Hi CodeIgniter Team,
just started learning Codeigniter and doing step by step your Tutorial.
In:
https://codeigniter.com/user_guide/tutor...how-method
In Controller also in Method you use show instead of view and that doesn't work, it should be named to view
Should be changed in Routing "Routes.php", in Controller "News.php"
it was mixed with view and show

Hello,
I have a question. In CodeIgniter 4, how can I display the path of an uploaded file from the writable/uploads folder?

I upload various file types including images, documents, PDFs, and CSVs using the following code and store the file paths in the database.

everytime i create a new project in CI4 4.6.1 with php 8.2.12 i often get this error, what is wrong?

this error comes out when i first run my application.


trim(): Argument #1 ($string) must be of type string, array given 
error at :  SYSTEMPATH\Filters\Filters.php at line 918

911      * @param array  $paths The except path patterns
912      */
913    private function checkPseudoRegex(string $uri, array $paths): bool
914    {
915        // treat each path as pseudo-regex
916        foreach ($paths as $path) {
917            // need to escape path separators
918            $path = str_replace('/', '\/', trim($path, '/ '));
919            // need to make pseudo wildcard real
920            $path = strtolower(str_replace('*', '.*', $path));
921
922            // Does this rule apply here?
923            if (preg_match('#\A' . $path . '\z#u', $uri, $match) === 1) {
924                return true;
925            }

log :

Hi
What am I doing wrong?

Hi,
I make an AJAX request in POST to CI, sending some data, including some data in the format:

Good afternoon. We have a website running on Codeigniter 4. The website has been working stably for more than three years, but yesterday something happened and the main page of the website stopped working, the server issues a 500 error. However, all other pages of the site are working correctly. Part of the server log is attached.
How can I fix this error?

I have a codeigniter 4 app that has to live in a shared hosting enviroment and has to be in a subdirectory.
The app has been developed with legacy autorouting enabled.
The app has indexPage as index.php

All the autorouting routes end up throwing a 404 with the "index.php is not a valid controller name" statement.

1. Steps to Reproduce
2. get an apache webserver
3. set indexPage  as index.php in your app/Config/App.php
4. install codeigniter in a subdirectory:
/var/www/html/code-igniger-app
/var/www/html/other-apps-here
this way you'll access the app from http://localhost:8080/code-igniger-app/index.php
5. enable legacy autorouting and create a controller

The problem seems to be that having codeigniter 4 in a subdirectory results in the $_SERVER["SCRIPT_NAME"] variable to become: "/code-igniger-app/public/index.php".
If the SCRIPT_NAME has "/public" the parseRequestURI method from the CodeIgniter\HTTP\SiteURIFactory class on line 137 does not remove "/code-igniger-app/index.php" from the uri and it tries to use index.php as the controller name.

I have opened this issue on github: https://github.com/codeigniter4/CodeIgni...ssues/9602 but I've been told this is a misconfiguration, I tried to follow the official guide but I could not get it to work, can someone help me figure out where I've gone wrong?
Thanks
