[wp-hackers] iOS WP app: Featured image size problems

[Nikola Nikolov]

Can you try doing

print_r( wp_get_attachment_metadata( get_post_thumbnail_id( $post->ID ) ) );

And see what the "sizes" key of the returned array contains? In theory all
of your custom sizes data should be right there(see the function in the
codex -
http://codex.wordpress.org/Function_Reference/wp_get_attachment_metadata ).

If there are no sizes(or only the default ones are there), try the
following:

$uploads_dir = wp_upload_dir();
$thumbnail_id = get_post_thumbnail_id( $post->ID );
$file_name = wp_get_attachment_metadata( $thumbnail_id );
$file_name = $file_name && isset( $file_name['file'] ) ? $file_name['file']
: false;
if ( $file_name ) {
    include_once( ABSPATH . 'wp-admin/includes/image.php' );
    echo "Generating attachment metadata for attachment with ID {$
thumbnail_id}:\n";
    print_r( wp_generate_attachment_metadata( $thumbnail_id, $file_name ) );
} else {
    echo 'No file found';
}

This should in theory generate the attachment metadata - if you have your
sizes in the "sizes" array key, then the problem is either in your
set-up(theme/plugins), or the iOS app.

To investigate further, set-up a default install(no plugins, the default
theme - maybe add in a custom size in there) and use the iOS app to upload
a featured image for a post. Then see if the Featured image comes in your
size - if it does, then it's either your theme, or one of your plugins. If
it doesn't - it's a bug in the iOS app which you should file here -

I hope some of that helps,
Nikola
