You are trying to use a BP Album+ template tag *outside* of the part of BuddyPress that BP Album+ has control over.
With the exception of functions that retrieve global system variables, template tags are not universal objects that work everywhere in a BP installation. Most of them only work within a specific “loop” that fetches data related to the tag.
Here’s how it works:
============ bp_album_query_pictures($args) ================
(Media template object is now filled with pictures matching query and is ready to be “looped” through)
=============== bp_album_has_pictures() =================
============ bp_album_the_picture() =================
(All media item template tags work at this point)
========================================================
========================================================
========================================================
We (and all other plugins) run “the query” for you, before loading the template, because it’s *complicated*. And since the BP Album+ query doesn’t get run until BP hands execution control over to our plugin, our template tags are not valid in the “member-header.php” file, because that file gets loaded *before* our plugin.
Now, that being said, you can be naughty and “hijack” that file.
<?php
global $bp, $pictures_template;
bp_album_query_pictures($args)
?>
<?php if ( bp_album_has_pictures() ) : ?>
<?php while ( bp_album_has_pictures() ) : bp_album_the_picture(); ?>
<a href="<?php bp_album_picture_url() ?>">
<img src='<?php bp_album_picture_thumb_url() ?>' />
</a>
<?php endwhile; ?>
<?php else : ?>
<p class="error">No Pics!</p>
<?php endif; ?>
Where $args is an array, and these are the parameters:
/**
* Returns an array of Media Item objects based on user supplied parameters
*
* @version 1.0
* @since 0.1.8
* @param int $max | Unknown function. Please add documentation.
* @param int $owner_id | The numeric member id of the member that uploaded the media
* @param string $owner_type | The system role of the member that uploaded the media
* @param int $id | The bp-album GUID for the piece of media
* @param string $ids | A comma separated list of bp-album GUIDs for multiple media items
* @param int $page | Used to set current page when traversing a multi-page data set
* @param int $per_page | Number of objects to return per page when transversing multi-page data set
* @param int string bool $privacy | Sets the privacy level of the media item
* @param bool $priv_override | Makes system ignore privacy level when returning results
* @param string $ordersort | Sets sort order of the returned data set
* @param string $orderkey | Sets which parameter to order the returned results by
* @param string $groupby | Sets how to group returned results
* @param string $tag | Tag or comma separated list of tags used to search for media items
* @param string $album | Album or albums used to search for media
* @param int $tagged_member | BuddyPress member ID to search for in media items
* @param string $adjacent | 'next' gets the next media item if it exists, 'prev' gets the previous one.
* @param bool $count | Makes system returns a count of the number of results the query will return
* @param int $offset | Shifts results page forward or backward "n" items within the returned data set
* @return bool|int|array False on failure. Int on count. Array of media item objects on success.
*/
Note, however, that this code will break with the next release of the plugin.
Enjoy!
