PHP Post Not Working

PHP POST not working but GET works

Please make sure the "enable_post_data_reading" variable is set to "on" in php.ini. I have tried the same script on MAMP and it's working fine. So, It's your server settings issue.

PHP POST not working

If you're just refreshing the page, do:

action=''

instead of:

action="<?php echo $_SERVER['PHP_SELF'];?>"

Also, add this to line 2 to see what's being stored (if anything) in the $_POST array:

var_dump( $_POST );

Hmm... so it's empty on submit? Try adding this to the top of your php file:

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

Okay, now check your php.ini (normally requires sudo or root in /etc):

post_max_size = 8M
variables_order = "EGPCS"

Do you have those two rules set? If so, be careful of how much memory you're allocating. Anything over 2048MB could start to give you trouble, depending on your system specs.

NOTE: If you make changes to your php.ini file and PHP is running as an apache module, you'll need to restart apache. Something along the lines of:

sudo /etc/init.d/httpd restart

Post method not working in PHP

Updated to PHP 7.0 and it's working now!

Thanks everyone for their help!

php $_POST not working but $_GET is

I'm still not too sure what was causing it in the first place, but I have discovered that if I am making a request with a relative path then I have to omit the file extension. e.g. action="test-post" instead of action="test-post.php".

File extensions seem to be fine for $_GET and $_REQUEST if I am sending it via get (method="get"), but not for $_POST or $_REQUEST if I am sending it via post (method="post").

EDIT

This was something to do with the .htaccess file. I don't know much about that file, so I don't know exactly which bit was causing this issue.

Php POST not receiving any data

Everything looks fine but the submit href link, which you should replace with a Submit input type:

<a href="welcome.php">Submit</a>

to:

<input type="submit">
