CodeIgniter 4 Access denied message and a 403 response code in browser when hosting with Apache in Laravel Homestead.

It works fine with php spark server but when hosting with Apache the problem happens.

It can be useful to use the request object in a view to retrieve input, this was easy with CodeIgniter 3 but with CodeIgniter 4 the documentation doesn’t cover this.

Add this to the top of your view

<?php
$request = \Config\Services::request();
?>

Then you can use the request methods like this

<input type="hidden" id="score" name="score" value="<?=$request->getVar('score')?>">

To prevent the debug toolbar from appearing for a certain controller method when in development mode, for example if you are generating a CSV file with code, edit app/Config/Filters.php and add the following

    
public function __construct()
{
  // hide debug toolbar when generating a CSV file
  if (strpos($_SERVER['REQUEST_URI'], 'export_csv')) unset($this->globals['after'][0]);
}

It isn’t obvious from the CodeIgniter 4 documentation how to prevent the debug toolbar from being added to the bottom of text output with a ResourceController.

Either output an array which changes the content type to application/json,

edit app/Config/Filters.php

public $globals = [
        'before' => [
            // 'honeypot',
            // 'csrf',
        ],
        'after' => [
            // 'toolbar',
            'toolbar' => ['except' => 'feedback/*'],
            // 'honeypot',
        ],
    ];

Or use header X-Requested-With set to XMLHttpRequest in a REST client like Postman.

This is the WordPress way to add inline JavaScript if you have no script dependencies:

wp_register_script( 'dummy-handle', '' );
wp_enqueue_script( 'dummy-handle' );
wp_add_inline_script( 'dummy-handle', 'var my_variable = true;', 'before' );
