php如何将if语句附加到按钮？

Question

我有一份声明;

if($game_set->issue_challenge()){echo "test";}else {"test failed";}

我有一个按钮：

<input type="submit" name="submit" id="submit" value="Submit" />

我希望能够说：if the button isset, then $values = $_POST['gamelist'] and if($game_set->issue_challenge()){echo "test";}else {"test failed";}

我在想像

这样的东西

if (isset($_POST['Submit'])) {
$values = $_POST['gamelist']
if($game_set->issue_challenge()){echo "test";}else {"test failed";}
}

任何想法？

感谢

假设您正在使用POST表单：

if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    if (isset($_POST['submit']) && ($_POST['submit'] == 'Submit')) {
       ... it was clicked
    }
}
