联系我们的电子邮件PHP错误

Question

我试图做一个联系表，我得到这个通用错误：

Internal Server Error 

The server encountered an internal error or misconfiguration and was unable to complete your request. 

Please contact the server administrator, [email protected] and inform them of the time the error occurred, and anything you might have done that may have caused the error. 

More information about this error may be available in the server error log. 

我无法弄清楚如何得到它实际登录或回声错误。这是我的PHP文件：

<?php 
ini_set('display_errors', true); 
ini_set('log_errors', true); 
error_reporting(E_ALL); 
ini_set('error_log', 'php.log'); 
$field_fname = $_GET['fname'] ; 
$field_lname = $_GET['lname'] ; 
$field_bname = $_GET['bname'] ; 
$field_email = $_GET['email'] ; 
$field_address = $_GET['address'] ; 
$field_city = $_GET['city'] ; 
$field_state = $_GET['state'] ; 
$field_zip = $_GET['zip'] ; 
$field_country = $_GET['country'] ; 
$field_comments = $_GET['comments'] ; 

$mail_to = '[email protected]'; 
$subject = 'Message from a site visitor '.$field_fname .$field_lname; 

$body_message = 'From: '.$field_fname .$field_lname 'at' .$field_bname "\n"; 
$body_message = 'E-mail: '.$field_email "\n"; 
$body_message = 'Address:'.$field_address "\n"; 
$body_message = 'City:'.$field_city "\n"; 
$body_message = 'State:'.$field_state "\n"; 
$body_message = 'Zip Code:'.$field_zip "\n"; 
$body_message = 'Country:'.$field_country "\n"; 
$body_message = 'Message: '.$field_comments; 

$headers = 'From: '.$field_email."\r\n"; 
$headers .= 'Reply-To: '.$field_email."\r\n"; 

$mail_status = mail($mail_to, $subject, $body_message, $headers); 

if ($mail_status) { ?> 
    <script language="javascript" type="text/javascript"> 
     alert('Thank you for the message. We will contact you shortly.'); 
     window.location = 'index.html'; 
    </script> 
<?php 
} 
else { ?> 
    <script language="javascript" type="text/javascript"> 
     alert('Message failed. Please, send an email to [email protected]'); 
     window.location = 'index.html'; 
    </script> 
<?php 
} 
?> 

我不知道我在做什么是错的。如果有人能够帮助我找到错误或指示我登录或回应错误，我会非常感激。

感谢

Answer 1

构建$body_message当你丢失级联器的堆（.）。

$body_message = 'From: '.$field_fname .$field_lname.'at' .$field_bname."\n"; 
$body_message = 'E-mail: '.$field_email."\n"; 

等等。

任何体面的编辑器都会在保存文件之前将其标记为错误。

我把你的代码在一个名为so.php 文件，它有一个语法错误行20

PHP Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING in so.php on line 20

Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING in so.php on line 20

Errors parsing so.php

你错过在之后的第20行上的连接点之前和之前'at'

您可能有兴趣在本地安装php（例如简单的wamp），然后将php可执行文件放在您的路径中，以便您可以运行命令行php -l filename.php以获得即时解析错误像上面那样的消息。

这里是你的代码与固定全解析错误：

<?php 
ini_set('display_errors', true); 
ini_set('log_errors', true); 
error_reporting(E_ALL); 
ini_set('error_log', 'php.log'); 
$field_fname = $_GET['fname'] ; 
$field_lname = $_GET['lname'] ; 
$field_bname = $_GET['bname'] ; 
$field_email = $_GET['email'] ; 
$field_address = $_GET['address'] ; 
$field_city = $_GET['city'] ; 
$field_state = $_GET['state'] ; 
$field_zip = $_GET['zip'] ; 
$field_country = $_GET['country'] ; 
$field_comments = $_GET['comments'] ; 

$mail_to = '[email protected]'; 
$subject = 'Message from a site visitor '.$field_fname .$field_lname; 

$body_message = 'From: '.$field_fname .$field_lname .'at' .$field_bname ."\n"; 
$body_message = 'E-mail: '.$field_email ."\n"; 
$body_message = 'Address:'.$field_address ."\n"; 
$body_message = 'City:'.$field_city ."\n"; 
$body_message = 'State:'.$field_state ."\n"; 
$body_message = 'Zip Code:'.$field_zip ."\n"; 
$body_message = 'Country:'.$field_country ."\n"; 
$body_message = 'Message: '.$field_comments; 

$headers = 'From: '.$field_email."\r\n"; 
$headers .= 'Reply-To: '.$field_email."\r\n"; 

$mail_status = mail($mail_to, $subject, $body_message, $headers); 

if ($mail_status) { ?> 
    <script language="javascript" type="text/javascript"> 
     alert('Thank you for the message. We will contact you shortly.'); 
     window.location = 'index.html'; 
    </script> 
<?php 
} 
else { ?> 
    <script language="javascript" type="text/javascript"> 
     alert('Message failed. Please, send an email to [email protected]'); 
     window.location = 'index.html'; 
    </script> 
<?php 
} 
?>

您很可能在默认情况下关闭显示错误的服务器上。你应该能够让他们在脚本（假设你不能访问服务器的conf或只希望它为一个脚本）在你的PHP的顶部，这样的：

ini_set("display_errors", "on"); 

那么就应该输出你的错误。

你在日志中没有得到任何东西的原因是因为设置错误日志和日志文件的php文件包含语法错误，因此无法解析，所以错误日志选项从不设置。为了避免这种情况，我建议把它放在php.ini文件或者.htaccess文件中，如果可能的话。你可以看到这是如何完成的：http://perishablepress.com/advanced-php-error-handling-via-htaccess/
