Question

我已成功设法显示并发送所有文本字段值，但我在检查选择了日，月和年时遇到问题，如果没有，则显示错误消息。选择并通过验证后，我将使用表单脚本发送值。

以下是我所做的，如果有人可以帮我验证下拉选项，请将值发送到电子邮件地址，并在通过提交后重定向到“谢谢”页面我非常感谢。

<form name="form1" e class="membership-form membership-form-stage-two" method="post" action="form-one.php">
    <div class="half">
        <h4>First Name</h4>

    <div class="half lasthalf">

Answer 1

在检查companyname

后，只需添加此行

if(!checkdate($_POST['month'],$_POST['day'],$_POST['year'])){
      $errors .= 'Please enter a valid DOB<br/><br/>';
}

Answer 2

如果<select没有name="xx"属性，则该字段的值不会回发到服务器。因此，为每个人添加一个名称。

您还必须在value=""中添加一个值，因为这是实际发回服务器的值而不是<option>1</option>标记之间的值。

<h4>Date of Birth</h4>
<select class="day" name="day">
    <option>Day</option>
    <option value="0">Select day</option>
    <option value="1">1</option>
    <option value="2">2</option>
</select>

<select class="month" name="month">
    <option>Month</option>
    <option value="0">Select month</option>
    <option value="1">January</option>
    <option value="2">February</option>
    ....
</select>

<select class="year" name="year">
    <option>Year</option>
    <option value="0">Select year</option>
    <option value="2001">2001</option>
    <option value="2001">2002</option>
    ....
</select>

当你来验证时记住，现在你有一个值=“”设置，你将总是得到一个值作为下拉菜单自动选择列表中的第一个值，除非另有指示。

现在我在每个列表中添加了一个值为“0”的项目。当您确认已选择某个条目时，您可以测试该

if ( $_POST['day'] > 0 ) // An item has been selected

依此类推所有日期字段。

PHP $ _POST下拉
