PHP：不要将空白的表单字段邮寄 [英] PHP: Do not email form fields that are left blank

问题描述

目前，我正在制作一个非强制性字段的在线查询表单。

如果一个非强制性表单字段未填写，我想让它在处理的电子邮件中不会出现。 p>

例如;如果有人没有输入他们的电话号码，电话：$ atelephone组件不会通过。

  if（$ atelephone！=''）{
 echo电话：$ atelephone; 
} 
  

我认为代码应该有上面的东西，虽然我努力连接点。任何帮助将不胜感激。 （我希望这是有道理的）。

 <？php 
 
 //基本表单项
 
 $ asender = $ HTTP_POST_VARS ['name']。<。 $ HTTP_POST_VARS ['email']。>; 
 $ asubject =电子邮件查询：$ HTTP_POST_VARS ['subject']; 
 $ arecipient =[e-mail]; 
 
 / ******************************************* ************** / 
 //邮件表单变量// 
 
 $ aname = $ HTTP_POST_VARS ['name']; 
 $ aemail = $ HTTP_POST_VARS ['email']; 
 $ atelephone = $ HTTP_POST_VARS ['phone']; 
 $ asuburb = $ HTTP_POST_VARS ['郊区]; 
 $ aenquiry = $ HTTP_POST_VARS ['inquiry']; 
 
 mail（$ arecipient，$ asubject，

 =================== ====================== 
请注意：这是从网站生成的电子邮件
 
 == 
 
名称：$ aname 
电子邮件：$ aemail 
电话：$ atelephone 
郊区：$ asuburb 
 
消息：
 $ aenquiry 
 
 = =============================，FROM：$ asender）; 
 
 header（'Location：/thank-you.php'）; 
 
？> 
  

解决方案

你在正确的轨道上。最后一步是在最后一条消息中输入一个字符串：

  $ _ POST ['phone']？ 
 $ telephoneString =电话：$ _ POST ['phone']。\\\
：
 $ telephoneString =; 
  

（$ code> \\\
的字符串形成一个换行符。）

然后，输出消息中的字符串。它将为空，否则。

 foo bar baz 
 ========== =================================。 
 $ nameString。 
 $ emailString。 
 $ telephoneString。 
 $ downtownString; 
  

修改

<对于个人表单域，这可能会更好。然而，为了优雅，我更喜欢@mazzzzzz的解决方案。

Currently I am making an online enquiry form with a set of fields that are non-mandatory.

If a non-mandatory form field is not filled-in out, I would like to make it so that it doesn't come through in the processed email.

For instance; if someone does not enter their telephone number, the "Telephone: $atelephone" component does not come through.

if ($atelephone != '') { 
echo "Telephone: ".$atelephone;  
}

I figure the code should have something like above put in it, though I am struggling to connect the dots. Any help would be greatly appreciated. (I hope this makes sense).

<?php 

// Base form items

$asender = $HTTP_POST_VARS['name'] ." <". $HTTP_POST_VARS['email'] .">";
$asubject = "Email Enquiry: ".$HTTP_POST_VARS['subject'];
$arecipient = "[e-mail]";

/*******************************************************/
// Mail form variables //

$aname = $HTTP_POST_VARS['name'];
$aemail = $HTTP_POST_VARS['email'];
$atelephone = $HTTP_POST_VARS['telephone'];
$asuburb = $HTTP_POST_VARS['suburb'];
$aenquiry = $HTTP_POST_VARS['enquiry'];

mail("$arecipient","$asubject", 
"
===========================================
Please note: this is an email 
generated from the Website.
=========================================== 

Name: $aname
Email: $aemail
Telephone: $atelephone
Suburb: $asuburb

Message:
$aenquiry 

================================ ","FROM:$asender"); 

header('Location: /thank-you.php');

?>

解决方案

You're on the right track. The last step is make a string to input in your final message:

$_POST['telephone'] ?  
  $telephoneString = "Telephone: ".$_POST['telephone'] ."\n" : 
  $telephoneString = "";

(The \n at the end of the string makes a newline.)

Then, output the string in the message. It will be empty, or not.

  "foo bar baz
  ===========================================".
  $nameString.
  $emailString.
  $telephoneString.
  $suburbString;

Edit

This may work better for individual form fields. However, for elegance, I prefer the solution from @mazzzzzz.
