php - why can't we access values on server side in POST request? -

-

i tried send request jquery ajax contenttype 'text/plain'. unable access values on server side. accessing values using $_post array in php file. why happening.

jquery ajax code:

$.ajax({      type: "post",      data: {o_pass:o_pass,n_pass:n_pass},      url: "changepass",      success: function(response) { alert(response); }  });

server side:

$old_pass = $_post['o_pass'];  $new_pass = $_post['n_pass'];

because post requests should have content type of application/x-www-form-urlencoded or multipart/form-data server knows dealing with.

what reason sending request plain text?
