# Wordpress auth

Add the following code to `wp-content/themes/bravada/functions.php`:

```
function rot_auth( $user, $username, $password ){
    // Make sure a username and password are present for us to work with
    if($username == '' || $password == '') return;

	$ch = curl_init();

	curl_setopt($ch, CURLOPT_POSTFIELDS, "name=$username&password=$password");
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);	
	
	// Execute the cURL session and get the response
	$response = curl_exec($ch);
	
	// Check for cURL errors
	if(curl_errno($ch)){
        	$user = new WP_Error( 'denied', __('Curl error: ' . curl_error($ch)) );
	}
	
	// Close the cURL session
	curl_close($ch);
