Add Stand-Alone Modules

Adding modules is simple. You only need to create a subdirectory under the plugin directory (extension/custom) according to the structure of the zentaoPHP framework, for example, called pay, and then implement the corresponding control, model, view, css, js, lang, and other concepts according to the agreement of the zentaoPHP framework. That's it. It will not be described in detail here. You can refer to the basic manual of our framework.
