Upload
An upload control allows the user to select files from the local file system and upload them to the server.
It supports drag and drop, multiple file selection.
A server-side uiSet (not a scope uiSet) must be executed to allow the upload and specify the upload path:
uiSet("<object ID>", "path", "<upload path>")
-
name: the object ID
-
upload path: the path where the uploaded files are saved, relative to the HSYCO main directory
When the upload is completed, a command is generated with:
-
name: the object ID
-
parameter: the uploaded file name, including the extension
Attributes
Common
ID
Sets the object's ID.
The ID identifies the object and is used to reference it in UISet actions, allowing to change its attributes dynamically.
The ID is not unique, it can be shared among multiple objects to quickly change a common attribute.
IDs can't be changed with a UISet action, but they can have a Value Binding assigned to them. Value Bindings on IDs allow an object to be dinamically attached to a set of attribute values.
E.g. the following Value Binding switches the ID of the object between mybutton1 and mybutton2 based on the value of the UISet button.address:
Value binding:
="mybutton" + ui('button', 'address')
UISet:
UISet('button', 'address', '1') switches the ID to mybutton1
UISet('button', 'address', '2') switches the ID to mybutton2
Position and Size
Position
Sets the object's position.
The default value is: x0y0.

Path
Specifies the path where uploaded files are saved. If this attribute is not set, the upload has no effect (no files saved on the server).
For security reasons, this UISET must be executed on the server-side code (EVENTS, JavaScript or Java). A client-side UISET would be ignored.
This attribute is live. It can't be set from the Project Editor, it needs to be set dynamically with a UISet.
