 * Hi to Everyone,
 * A notice appears on the top of my homepage ([http://shanti-music.com/shop/](http://shanti-music.com/shop/)).
   It goes like this: Notice: Undefined index: banner_id in /home/wtjkcewo
 * How do I solve this coding issue? Please note I’m not an IT expert at all… just
   a website owner learning as I go.
 * Thanks in advance.

 * Dear,
    It seems that your site is not powered by WordPress. Are you sure you 
   use WordPress for your site?

 * Hi Daanial,
 * I use a WordPress site ([http://shanti-music.com/](http://shanti-music.com/)).
   The page in question is the shop site for my page and it is powered by OpenCart.
 * However the PHP coding can be accessed at my cPanel pages. I have located the
   exact page where the PHP coding is indicated. I only need to know what I should
   add or subtract in the codes to remove the error notification on my shop homepage.
   Or perhaps could it be more complicated than that?
 * I’d appreciate some assistance.
 * Thanks,
    Helen

 * Hi Helen,
 * Actually I have never worked with OpenCart but if I want to check it I can advice
   you to check shop/catalog/controller/module/slideshow.php on line 17 and probably
   remove the whole banner_id line there, but this can make other problems so always
   make some backups first and be careful with what you do.

 * Daanial,
 * I tried and yes, it caused more problems…
 * This is what’s found on line 17:
    $results = $this->model_design_banner->getBanner(
   $setting[‘banner_id’]);
 * I removed it and got an additional warning on the top of my shop homepage:
    Warning:
   Invalid argument supplied for foreach() in /home/wtjkcewo/public_html/shop/catalog/
   controller/module/slideshow.php on line 19
 * I removed line 19 and saved it. The whole shop page disappeared! LOL. Well I 
   restored everything and we’re back with the original notice on my page.
 * I’ll keep looking into the matter and would certainly appreciate anyone’s input
   for repairing the codes.
 * I’m pasting the whole code found on the slideshow php below in case it makes 
   sense to anyone out there:
 * <?php
    class ControllerModuleSlideshow extends Controller { protected function
   index($setting) { static $module = 0;
 *  $this->load->model(‘design/banner’);
    $this->load->model(‘tool/image’);
 *  $this->document->addScript(‘catalog/view/javascript/jquery/nivo-slider/jquery.
   nivo.slider.pack.js’);
    $this->document->addStyle(‘catalog/view/theme/’ . $this-
   >config->get(‘config_template’) . ‘/stylesheet/slideshow.css’);
 *  $this->data[‘width’] = $setting[‘width’];
    $this->data[‘height’] = $setting[‘
   height’];
 *  $this->data[‘banners’] = array();
 *  $results = $this->model_design_banner->getBanner($setting[‘banner_id’]);
 *  foreach ($results as $result) {
    if (file_exists(DIR_IMAGE . $result[‘image’])){
   $this->data[‘banners’][] = array( ‘title’ => $result[‘title’], ‘link’ => $result[‘
   link’], ‘image’ => $this->model_tool_image->resize($result[‘image’], $setting[‘
   width’], $setting[‘height’]) ); } }
 *  $this->data[‘module’] = $module++;
 *  if (file_exists(DIR_TEMPLATE . $this->config->get(‘config_template’) . ‘/template/
   module/slideshow.tpl’)) {
    $this->template = $this->config->get(‘config_template’).‘/
   template/module/slideshow.tpl’; } else { $this->template = ‘default/template/
   module/slideshow.tpl’; }
 *  $this->render();
    } } ?>
 * Thanks and regards,
    Helen
