I tried to find a solution to the WordPress 2.7.1 gallery code problem. I checked some templates first but I was not able to identify the right one. So I searched the web and I found the solution from this blog entry, Problem with WordPress 2.7.1 and images.

I was looking into several templates like link-template.php and post-template.php but did not think about the post.php file. With his solution, I was able to solve my problem that I told you in my previous blog entry.

This was the PHP function wp_get_attachment_url at WordPress 2.7.

function wp_get_attachment_url( $post_id = 0 ) {
	$post_id = (int) $post_id;
	if ( !$post =& get_post( $post_id ) )
		return false;

	$url = '';
	if ( $file = get_post_meta( $post->ID, '_wp_attached_file', true) ) { //Get attached file
		if ( ($uploads = wp_upload_dir()) && false === $uploads['error'] ) { //Get upload directory
			if ( 0 === strpos($file, $uploads['basedir']) ) //Check that the upload base exists in the file location
				$url = str_replace($uploads['basedir'], $uploads['baseurl'], $file); //replace file location with url location
		}
	}

	if ( empty($url) ) //If any of the above options failed, Fallback on the GUID as used pre-2.7, not recomended to rely upon this.
		$url = get_the_guid( $post->ID );

	if ( 'attachment' != $post->post_type || empty($url) )
		return false;

	return apply_filters( 'wp_get_attachment_url', $url, $post->ID );
}

If you read the blog entry where I found the solution, you will see there the present PHP function wp_get_attachment_url at WordPress 2.7.1.

I just commented (using // before each line) the following four lines which was added or included or inserted at the PHP function wp_get_attachment_url at the post.php when WordPress 2.7.1 was released. You will find post.php file under wp-includes folder.

elseif ( false !== strpos($file, 'wp-content/uploads') )
				$url = $uploads['baseurl'] . substr( $file, strpos($file, 'wp-content/uploads') + 18 );
			else
				$url = $uploads['baseurl'] . "/$file"; //Its a newly uploaded file, therefor $file is relative to the basedir.

That’s it. That’s the solution to my gallery code problem. Thank you, emmanuel-georjon.
