WordPress MU

I've noticed that when I use the image uploader, the URL to the image ends up looking like this:

http://example.com/files/2008/07/example.jpg

Obviously this isn't a real directory - and the true URL is:

http://example.com/wp-content/blogs.dir/1/files/2008/07/example.jpg

However I use a theme where I have to copy and paste the URL of the image into a custom field for thumbnail creation. Putting the virtual URL doesn't work - but using the actual URL does work.

Is there a way to set up WPMU to just use the actual URL when it displays in your site?

"However I use a theme where I have to copy and paste the URL of the image into a custom field for thumbnail creation. Putting the virtual URL doesn't work - but using the actual URL does work."

Modification of the theme to look for the file in the upload path, then render the url would be a better approach than modifying MU.

This is the pertaining code that calls the thumbnail creation:

<?php if ( get_post_meta($post->ID, 'image', true) ) { ?> <!-- DISPLAYS THE IMAGE URL SPECIFIED IN THE CUSTOM FIELD -->

<img src="<?php echo bloginfo('template_url'); ?>/thumb.php?src=<?php echo get_post_meta($post->ID, "image", $single = true); ?>&amp;h=57&amp;w=100&amp;zc=1&amp;q=100" alt="<?php the_title(); ?>" class="th" />			

<?php } else { ?> <!-- DISPLAY THE DEFAULT IMAGE, IF CUSTOM FIELD HAS NOT BEEN COMPLETED -->

<img src="<?php bloginfo('template_directory'); ?>/images/no-img-thumb.jpg" alt="" />

<?php } ?>

What would you suggest to change there?

Any ideas?

Any thoughts?

I'm using Wordpress MU v2.6.

I would think the lack of answers means people don't know.

I guess I'm just not that easily discouraged :) There's always a solution. It's all a matter of helping each other out here and giving ideas, even if we might not know the exact way to fix things.

I did some looking around and found this which may have some relevance to the issue I've been having:

http://trac.wordpress.org/ticket/7308

Hopefully this will get integrated into WPMU v2.6.1 and help fix that issue.

I'm using WooThemes on WPMU and this is my current workaround to use the absolute URL for TimThumb.php:

<a title="Permanent Link to <?php the_title(); ?>" href="<?php the_permalink() ?>" rel="bookmark"><img src="/thumb.php?src=http://blogs.journalism.cuny.edu/wp-content/blogs.dir/<?php global $blog_id; echo $blog_id; ?>/<?php echo get_post_meta($post->ID, "image", $single = true); ?>&h=195&w=540&zc=1&q=95" alt="<?php the_title(); ?>" /></a>

Then, in your post, the image custom field should be something like:
files/2008/10/6-or-9-train.jpg instead of the full URL

i have very little experience with wordpress mu but I'm having trouble with the function get_post_meta() i can't seem to get it to work. maybe that is part of your problem?.

however to get thumbnails working I have used this instead:

function the_thumb() {
    if ( $images = get_children(array(
		'post_parent' => get_the_ID(),
		'post_type' => 'attachment',
		'numberposts' => 1,
		'post_mime_type' => 'image',)))
	{
		foreach( $images as $image ) {
			$attachmenturl=wp_get_attachment_url($image->ID);
			$attachmentimage=wp_get_attachment_image( $image->ID, 'thumbnail' );

			echo $attachmentimage; // you can put attachmenturl in the href link if you want to link to the larger image
		}
	}

}

then just call the_thumb() in the loop

@coolgates:

I, too, am using Woo Themes. I appreciate you posting your work-around to get the thumbnails working, but when I tried your solution, I got an error:

Parse error: syntax error, unexpected '<' in /usr/local/share/wordpress/wp-content/themes/flashnews/thumb.php on line 17

Was I not supposed to put your code in thumb.php?

I am also having this problem :), with a woothemes theme :)

Hey guys,

I have the solution ;-)

$root = dirname(dirname(dirname(dirname(__FILE__))));
if (file_exists($root.'/wp-load.php')) {
	require_once($root.'/wp-load.php');
} else {
	if (!file_exists($root.'/wp-config.php'))
		die;
	require_once($root.'/wp-config.php');
}

function get_out_now() { exit; }
add_action('shutdown', 'get_out_now', -1);

if( !isset( $_REQUEST[ "src" ] ) ) { die( "no image specified" ); }

// clean params before use
$src = clean_source( $_REQUEST[ "src" ] );

// set document root and clean "/files"
$doc_root = substr(get_option('upload_path'),0,-6).$src;
$src = "$root/$doc_root";

wp-content/blogs.php is very slow compared to serving the images directly.
