class Mylibrary{
    private $CI;
    public function __construct()
    {
        $this->CI =& get_instance();
        $this->CI->load->helper('url');      
        $this->CI->load->database();
        
    }
 
   function show()
    {
        // Your logic
    }
}
 

If you want your libraries to be auto load always, the you can add your custom library in $autoload[‘libraries’]  option array in config.php file. Step 2:- If you want to load library in your controller then you can load library in controller file like

1

//  load the library
    $this->load->library('mylibrary');
 

Step 3:- Now your library created and you can use your library method in controller like

// In any controller
$this->mylibrary->show();
 

  I hope you might have understood it

In this article, I am going to explain “How to Add dropbox file picker/chooser on the website”.  The Chooser is the fastest way to get files from Dropbox into your web app. It’s a small JavaScript component that enables your app to get files from Dropbox without having to worry about the complexities of implementing a file browser, authentication, or managing uploads and storage. However, most users now store their files in the cloud (Microsoft OneDrive, Google Drive, Dropbox, etc.). So, it can be a great idea to allow users to select files directly from their cloud provider. Let’s see how to add the Dropbox File Picker to a website! Step 1:- The first step in adding the Chooser to your app is to create an app. Using the Chooser doesn’t require production approval, so you can publish your integration to your users as soon as you’re ready. When you

In this article, I am going to explain “What is helper and How to create own helper” in CodeIgnotor What is Helper In CodeIgniter there are helpers which are there to help you with different tasks. Every helper file is a collection of functions aiming towards a particular role. Some of the helpers are ‘file helpers’ which help you to deal with the file, ‘text helpers’ to perform various text formatting routines, ‘form helpers’ to create form element, ‘cookie helpers’ set and read cookies, ‘URL helpers’ which assist in creating links, etc. Loading a Helper A helper can be loaded in controller constructor which makes them globally available, or they can also be loaded in specific functions which need them.
