Uploading a php-formhandler after changing the form does not work

[cg68]

Hallo,

I have a curious problem. Maybe only for me?

When uploading my webside including a simple contact-form and the form-handler.php file to send the Datas to my email address, everything works fine.

But when I upload the form-handler.php once again, the contact form produces an error!

It doesn't matter wether the uploaded form-handler.php is changed or not!

I use a MAC (OS: Sierra), Dreamweaver CC, FTP, passive mode, Port 21, no Problems to connect my PC via FTP to the server with dreamweaver.

When I use my old Windows PC with an FTP-Programm to overwrite the form-handler.php - I had uploaded with dreamweaver before - everything is OK again!

Sorry, I have no exercise of writing englisch.

This error makes my crazy. I cant't use my old windows PC to upload the PHP files every time!

Can you give me a hint how to change the way dreamweaver transfers data via FTP  to the remote server?

Thank you very much for reading,

Christian

Windows and Macs use different Line Breaks.    CR LF = Win, CR or LF =  Mac/Unix. 

Using a Windows PC and a Mac to transfer same files up & down from server can introduce conflicts in the line beaks which might explain the script errors.

Hello Nany OShea,

thank you very much for your quick very helpful answer.

Switching the preferences in DW running on a MAC to "CR LF (Windows)"-Format fixes the problem.

Is this logical? Never mind - it works!

I the meantime I made serveral changes to my form-handler.php and the form runs even after uploading it on the server.

Because the problem belongs to the Server I use - it might be interesting for other users - my webside is running with a Linux server.

So using Mac, Linefeed as "CR LF (Windows)", as descibed by Nancy, with a Linux server seems to be the right combination.

Thanks,

Christian
