Salmon Library

Salmon Library

Developed By Grizzlyware Ltd

Compatible with WHMCS v8.1

Salmon WHMCS PHP Library

Salmon for WHMCS extends (and creates in some cases, where defaults do not exist) the default WHMCS classes to allow for richer IDE integrations and a community driven array of helper functions.

It also contains a Data Store helper, which allows you to store data in a WHMCS installation without running a single database migration or SQL query manually. That means you can persist data without writing your own schema and complex module activate or delete methods. Use it to store remote IDs for services or to keep track of the internal state of a service where the service status isn't enough.

As Salmon is available via GitHub and open source, you can suggest and add new features and benefit from a rapid release cycle in your own apps:

WHMCS Module

You can download the WHMCS module, which will install Salmon as a hook and make it globally available, great for simple tweaks.

Via Composer

If you're comfortable using Composer, you can install Salmon by running the following command:

composer require grizzlyware/salmon-whmcs

New features

Get in touch with us or create an issue on the GitHub repository, we're actively developing Salmon to save ourselves time when working on customer projects and rapidly releasing new features.
