The Hello World! Example as a CoolBrew Tag
Let's rework the Hello World! example from the CodeIgniter User Guide to create a simple CoolBrew module and controller. Start by creating a new module folder by duplicating the _default folder inside the system/modules/ folder and renaming it hello.
Now, using your text editor, create a file called hello.php, and put the following code in it:
Then save the file to your system/modules/hello/controllers/ folder.
Now, using your text editor, create another file called hello-test.php, and put the following code in it:
Now save that file to your website's document root folder and visit your site using a URL similar to this:
http://www.your-site.com/hello-test.php
If you did it right, you should see Hello World!.
More Tags
In the above example the function name is world(). You can add more tags to your controller by creating more functions. Add a new function to your controller:
Now, add a second tag to your hello-test.php file, save it and upload it to your website's document root folder.
Load the same URL as before to see the additional letterman tag display:
http://www.your-site.com/hello-test.php
