Connect to PHP website, and pass params

I have a string, which I'd like to pass to a PHP webpage, in the form of either POST or GET data (whichever one is easiest).

e.g.

   http://www.mydomain.com/myscript.php?getVar=mystr

Or whatever..

So that my PHP script can then parse the data, and store it on my web server.

Any ideas?

Thanks

I'd recommend using a library like libcurl for posting data: http://www.curl.haxx.se

There are tutorials on the site for the basic usage of curl, but if you want a sample on how to post data:

int VFinder::Login(){
        m_page.clear();
        string field;
        string battle("http://www.kingsofchaos.com/battlefield.php");
        if(!m_login){
                if(m_srank>0){
                        ostringstream converter;
                        converter << m_srank;
                        battle.append("?start=");
                        battle.append(converter.str());
                }
                field.assign("username=&pword=&usrname=");
                field.append(m_user+"&uemail="+m_email+"&peeword="+m_pword+"&hash=");

                curl_easy_setopt(m_handle, CURLOPT_URL, "http://www.kingsofchaos.com/login.php");
                curl_easy_setopt(m_handle, CURLOPT_WRITEFUNCTION, VFinder::store);
                curl_easy_setopt(m_handle, CURLOPT_COOKIEJAR, "cookie.txt");
                curl_easy_setopt(m_handle, CURLOPT_POST, true);
                curl_easy_setopt(m_handle, CURLOPT_POSTFIELDS, field.c_str());
                curl_easy_setopt(m_handle, CURLOPT_POSTFIELDSIZE, field.size());
                curl_easy_perform(m_handle);
                m_login = true;
        }

        curl_easy_setopt(m_handle, CURLOPT_POST, false);
        curl_easy_setopt(m_handle, CURLOPT_URL, battle.c_str());
        curl_easy_perform(m_handle);
        return 0;
}

Feeling lazy right now :P so i just copy pasted code from my application that i made

Right, I found a POST example:


#include <stdio.h>
#include <curl/curl.h>

int main(void)
{
  CURL *curl;
  CURLcode res;

  char *postthis="moo mooo moo moo";

  curl = curl_easy_init();
  if(curl) {
    curl_easy_setopt(curl, CURLOPT_URL, "http://mydomain.com/page.php");
    curl_easy_setopt(curl, CURLOPT_POSTFIELDS, postthis);

    /* if we don't provide POSTFIELDSIZE, libcurl will strlen() by
       itself */
    curl_easy_setopt(curl, CURLOPT_POSTFIELDSIZE, strlen(postthis));

    res = curl_easy_perform(curl);

    /* always cleanup */
    curl_easy_cleanup(curl);
  }
  return 0;
}


And I've copied the curl/.. lib into Dev-C++'s include folder, and have pointed my the directories within my Compiler Options to it, but am getting linker errors:

Hm, bloody hell. I didn't realise... everything within the 'Include' folder within the Libcurl download are mere header files!

I'm not sure what IDE you're using but you have to find a way to make it link to the curl library (you have to add "-lcurl" there).

You can use HTTP functionality.
i.e. u can define your HTTP handlers. e.g.

Add #include <afxinet.h>    // MFC Internet support

HINTERNET     m_hInternetSession;
HINTERNET     m_hHttpConnection;
 HINTERNET     m_hHttpFile;

//Open internet session.
ASSERT(m_hInternetSession == NULL);
m_hInternetSession = ::InternetOpen(AfxGetAppName(), INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, 0);  

You can visit the link to  have brief idea of rest of the functionality:
