Opencart Architecture

early notes on OpenCart architecture, mostly how language files are defined, loaded and read in controllers

Libraries

Languages are stored in catalog/language/ and loaded in Controllers

The Values that are used across many pages are stored is english.php. If you want to add a new value just follow the syntax below:

1$_['language_key']='This is test';

The languages based on special pages are located inside the folders. For example, for error page the language file can be found at:

catalog/language/english/error/not_found.php

Language file can be loaded into controller by using the syntax as below:

1$this->language->load('error/not_found');

1$this->language->get('language_key');

1$this->language->load('route path of the language');

to get the specific language data use this syntax

1$this->language->get('language file data keyword');
