Reading a cURL post request. - El Forum - 11-30-2009

Hello I am trying to send a POST request from one CI project to another. I have written some code that sends a POST request with cURL. I have put a proxy in the middle and I can see the POST (with the HTTP parameters passed fine) request getting through fine. But on the second project I try to read the POST variable by first checking if there is a post

Code:
public function mymethod()

{

        if($_POST) echo "POST";

        else echo "NOT POST";

}

but it always returns "NOT POST".

In the first project I send a request by doing

Code:
$header[] = 'Content-type: text/plain';

        $ch=curl_init();

        curl_setopt($ch, CURLOPT_URL, 'http://myserver/mycontroller/mymethod');

        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);

        curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 6.0; en-GB; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3 GTB6');

        curl_setopt($ch, CURLOPT_POST, true);

        curl_setopt($ch, CURLOPT_HTTPHEADER, $header);

        curl_setopt($ch, CURLOPT_POSTFIELDS, "comment=$data");

        curl_setopt($ch, CURLOPT_TIMEOUT, 120);

        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

//        curl_setopt($ch, CURLOPT_PROXY, "127.0.0.1");

//        curl_setopt($ch, CURLOPT_PROXYPORT, 15000); 

        $result = curl_exec($ch);

        curl_close($ch);

        echo $result;

Is there something I am missing? I'd appreciate any help.

Regards

Panos

Ps. I know there are a couple of cURL libraries I can use, but I would like to use my own code.

That's exactly what it should be doing. Smile

You see, CodeIgniter clears out the $_GET and $_POST arrays after it gathers the values and sanitizes them.

It's part of it's beauty. The $_POST array is available to you to use through the Input Class in the User Guide.

Try:

Code:
$this->input->post('fieldname');

You'll find it works quite nicely. You can simply check against that to see if a value's been sent. No need to check for value and ISSET(), as the class does that for you.

Good luck with you project!

Hello jeremygimbel, thanks for your reply. Unfortunatelly even if I do

Code:
echo $this->input->post('comment');

this returns nothing back. It behaves like the parameter is not set at all. Any other ideas? There must be something that I'm missing.

After some trial and error attempts I found the problem. The content type should have been form-urlencoded

Code:
Content-type: application/x-www-form-urlencoded
