trouble with dir management and file uploading

[Sabmin]

Trying to a. check if dir exists if not create it, and b. save an uploaded file to that directory.  Nothing however is working but I'm pulling no errors, heres the code:

 

$test_pic = $_POST['test_pic'];
// I've also tried       $test_pic = $_FILES["test_pic"];     : with no success
if (is_uploaded_file($test_pic)) {
		if (!file_exists("tests/uploads/" . $test_name . "/")) {
			$create_test_folder = (mkdir("tests/uploads/" . $test_name));
			if (!$create_test_folder) {
				echo "cant create folder";
				die;
			}
		}
		$target_path = ("tests/uploads/" . $test_name . "/" . $test_name . "_1");
		if (($_FILES["test_pic"]["type"] == "image/gif")
	 	 || ($_FILES["test_pic"]["type"] == "image/jpeg")
		 || ($_FILES["test_pic"]["type"] == "image/jpg")
		 || ($_FILES["test_pic"]["type"] == "image/png")
		 && ($_FILES["test_pic"]["size"] < 50000)) {
			if (!copy($test_pic, $target_path)) {
				echo "cant copy picture";
				die;
			}
		} else {
			echo "file type or size bad";
			die;
		}
	}

 

and I understand its not at all public-safe but I'm just wanting to get it to work before I throw in the security.  Thanks for the help!

try basic debug?

 

if (is_uploaded_file($test_pic)) {
    // blah blah blah

} else {
     echo "$test_pic is not an uploaded file!";
}
