php - OpenCart: Create custom controller class -


i have custom script meant generate images customer.

i need script part of controller, because need script able use:

if (!$this->customer->islogged()) {         $this->session->data['redirect'] = $this->url->link('account/download', '', true);          $this->response->redirect($this->url->link('account/login', '', true));     }

in order check if customer logged in. otherwise, can access link when logged out, dangerous shop.

in custom script, have included:

<?php require_once('system/engine/controller.php'); class controllertestabc extends controller{      public function index()      {           echo 'hello world';           exit;      } } ?>

i'm echoing hello world see if page run. however, page blank.

note: attempting access script using href like:

$viewimg ="<a target='_blank' href='view_code.php?id=".$id."&showdate=".$showdate." 'class='cat_links'>".$showname."<font size='-1'></a>";

why page blank? i've included path controller engine, function index() doesn't run.

why page blank?

you're getting 500 error. check log file.

if don't know php logging add: phpinfo();exit; @ top of script temporarily , show error log in use.

alternatively, try temporarily turning on logging screen with: ini_set('display_errors',1);error_reporting e_all;
