@hudatoriq: There are trac tickets here and here. The conclusion was that this is ‘broken’ on purpose to give you the ability to assign user capabilities on a per-blog basis even when the user tables are shared (something I am learning to appreciate as the number of blogs comprising the site I build and maintain grows). But allowing for definition of CUSTOM_CAPABILITIES_PREFIX in wp-config.php sounds to me like a good idea. Trac it!

Yes. Read this:

I’ve written about this in a bit more detail here:

You have an extra semicolon at the end of your else block. You don’t end blocks with ;, just statements.

Thanks Otto42, you beat me to it.

I understood what you meant the first time. That’s what the code I posted above is supposed to do (your alternative 1). It checks to see if there is anything in the biographical info field using get_the_author_description() and only prints a link if there is. It is meant to be used on the posts page, of course, because if you were already on the author page, why would you want a link to that page?

Right. The attachment being shown is chosen at random from those available, but you always have the same post coming up first. Try adding orderby=rand to the query argument.

In case you’re wondering what kind of loser would have this much time to spend on your problem the answer is a very bored loser in bed with a cold.

That’s because you have ‘showposts=1’ in your query. I thought that was on purpose.

I think you need to set the ‘post_parent’ in the get_children() call. Since you’re not in the loop, it has no way of getting at the $post variable and uses the default 0, which means all images are retrieved.

Try adding 'post_parent'=>$post->ID to the array you pass to get_children.

Doh! Sorry, my bad. I think the rest of what I wrote makes sense, though.

Weird. I assume that you’re using the integer id for the category and not the name (otherwise you need to use category_name instead of cat).

What are you doing to get the attachments?

is_author is meant for testing the role of the current user. It returns true if the currently logged in user has the author role. So (as I guess you realized) using it the way you tried to makes no sense.

I would try testing get_the_author_description(). Like this:

$desc = get_the_author_description();
if ($desc!='') { // The description is not empty
    the_author_posts_link();
}

<?php echo parse_url($_SERVER["REQUEST_URI"], PHP_URL_PATH); ?>

I take back that last correction! There is no query_posts method in WP_Query. I was right the first time.

Right. WP_Query doesn’t have a query_posts method. I meant $my_query->query();

So something like:

<?php function randomimage($size=medium,$num=1,$cat=0) {
    $my_query=new WP_Query();
    $posts=$my_query->query('showposts=1&cat='.$cat);
    foreach( $posts as $post ) {

should do it…
