我正在为当前表单添加一些新的验证，我有三个单独的数组，我已经为选择框构建了，我需要确保用户至少进行了一个选择。此时，当用户填写表单时，它将提交并发送，但“必填”显示在表单中的空选择框旁边，即使通知说它已被发送，即使用户也会发送表单没有做出选择。我试着到处寻找解决方案，希望在这个问题上得到第二眼。提前感谢您的时间！
表单中的选择框 -
<?php echo $monthMessage; ?>
<select name="mm" class="select-form-style">
<option>
- Select Month -
</option>
<?php
foreach ($months as $month) {
$selected = (!empty($mm) && $mm == $month) ? 'selected="selected"' : '';
?>
<option value="<?php echo $month;?>" <?php echo $selected;?>>
<?php echo $month;?>
</option>
<?php
}
?>

答案 0 :(得分：0)
我不确定我是否理解了这个问题，但如果我对此有所了解，我的答案将是：
你的错误在那里：
if(!empty($_POST['mm']))
{
$monthMessage .= '<p class="errorClass">Required</p>';
}
因此，如果$_POST['mm'] 不是为空，则会显示“必需”。但是你有问题，这个值永远不会是空的：）
即使没有选择月份（“ - 选择月 - ”选中），导航器也会将选项标签的内容作为select的值发送;）
所以你有$_POST['mm'] = "- Select Month -"
你必须做这个测试：
// if mm sent and is not empty
if(isset($_POST['mm']) && !empty($_POST['mm']))
{
// if mm is in $months array
if(in_array($_POST['mm'], $months))
{
// this value is not accepted or "- Select Month -" selected
}
else
{
// seems a month is selected and into your $months list
}
}
else
{
// this case happens if don't send "mm" in post
// or if the value of mm is empty
}
顺便说一下，用stripslashes(trim($val));照顾这个值永远不会确定。
Btw2，您可以通过以下方式将makeSafe()应用于整个$_POST数组：
foreach($_POST as $k => $v)
{
$P[$k] = makeSafe($v);
}
然后调用您的数据，如$P['mm']
希望它有所帮助！
