codegneiter serach filter and resullts

hello coders,  how can i write a filter search box with codegneiter im new .
i would like a complete guide for this. the idea is to use a  html php form  with select options.
once u filter and click search button , u have the results in the same windows.

Hi,

The relevant guide for CI4 is here: http://codeigniter.com/user_guide/librar...ation.html
The same for CI3 is here: http://codeigniter.com/userguide3/librar...ation.html

What you will need is a controller that handles the request and validates your form submission.

And i would use 2 view files:
- for the form
- for the results
