how to get limited number of records and order by rand ?

1)you might be able to do something like lever use of

Code:

rand($min,$max)

and use codeigniter built in models utility :

Code:

public function getOne($id)
       {
      
      return $this->find($id);
          
       }

you would have to do count but id might not start with min nor end with max.

2)this is how i set out my assetts:

Code:

public
├── blogImages //dir
├── captcha   //dir
├── css       //dir
├── errors
├── favicon.ico
├── fonts  //dir
├── images   //dir
├── index.php
├── js    //dir
├── minCss   //dir
├── portfolio //dir
├── robots.txt
└── sounds    //dir

Code:

js

│   ├── jquery-3.5.1.min.js
│   ├── jquery-migrate-3.3.0.js
