Question

我正在尝试将切换开关的值发送到我的URL并使用Php检索它。代码正在运行。问题是每次我更改页面或使用后退按钮我需要重新加载页面，以便切换开关工作，但停留在同一页面是不起作用。我做错了什么？

这是我的代码：

<?php
    $status_water = $_GET['water_swicth'];
    $status_light = $_GET['light_swicth'];
    $status_air   = $_GET['air_swicth'];

    if ($status_water == "on")
        { $water_on = "selected"; 
          $file = fopen("light.json", "w") or die("can't open file");
          fwrite($file, '{"water": "on", "light":off, "air":off}');
          fclose($file);
        }
    if ($status_water == "off") {  
      $file = fopen("light.json", "w") or die("can't open file");
          fwrite($file, '{"water": "off", "light":"off", "air":off}');
      fclose($file);
    }
    ?>
