Question

我正在使用PHP脚本根据表单中的信息生成电子邮件。表单的行数可变。

我已将表单中每行输入的名称转换为数组，方法是在名称后添加[]，以便所有行中的数据都可用于生成电子邮件。

然而，我不知道如何构建PHP，以便它可以生成一封电子邮件中包含正确行数的电子邮件。

目前我刚刚设置PHP以读取数组中每个输入的前5个项目，并使用这些项目构建电子邮件的正文。这种方法的问题在于，如果用户添加超过5行，则数据将丢失，如果少于5行，则电子邮件中将出现“名称，电子邮件，电话”中不必要的文本。

我想知道是否有办法让PHP为任意数量的行读取数组，并生成一个只有正确行数的电子邮件？我已经包含了PHP，如下所示。

谢谢，

尼克

Answer 1

执行类似这样的操作，迭代其中一个数据数组：

foreach($_POST['name'] as $i => $name){
   echo $name;
   echo $_POST['email'][$i];
   echo $_POST['telephone'][$i];
}

除了打印数据外，不要将其添加到将成为电子邮件正文的字符串中。

Answer 2

不要将每个变量分配给唯一变量，而只需将它们放入数组中。

$body = '';
$row_count = count($_POST['name']);

for($i = 0; $i < $row_count; $i++)
{
  // variable sanitation...
  $name = trim(stripslashes($_POST['name'][$i]));
  $email = trim(stripslashes($_POST['email'][$i]));
  $telephone = trim(stripslashes($_POST['telephone'][$i]));

  // this assumes name, email, and telephone are required & present in each element
  // otherwise you will have spurious line breaks. 
  $body .= $name . "\n\n" . $email . "\n\n" . $telephone . "\n\n";
}

// send email 
$success = mail($emailTo, $subject, $body, "From: <$EmailFrom>");

同样在纯粹的文体上，你的变量应该以小写字母开头。
