Upload

An item that allows uploading multiple files and tracking the progress of individual file upload.

Common attributes:

• className - (string) the user-defined css class for the item
• name - (string) the identification name. Used for referring to the item
• inputHeight - (integer or auto) the height of the item. The default value is auto
• inputWidth - (integer or auto) the width of the item. The default value is auto
• offsetLeft - (integer) sets the left relative offset of the item
• offsetTop - (integer) sets the top relative offset of the item
• hidden - (boolean) hides/shows the item. The default value - false (the item is shown)
• disabled - (boolean) disables/enables the item. The default value - false

Uploader-related attributes:

• mode - (html5, html4, flash) allows you to manually set the mode in use. Beware, once you set the mode manually, the control will work in this mode permanently independently on the browser you use
• titleScreen - (boolean) defines whether the initial screen (when no files are selected) must be displayed. The default value - true
• titleText - (string) the text of the initial screen. The default value - ”Drag-n-Drop files here or click to select files for upload”
• autoStart - (boolean) defines whether files must be immediately loaded after selecting. The default value - false
• autoRemove - (boolean) defines whether files must be removed from the item after complete downloading. The default value - false

URL attributes:

• url - (string) the path to the server-side script (relative to the index file) which will parse the requests received from the uploader. Used in the html5/html4 modes
• swfPath - (string) the path to the client flash script file relative to the index file
• swfUrl - (string) the path to the server script file (relative to the client flash script file) which will parse the requests. Used in the flash mode

The control can work in 3 modes:

1. html5 (multiple files selecting, tracking the progress, loading by Ajax, d-n-d for selecting files)
2. flash (multiple files selecting, tracking the progress, loading by Flash)
3. html4 (works as a standard HTML input upload control)

By default, the item uses the html5 mode, then flash if html5 isn't supported. If both html5 and flash aren't supported - html4.

For providing loading, the control uses a script that gets files to load. The same script is used in all modes but with slight differences.

Let's assume you have the folders tree as in:

where

• samples/07_uploader/01_basic_init.html - the index file (currently selected).
• samples/07_uploader/php/dhtmlxform_item_upload.php - the server script we use.

For html5/html4 modes it's quite enough to set the url parameter:

• url - the path to the server script file dhtmlxform_item_upload.php relative to the index file 01_basic_init.html, in our case the path will be “php/dhtmlxform_item_upload.php”

For the flash mode you must specify 2 parameters: swfPath, swfUrl

• swfPath - the path to the client flash script file uploader.swf relative to the index file 01_basic_init.html, in our case the path will be ”../../codebase/ext/uploader.swf”
• swfUrl - the path to the server script file dhtmlxform_item_upload.php relative to the client flash script file uploader.swf, in our case the path will be ”../../samples/07_uploader/php/dhtmlxform_item_upload.php”

formdata = [{
        type: "upload",
        name: "myFiles",
        url: "php/dhtmlxform_item_upload.php",
        swfPath: "../../codebase/ext/uploader.swf",
        swfUrl: "../../samples/07_uploader/php/dhtmlxform_item_upload.php"
}]

The control has a number of self-specific methods.
A full list of them you can find here - API Reference: uploader-related methods.
The related to the control events can be found here.

Of course, you can carry on using any of common dhtmlxForm methods as well.
