_active( ‘groups’ ) )
$activity_id = groups_post_update( array( ‘content’ => $_POST, ‘group_id’ => $_POST ) );

} else {
$activity_id = apply_filters( ‘bp_activity_custom_update’, $_POST, $_POST, $_POST );
}`
It could be, that this is where “ajaxurl” is sending the values to… But then where is the function “bp_activity_custom_update”?

Then I found bp-activity-function.php, line 595:
` // Meta key does not exist so INSERT
if ( empty( $cur ) )
$wpdb->query( $wpdb->prepare( “INSERT INTO {$bp->activity->table_name_meta} ( activity_id, meta_key, meta_value ) VALUES ( %d, %s, %s )”, $activity_id, $meta_key, $meta_value ) );`
but this is under the function “bp_activity_update_meta”. But shouldn it be “bp_activity_post_update”?

So my goal is this: when posting an activity update, I want to send an imageurl to the db along with the activity content.

I really dont get how buddypress is inserting into the DB….
