Upgrade Views #############

Documentations

• View Documentation CodeIgniter 3.x <http://codeigniter.com/userguide3/general/views.html>_
• :doc:View Documentation CodeIgniter 4.x </outgoing/views>

What has been changed

• Your views look much like before, but they are invoked differently ... instead of CI3's $this->load->view('x');, you can use return view('x');.
• CI4 supports :doc:../outgoing/view_cells to build your response in pieces, and :doc:../outgoing/view_layouts for page layout.
• The :doc:Template Parser <../outgoing/view_parser> is still there, and substantially enhanced.

Upgrade Guide

1. First, move all views to the folder app/Views
2. Change the loading syntax of views in every script where you load views:
   • from $this->load->view('directory_name/file_name') to return view('directory_name/file_name');
   • from $content = $this->load->view('file', $data, TRUE); to $content = view('file', $data);
3. (optional) You can change the echo syntax in views from <?php echo $title; ?> to <?= $title ?>
4. Remove the line defined('BASEPATH') OR exit('No direct script access allowed'); if it exists.
