How to use post in php? [SOLVED]

Question

I have virtual web (centos 6.10, php version 5+) and I'm trying to make request with post, however array $_POST is empty, Somebody know what could solve this?

Answer 1

With forms(application/x-www-form-urlencoded), it should work if method="post".

However $_POST does not work for other Content-Type. You have to manually read 'php://input' stream.

Can you share the php code? Also verify that your form's method is POST.

Answer 2

Are you sure there is an input field with name="user" in the submitted form?

Answer 4

Try to manually read php://input stream. It should contain the said data.

Answer 5

Hmm 🤔

Answer 6

nicolas turek I know it is JS. I was talking about your PHP. According to you, 'files' and 'files/' both point to the same route but 'files' (without slash) does not send the posted data. To me, that is a flaw in the routing system of your website. You should either return a 404 response or trim the extra slash.

Answer 7

How are you making the request?

Answer 8

I tried form and xmlhttprequest (with get it works)

Answer 9

Versions:
Php 5.3.3, Apache 2.2.15

Php:
<?php
if(isset($_POST["user"]))echo "ok";
else echo "ko";
?>

Answer 11

Answer 12

Problem is in post, not way I get things to there, I think it could be something with server

Answer 13

Thanks for this, no solution worked sadenly

Answer 14

Ok, I find solution by myself - it's really stupid: there has to be / at the end of url :D

Answer 15

My first request open part was (not working):
req.open("POST", "files", true);
Working:
req.open("POST", "files/", true);

Answer 16

nicolas turek Are you using a router script or relying on file system based routing?

Answer 17

No, that's js, just I'm lazy writing whole script, only thing you need to know, that req is instance object of xmlhttprequest

Answer 18

The thing I'm doing include json files, so I don't think it's possible to do it with sololearn
