How to use view to load a CSS file

Your error states Argument 3 passed to view() must be of the type array, boolean given. A look at the code for the view() function shows it's looking for an $options array, which really only has one valid value at the moment: 'saveData'. Where in the manual is it stating to pass a true/false as the third parameter? We need to update that if you can show us where.

From the Online Manual:

/*
Maybe incorrect Boolean $saveData - should be array['save'=true]; ?
*/
https://bcit-ci.github.io/CodeIgniter4/g...t=savedata
$data = [
        'title'   => 'My title',
        'heading' => 'My Heading',
        'message' => 'My Message'
];
echo view('blogview', $data, ['saveData' => true]);
Additionally, if you would like the default functionality of the view method to be that it does save the data between calls, you can set $saveData to true in application/Config/Views.php.

//================================================
I managed to solve the problem of using View to load a CSS file:

CodeIgniter\View\View::render ==> Line: 170

PHP Code:

# echo  __method__ .' ==> Line: ' .__line__ ;die;

# IF AND ONLY IF APPEND .php WHEN NO FILE EXTENSION EXISTS
  if( strpos( $view, '.' ) ):
    # ASSUME FILE OK AND DO NOT APPEND .php
      $this->renderVars['view'] = $view;
  else:    
   # ORIGINAL SCRIPT 
     $this->renderVars['view'] = str_replace('.php', '', $view) . '.php';
  endif;
