Posting multidimensional array with PHP and CURL
arrays, curl, php, post
Solution
You'd have to build the POST string manually, rather than passing the entire array in. You can then override curl's auto-chose content header with:
curl_setopt($c, CURLOPT_HTTPHEADER, array("Content-type: multipart/form-data"));
Serializing/json-ifying would be easier, but as you say, you have no control over the receiving end, so you've got a bit of extra work to do.
Problem
I'm having trouble posting form data via CURL to a receiving PHP script located on a different host. I get an `Array to string conversion` error This is `print_r` of the array I'm posting: ``` Array ( [name] => Array ( [0] => Jason [1] => Mary [2] => Lucy ) [id] => 12 [status] => local [file] => @/test.txt ) ``` This is the line the error occurs on: ``` curl_setopt($this->ch, CURLOPT_POSTFIELDS, $post); ``` The third argument must be an array because I need the `Content-Type` header to be set to `multipart/form-data` as I am sending a file via this same array, therefore I cannot convert the array to a query string or use `http_build_query()`. Also I do not have access to the code on the receiving host so I cannot serialize and unserialize the array. I'm assuming that the value of the name key being an array is the cause for this error, I'm also assuming that `CURLOPT_POSTFIELDS` doesn't support multidimensional arrays. Is there any other way around this or am I doomed? Thanks in advance!
