PHP表单:仅填写字段的成功电子邮件 [英] PHP form: Success email with only filled fields

问题描述

过去为此苦苦挣扎了一段时间.基本上，我有6个字段，分别是姓名，电子邮件，电话，位置，日期和预算.名称和电子邮件是唯一必填字段.收到电子邮件后，我还会看到其余字段.可以仅接收已填写的字段吗?

Been struggling with this for some time now. Basically I have 6 fields, name, email, phone, location, date and budget. Name and email are the only required fields. When I get the email I see rest of the fields as well. Is it possible to receive only fields that have been filled?

这是代码；

<?php
// get posted data into local variables
$EmailFrom = "[e-mail]";
$EmailTo = "[e-mail]";
$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=#\">";
}
?>

推荐答案

使用空检查值是否为是否发布:

Use empty to check if a value was posted or not:

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

然后，如果未填写，随后的 $ Phone 将为false，您可以执行以下操作:

Then later $Phone will be false if it wasn't filled in and you can do this:

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