晚上好, 对于我的网站,我使用的是邮件表格。显然它是说消息已发送,尽管没有填写任何内容。我也没有收到电子邮件。 我必须在代码中包含哪些内容,以便在发送之前检查,是否填写了电子邮件,主题和消息? 谢谢你的帮助!
<?php
if (isset($_REQUEST['email']))
//if "email" is filled out, send email
{
//send email
$email = $_REQUEST['email'] ;
$subject = $_REQUEST['subject'] ;
$message = $_REQUEST['message'] ;
mail("***.****@gmail.com", $subject,
$message, "From:" . $email);
echo "Thank you for using our mail form. We will reply as soon as possible.";
}
else
{
echo "<form method='post' action='mailform.php'>
Email: <br> <input name='email' type='text'><br>
Subject: <br> <input name='subject' type='text'><br>
Message:<br>
<textarea name='message' rows='15' cols='40'>
</textarea><br>
<input type='submit'>
</form>";
}
?>

if (isset($_REQUEST['submit']){
echo 'display error here';
}
echo "<form method='post' action='mailform.php'>

您需要检查$_REQUEST['email'] != ''
而不是isset($_REQUEST['email'])
,并对其他变量执行相同操作。
函数isset()
检查变量是否具有任何值,包括变量是否定义为空。
