What happened?

When CSRF Filter is On.
I encountered a TypeError when using the form_open('').
The error message is as follows:

TypeError
str_contains(): Argument #1 ($haystack) must be of type string, CodeIgniter\HTTP\SiteURI given
SYSTEMPATH\Helpers\form_helper.php at line 65

58 }
59 
60 $form = '<form action="' . $action . '"' . $attributes . ">\n";
61 
62 // Add CSRF field if enabled, but leave it out for GET requests and requests to external websites
63 $before = service('filters')->getFilters()['before'];
64 
65 if ((in_array('csrf', $before, true) || array_key_exists('csrf', $before)) && str_contains($action, base_url()) && ! stripos($form, 'method="get"')) {
66 $form .= csrf_field($csrfId ?? null);
67 }
68 
69 foreach ($hidden as $name => $value) {
70 $form .= form_hidden($name, $value);
71 }
72 

Debug

// vendor\codeigniter4\framework\system\Helpers\form_helper.php line 65

var_dump(in_array('csrf', $before, true)); // true
var_dump(array_key_exists('csrf', $before)); // false
var_dump(str_contains($action, base_url())); // error

if ((in_array('csrf', $before, true) || array_key_exists('csrf', $before)) && str_contains($action, base_url()) && !stripos($form, 'method="get"')) {
 $form .= csrf_field($csrfId ?? null);
}

Steps to Reproduce

1. Upgrade CodeIgniter to 4.5.0 from 4.4.7.
2. Use the form_open('') function in View.

Expected Output

<form action="current_url" method="post">

Anything else?

This issue did not occur when using CodeIgniter version 4.4.7.
Any help on this issue would be greatly appreciated.

I was able to confirm the reproducibility.
An error occurs when using CSRF filter.

// app\Config\Filters.php line 70
 public array $globals = [
 'before' => [
 // 'honeypot',
 'csrf',
 // 'invalidchars',
 ],
 'after' => [
 'toolbar',
 // 'honeypot',
 // 'secureheaders',
 ],
 ];

Debug

// vendor\codeigniter4\framework\system\Helpers\form_helper.php line 65

var_dump(in_array('csrf', $before, true)); // true
var_dump(array_key_exists('csrf', $before)); // false
var_dump(str_contains($action, base_url())); // error

if ((in_array('csrf', $before, true) || array_key_exists('csrf', $before)) && str_contains($action, base_url()) && !stripos($form, 'method="get"')) {
 $form .= csrf_field($csrfId ?? null);
}

It works when change it to

str_contains((string)$action, base_url())

[kenjis]

Check #8736
