     // CIFX.php FX wrapper file at

     // CI path: application/libraries/CIFX.php

     // FMP WPE data (IP, port, server version,

     // and url scheme) is in custom config file at

     // CI path: application/config/CIFX.php

     $this->load->library('CIFX');

     // tell FX which DB, layout to use and

     // how many records to return

     $this->cifx->SetDBData('buzzerbeater.fp7', 'Users', 1);

     // build a find request, field name, data, comparison

     $this->cifx->AddDBParam ('id', $id, 'eq');

     

     // do find, return dataset, no flattening, meta object

     $res = $this->cifx->DoFXAction(FX_ACTION_FIND, TRUE, TRUE);
