vqmod background image change throws php notice in opencart - php

Question

I have installed background_image.xml inside vqmod xml folder to change background image in opencart. This plugins works perfectly but throwing a notice at the header.
Notice: Undefined variable: server in C:\wamp\www\opencart\vqmod\vqcache\vq2-catalog_controller_common_header.php on line 54
this is the plugin link:
http://www.opencart.com/index.php?route=extension/extension/info&extension_id=16044&filter_search=background&filter_license=0
I also tried error_reporting(0) but no result. Here is the code of vqmod\vqcache\vq2-catalog_controller_common_header.php

Can anyone help me to solve this problem?

Answer 1

The problem is that - in default opencart, the below lines of code exists at the begginning of catalog/controller/common/header.php (line 6):
if (isset($this->request->server['HTTPS']) && (($this->request->server['HTTPS'] == 'on') || ($this->request->server['HTTPS'] == '1'))) {
$server = $this->config->get('config_ssl');
} else {
$server = $this->config->get('config_url');
}
In your case the above lines code got removed. Please check the file vqmod\vqcache\vq2-catalog_controller_common_header.php and make necessary changes to bring back the above lines of code. If you're using more vqmod files, check them also.
An easy fix is to change (probably in your xml file):
$this->data['backgroundimage'] = $server . 'image/' . $this->config->get('config_backgroundimage');
to
$this->data['backgroundimage'] = $this->data['base'] . 'image/' . $this->config->get('config_backgroundimage');
Have a nice day !
