Question

关于PHP电子邮件脚本必须有数千个问题，但我仍然没有找到答案。我查看了php网站，但它也没有真正帮助。

基本上我的脚本会验证输入并相应地显示错误消息，但是当我添加脚本的第二部分来处理发送电子邮件时，页面显示500错误。这是我的代码。目前该电子邮件尚未设置为正确的电子邮件，但我知道这不是问题所在。

<?php include('includes/header.php'); 

$yourEmail = "hello@example.com";
$formSubject = "Message recieved from enquiry form";


if( isset( $_POST["submit"])) {

//Validate the data
function validateFormData( $formData ) {
    $formData = trim( stripslashes(htmlspecialchars( $formData )));
    return $formData; 
}


//check to see if inputs are empty
// create variables with form data
// wrap the data with our function

if( !$_POST['name']) {
    $nameError = "Please enter your name <br />";  
} else {
    $name = validateFormData( $_POST["name"]);
}
if( !$_POST['email'] || !preg_match("/^\S+@\S+$/", $email)) {
    $emailError = "Please enter a valid email address <br />";  
} else {
    $email = validateFormData( $_POST["email"]);
}                
if( !$_POST['enquiry']) {
    $enquiryError = "Please enter your enquiry <br />";  
} else {
    $enquiry = validateFormData( $_POST["enquiry"]);
}

代码工作正常至此为止;

//Check to see if submit is set
//Check to make sure errors don't exist
//Send the email
// Redirect user to success.html  


if ( isset( $_POST["submit"]) && (empty($emailError, $nameError, $enquiryError))) {

$to = $yourEmail;
$subject = $formSubject;  
$headers = 'From:'. $name . "\r\n".
    'Reply-To: '. $email . "\r\n".
    'X-Mailer: PHP/' . phpversion();

$body = 

'The person that contacted you was '.$name.'
Email: '.$email.'
URL: '.$url.'
Message: '.$enquiry.''.

mail($yourEmail, $formSubject, $body, $headers);



header("Location: success.html");


}
}

?>

这是HTML表单，我确信这是好的，考虑到PHP工作到某一点并正确显示错误消息。我知道我有PHP_SELF很多人都说不使用但是如果有错误我想留在页面上，只有在发送电子邮件时才重定向。

<form id="contactForm" method="POST" action="<?php echo   htmlspecialchars($_SERVER["PHP_SELF"]);?>">

<label for="name">Name&nbsp;<span class="asterisk">*</span></label> 
 <input type="text" name="name" id="name" value="<?php echo $name;?>"tabindex="1"/>
<span class="error"><?php echo $nameError; ?></span>

<label for="email">Email&nbsp;<span class="asterisk">*</span></label> 
 <input type="email" name="email" id="email" value="<?php echo $email;?>" tabindex="2"/>
  <span class="error"><?php echo $emailError; ?></span>  
  <span class="error"><?php echo $emailValidError; ?></span>  

 <label for="url">Website</label> 
  <input type="url" name="url" id="url" value="<?php echo $url;?>" tabindex="3"/>


 <h3>Tell us about your project&nbsp;</h3><br />

 <textarea name="enquiry" id="enquiry" tabindex="4"><?php echo $enquiry;?></textarea>
   <span class="error"><?php echo $enquiryError; ?></span>  

   <button type="submit" id="submit" name="submit" value="submit" >Submit</button>

 </form>

Answer 1

你的问题在这里：

empty($emailError, $nameError, $enquiryError)

empty只接受一个param，你传递它3.将条件更改为：

if( isset( $_POST["submit"]) && ( empty($emailError) && empty($nameError) && empty($enquiryError) ))

或者如果你想缩短那个条件

 $Errors = $emailError.$nameError.$enquiryError;
 if( isset( $_POST["submit"] ) &&  empty( $Errors ) )

Answer 2

这就是出现错误的原因。第一个语法错误然后（空（$ emailError，$ nameError，$ enquiryError））不是一个好主意。我会做这样的事情：

 $err=0;
 if( !$_POST['name']) {
         $nameError = "Please enter your name <br />";  
         $err++;
       } else {
        $name = validateFormData( $_POST["name"]);
         $err++;
       }

 if( !$_POST['email'] || !preg_match("/^\S+@\S+$/", $email)) {
       $emailError = "Please enter a valid email address <br />"; 
       $err++; 
       } else {
        $email = validateFormData( $_POST["email"]);
  }        


 if( !$_POST['enquiry']) {
      $enquiryError = "Please enter your enquiry <br />";  
      $err++;
      } else {
      $enquiry = validateFormData( $_POST["enquiry"]);
    } 

   if ( isset( $_POST["submit"]) && $err==0) {
        //your code here//
        //and i would do like this//
        $result_mail_send = mail($yourEmail, $formSubject, $body, $headers);
        if($result_mail_send==true){
              //redirect to success
        }else{
              //redirect to fail//
        }

    }
