[Plugin: W3 Total Cache] Trigger upload image to CDN?

How can I check if the original thumbnail is uploaded to CDN?

I’m after the same sort of feature. I’ve got the posts and files broadcasting to the main site, and the attachments are all there, but thumbnails aren’t being upped to amazon automatically resulting in a right mess on the site. ??

I was thinking if there was a way of reverting to local files when the cdn files are unavailable, and then exporting to CDN every few weeks or month depending on traffic it would be some sort of workaround that might be easier to implement???

Hopefully someone has a suggestion…

I got this to work finally! I made a “manual” forced upload of the attachment images…

This is the code I added to the private function copy_attachment( $attachment_data, $post_id) function located in ThreeWP_Broadcast.php near the end just after wp_update_attachment_metadata( $attach_id, $attach_data ) and before the last row return $attach_id:

/*
			Start add by MS
			Upload images to Amazon CDN
		*/

		if ( defined( 'W3TC_LIB_W3_DIR' ) ) {
			require_once W3TC_LIB_W3_DIR . '/Plugin/Cdn.php';
			$w3_plugin_cdn =& w3_instance('W3_Plugin_CdnCommon');
			$upload_info = w3_upload_info();

			$local_file = $upload_dir['path'] . '/' . $attachment_data->filename_base();
			$remote_file = ltrim($upload_dir['path'] . '/' . $attachment_data->filename_base(), '/');

			// Remove "wp-content/blogs.dir/5/" from the image path in remote file
			$remove_prefix_to_path = ltrim($upload_dir['basedir'], '/');
			$remove_prefix_to_path = str_replace ( 'files', '' , $remove_prefix_to_path);
			$remove_prefix_to_path = str_replace ( 'uploads', '' , $remove_prefix_to_path);
			$remote_file = str_replace ( $remove_prefix_to_path, '' , $remote_file);

			$all_image_sizes = get_intermediate_image_sizes();
			if ($w3_plugin_cdn) {

				// Add original size image
				$files = array(
					// local_file1	=> remote_file1,
					$local_file 		=> $remote_file,
					);

				// Add all other sizes of images
				$i = 0;
				$all_files = $attachment_data->file_metadata();
				foreach ($all_image_sizes as $size) {
					$i++;
					//echo '<p>File '.$i.': '.$all_files["sizes"][$size]["file"].'</p>';
					if (count($all_files["sizes"][$size]["file"]) > 0)
						$files[
							str_replace (
								$attachment_data->filename_base() ,
								$all_files["sizes"][$size]["file"] ,
								$local_file )
						] = str_replace (
										$attachment_data->filename_base() ,
										$all_files["sizes"][$size]["file"] ,
										$remote_file );

				}

		    $results = array();
		    $w3_plugin_cdn->upload($files, false, $results);
		    $response = array(
		        'results' => $results
		    );
				/* //DEBUG
				if ($post_id == 1374) {
					echo '<p>response = ';
					print_r($response);
					echo '</p>';

					echo '<p>files = ';
					print_r($files);
					echo '</p>';			

					echo '<p>w3_plugin_cdn = ';
					print_r($w3_plugin_cdn);
					echo '</p>';

				}
				*/
			}
		}
		/*
			End add by MS
		*/

Sorry to drag up an old thread but have just tried the above code and it doesn’t seem to work. I assume the plugins have both probably had a few updates since this was done.

Any chance of some updated code?

Testing the ThreeWP plugin there are no media added to subsites libraries when broadcasting posts. IMHO, the question is if this is a W3TC issue or ThreeWP Broadcast issue.

W3TC supports wp_insert_attachment etc so there is perhaps something with ThreeWP usage that results in a conflict. GIven that other CDN plugins have issue as well, it might be issue best handled by ThreeWP Broadcast.
