我的约会表格有问题。当客户填写表单，但必填字段留空时，此字段将收到错误消息。这很好用。问题是这个页面上的不同选择菜单会得到一个奇怪的结构。遇到此问题，将发送错误的日期。如果你想要，你可以在这里测试表格; http://www.o-vita.nl/afspraak.php

以下是发送邮件的脚本：

$_SESSION['aanhef'] = $aanhef;

我现在有这样的话：
<?php $days = array(
1 => 1,
2 => 2,
3 => 3,
etc
etc
// ...
);
echo '<select name="dag_nummer" type="text" class="text_dag_nummer">' . "\n";
foreach ($days as $value => $text) {
echo '<option value="' . $value . '"';
if (isset($_POST['dag_nummer']) && $_POST['dag_nummer'] == $value) {
echo ' selected="selected"';
}
echo '>' . $text . "</option>\n";
}
echo "</select>\n";
?>
但是，它仍会在下拉框之后显示所选值，而不是选择所需的值... 请参阅我的屏幕截图：http://piclair.com/data/gpjal.jpg
答案 0 :(得分：1)
看起来您希望错误页面显示用户以前为下拉菜单选择的选项。这应该使用以下方法完成：
<option value="10" selected="selected">10</option>
您需要以编程方式处理此选择：
$days = array(
1 => 1,
// ...
);
echo '<select name="dag_nummer" type="text" class="text_dag_nummer">' . "\n";
foreach ($days as $value => $text) {
echo '<option value="' . $value . '"';
if (isset($_POST['dag_number']) && $_POST['dag_number'] == $value) {
echo ' selected="selected"';
}
echo '>' . $text . "</option>\n";
}
echo "</select>\n";
这应该取代您的echo (isset($_SESSION['dag_number'])) ...逻辑。
还要注意这个构造的<select>元素的结构 - <option>元素嵌套在里面。
答案 1 :(得分：0)
在名为“aanhef”的<select>元素之后，您有这一行：
<?php echo (isset($_SESSION['aanhef'])) ? $_SESSION['aanhef'] : ""; ?>
该行在菜单后打印一些附加文本，通过截图判断 - 看起来你不想要。我认为您可能希望测试每个<option>元素以查看它是否与$ _SESSION ['aanhef']值匹配，而不是在菜单之后打印该文本，如果是，则追加属性selected="selected"放入该标记。
另请注意，您的<select>元素当前在结束标记内部有一个斜杠，如下所示：<select />。
