Hi everyone, so i have an html and PHP code of a form with following code:

But whenever I submit something, it throws Warning: Undefined array key "hello" in /root/luna/test.php on line 2
I’m clueless and tired. How can I fix that?

Thanks, man. I’m completely drunk.

Why w3schools? Moz is sooo much better, and they don’t have a history of being incorrect.

Guessing you mean MDN? It doesn’t cover PHP.
If not, please send a link to Moz as I can’t find it.

You can get content of forms in any backend language, OP’s backend program is quite irrelevant to the question.
I would 100% recommend MDN when it comes to JavaScript/Web development.

I’m sorry, but you’re wrong here. The title of the post is “Forms in PHP 8.2”, and the post says “i have an html and PHP code”, so the backend language is quite relevant.

I’m on the same boat here, and am only a bit dissatisfied with their search function. W3 uses Google though… so their function was completely broken when I needed it. Don’t question it

Yes you are right that OP has mentioned using PHP which makes it relevant, however the mistake was done in the frontend which means there is no need to use PHP in order to commit such a sin.

That was me in 2019, Idk how you have been to programming and such but you will learn more as you move

Oh yes. There was a website dedicated to pointing that out: https://www.w3fools.com/
You can find their most recent archive here: https://web.archive.org/web/20140531121518/http://www.w3fools.com/, and an archive which documented the errors here: https://web.archive.org/web/20110412103745/http://w3fools.com/.

I concur.

Yeah, my bad

@ChrisPAR

It doesn’t cover PHP.

I think that’s right. But it does not matter, as the part of the code that was incorrect was the HTML, something MDN does cover.

@ChrisPAR

so the backend language is quite relevant.

It is relevant to the question, yes. But it’s not relevant to the anwser.

@Frank419

Oh really?

Oh yeah. There was an entire website dedicated to everything that they had wrong on their site. It was quite the list.
