php - 单选按钮和会话，如何获取值并用作会话变量

Question

例如，我将如何获取单选按钮的值并在我的会话中使用它；

<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>

如您所见，代码将名称称为“次要”，但即使选择否，它仍会显示 div，无论值如何，我都需要将值传递给我的 isset($_Session['minor']) 参数，这将如何实现？

@Xavier：试试——

<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>
