I really appreciate that you leave in the "mistakes" and then go and correct them. Not only is it a useful tool for teaching, it's also encouraging that even seasoned programmers make mistakes, and it's no big deal, you just go track it down, fix it, and move on.

Great video! Great channel! please don't stop uploading, these tutorials are a godsend for anyone looking to build anything in Codeigniter 4. I do have a question, how can you get the "getRandomName()" parameter and file path to insert into your database after file upload?

Hi Alex. I previously asked for a video on creating modules but, having done a little more research, perhaps an in-depth explanation of namespaces would be better. That seems to be at the core of creating modules.

Hi sir! I was following all your tutorials and it's really helpful! But at this moment I have encountered an error when using the uploaded rule. It states: TypeError: date() expects parameter 2 to be int, bool given when using single upload file.

[MirkoRuggirello]

Congratulations on all your videos, you are helping me a lot! I don't understand why when I submit the form it also inserts an empty index.html in the new folder! What could I have done wrong? Thanks
