Question

我正在尝试将值插入到mysql数据库中，并且我得到了一个＆＃34;内部服务器错误＆＃34;而且不知道为什么。我使用上传表单来获取用户数据，然后使用上传处理器文件将数据写入服务器。该表单基于在线工作教程，所以一切正常，但每当我添加SQL代码时，它就停止工作了。我的代码如下，感谢您抽出时间。

<?php 

// Upload form based off of http://www.htmlgoodies.com/beyond/php/article.php/3877766

// make a note of the current working directory, relative to root. 
$directory_self = str_replace(basename($_SERVER['PHP_SELF']), '', $_SERVER['PHP_SELF']); 

// make a note of the directory that will recieve the uploaded file 
$uploadsDirectory = $_SERVER['DOCUMENT_ROOT'] . $directory_self . 'uploaded_files/'; 

// make a note of the location of the upload form in case we need it 
$uploadForm = 'http://' . $_SERVER['HTTP_HOST'] . $directory_self . 'upload.form.php'; 

// make a note of the location of the success page 
$uploadSuccess = 'http://' . $_SERVER['HTTP_HOST'] . $directory_self . 'upload.success.php'; 

// fieldname used within the file <input> of the HTML form 
$fieldname = 'file'; 

$promoName = 'sale_name';
$expirDate = 'sale_expir';

// Now let's deal with the upload 

// possible PHP upload errors 
$errors = array(1 => 'php.ini max file size exceeded', 
                2 => 'html form max file size exceeded', 
                3 => 'file upload was only partial', 
                4 => 'no file was attached'); 

// check the upload form was actually submitted else print the form 
isset($_POST['submit']) 
    or error('the upload form is needed', $uploadForm); 

// check for PHP's built-in uploading errors 
($_FILES[$fieldname]['error'] == 0) 
    or error($errors[$_FILES[$fieldname]['error']], $uploadForm); 

// check that the file we are working on really was the subject of an HTTP upload 
@is_uploaded_file($_FILES[$fieldname]['tmp_name']) 
    or error('not an HTTP upload', $uploadForm); 

// validation... since this is an image upload script we should run a check   
// to make sure the uploaded file is in fact an image. Here is a simple check: 
// getimagesize() returns false if the file tested is not an image. 
@getimagesize($_FILES[$fieldname]['tmp_name']) 
    or error('only image uploads are allowed', $uploadForm); 

// make a unique filename for the uploaded file and check it is not already 
// taken... if it is already taken keep trying until we find a vacant one 
// sample filename: 1140732936-filename.jpg 
$now = time(); 
while(file_exists($uploadFilename = $uploadsDirectory.$now.'-'.$_FILES[$fieldname]['name'])) 
{ 
    $now++; 
} 

// now let's move the file to its final location and allocate the new filename to it 
@move_uploaded_file($_FILES[$fieldname]['tmp_name'], $uploadFilename) 
    or error('receiving directory insuffiecient permission', $uploadForm); 

// these commands move the information onto the database
$imageURL = $uploadsDirectory.$uploadFilename;

$host = '***removed***';
$dbName = '***removed***';
$dbUser = '***removed***';
$dbPass = '***removed***';

$conn = mysql_connect($host, $dbUser, $dbPass);

if (!$conn){
    die('Could not connect: '.mysql_error());
} else {
    echo 'Connected successfully!';
}

$sql = "INSERT INTO '$dbName'.sales (name, date, saleImage) VALUES ('$promoName', '$expirDate', '$imageURL');";

mysql_select_db($dbName, $conn);

mysql_query($sql, $conn);

mysql_close($conn);
// database work is done

// If you got this far, everything has worked and the file has been successfully saved. 
// We are now going to redirect the client to a success page. 
header('Location: ' . $uploadSuccess); 

// The following function is an error handler which is used 
// to output an HTML error page if the file upload fails 
function error($error, $location, $seconds = 5) 
{ 
    header("Refresh: $seconds; URL="$location""); 
    echo '<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"'."n".

Answer 1

你的第95行有这段代码：

header("Refresh: $seconds; URL="$location"");

哪个应该是

header("Refresh: $seconds; URL=\"$location\"");

SQL代码的内部服务器错误
