Despite its name, the $_POST array won’t always contain your POST data and can be easily found empty.
It’s because PHP only parses a POST payload automatically when it has a content type of application/x-www-form urlencoded or multipart/form-data.
let’s take an example. Assume that we make a server request with a jQuery.ajax() call as follows:
$.ajax({
url: 'http://www.somesite.com/some/path',
method: 'post',
data: JSON.stringify({a: '1', b: '2'}),
contentType: 'application/json'
});
Now if on the server side, we dump the $_POST array:
var_dump($_POST);
Surprisingly, the result will be:
array(0) { }
It’s because the content type is json, not multipart/form-type.
If we want to achieve this, we need to manually decode the JSON data and override the $_POST variable like this:
// php
If we want to achieve this, we need to manually decode the JSON data and override the $_POST variable like this:
// php
$_POST = json_decode(file_get_contents('php://input'), true);
Now if we dump the $_POST array, we can see that it includes the POST payload;
array(2) { [“a”]=> string(1) “a” [“b”]=> string(1) “b” }
