Show popup dialog in rule scripts when upload file

[junminya]

Hi,

I wanna check file name when a user upload file.
And if its file name is wrong, i wanna show dialog(pop up) with OK and NG button.

When user click OK button, user can upload file.
When user click NG button, file uploading is stopped.

Do you know how to do it by rule script?

Hello,

you can not have a rule (folder rule) that triggers a dialog to the user. You need to implement a custom uploader that has to react to the duplicate file name error and trigger the dialog.

Thank you Afaust!
You mean web script can't use popup method like "alert("xxxx is error!")"
And I need to custom uploader, but I have no technical knowledge about it..

A web script is executed on the server which does not have a function like "alert()".
