I am having a similar kind of problem. I am trying to display this though on the homepage of my WPMU install using timthumb.php, which I have installed my homepage theme directory. I am putting all the code in the functions.php file, which I think may be causing the problem. Here is my code, any help would be great:

function get_recent_blogposts_featured_nfl($blog_id,$show){
wp_reset_query();
switch_to_blog($blog_id);
global $post;?>
have_posts()) : $my_query->the_post();
$do_not_duplicate = $post->ID; ?>
<img src="/tools/timthumb.php?src=ID, “thumb”, $single = true); ?>&h=150&w=350&zc=1″ /><a href="” rel=”bookmark”>

<?php restore_current_blog();
}

Thanks,
Grant

I am reading through the documentation right now, figuring out how this may work. Idea’s off the top of your head?

I was wondering if we could rewrite this function so we can eliminate the custom field

function sp_get_image($num = 0) {
global $post;
$children = get_children(array(
‘post_parent’ => $post->ID,
‘post_type’ => ‘attachment’,
‘post_mime_type’ => ‘image’,
‘orderby’ => ‘menu_order’,
‘order’ => ‘ASC’
));

$count = 0;
foreach ((array)$children as $key => $value) {
$images[$count] = $value;
$count++;
}
if(isset($images[$num]))
return wp_make_link_relative(wp_get_attachment_url($images[$num]->ID));
else
return false;
}

BUT, I think I figured out what is stopping us. If I visit the URL that it outputs, it gives me the following error:

=========================================

Warning: mkdir(./cache) [function.mkdir]: Permission denied in /home/socal/public_html/wp-content/themes/agent_10/tools/timthumb.php on line 454

=========================================

Visit the following URL to view the error. At this point I am not sure why it’s returning permission denied.

http://searchonsocal.com/wp-content/themes/agent_10/tools/timthumb.php?src=/wp-content/blogs.dir/1/files/2009/09/wordpress_normal.jpg&h=150&w=200&zc=1

For instance, try using the following code inside the loop in your template:
<?php $curSite = get_current_site(1); echo $curSite->path; die(); ?>
If that prints something, then try:
<?php echo get_blog_option($blog_id,'fileupload_url'); die(); ?>
If that prints something, try:
<?php echo get_blog_option($blog_id,'upload_path'); ?>
Finally, if all of those have printed some output, try:
<?php echo get_post_meta($post->ID, "post-img", true); ?>

That will help you diagnose which functions are failing or not returning anything.

For example,

http://domain.com/wp-content/themes/theme/tools/timthumb.php?src=/&h=150&w=200&zc=1

Any thoughts?

Do you happen to know which version of PHP you’re running on your server? It just occurred to me that the way I have this written, it will only work in PHP5.

You could try replacing echo get_current_site(1)->path; with $curSite = get_current_site(); echo $curSite->path; and see if that makes a difference.

If that still fails, try breaking up the PHP into separate lines (start a new line after each semi-colon in the PHP code or after each opening <?php tag.
