單選按鈕和會話，如何獲取價值並將其用作會話變量

Question

如何獲取單選按鈕的值並在會話中使用該值？

<input type="radio" name="minor" id="minor" group="underage" class="minor_yes" value="yes" />Yes<br /> 
<input type="radio" name="minor" id="minor" group="underage" class="minor_no" value="no" />No<br /> 

<div class="underage <?= isset($_SESSION['minor']) ? "style=\"display: block;\"" : "style=display: none;\"" ?>"> 
      <label>Guardian 1</label> 
      <input type="text" name="guardian1" id="guardian1" value="<?php echo stickyText('guardian1');?>" /> 
      <label>Guardian 2</label> 
      <input type="text" name="guardian2" id="guardian2" value="<?php echo stickyText('guardian2');?>" /> 
     </div> 

，你可以看到調用的代碼名稱爲「未成年人」，但即使沒有被選中它仍然會顯示格，無論這個值的，我需要的價值傳遞到我的isset（$ _ SESSION [ 'minor']）參數，這將如何實現？

@Xavier：嘗試 -

<input type="radio" name="minor" id="minor" group="underage" class="minor_yes" value="yes" />Yes<br /> 
<input type="radio" name="minor" id="minor" group="underage" class="minor_no" value="no" />No<br /> 

<div class="underage"<?php echo isset($_SESSION['minor']) && $_SESSION['minor'] != 'no' ? 'style="display: block;"' : 'style="display: none;"' ?>> 
    <label>Guardian 1</label> 
    <input type="text" name="guardian1" id="guardian1" value="<?php echo stickyText('guardian1'); ?>" /> 

    <label>Guardian 2</label> 
    <input type="text" name="guardian2" id="guardian2" value="<?php echo stickyText('guardian2'); ?>" /> 
</div>
