php条件语句（混合php的if语句和js编程）

<?php if (isset($_SESSION['account']) && $_SESSION['account'] !== null && isset($_SESSION['uid']) && $_SESSION['uid'] !== null): ?>var d = dialog({title: "收藏状态",content: `<input type='radio'>想看<input type='radio'>看过<input type='radio'>在看<input type='radio'>抛弃<input type='radio'>搁置<button onclick='addCollect()'>保存</button>`
                    })d.show();<?php else: ?>var d = dialog({title: "提示",content: "请先登录"})d.show();<?php endif; ?>}
