PHP: Send $_POST data to my Class?

I'm trying to send my $_POST data to a class of mine for processing... but it doesn't seem to matter how I send it, PHP is telling me:

Trying to get property of non-object

Class method:

public function test_me_out($postdata) {

    if(isset($postdata->price)) {

        return "the price was: " . $postdata->price . " …and this was added.开发者_如何转开发";

    } else {

        return "it's apparently not set...";

    }

}

$_POST is not an object. You should access its information using it as an array like $_POST['my_data'].

You can still do

$postData = new ArrayObject($_POST,ArrayObject::ARRAY_AS_PROPS);

Then $postData->price will work as expected to be.

How are you calling test_me_out? Like this?

test_me_out($_POST)

$_POST is an array, not an object. Therefore you can access the variables in your function like so:

$postdata['price']
