NAME

6       CURLOPT_HTTPPOST - multipart formpost content
7

SYNOPSIS

9       #include <curl/curl.h>
10
11       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HTTPPOST,
12                                 struct curl_httppost *formpost);
13

DESCRIPTION

15       This option is deprecated. Use CURLOPT_MIMEPOST(3) instead.
16
17       Tells  libcurl  you  want a multipart/formdata HTTP POST to be made and
18       you instruct what data to pass on to the server in the  formpost  argu‐
19       ment.   Pass a pointer to a linked list of curl_httppost structs as pa‐
20       rameter.  The easiest way to create such a list, is  to  use  curl_for‐
21       madd(3) as documented. The data in this list must remain intact as long
22       as the curl transfer is alive and is using it.
23
24       Using POST with HTTP 1.1 implies the use of  a  "Expect:  100-continue"
25       header.  You can disable this header with CURLOPT_HTTPHEADER(3).
26
27       When setting CURLOPT_HTTPPOST(3), it will automatically set CURLOPT_NO‐
28       BODY(3) to 0.

EXAMPLE

37       /* Fill in the file upload field. This makes libcurl load data from
38          the given file name when curl_easy_perform() is called. */
39       curl_formadd(&formpost,
40                    &lastptr,
41                    CURLFORM_COPYNAME, "sendfile",
42                    CURLFORM_FILE, "postit2.c",
43                    CURLFORM_END);
44
45       /* Fill in the filename field */
46       curl_formadd(&formpost,
47                    &lastptr,
48                    CURLFORM_COPYNAME, "filename",
49                    CURLFORM_COPYCONTENTS, "postit2.c",
50                    CURLFORM_END);
51
52       /* Fill in the submit field too, even if this is rarely needed */

54                    &lastptr,
55                    CURLFORM_COPYNAME, "submit",
56                    CURLFORM_COPYCONTENTS, "send",
