Create the Basic Plugin Structure

The most simple plugin has only one folder and one file. Both must have the same name. So the basic file structure for our plugin looks like this:

/cookieconsent // plugin folder
- cookieconsent.php // plugin file

cookieconsent.php contains the main logic and central entry point of our plugin, Bbt we need some more files. Let us describe again, what our plugin should do:

• The plugin should add a CSS file to all templates, so we have to add this file.
• The plugin should add a JavaScript file to all templates, so we have to add this file.
• The plugin should add the initial script with the values for the colors and the content. We will do this with a separate Twig template.
• The content and color values should be editable in the setup of TYPEMILL. We will do this with a plugin configuration file.

If we simply follow this description, then the file structure of our cookie consent plugin looks like this:

/cookieconsent
  - cookieconsent.php
  - cookieconsent.yaml
  /templates
     - cookieconsent.twig
  /public
     - cookieconsent.min.js
     - cookieconsent.min.css

As you can see, a clear description of the plugin's functionality is the key. Coding is so much easier if everything is described in clear words.

Let's go over the naming conventions again:

• The name of the folder is the name of your plugin.
• The initial PHP file must have the same name as the folder, and must be located in the root of your plugin folder.
• The YAML configuration file must have the same name as the folder, and must be located in the root of your plugin folder.

The names and the structure of all other files and folders are a matter of taste, and are completely up to you.

Next Step: The Configuration File

We have a structure now, so let's start with a basic configuration file before we write our first PHP code for the plugin.
