Buddypress Group Document Store

December 24th, 2009

I just uploaded my second wordpress plugin: Buddypress Group Documents!

Group Documents creates a page within each BuddyPress group to upload and store documents.  Documents can be edited and deleted either by the owner or by the group administrator.  Document activity is logged in the main activity stream, and is also tied to the user and group activity streams.  The site administrator can set filters on file extensions, and soon (in the next update) users can set email notification preferences.  There is also a “Recent Uploads” widget than can be used to show any number of uploaded documents.

Get it while it’s hot!
Wordpress.org Plugin Download Page

Installation
Make sure WPMU and BuddyPress are installed and active.
Copy the plugin folder buddypress-group-documents/ into /wp-content/plugins/

IMPORTANT:
Be sure that the sub folder “buddypress-group-documents/documents” can be written to by the web server.  This is where all uploaded files are stored. If you are unsure of how to set directory permissions, please google, ask around, or shoot me an email.

Browse to the plugin administration screen and activate the plugin.

There will now be a “Group Documents” menu item under the “BuddyPress” menu.  Here you will find a list of all file extensions allowed for uploaded files.  Please check and make sure the list suits you.

Please don’t hesitate to contact me, especially if you run into trouble.  I will respond promptly.  email hidden; JavaScript is required

Buddypress jQuery is not defined error

December 16th, 2009

While developing a Buddypress plugin, I was running into a problem where none of my Javascript was working. Instead, Firebug was telling me: “jQuery is not defined”.  This was quite frustrating, as I could verify that the jQuery file was indeed, being loaded.  While a few other people received the same error for different reasons (corrupt files, etc.) I did not quickly find the solution for my problem.  Here it is:

Problem: Buddypress calls your plugin’s JS files BEFORE jQuery files.
This applies when you use the function wp_enqueue_script() – as you should.

Solution: Tell wp_enqueue_script your file depends on jQuery.
It turns out, wp_enqueue_script() takes a few optional parameters – the third being an array of other js files yours is dependent on.

Here’s how the call looks after the change:
wp_enqueue_script(’my-js-file’,'my-file-path.js’,array(’jquery’));

Viola!  Your js file is now loaded after jQuery and you’re good to go.

Using Custom Profile Field Data in Buddypress Templates

November 18th, 2009

I ran into what I thought would be fairly common need for Buddypress theme development, the ability to pull data from a custom user profile field and display it. After searching a bit, I could only find way to pull either random fields, or all of the fields together. So after digging around in the core files, I found the pieces to put together my own function for the task.

1. Create the file “bp-custom.php” and place it directly in the plugins folder. Note, do not place it in the “buddypress” folder, otherwise it will be overwritten when upgrading. If the file exists, simply append to it rather than creating a new one.

2. Paste the following function in:

function bp_the_site_member_profile_data($field_name = '', $echo = 1) {
  if( !$field_name ) {
    return false;
  }
  global $site_members_template;
  if( function_exists( 'xprofile_get_field_data' ) ) {
    $data = xprofile_get_field_data( $field_name,
                                     $site_members_template->member->id);
    if( $echo ) {
      echo "$data";
      return true;
    } else {
      return $data;
    }
  }
}

3. You can now use the function ‘bp_the_site_member_profile_data(’MyField’) in your templates (of course, substituting ‘MyField’ with the one you’d like to use). Note, this must be place inside a ‘Members Loop’ so that the $site_members_template variable is populated.  Odds are, you’re inserting this near other profile data already in the loop, so there should be no problems.

UPDATE:
As of BuddyPress 1.2, this functionality has been included. While in the members loop, you can use the included function: ‘bp_member_profile_data( ‘field=the field name’ )’ to much the same effect.
