单选按钮窗体来更改PHP文件上的变量

Question

基本上我想要实现的是一个简单的PHP开/关，其中PHP代码被设置为0但有能力将其更改为1或0表单。

PHP file| $settingon = 1 //1 for active, 0 for inactive 
HTML file| <form action="php/settingfile.php"> 
     <input type="radio" name="settingon" value="1"> Active<br> 
     <input type="radio" name="settingon" value="0"> Inactive<br> 
     <button type="submit">Save Settings</button> 
     </form> 

Answer 1

如果您希望禁用输入：

<form action="php/settingfile.php"> 
    <input type="radio" name="settingon" <?php $settingon? "":"disabled" ?>> Active<br> 
    <button type="submit">Save Settings</button> 
</form> 

或创建显示输入一个类，只要你想：

<form action="php/settingfile.php"> 
    <input type="radio" name="settingon" class="<?php $settingon? "active":"inactive" ?>"> Active<br> 
    <button type="submit">Save Settings</button> 
</form>
