I get the following error

You must set the database table to be used with your query
Using the code below ( it seems to me that tables name are set )

Any hint to fix the issue? Thanks a lot

Code:
public function index(): string

   $this->viewData['total'] = $total; 

   return view('pages/public/registers/civil/main', $this->viewData);

Code:

≪ Previous: Codeigniter 4 and DB hosted in Kubernetes

Hi Everyone,
I'm working on a web application using CodeIgniter 4 and need some advice on implementing a secure and scalable Role-Based Access Control (RBAC) system. I’ve come across different approaches, but I’m looking for guidance on the most efficient and maintainable way to handle user roles and permissions.
Here’s a bit of context:

My application requires user roles like Admin, Manager, and User, each with different access levels.
Users need varying permissions to access controllers, methods, and specific resources.
I want a solution that’s easy to manage, scalable for future roles, and minimizes database queries.

I’ve seen solutions that involve:

Storing roles and permissions in the database and checking access in controllers using middleware.
Using filters to handle permissions, but I’m unsure how to best configure them for dynamic role checks.
Extending BaseController to handle access control.

Questions I have:

What’s the best approach for integrating RBAC in CodeIgniter 4 while maintaining performance?
Is it better to handle role checks in controllers, middleware, or elsewhere?
Should I use a third-party library, or is it better to create a custom solution?
Are there any pitfalls I should be aware of when implementing RBAC in CI4?

If anyone has a sample implementation or can point me to a detailed guide, it would be greatly appreciated! Any best practices for azure interview questions or personal experiences would also be helpful.
Thanks in advance for your help!

I'm using multiple subdomains and hostnames within an application. It looks like the anchor function uses the current URL to build the link element, however, it doesn't respect the current subdomain. So, while using a.example.com, the link will point to example.com domain.

The current URL's host is the "example.com" domain, so from the anchor output, that's not unexpected, I suppose, but incorrect...

Hey everyone! ?
I’d like to showcase my travel-related blog/website, TravelStyleMate, which I built entirely from scratch using the CodeIgniter 4 framework and the Auth System From Shield. My goal was to create a fast, optimized, and feature-rich travel platform while maintaining full control over performance and design.

? Features & Highlights:
✅ Custom-Built Travel Blog – Not based on WordPress, but designed to function like a modern blog with full flexibility.
✅ Sections for Blog Posts, Captions & Destinations – Structured content to make navigation easy and engaging.
✅ Optimized for Speed & Performance – Implemented every possible speed optimization, ensuring fast load times. (It shows 80+ in Google Page Speed Now)
✅ Unused CSS Removal System – Automatically scans views and removes unused CSS using

Code:
sabberworm/php-css-parser

.
✅ Bootstrap-Based with Customizations – Built on Bootstrap but customized to match my requirements.
✅ Table of Contents System – Similar to Rank Math’s TOC, integrated into the content dynamically.
✅ SEO-Friendly & Scalable – Focused on growth with SEO-friendly structures.

Future Plans:
I’m continuously improving the site, adding more features, and fine-tuning the user experience. Would love to hear feedback from the community!

I know this is an off subject for many but thought I'd ask anyway.... I have a Scaffold/CRUD Gen that I have been working on specifically for myself. I started it a while back, found some that were cool and modeled after them a bit but it wasn't very modular and code updates kept breaking everything. The last one I found back in 2020 was good from Adel (https://github.com/Adel-Qusay/Codeignite...-generator) so I modeled mine over the years like this one. I just refreshed the code so it works great with PHP 8.2 and CI4 4.6. And, NO it is not a copy of Adels code aside from a few Token names Smile

(to be honest DeepSeek did it all in one pass)
I have tested it -in codeigniter 4.6, and it works as the original did.

If somebody has the time to review, test, document, so it could be included in the framework, or set out as a module, it would be awesome.

how to manage DB connections

≫ Next: Set session expiration time based on user role in CodeIgniter 4

≪ Previous: Debugbar not showing up

Hi If so how do Team,
In my CI3 app I never worried about this because we autoloaded 'database' lib.
In CI4 it seems I now have to connect in my code - I have chosen the constructor of any Controller or Model where ever I need to access the database.
I am now aware that I could hit connection limits (currently 151 by default for mysql db)
A few (perhaps) obvious questions:
1) If I make a connection in a controller and the user session redirects to another controller will the $db persist for the session or do I open a second etc connection?
2) Should I check for an existing connection in each constructor and either proceed or open a new connection as appropriate? If so how please?
3) Another potential strategy would be to force a disconnect on completion of my db interation. If so how please?
4) I quite like the freeQuery() call. Is this recommended to optimise memory as lng as you don't need the cached result?
I have read the upgrade notes carefully but haven't found those nuggets yet.
Appreciate any thoughts and guidance.
TIA, Paul

Set session expiration time based on user role in CodeIgniter 4

≫ Next: CodeIgniter Sandbox

≪ Previous: how to manage DB connections

Hi everyone,

I'm working with CodeIgniter 4 and I need to configure the session expiration time dynamically based on the user role at login.

I understand that, by default, CodeIgniter loads session settings from app/Config/Session.php, where the 'expiration' value is defined. However, this configuration is static and applied globally.

What I want to achieve is something like this:

If the user has the admin role, their session should last longer.
If the user has a standard role, the session should expire sooner.

I’m wondering if there’s a recommended way to override the session expiration time at runtime based on the user role. Is it possible to change the expiration after login, or would I need to implement a custom logic to handle expiration manually?

Any advice or example would be greatly appreciated.
Thanks in advance!

Hello!

I've started working on a CI4 project that is already running for a while now and has a bunch of complex data and db structure but does not uses migrations.

As the documentation itself states:

Quote:You could edit fragments of SQL by hand but you would then be responsible for telling other developers that they need to go and run them. You would also have to keep track of which changes need to be run against the production machines next time you deploy.

And those are exactly the problems we are having!

That being said, I wanted to know how exactly are you supposed to use migrations in production. Should I configure my deploys to run the command "php spark migrate" automatically? Is it safe? What do you recommend as the correct approach and steps to do it correctly and safely?
