Wordpress PHP Execution Plugin

The PHP Execution Plugin is a Wordpress plugin which allows users to write php code inside of their posts and pages. Embedded php code will be executed when the post is shown. In doing so, the plugin offers the possibility to utilize dynamic content inside of posts.

Probably you might say, that there are already plugins that do the same!
So why another plugin that executes php code?

Well this plugin integrates well with Wordpress’ visual editor as the picture above shows. So in contrast to other plugins, you don’t need to turn off the visual editor in order to edit your php code.

Flex FileUpload Component

What we’ve got here is a FileUpload component for Flex which utilizes the new FileReference.load method available since Flash Player 10 to support uploading of large files.
As a lot of providers choose a very small size for their PHP ini settings of upload_max_filesize and post_max_size, uploading files bigger than 2mb is often not supported. This can be very annoying if you like to upload mp3 or video files, which easily can exceed the maximum accepted file size. In this case you normally have to go with an FTP client.

Uploading large files

If supported by the client’s Flash Player this upload component utilizes the new FileReference.load method to load the file into the ram of the client computer at first. Once loaded the file data can be read via the data property of the FileReference object. It is now possible to extract chunks of the loaded file data and upload those chunks to the server separately. This way the upload-data won’t exceed the maximum accepted post data of the server as the chunks used are a lot smaller. On the server side, a php script is joining the chunks together to the original file.

Resuming Uploads

Prior to uploading the uploader also calculates an adler32 checksum of the file data. This checksum is used to check if a partially uploaded file already exists on the server and an upload operation can be resumed.
