Append one section at -a time until you've added all the sections you want included and then you pass -the \fIfirstitem\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 faster. - -After the \fIlastitem\fP pointer follow the real arguments. (If the following -description confuses you, jump directly to the examples): - -\fBCURLFORM_COPYNAME\fP or \fBCURLFORM_PTRNAME\fP followed by a string is used -for the name of the section. Optionally one may use \fBCURLFORM_NAMELENGTH\fP -to specify the length of the name (allowing null characters within the -name). All options that use the word COPY in their names copy the given -contents, while the ones with PTR in their names simply points to the (static) -data you must make sure remain until curl no longer needs it. - -The four options for providing values are: \fBCURLFORM_COPYCONTENTS\fP, -\fBCURLFORM_PTRCONTENTS\fP, \fBCURLFORM_FILE\fP, or \fBCURLFORM_FILECONTENT\fP -followed by a char or void pointer (allowed for PTRCONTENTS). - -\fBCURLFORM_FILECONTENT\fP does a normal post like \fBCURLFORM_COPYCONTENTS\fP -but the actual value is read from the filename given as a string. - -Other arguments may be \fBCURLFORM_CONTENTTYPE\fP if the user wishes to -specify one (for FILE if no type is given the library tries to provide the -correct one; for CONTENTS no Content-Type is sent in this case). - -For \fBCURLFORM_PTRCONTENTS\fP or \fBCURLFORM_COPYNAME\fP the user may also -add \fBCURLFORM_CONTENTSLENGTH\fP followed by the length as a long (if not -given the library will use strlen to determine the length). - -For \fBCURLFORM_FILE\fP the user may send multiple files in one section by -providing multiple \fBCURLFORM_FILE\fP arguments each followed by the filename -(and each FILE is allowed to have a CONTENTTYPE). - -Another possibility to send single or multiple files in one section is to use -\fBCURLFORM_ARRAY\fP that gets a struct curl_forms array pointer as its -value. Each structure element has a CURLformoption and a char pointer. For the -options only \fBCURLFORM_FILE\fP, \fBCURLFORM_CONTENTTYPE\fP, and -\fBCURLFORM_END\fP (that is used to determine the end of the array and thus -must be the option of the last and no other element of the curl_forms array) -are allowed. The effect of this parameter is the same as giving multiple -\fBCURLFORM_FILE\fP options possibly with \fBCURLFORM_CONTENTTYPE\fP after or -before each \fBCURLFORM_FILE\fP option. - -Should you need to specify extra headers for the form POST section, use -\fBCURLFORM_CONTENTHEADER\fP. This takes a curl_slist prepared in the usual way -using \fBcurl_slist_append\fP and appends the list of headers to those Curl -automatically generates for \fBCURLFORM_CONTENTTYPE\fP and the content -disposition. The list must exist while the POST occurs, if you free it before -the post completes you may experience problems. - -The last argument in such an array must always be \fBCURLFORM_END\fP. - -The pointers \fI*firstitem\fP and \fI*lastitem\fP should both be pointing 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. - -This function will copy all input data except the data pointed to by the -arguments after \fBCURLFORM_PTRNAME\fP and \fBCURLFORM_PTRCONTENTS\fP and keep -its own version of it allocated until you call \fIcurl_formfree\fP. When -you've passed the pointer to \fIcurl_easy_setopt\fP, you must not free the -list until after you've called \fIcurl_easy_cleanup\fP for the curl handle. If -you provide a pointer as an arguments after \fBCURLFORM_PTRNAME\fP or -\fBCURLFORM_PTRCONTENTS\fP you must ensure that the pointer stays valid until -you call \fIcurl_form_free\fP and \fIcurl_easy_cleanup\fP. - -See example below. -.SH RETURN VALUE -Returns non-zero if an error occurs. -.SH EXAMPLE -.nf - - struct HttpPost* post = NULL; - struct HttpPost* last = NULL; - char namebuffer[] = "name buffer"; - long namelength = strlen(namebuffer); - char buffer[] = "test buffer"; - char htmlbuffer[] = "<HTML>test buffer</HTML>"; - long htmlbufferlength = strlen(htmlbuffer); - struct curl_forms forms[3]; - char file1[] = "my-face.jpg"; - char file2[] = "your-face.jpg"; - /* add null character into htmlbuffer, to demonstrate that - transfers of buffers containing null characters actually work - */ - htmlbuffer[8] = '\\0'; - - /* Add simple name/content section */ - curl_formadd(&post, &last, CURLFORM_COPYNAME, "name", - CURLFORM_COPYCONTENTS, "content", CURLFORM_END); - - /* Add simple name/content/contenttype section */ - curl_formadd(&post, &last, CURLFORM_COPYNAME, "htmlcode", - CURLFORM_COPYCONTENTS, "<HTML></HTML>", - CURLFORM_CONTENTTYPE, "text/html", CURLFORM_END); - - /* Add name/ptrcontent section */ - curl_formadd(&post, &last, CURLFORM_COPYNAME, "name_for_ptrcontent", - CURLFORM_PTRCONTENTS, buffer, CURLFORM_END); - - /* Add ptrname/ptrcontent section */ - curl_formadd(&post, &last, CURLFORM_PTRNAME, namebuffer, - CURLFORM_PTRCONTENTS, buffer, CURLFORM_NAMELENGTH, - namelength, CURLFORM_END); - - /* Add name/ptrcontent/contenttype section */ - curl_formadd(&post, &last, CURLFORM_COPYNAME, "html_code_with_hole", - CURLFORM_PTRCONTENTS, htmlbuffer, - CURLFORM_CONTENTSLENGTH, htmlbufferlength, - CURLFORM_CONTENTTYPE, "text/html", CURLFORM_END); - - /* Add simple file section */ - curl_formadd(&post, &last, CURLFORM_COPYNAME, "picture", - CURLFORM_FILE, "my-face.jpg", CURLFORM_END); - - /* Add file/contenttype section */ - curl_formadd(&post, &last, CURLFORM_COPYNAME, "picture", - CURLFORM_FILE, "my-face.jpg", - CURLFORM_CONTENTTYPE, "image/jpeg", CURLFORM_END); - - /* Add two file section */ - curl_formadd(&post, &last, CURLFORM_COPYNAME, "pictures", - CURLFORM_FILE, "my-face.jpg", - CURLFORM_FILE, "your-face.jpg", CURLFORM_END); - - /* Add two file section using CURLFORM_ARRAY */ - forms[0].option = CURLFORM_FILE; - forms[0].value = file1; - forms[1].option = CURLFORM_FILE; - forms[1].value = file2; - forms[2].option = CURLFORM_END; - - /* no option needed for the end marker */ - curl_formadd(&post, &last, CURLFORM_COPYNAME, "pictures", - CURLFORM_ARRAY, forms, CURLFORM_END); - /* Add the content of a file as a normal post text value */ - curl_formadd(&post, &last, CURLFORM_COPYNAME, "filecontent", - CURLFORM_FILECONTENT, ".bashrc", CURLFORM_END); - /* Set the form info */ - curl_easy_setopt(curl, CURLOPT_HTTPPOST, post); - -.SH "SEE ALSO" -.BR curl_easy_setopt "(3), " -.BR curl_formparse "(3) [deprecated], " -.BR curl_formfree "(3)" -.SH BUGS -Surely there are some, you tell me! - |
