[Cppcms-users] cppcms::widgets::file is always not set

From: CN <cn...@gr...> - 2010-10-31 09:25:20

Basing on ./examples/forms/*, I use cppcms::widgets::file as follows:

   cppcms::widgets::text name;
   cppcms::widgets::file uploaded_file;
   cppcms::widgets::submit submit;
   name.non_empty();
   uploaded_file.non_empty();

This is called as usual:

   c.info.load(context());

My problem is that

   c.info.validate()

always returns false. Widget "name" does have been fed with string, but  
"uploaded_file" is always not set:

   std:cout << c.info.uploaded_file.value()->filename() << std::endl;

raises exception "File was not loaded".

Calling method cppcms::widgets::file::load() does not feed anything to  
itself, either:

   c.info.uploaded_file.load(context());

Helps are much welcome!

Best Regards,
CN

Two points:

1. Make sure you add the file widget to the form by using:

      *this + uploaded_file
   or    


      add(uploaded_file)

2. Make sure you use enctype="multipart/form-data" in your form. i.e.

   <form method="post" action="URL" enctype="multipart/form-data" >
   <% form as_p info %>
   </form>

   Because you can't upload file using regular "post" using 
   default encoding "application/x-www-form-urlencoded"

I have added everything you suggested. Now I get "503 - Service Not  
Available". My cppCMS application appears to have failed to catch the  
posted form sent from browser. My problem perhaps fall in the realm of web  
server administration instead of cppCMS, but helps are greatly appreciated.

This comes from Opera's source inspection:

<html>
     <body>
     <h1>Upload your file</h1>
     <form method="post" action="http://localhost/upload"  
enctype="multipart/form-data" accept-charset="UTF-8">
     <p>Name:&nbsp;<span class="cppcms_form_input"><input type="text"  
name="_1"  ></span></p>
<p><span class="cppcms_form_input"><input type="file" name="_2"   
></span></p>
<p><span class="cppcms_form_input"><input type="submit" name="_3"  
value="Upload"  ></span></p>

     </form>
   </body>
<html>


No error is logged by my cppCMS application. The following two lighttpd  
log entries appear after the web page is opened by browser:

2010-11-01 13:35:30: (mod_fastcgi.c.2979) got proc: pid: 0 socket:  
unix:/tmp/cppcms-socket load: 1
2010-11-01 13:35:30: (mod_fastcgi.c.1508) released proc: pid: 0 socket:  
unix:/tmp/cppcms-socket load: 0

The following entries are added to lighttpd log after I submit the form in  
browser.

2010-11-01 13:35:38: (mod_fastcgi.c.2979) got proc: pid: 0 socket:  
unix:/tmp/cppcms-socket load: 1
2010-11-01 13:35:38: (mod_fastcgi.c.3041) write failed: Broken pipe 32
2010-11-01 13:35:38: (mod_fastcgi.c.1508) released proc: pid: 0 socket:  
unix:/tmp/cppcms-socket load: 0

Privileges look fine, too:

# ls -l /tmp/cppcms-socket
srwxrwxrwx 1 www-data www-data 0 2010-11-01 12:39 /tmp/cppcms-socket
