I’m building a lightweight affiliate system using CodeIgniter 4, where users can generate and share unique referral links—similar to how GrabCash manages its Profit Links system.
I want to track the following data:

• Clicks on each referral link
  
• Source of traffic (e.g., WhatsApp, Instagram, etc.)
  
• Basic analytics like IP address, timestamp, and referral ID
  

Good morning,

I have a problem that I can neither solve nor understand:
Let me explain better:

I develop locally, I see the site with php spark serve. everything is perfect.
I do git clone on a remote machine.
I then run composer install and then composer update to install and update all the dependencies.

Of course I go to update app.baseURL with the address of the remote machine, but I get the error:

Call to a member function routes() on null

The first thing that comes to mind is the shield. So I go to check if the shield is installed correctly.

After doing this, I am completely blocked and I don't know what else to check.

Hi peeps, just wanted to say hi, because I'm so happy to rediscover CodeIgniter.

Loved CodeIgniter back in the day, although I did not do anything big or advanced with it.

CodeIgniter 4 is looking great and it's still so fast and straightforward.

Professionally (and personally) I've mostly used Joomla! and WordPress for years and years. Magento as well (up to version 2).

Other than development, I've been a ecommerce-/marketing manager for years as well.

As an old school dev, I really don't want to learn how to create Gutenberg blocks etc. I never had the time or a reason to become a javascript wiz or learn React.

Although I will probably try Vue.js with CodeIgniter for fun.

I was a big CMS and framework nerd back in the day. Had to try almost everything

CMS's are great, especially for when multiple people are working on content. But for personal projects their structure can be a pain. I'm so used to fight WordPress that when using CodeIgniter I have to remind myself that it's OK to do things like I want.

Although both WordPress and Joomla! have CLI, task managers etc. Joomla! is probably my #1 (version 5 is really good and the code is modern), but the implicit demand and awareness from clients is WordPress.

As for the short term with CodeIgniter:

• Go through a bunch of tutorials / buy books or courses (if any)
  
• Create a few personal projects:
  
• As mentioned above, something that uses vue.js (admin of some sort/web app)
  
• API integrations
  
• Probably a Programmatic SEO project of some sort (probably data presentation from some dataset / AI generation or a combination of both)
  
• Simple CMS (essentially just admin for the projects, I'm not going to create a generic CMS)
  
• Something else?
  

Hai, i got a case, the issue is im just try to build pagination using paginate and pager in model. So i create manualy using service('pager') like the user guide, and i check this pager like $detail = $pager->getDetails(). but there is a bug in  $detail['uri']->getQuery().

My query string in browser 'limit=10&page=3&search=bar'
The pager getQuery didnt work well, the number page is not correct and sometimes the page is gone leaving the limit and search, every i reload the browser its a random.

Okay before that sorry for my bad english, and im newbie

Anybody know about website Rendering issues? I have website showing good live but when i check my website Live Test HTML code from GSC it show many section up and down, nothing align, why this happening, any developer know why?

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
