HOW to get $_POST variable into my CLASS?

Probably a newbie question, but then I'm learning on the fly:

Within the following code, I need to name $targetname and $imagelocation come from the $_POST variable coming in... I KNOW I can't define these variables properly the way I'm trying to, but am a bit stumped... help anyone?

class PostNewTarget{

//Server Keys
private $access_key     = "123456";
private $secret_key     = "142356";

private $targetName     = $_POST['the_target'];
private $imageLocation  = $_POST['the_image'];

function PostNewTarget(){

    $this->jsonRequestObject = json_encode( array( 'width'=>300, 'name'=>$this->targetName , 'image'=>$this->getImageAsBase64() , 'application_metadata'=>base64_encode($_POST['myfile']) , 'active_flag'=>1 ) );

    $this->execPostNewTarget();

}
...

Treat it as a normal variable and put it in a constructor or mutator or argument of a function if it's only needed in that function. Here is an example using a constructor, but the logic is the same in every case.

class Example {
    public $varFromPOST;
    public $name

    public function __construct($var, $name) {
        $this->varFromPOST = $var
        $this->name = $name
    }   
 }

Then in your index.php:

$_POST['foo'] = 100;
$userName = 'Bob';
$Example = new Example($_POST['foo'], $userName);

Seems straightforward, if I didn't misunderstand your question.

You need to initialize first your class properties

You can set $_POST values to your class properties when you create your class object using constructor, or you can set just when you need to get these values, I made it in your example

class PostNewTarget{

//Server Keys
private $access_key     = "123456";
private $secret_key     = "142356";

private $targetName     =  "";
private $imageLocation  = "";

//you can give class variables values in the constructor
//so it'll be setted right when object creation
function __construct($n){
    $this->targetName = $_POST['the_target'];
    $this->imageLocation = $_POST['the_image'];
}

function PostNewTarget(){
    //or you set just only when you need values
    $this->targetName = $_POST['the_target'];
    $this->imageLocation = $_POST['the_image'];

    $this->jsonRequestObject = json_encode( array( 'width'=>300, 'name'=>$this->targetName , 'image'=>$this->getImageAsBase64() , 'application_metadata'=>base64_encode($_POST['myfile']) , 'active_flag'=>1 ) );

    $this->execPostNewTarget();

} 
}

Pass into the method:

function PostNewTarget($targetName, $imageLocation)

Then call with:

PostNewTarget($_POST['the_target'], $_POST['the_image'])

You could possibly add in the constructor, but I wouldn't:

public function __construct() {
    $this->targetName = $_POST['the_target'];
    $this->imageLocation = $_POST['the_image'];
}
