The whole codebase consists of several applications primarily written using PHP and .Net. All the applications are centralized around CRM, a customer relationship management system written in PHP.
CRM
CRM is a web application consisting of several modules. It mainly uses the following techstack.
- PHP
- Yii 1.1
- MVC architecture
- SQL Server
Where to find the code for a URL?
Let’s say you are asked to perform a task on the following URL:
mt2.itserver.biz/admin/indexyii.php?r=orders/placeOrder
While coding and testing, we shall use the local URLs, so our URL will change to
mt2.itserver.biz.local/admin/indexyii.php?r=orders/placeOrder (notice .local at the end of domain name)
Now, to find the code, you will take the r query parameter. It currently has a value of “orders/placeOrder“. The part before the “/” (orders) indicates controller and the other one suggests action.
The controllers are located at: httpdocs/admin/protected/controllers, you will go to the OrdersController.php and search for action<ActionName> or actionPlaceOrder.
The action will likely be returning a view like this
$this->render('view_name', ...)You can find the view in httpdocs/admin/protected/views/<controller>/<view>.php.
Reporting
CRM uses crystal reports and SQL server to create detailed reports for users. Here is an example of a report:
Code and actual Crystal Reports files can be found in httpdocs/report directory.
More details can be found here: (TODO)
Custom
BEFORE PLACING ANYTHING IN CUSTOM – YOU MUST ASK PERMISSION FROM YOUR TEAM LEADS
CRM runs on several domains, therefore, a new module is introduced to help you write and deploy code without affecting other domains. Custom allows you to write code for a specific code only.
The custom folder is located at httpdocs/custom. The code for a specific domain can be placed in httpdocs/custom/<domain.local> folder.
Let’s say you are creating something for mt2.itserver.biz, we can place our code like this (notice the .local suffix):
| Original Directory | Custom Directory | Description |
| httpdocs/admin/protected/views | httpdocs/custom/mt2.itserver.biz.local/views | |
| httpdocs/admin/protected/report | httpdocs/report/report |
ITLCommon
ITLCommon contains a lot of reusable code for global application, this is a helper and can be found at httpdocs/admin/protected/helpers/ITLCommon.php.
