Understanding Kotchasan Structure: How to Modify Pages and Related Code

Many developers often ask where to modify a specific page in a program built with Kotchasan. Although I have already explained this in the Router The Heart of the Framework documentation, many developers may not have read it. So, I will summarize it again here.

URL Structure and Related Files

Kotchasan uses a single URL structure to access different pages. The most common URL format is

When this URL is accessed, the framework will load the file

The render method or the class \Directory\Page\Controller::render is executed first. Then, it will call other related classes

1. View (Displays the page content)

   • File: modules/<directory>/views/<page>.php
   • Class: \Directory\Page\View

2. Model (Handles database and data management for the page)

   • File: modules/<directory>/models/<page>.php
   • Class: \Directory\Page\Model

When No directory is Specified

If the URL does not include a directory, such as

Kotchasan will automatically use the index directory, meaning the system will call

Role of Each Component in MVC

• Controller (\Directory\Page\Controller)

  • Checks user access permissions
  • Prepares page headers such as Title, Breadcrumbs, and Menus
  • Passes data to the View

• View (\Directory\Page\View)

  • Manages the page display, including tables and forms

• Model (\Directory\Page\Model)

  • Fetches data from the database for the View
  • Handles form submissions and table actions

URL Structure for Model Actions

In addition to the standard URL format, another format you might encounter is

This calls the action method in the Model file

Typically, this type of URL is used for table actions, such as saving, deleting, or updating data.

Conclusion

If you need to modify a page in Kotchasan, analyze the URL structure and edit the relevant Controller, View, or Model according to the MVC pattern.
