PHP Class Prado\Web\UI\ActiveControls\TActiveFileUpload

TActiveFileUpload displays a file upload field on a page. Upon postback, the text entered into the field will be treated as the name of the file that will be uploaded to the server. The property {@link getHasFile HasFile} indicates whether the file upload is successful. If successful, the file may be obtained by calling {@link saveAs} to save it at a specified place. You can use {@link getFileName FileName}, {@link getFileType FileType}, {@link getFileSize FileSize} to get the original client-side file name, the file mime type, and the file size information. If the upload is not successful, {@link getErrorCode ErrorCode} contains the error code describing the cause of failure. TActiveFileUpload raises {@link onFileUpload OnFileUpload} event if a file is uploaded (whether it succeeds or not). TActiveFileUpload actually does a postback in a hidden IFrame, and then does a callback. This callback then raises the {@link onFileUpload OnFileUpload} event. After the postback a status icon is displayed; either a green checkmark if the upload is successful, or a red x if there was an error. TActiveFileUpload needs either an application level cache or a security manager to work securely.
