Can helpers be nested too?

It's important to note that while nesting helpers in subfolders can help organize your code, it's not always necessary. If you have a small number of helpers, it may be simpler to keep them all in the main "helpers" folder.

However, if you have a large number of helpers or if you want to group related helpers together, nesting helpers in subfolders can make your code more organized and easier to maintain.

In addition, it's worth mentioning that you can also autoload helpers in CodeIgniter by adding them to the "autoload.php" file in the "config" folder. This can be useful if you have a helper that is used frequently throughout your application.

To autoload a helper, simply add its name (including the subfolder name, if applicable) to the "autoload['helper']" array in the "autoload.php" file. For example, if you want to autoload the "myhelper" helper from the "subhelpers" folder, you would add the following line to the "autoload.php" file:


$autoload['helper'] = array('subhelpers/myhelper');
This will automatically load the "myhelper" helper whenever your application runs, without the need to manually load it in each controller.

In summary, nesting helpers in subfolders in CodeIgniter is possible and can be useful for organizing your code. To load a nested helper, use the "helper" function in your controller, and to autoload a helper, add its name to the "autoload['helper']" array in the "autoload.php" file.
