iOS Question FTP stops working after first successful upload

[Vern]

I've been trying to upload 3 files using FTP (iNet 1.2) and no matter what, it only uploads the first file and not the other two. This code works fine in my Android app. If I comment out the FTP code for the first file, the second file uploads but not the third, and so on. Here's the code for uploading the first file:

If File.Exists(filepath, filename) Then
ftp_dest = "/public_html/uploads/" & filename
FTP.UploadFile(filepath, filename, False, ftp_dest)
Log(ftp_dest)
Else
Msgbox("No data to upload (file not found)", "Error")
End If

After seeing this post: https://www.b4x.com/android/forum/threads/ftp-works-only-for-the-first-file.48343/#post-300615
I realize I'm having the same problem. How can I get FTP to work on my iPhone?

Are you handling the UploadCompleted event? What is the output of Log(LastException)?

 

[Vern]

Yes, I am handling the UploadCompleted event. There is no exception and no error message. It looks like everything works, but it doesn't. It appears that all FTP commands (after the first one successfully executes) are being ignored.

Is this server accessible over the internet? If you like you can send me the credentials and I'll check it.

I've tested it and saw this behavior. Once I set PassiveMode to True it worked properly. Please try it.

 

[Vern]

Yes, setting PassiveMode to True fixes the problem. Thanks.

I had the same issue and yes PassiveMode = true fixes the problem

Hi Guys

FTP_UploadProgress, event is not triggered, while FTP_UploadCompleted is working ok.

I would like to know if there is a solution, or at least if I can monitor the upload status to make sure it is still going

Hi,

there is no UploadProgress event in B4i for FTP.

there is no UploadProgress event in B4i for FTP.

Jan, thanks for your reply.
Then, how do I know that an upload is taking place or in progress?

Say you are uploading different size files. Sometimes a 1K file other times 30MB file. How do I know how long to wait for the process (in case things go wrong and I don't get UploadCompleted event)?, or how do I show the user a progress status as indication of how long they should wait for the process to complete?

Thanks again

Hi,

How do I know how long to wait for the process

For now it's not possible to calculate the time for the process.

in case things go wrong and I don't get UploadCompleted event

The UploadCompleted event is always called, to know wheter the upload failed check the Success parameter.

The best solution is to show a progress indicator when you start the upload and hide it in the UploadCompleted event.

Thanks Jan for the advise.
I am already doing it this way. The only thing I don't like about it, is that there is no indication for the user about the estimated time ( or the progress in general)

Thanks again
