What i’d like to do is have a second input box that people can add information in alongside their activity post. I want to be able to access this field when displaying their streams at all times. The field will contain a generated md5(hash).

buddypress/bp-themes/bp-default/activity/post-form.php

I have modified this template to include the appropriate extra field, it has an ID and looks great. The extra field is to choose a band, music track or genre to talk about, adding focus to the conversation.

Can anybody help me to capture this md5 hash, for display in my activity streams?

[gabrielcrowe]

I think this is what i want:

https://buddypress.org/forums/topic/extending-activity-how-to-store-additional-info

And i’v implimented a simple plugin:

function add_trackmeta_to_activity( $content, $user_id, $activity_id ) {

bp_activity_update_meta( $activity_id, ‘trackmd5’, md5($_POST[‘trackstr’]) );

}

add_action( ‘bp_activity_posted_update’, ‘add_trackmeta_to_activity’, 10, 3 );

And it does not crash, or complain, but where does my data go? and how can i access it in my templates?

[gabrielcrowe]

oh lordy, i think i sorted it, and for those interested, here is the deal:

– in post-form.php, i have another input field with the ID: ‘trackstr’

– create a plugin in wp-content/plugins: ‘bp-custom.php’

– customise the below function to your custom capture needs:

function add_trackmeta_to_activity( $content, $user_id, $activity_id ) {

bp_activity_update_meta( $activity_id, ‘trackmd5’, md5($_POST[‘trackstr’]) );

}

add_action( ‘bp_activity_posted_update’, ‘add_trackmeta_to_activity’, 10, 3 );

function my_trackmeta() {

$my_trackmeta = bp_activity_get_meta( bp_get_activity_id(), ‘trackmd5’ );

//if (is_user_logged_in()) : {

echo ‘<span class=\’trackmeta-md5\’>(‘ . $my_trackmeta . ‘)</span>’;

//}

//endif;

}

add_action( ‘bp_activity_entry_meta’, ‘my_trackmeta’ );

… additional metadata is captured and stored with your posts.

sorry for not searching and readin up on this before i jumped in and gave it a go chaps and chapettes, but here is how i solved my own problem anyhow.

great thanks! how do you get to show a list of all the tracks that have been posted?? not the activity but just the tracks..

could you explain this a bit more..could it be extended to include attachments to the update?

thanks

[gabrielcrowe]

Well, it looks like i spoke too soon.

I cannot get: any $POST’ed information inside here:

function add_trackmeta_to_activity( $content, $user_id, $activity_id ) {

bp_activity_update_meta( $activity_id, ‘trackmd5’, md5($_POST[‘trackstr’]) );

}

$_POST[‘trackstr’] was returning an empty string, md5 hashed.

can anyone here jump in and help? why cant i get posted items inside my bp-custom.php?

[Xevo]

Cant you just add activity meta? Haven’t tried this myself, but shouldn’t be that hard.

[gabrielcrowe]

more experimentation leads me to this solution:

items from the form are passed through global.js

i found and modified the posted items to include /match my new fields:

/* Default POST values */

var object = ”;

var item_id = j(“#whats-new-post-in”).val();

var content = j(“textarea#whats-new”).val();

var artist = j(“input#artist”).val();

var track = j(“input#track”).val();

/* Set object for non-profile posts */

if ( item_id > 0 ) {

object = j(“#whats-new-post-object”).val();

}

j.post( ajaxurl, {

action: ‘post_update’,

‘cookie’: encodeURIComponent(document.cookie),

‘_wpnonce_post_update’: j(“input#_wpnonce_post_update”).val(),

‘content’: content,

‘artist’: artist,

‘track’: track,

‘object’: object,

‘item_id’: item_id

},

and it worked just fine. _POSTed items are now available in my bp-custom.

@gabrielcrowe Have you dumped the whole $_POST variable to see what it looks like when bp_activity_posted_update fires? Is it totally empty, or are you just failing to populate $_POST[‘trackstr’]?

My guess is that it’s an AJAX issue. Activity updates are handled near the top of bp-default/_inc/global.js. The reason it’s not getting written to $_POST is because it’s not being submitted as a form at all. I’m not really that great with jQuery, but I think you might have to unbind the bp-default handler for input#aw-whats-new-submit, then reproduce that javascript in your own plugin, with additional code to grab the content of your track box and submit it to your custom function.

[Boone Gorges]

Ha ha, we were writing at the same time

[dre1080]

the summary on this? how do we get it to work?

[gabrielcrowe]

in summary:

when you post items from a modified post-form.php you’re sending them through some ajax, and functions inside global.js.

what i had to do was edit the values that were passed into the ajax inside global js.

i have 3 fields, artist, track and cover.

j.post( ajaxurl, {

action: ‘post_update’,

‘cookie’: encodeURIComponent(document.cookie),

‘_wpnonce_post_update’: j(“input#_wpnonce_post_update”).val(),

‘content’: content,

‘artist’: artist, <<<

‘track’: track, <<<

‘cover’: cover, <<<

‘object’: object,

‘item_id’: item_id

},

(arrows added for effect)

after that, a function in bp-custom.php can pick them up and use them as metas for the post.

[dre1080]

cool, thanks! 2 more questions

1) how do you get to show a list of all the tracks that have been posted?? not the activity but just the tracks..can this be done?

2) any idea if i wanted it to pick up when i wrote a ‘#’ in the post form?? like i wrote #artist and it turns the #artist into a link for that artist..? like how the @ mention works…

[gabrielcrowe]

with number 1, id assume you’d have to loop all updates and pull out the meta on the track information.

with number 2, where would you send the link? to a webservice?

[dre1080]

im not much of a coder so do you know of any example code i could use to pull out the meta on the track information?

the link to point to a page which has all the updates in which users have used #artist for that particular artist, for example you click on #artist in an update, it takes you to a page which has all the updates that have #artist in them, you click on #ARTIST2 in an update it takes you to a page which has all the updates that have #ARTIST2 in them, n so on..

[gabrielcrowe]

lol, just so you know: this is what i’m working on right now. lol. i’ll let you know IF i can get it working.

[dre1080]

lol greeat…i hope you manage..please do letme know how it turns out..

thanks

[dre1080]

followed all the steps cant seem to get this working, it comes up blank…any idea why?

[CricketLaChica]

Thanks a lot for this, works like a charm!

[matom]

This works fine for me too, thanks – but it works only for personal activity updates and I really need it to work on group updates.

Is there a different action I need to hook this to to add meta data to group updates?

This is what I’ve got in my functions.php

`function add_title_to_activity( $content, $user_id, $activity_id ) {
bp_activity_update_meta( $activity_id, ‘activity_title’, $_POST );
}

add_action( ‘bp_activity_posted_update’, ‘add_title_to_activity’, 10, 3 );`

[matom]

Found it – it needs to be hooked to bp_groups_posted_update:

`add_action( ‘bp_groups_posted_update’, ‘add_title_to_group_activity’, 10, 4 );`

[matiou34]

Hi,
Do you know how to add a text field in the activity stream ?
