.SH NAME
|
|
curl_formparse - add a section to a multipart/formdata HTTP POST
|
|
.SH SYNOPSIS
|
|
.B #include <curl/curl.h>
|
|
.sp
|
|
.BI "CURLcode curl_formparse(char * " string, " struct HttpPost ** " firstitem,
|
|
.BI "struct HttpPost ** " lastitem ");"

|
.SH DESCRIPTION
|
|
curl_formparse() is used to append sections when building a multipart/formdata
|
|
HTTP POST (sometimes refered to as rfc1867-style posts). Append one section at
|
|
a time until you've added all the sections you want included and then you pass
|
|
the \fI firstitem\fP pointer as parameter to \fBCURLOPT_HTTPPOST\fP.
|
|
\fIlastitem\fP is set after each call and on repeated invokes it should be
|
|
left as set to allow repeated invokes to find the end of the list in a faster
|
|
way. \fIstring\fP must be a zero terminated string abiding to the syntax
|
|
described in a section below
|
|
|
|
The pointers \fIfirstitem\fP and \fIlastitem\fP point to, should both be
|
|
pointers to NULL in the first call to this function. All list-data will be
|
|
allocated by the function itself. You must call \fIcurl_formfree\fP after the
|
|
form post has been done to free the resources again.
|
|
|
|
See example below.
|
|
.SH "FORM PARSE STRINGS"
|
|
The
|
|
.I string
|
|
parameter must be using one of the following patterns. Note that the []
|
|
letters should not be included in the real-life string.
|
|
.TP 0.8i
|
|
.B [name]=[contents]
|
|
Add a form field named 'name' with the contents 'contents'. This is the
|
|
typcial contents of the HTML tag <input type=text>.
|
|
.TP
|
|
.B [name]=@[filename]
|
|
Add a form field named 'name' with the contents as read from the local file
|
|
named 'filename'. This is the typcial contents of the HTML tag <input
|
|
type=file>.
|
|
.TP
|
|
.B [name]=@[filename1,filename2,...]
|
|
Add a form field named 'name' with the contents as read from the local files
|
|
named 'filename1' and 'filename2'. This is identical to the upper, except that
|
|
you get the contents of several files in one section.
|
|
.TP
|
|
.B [name]=@[filename];[type=<content-type>]
|
|
Whenever you specify a file to read from, you can optionally specify the
|
|
content-type as well. The content-type is passed to the server together with
|
|
the contents of the file. curl_formparse() will guess content-type for a
|
|
number of well-known extensions and otherwise it will set it to binary. You
|
|
can override the internal decision by using this option.
|
|
.TP
|
|
.B [name]=@[filename1,filename2,...];[type=<content-type>]
|
|
When you specify several files to read the contents from, you can set the
|
|
content-type for all of them in the same way as with a single file.
|
|
.PP
|
|
.SH RETURN VALUE
|
|
Returns non-zero if an error occurs.
|
|
