Question

I am creating a custom helper in ./application/helpers however i am getting this error

Unable to load requested file helpers/curl_helper

This is the code in my helper file:

    function send(array $request, $url, $method)
{
    //Validating if the required extensions are installed or not
    if( !function_exists('json_encode') )   return false;
    if( !function_exists('curl_init') )     return false;

    //Converting the array into required json format
    $request = json_encode($request);

    //Setting header required for requests
    $header[] = "Content-type: application/json";
    $header[] = "Content-length: ".strlen($request) . "\r\n";

    //If the request method is get append the data into requests header
    if( $method == 'GET' or $method == 'get' )      $header[] = $request;

    //Initializing curl
    $ch = curl_init();
    //Setting curl options for request
    curl_setopt( $ch, CURLOPT_URL, $url);
    curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1 );
    curl_setopt( $ch, CURLOPT_HTTPHEADER, $header );
    curl_setopt( $ch, CURLOPT_CUSTOMREQUEST, $method );

    //If the request method is post add the data we need to enable post 
    //request and define the data in post fields
    if( $method == 'POST' or $method == 'post' ) {
        curl_setopt( $ch, CURLOPT_POST, 1);
        curl_setopt( $ch, CURLOPT_POSTFIELDS, $request);
    }

    //Executing the curl request and storing the result in a variable
    $result = curl_exec( $ch );
    //Closing curl conneciton
    curl_close($ch);

    return json_decode($result);
}

And i am loading it in my library like:

$this->loader =& get_instance();
$this->loader->load->helper('curl');

Tell me where i am doing wrong?

UPDATE:
After trying too many things when i put the function in the same library where i want to use i found that there is an error in the line

curl_setopt( $ch, CURLOPT_HTTPHEADER, $header );

when i comment this line function works fine. I dont know where is the error please help me. And as far as i think this is the reason for loader error.

Well, if you are using the "MY_helpername" then do check if you named the file on your server as “my_helpername“, I don’t know the reason but CI will look for my_helpername.php in helpers folder but not MY_helpername. I have this issue in past and changing the name on my linux box from MY_helpername to my_helpername worked for me.

Hope this helps
