php 表单值不显示

Question

我的表单不会显示这些值，除非我将它们添加到 required = 数组并且并非所有内容都是必需的。因此，公司名、姓氏和电子邮件将显示在发送的电子邮件中，但不会显示电话和消息(我还有其他字段要添加)。

这是我的代码:

<?php

if(!$_POST) exit;

$email = $_POST['email'];

//$error[] = preg_match('/\b[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b/i', $_POST['email']) ? '' : 'INVALID EMAIL ADDRESS';
if(!eregi("^[a-z0-9]+([_\\.-][a-z0-9]+)*" ."@"."([a-z0-9]+([\.-][a-z0-9]+)*)+"."\\.[a-z]{2,}"."$",$email )){
    $error.="Invalid email address entered";
    $errors=1;
}

if($errors==1) echo $error;
else{
    $values = array('firname','lasname','email','phone','message');
    $required = array('firname','lasname','email',);

    $your_email = "aasdasd@email.com";
    $email_subject = "Reservations Form: ".$_POST['subject'];
    $email_content = "new reservation:\n";

    foreach($values as $key => $value){
        if(in_array($value,$required)){
            if ($key != 'subject' && $key != '') {
                if( empty($_POST[$value]) ) { echo 'PLEASE FILL IN REQUIRED FIELDS'; exit; }
            }
            $email_content .= $value.': '.$_POST[$value]."\n";
        }
    }

    if(@mail($your_email,$email_subject,$email_content)) {
        header('Location: http://www.example.com/test/reservation-submission.html');
    } else {
        echo 'ERROR!';
    }
}
?>`

Answer 1

更改此部分:

foreach($values as $key => $value){
  if(in_array($value,$required)){
    if ($key != 'subject' && $key != '') {
      if( empty($_POST[$value]) ) { echo 'PLEASE FILL IN REQUIRED FIELDS'; exit; }
    }
    $email_content .= $value.': '.$_POST[$value]."\n";
  }
}

为了...

foreach($values as $key => $value){
  if(in_array($value,$required)){
    if ($key != 'subject' && $key != '') {
      if( empty($_POST[$value]) ) { echo 'PLEASE FILL IN REQUIRED FIELDS'; exit; }
    }
  }
  $email_content .= $value) .': '.$_POST[$value])."\n";
}

过于简单化，您将获取 $values 数组中的每个项目并在表单中搜索它。如果它在 $required 列表中，则检查它是否为空。如果它是空白的，那么它会显示一条错误消息。否则，您希望将其添加到将通过邮件 ($email_content) 发送的消息中。

以前，“将其添加到电子邮件内容”部分仅在“如果需要”循环中执行。我将其向下移动，使其成为“for each value”循环的一部分。
