我在WordPress的WP-Pro-Quiz插件中有一个问题。有"单一答案选项"是可见的，但不是可选择的。我需要这些选项，我在想我也许可以让复选框发挥作用，然后得到我在测验中需要的结果。
是什么导致这些复选框"变灰"?
<?php
}
private function singleChoiceOptions($data)
{
$single = $data[0];
?>
<div class="postbox" id="singleChoiceOptions">
<h3 class="hndle"><?php _e('Single choice options', 'wp-pro-quiz'); ?></h3>
<div class="inside">
<p class="description">
<?php _e('If "Different points for each answer" is activated, you can activate a special mode.<br> This changes the calculation of the points',
'wp-pro-quiz'); ?>
</p>
<label>
<input type="checkbox" name="answerswerPointsDiffModusActivated"
value="1" <?php $this->checked($this->question->isAnswerPointsDiffModusActivated()); ?>>
<?php _e('Different points - modus 2 activate', 'wp-pro-quiz'); ?>
</label>
<br><br>
<p class="description">
<?php _e('Disables the distinction between correct and incorrect.', 'wp-pro-quiz'); ?><br>
</p>
<label>
<input type="checkbox" name="disableCorrect"
value="1" <?php $this->checked($this->question->isDisableCorrect()); ?>>
<?php _e('Disable correct and incorrect.', 'wp-pro-quiz'); ?>
</label>
<div style="padding-top: 20px;">
<a href="#" id="clickPointDia"><?php _e('Explanation of points calculation', 'wp-pro-quiz'); ?></a>
<?php $this->answerPointDia(); ?>
</div>
</div>
</div>
<?php
}
是灰色的，因为被disabled="enabled"禁用，即使值是enabled，输入也被禁用，任何值都将禁用输入，事实上，您可以只放置disable，它将被禁用，最新的浏览器只是读取disabled并禁用输入。删除disabled="enabled"，输入将被启用
我发现了，名称值与$this值不匹配，大写字母。插件作者一定错过了。希望这个函数能起作用。
