我有这个简单的表格在 php 中发送电子邮件。发送 php 代码中这个表单的好处是我不必写出所有字段名称。例如，我不必写这个：

$msg .= "$_POST[ContactName]     Contact Name:     ContactName\n"

在我的代码中，我只需要写：

foreach ($_POST as $Field=>$Value) { 
$body .= "$Field: $Value\n";

该表格目前运行良好。它目前正在发送：

ContactName: name here
BusinessName: business name here
EmailAddress: email@email.com
Email_Confirmation: 
PhoneNumber: 714-555-5555

但是，我希望这种情况发生：如果某个字段留空或网络用户未填写某个字段框，则表单不应发送此字段。例如：网络用户决定不填写 ContactName 和/或 BusinessName。所以表单应该只发送这种格式：

EmailAddress: email@email.com
Email_Confirmation: 
PhoneNumber: 714-555-5555

注意到没有提及 ContactName: 和 BusinessName:

请帮忙！我会很感激。-米歇尔哈。

这是php发送代码：

if the Email_Confirmation field is empty
if(isset($_POST['Email_Confirmation']) && $_POST['Email_Confirmation'] == ''){

    // put your email address here
    $youremail = 'bomandty@gmail.com';

    // prepare a "pretty" version of the message
    $body .= "Thank you for your request. We will get back with you soon.";
    $body .= "\n";
    $body .= "\n";
    foreach ($_POST as $Field=>$Value) { 
    $body .= "$Field: $Value\n"; 
    $body .= "\n";
    }

    $CCUser = $_POST['EmailAddress'];

    // Use the submitters email if they supplied one
    // (and it isn't trying to hack your form).
    // Otherwise send from your email address.
    if( $_POST['EmailAddress'] && !preg_match( "/[\r\n]/", $_POST['EmailAddress']) ) {
      $headers = "From: $_POST[EmailAddress]";
    } else {
      $headers = "From: $youremail";
    }

    // finally, send the message
    mail($youremail, 'subject line here', $body, $headers, $CCUser );

}

// otherwise, let the spammer think that they got their message through

为您添加检查 foreach

if(empty($Value)) continue;

并将表单中的默认值更改为占位符
