C++ web programming, textarea via POST

ewigej (2)
Hello guys!

This is my first forum participation experience, so please be nice!:)

I am working on a small program which is going to prioritize 20 sentences according to the degree of importance.

I want to do it via C++ via Web interface

right now'm trying to send <textarea> 20 sentences to some .cgi file to make it stored in some .txt file.

difficulty: cannot send anything via post, it says 0 bytes have been sent.
what do I do?

here's my script code:


1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23
24
25
26
27
28
29
 
#include <stdio.h>
#include <stdlib.h>

void main(void) {

  char *RemoteAddr = getenv("REMOTE_ADDR");
  char *ContentLength = getenv("CONTENT_LENGTH");
  char *QueryString = getenv("QUERY_STRING");

  int NumBytes = atoi(ContentLength);

  char *Data = (char *)malloc(NumBytes + 1);

  fread(Data, 1, NumBytes, stdin);

  Data[NumBytes] = 0;

  printf("Content-type: text/html\n\n");

  printf("<html><body>");
  printf("<h1>Yo guys, what's up!?</h1>");
  printf("ip address: %s<br>",RemoteAddr);
  printf("Number of bytes: %d<br>",NumBytes);
  printf("20 sentences: %s<br>",Data);
  printf("check if at least URL thing working: %s",
    QueryString);

  printf("</body></html>");
}



here's what I get as the output:

1
2
3
4
5
 
Yo guys, what's up!?
ip address: 127.0.0.1
Number of bytes: 0
20 sentences:
check if at least URL thing working: working_HARD!

I do type text into the form.. I wonder why there's no bytes? and no data has been sent?

Well...what you wrote above is in C not in C++, as far as I know. On the other hand, I see in your code a combination of HTML and C, actually, something that I've never seen before. I didn't actually knew that can exist something like this.

thank you for the reply CosminNTG!

yeah, I know:) not many people do that, I wanna try C/C++ in Web

i don't know, I go look some other forums may be

thanks again CosminNTG!

But C or C++ are not suitable for web programming. Those are not web-programming languages, they aren't even scripting languages. Try to do it in Java or PHP, you'll definitely do it!
