一段时间以来一直在为此苦苦挣扎。基本上我有 6 个字段，姓名、电子邮件、电话、位置、日期和预算。姓名和电子邮件是唯一必填字段。当我收到电子邮件时，我也会看到其他字段。是否可以只接收已填写的字段？

这是代码；

<?php
// get posted data into local variables
$EmailFrom = "email@email.com";
$EmailTo = "email@email.com";
$Subject = "My form";
$Name = Trim(stripslashes($_POST['Name'])); 
$Email = Trim(stripslashes($_POST['Email'])); 
$Phone = Trim(stripslashes($_POST['Phone']));

$Location = Trim(stripslashes($_POST['Location'])); 
$Date = Trim(stripslashes($_POST['Date']));
$Budget = Trim(stripslashes($_POST['Budget'])); 

// validation
$validationOK=true;
if (!$validationOK) {
  print "<meta http-equiv=\"refresh\" content=\"0;URL=#\">";
  exit;
}

$userip = ($_SERVER['X_FORWARDED_FOR']) ? $_SERVER['X_FORWARDED_FOR'] : $_SERVER['REMOTE_ADDR'];

// prepare email body text
$Body = "";
$Body .= "Location: "; $Body .= $Location; $Body .= "\n";
$Body .= "Date: "; $Body .= $Date; $Body .= "\n";
$Body .= "Budget: "; $Body .= $Budget; $Body .= "\n";

$Body .= "Name: "; $Body .= $Name; $Body .= "\n";
$Body .= "Email: "; $Body .= $Email; $Body .= "\n";
$Body .= "Phone: "; $Body .= $Phone; $Body .= "\n";
$Body .= "User's IP: ". $userip;

// send email 
$success = mail($EmailTo, $Subject, $Body, "From: <$EmailFrom>");

// redirect to success page 
if ($success){
  print "<meta http-equiv=\"refresh\" content=\"0;URL=#\">";
}
else{
  print "<meta http-equiv=\"refresh\" content=\"0;URL=#\">";
}
?>

使用empty检查值是否已发布：

$Phone = !empty($_POST['Phone']) ? trim(stripslashes($_POST['Phone'])) : false;

$Phone如果没有填写，那么稍后将是错误的，您可以这样做：

if($Phone)
    $Body .= "Phone: "; $Body .= $Phone; $Body .= "\n";

您可以简单地检查该值是否存在。你可以这样做：

if (!empty($Location) { $Body .= "Location: "; $Body .= $Location; $Body .= "\n"; }

等等等等。这就是说如果位置不为空，则执行该代码

是的，只需在将字段连接到正文之前添加一个检查，例如：

if(!$Location)
{
    $Body .= "Location: "; $Body .= $Location; $Body .= "\n";
}
/*You can also use empty like: */
if(!empty($Date))
{
    $Body .= "Location: "; $Body .= $Date; $Body .= "\n";
}
/*Continue here*/

if (isset($_POST['phone'] && !empty($_POST['phone']){
    $phone = $_POST['phone'];
    //add $phone to email body
}
