After doing more research, I finally get it to work the way I wanted. I would give a full credit to Catch Box WordPress theme because I studied and used their codes.
Quick Note:
- There are only two files you need to touch.
function.php
andinc/widgets.php
from Catch Box theme.
Solution:
- Step One:
- In your theme’s root directory, go to function.php.
- Open it. At the end of the file, add this following line of code:
require trailingslashit( get_template_directory() ) . 'include/widgets.php';
-
Step Two:
- Assuming your theme has a folder called include just like mine. Feel free to have any name you want. Go to that include folder and create a empty file called
widgets.php
- Now open that empty file and paste the following code and save it. Make sure to replace the catchbox_adwidget with your own widget class. These code are from Catch Box theme,
inc/widgets.php
- Assuming your theme has a folder called include just like mine. Feel free to have any name you want. Go to that include folder and create a empty file called
widgets.php:
