Using Curl in CodeIgniter : How to send data using post method - php

Question

Not going to succeed when trying to send data using post method. Never used it before.
This is code of executing curl:
$url = LICENSE_URL."validate_system_key/validate_key/";
//url-ify the data for the POST
$data['system_key']='A8Z0-X1N7-S1V2-Y1I5';
$data['domain']='http://example.com';
$fields_string = '';
foreach($data as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
$fields_string = rtrim($fields_string,'&');
//open connection
$ch = curl_init();
//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_POST,count($data));
curl_setopt($ch,CURLOPT_POSTFIELDS,$fields_string);
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,10); # timeout after 10 seconds, you can increase it
//curl_setopt($ch,CURLOPT_HEADER,false);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); # Set curl to return the data instead of printing it to the browser.
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
//execute post
$result = curl_exec($ch);
//close connection
curl_close($ch);
$result=json_decode($result,TRUE);
And this is the Code On Client Url:
public function validate_key(){
$system_key=$_POST['system_key'];
$domain=$_POST['domain'];
$result['error']=3;
echo json_encode($result);
}
Note: When I am not using POST method (sending data through url) evrything is fine. Its all about POST method, not getting the mistake! Any kind of help will be appreciated! Thanks.

Answer 1

Use array instead of String in data passed to string like below:
foreach($data as $key=>$value) {
$data[$key] = $value;
}
curl_setopt($ch,CURLOPT_POSTFIELDS,$data);
I hope this will work.
