Wt

Hi Jean,
I actually can't reproduce this and I'm not sure what would cause the difference. Your system seems quite old, perhaps that has something to do with it. Other than that I don't really know.

Apart from that, your code mentions fu->setFileTextSize(50); // Set the maximum file size to 50 kB.. This method just determines the size of the input-field. To configure max upload size, check out <max-request-size> in wt_config.xml. The default is 128kB, so I don't think that's what is causing your problem.

Hi,

I experienced the same thing on 4.6.3.

When I apply the following:

diff --git a/src/Wt/WFileUpload.C b/src/Wt/WFileUpload.C
index 6b7f10bfdab1..b3ea4e3169f6 100644
--- a/src/Wt/WFileUpload.C

+    }
+#endif

     if (!request.tooLarge())
       if (!files.empty() || request.getParameter("data"))

then the uploaded signal is emitted and my log reads:

So for some reason the name value ( "data" ) in the form-data is double double-quoted.
