#50060 [Bgs]: "failed creating formpost data" if post array value starts with '@'

ID: 50060 Updated by: scottmac@php.net Reported By: bugs dot php dot net at sgerrand dot com Status: Bogus Bug Type: cURL related Operating System: Linux (Ubuntu x86_64 2.6.31-14) PHP Version: 5.2.11 New Comment: -d is for the whole data, what we really have here is -F for formdata. curl -F 'key=@value' http://www.php.net/ Previous Comments: ------------------------------------------------------------------------ [2009-11-03 10:44:13] bugs dot php dot net at sgerrand dot com Please refer to the documentation for curl_setopt() - http://php.net/curl_setopt CURLOPT_POSTFIELDS The full data to post in a HTTP "POST" operation. To post a file, prepend a filename with @ and use the full path. This can either be passed as a urlencoded string like 'para1=val1&para2=val2&...' or as an array with the field name as key and field data as value. If value is an array, the Content-Type header will be set to multipart/form-data. The case I have logged is when data to be posted using this option is an array which happens to have a value that starts with '@', as per the example. This edge case is being caused by the function used to create the form data to pass to cURL. I would note that the cURL command line client on any POSIX system can perform this without issue - i.e.: curl -d 'key=@value' http://www.php.net/ ------------------------------------------------------------------------ [2009-11-03 10:18:06] scottmac@php.net @ has a special meaning with cURL and takes the contents of the file. ------------------------------------------------------------------------ [2009-11-03 07:29:36] bugs dot php dot net at sgerrand dot com Description: ------------ PHP's cURL library dies returning the error message "failed creating formpost data" when trying to use an array that contains a value starting with '@'. If the array is changed to a string in URL encoded like format, the problem does not occur. Reproduce code: --------------- <?php $url = 'http://www.php.net'; $postData = array('key' => '@value'); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, $postData); if (! curl_exec($ch) ) print 'cURL error: ' . curl_error($ch); else print "cURL success"; curl_close($ch); ?> Expected result: ---------------- cURL success Actual result: -------------- cURL error: failed creating formpost data ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=50060&edit=1
