Question

我拿了一个我总是使用的标准表格，其中包括评论。对于这个网站，我不需要评论，所以我只留下电子邮件和网址。当我删除与PHP文件中的注释相关的所有内容时，它会显示一个空白页面，甚至不会出现错误。

以下是代码：

<?php
if(isset($_POST['email'])) {

    // CHANGE THE TWO LINES BELOW
    $email_to = "email@email.com";

    $email_subject = "NEW CONTACT";


    function died($error) {
        // your error code can go here
        echo "We are very sorry, but there were error(s) found with the form you submitted. ";
        echo "These errors appear below.<br /><br />";
        echo $error."<br /><br />";
        echo "Please go back and fix these errors.<br /><br />";
        die();
    }

    // validation expected data exists
    if(!isset($_POST['email']) ||
        !isset($_POST['url'])) || {
        died('We are sorry, but there appears to be a problem with the form you submitted.');       
    }

    $email_from = $_POST['email']; // required
    $url = $_POST['url']; // not required


    $error_message = "";
    $email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';
  if(!preg_match($email_exp,$email_from)) {
    $error_message .= 'The Email Address you entered does not appear to be valid.<br />';
  }


  if(strlen($error_message) > 0) {
    died($error_message);
  }
    $email_message = "Form details below.\n\n";

    function clean_string($string) {
      $bad = array("content-type","bcc:","to:","cc:","href");
      return str_replace($bad,"",$string);
    }


    $email_message .= "Email: ".clean_string($email_from)."\n";
    $email_message .= "url: ".clean_string($url)."\n";



// create email headers
$headers = 'From: '.$email_from."\r\n".
'Reply-To: '.$email_from."\r\n" .
'X-Mailer: PHP/' . phpversion();
@mail($email_to, $email_subject, $email_message, $headers);  
?>

<!-- place your own success html below -->

Success

<?php
}
die();
?>

你的if条件中有额外的||。删除它，它应该工作。

if(!isset($_POST['email']) ||
    !isset($_POST['url'])) || {
                          ^^^^
    died('We are sorry, but there appears to be a problem with the form you submitted.');       
}
