NAME

       CURLOPT_HTTPPOST - multipart formpost content

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HTTPPOST,
                                 struct curl_httppost *formpost);

DESCRIPTION

       This option is deprecated. Use CURLOPT_MIMEPOST(3) instead.

       Tells  libcurl  you  want  a multipart/formdata HTTP POST to be made and you instruct what
       data to pass on to the server in the formpost argument.  Pass a pointer to a  linked  list
       of  curl_httppost  structs as parameter.  The easiest way to create such a list, is to use
       curl_formadd(3) as documented. The data in this list must remain intact  as  long  as  the
       curl transfer is alive and is using it.

       Using  POST  with  HTTP  1.1  implies the use of a "Expect: 100-continue" header.  You can
       disable this header with CURLOPT_HTTPHEADER(3).

       When setting CURLOPT_HTTPPOST(3), libcurl automatically sets CURLOPT_NOBODY(3) to 0.

DEFAULT

       NULL

PROTOCOLS

       This functionality affects http only

EXAMPLE

       int main(void)
       {
         struct curl_httppost *formpost;
         struct curl_httppost *lastptr;

         /* Fill in the file upload field. This makes libcurl load data from
            the given file name when curl_easy_perform() is called. */
         curl_formadd(&formpost,
                      &lastptr,
                      CURLFORM_COPYNAME, "sendfile",
                      CURLFORM_FILE, "postit2.c",
                      CURLFORM_END);

         /* Fill in the filename field */
         curl_formadd(&formpost,
                      &lastptr,
                      CURLFORM_COPYNAME, "filename",
                      CURLFORM_COPYCONTENTS, "postit2.c",
                      CURLFORM_END);

         /* Fill in the submit field too, even if this is rarely needed */
         curl_formadd(&formpost,
                      &lastptr,
                      CURLFORM_COPYNAME, "submit",
                      CURLFORM_COPYCONTENTS, "send",
                      CURLFORM_END);

         CURL *curl = curl_easy_init();
         if(curl) {
           curl_easy_setopt(curl, CURLOPT_HTTPPOST, formpost);
           curl_easy_perform(curl);
           curl_easy_cleanup(curl);
         }
         curl_formfree(formpost);
       }

DEPRECATED

       Deprecated in 7.56.0.

RETURN VALUE

       Returns CURLE_OK if HTTP is enabled, and CURLE_UNKNOWN_OPTION if not.
