PHP Settings? PHP not receiving POST data

Question

I’m sending a .php file POST data from a java application. The .php file is not accepting the POST data. file_get_contents(‘php://input’) is empty and $_POST is empty. I know the problem isn’t with the .php file or java application because I tested it using a different host and it worked. Is there a setting in php.ini I’m missing or a setting I need to change?

Can you describe your server environment. – Hekking

maybe you have this problem #5541862 – Premonitory

Check for max post size, and uploaded files in PHP appears in $_FILES not $_POST – Briant

Answer 1

I had this problem too. For future visitors, my issue was missing the trailing slash in the url. Eg..

http://someplace.com/cheeseburger

should have been...

http://someplace.com/cheeseburger/

This was causing the post to fail, in my case.

Thanks! This saved me from a headache! I didn't know there was such a difference between these, maybe at least on Apache. – Grazynagreabe

If the Content-Type is empty or not recognized in the HTTP message then the PHP $_POST array is empty. If you cannot send the Content-Type you can add this to your PHP:

if(empty($_SERVER['CONTENT_TYPE']))
{ 
 $_SERVER['CONTENT_TYPE'] = "application/x-www-form-urlencoded"; 
}

You can also check if you have the correct settings in your php.ini

; Maximum size of POST data that PHP will accept.
post_max_size = 8M

If post_max_size is 0, PHP will not populate $_POST.

variables_order = "EGPCS"

If you do not have P in there, $_POST will not be set either.

I tried that, but it didn't work. I don't see how it could work on one host but not work on another. Godaddy is my host. It doesn't work on Godaddy, but it works perfectly fine on hosting24.com – Honeyhoneybee

The max size is 128M. P is in there. – Honeyhoneybee

Another idea would be doing a diff between the php.ini files of the two servers. – Hafler

Answer 3

I had the same issue. The problem was http:// and https://

Answer 4

I was having the same problem. It turned out to be because I was prefixing my target with http . I changed it to https and it worked.

Answer 5

My problem was duplicate names for an input.

ex: /input name="test" type="text" / /input name="test" type="text" /

each must have a different name ex: /input name="testA" type="text" / /input name="testB" type="text" /

Answer 6

My problem appeared out of nowhere. I'm using an apache hack to hide the extension, so all I had to do is to remove .php from the file name and it worked.

/* from: */ action = "folder/filename.php"
/* to: */   action = "folder/filename"

I hope this answer helps someone else in the same situation 😎

Answer 7

My problem was that I was requesting to http instead of https
Due to using Cloudflare proxy and I was not forced to switch from http to https
So it still returns the result but the POST is not received.
