如何检查帖子中的提交是否为空？

How do i check in a http post if my submit form is empty? Since im saving it as base64 it wont let me post if the submit form is empty.

如果我的提交表单为空,我如何签入http帖子?由于我将其保存为base64,如果提交表单为空,它不会让我发布。

 $http.post('http://localhost/codeigniter/index.php/api/key/profile', {
            picture: $scope.file.base64
            username: $scope.username
        })

if (isset($_POST["picture"]) && !empty($_POST["picture"]))
{
    echo "Yes, picture is set";    
}
else
{  
    echo "N0, picture is not set";
}
