Is there a way to access to a document field and assign “Extensions to allow” Attribute?

I have try do it like this

In field Attributes:
I have set “Extensions to allow” to {myExt}
In form onload event :
{myExt}=?txt;.txt? ;

but it gives error message ?invalid file type? when i try to upload a txt file.

What you might try (as I think you are using a file upload) is to set a global variable in the ‘extensions to allow’ field, i.e. [myext].
Then set the global to your extensions [myext]=‘txt;pdf’;

This assignment needs to be done before using the field so an onscriptinit would do.

there is such option in the field setting itself!

#4

Yes there is. Just choose the right fieldtype. (upload)

This doesn’t work anymore. Using a global returns an error. Any other suggestions?

Report to SC and hope for the best I’m afraid. They might have changed it, but it also could be a simple bug.
