为什么我的Angular POST请求PHP页面没有设置POST数组？

Question

I have a angular post that sends to my php file, but in the PHP file, I cannot access anything from the post variable. It returns my SUCCESS string, but nothing after that, so my return on the post is "SUCCESS - - - - - " where the data should be between the dashes.

JSON/JS object:

DESCRIPTION: "123321"
LOCATION: "ab_calgary_eighth_ave_pl"
NAME: "123321"
QUANTITY: 123321
TYPE: "cycle"

Angular POST Code:

        $scope.insertNewInventoryItem = function()
        {
            if(typeof ($scope.newItem.LOCATION) == 'undefined')
                alert("LocationCannot Be Empty.  Please Select An Option From The Drop Down.");

            else if(typeof ($scope.newItem.TYPE) == 'undefined')
                alert("Type Cannot Be Empty.  Please Select An Option From The Drop Down.");

            else
            {
                $http.post("dataaccess/addnewinventory.php", $scope.newItem).then(onAddNewComplete, onAddNewError);
            }
        }

PHP Page attempting to find the posted values:

<?php
$con = mysqli_connect("localhost", "dbadminuser", "password", "database_demo_inventory");

// Check connection
if (mysqli_connect_errno())
{
    echo "FAIL - Failed to connect to MySQL: " . mysqli_connect_error();
}
else
{
    echo "SUCCESS - " . $HTTP_POST_VARS['newItem.NAME'] . " - " . $HTTP_POST_VARS['TYPE'] . " - " . $HTTP_POST_VARS["QUANTITY"] . " - " . $HTTP_POST_VARS . " - " . $_POST[0];
}

mysqli_close($con);
?>

Picture of return data from the request (see PHP code for where SUCCESS is coming from):

Why can I not access the post variables? Am I missing something here?

Answer 1

For decoding the PHP, I used the following code, which gave me direct access into the POST data, which in my case was JSON. Apparently JSON is a unsupported data structure, so PHP failed to parse it automatically into the POST array:

$jsonText = file_get_contents('php://input');
$decodedText = html_entity_decode($jsonText);
$myArray = json_decode('[' . $decodedText . ']', true);

Explanation: Line 1 gets the raw data that was sent over from the request (in this case it was from the Angular Controller posted in the OP. Line 2 decodes the JSON array grabbed in step one, correctly forming it to parse later. Note that in this case, steps one and two both return the exact same looking object. Line 3 takes the formatted JSON data and decodes it into a PHP array. Now you can use the following to access parts of the array:

$myvar = $myArray[0]["SOME_VARIABLE"];

Thanks for the answers guys!
