我正在尝试将值插入 mysql 数据库,但出现“内部服务器错误”并且不知道为什么。我使用上传表单获取用户数据,然后使用上传处理器文件将数据写入服务器。该表格基于在线工作教程,因此一切正常,但每当我添加 SQL 代码时,它就会停止工作。我的代码在下面,非常感谢您花时间查看它。

<?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".
'"http://www.w3.org/TR/html4/strict.dtd">'."nn".
'<html lang="en">'."n".
' <head>'."n".
' <meta http-equiv="content-type" content="text/html; charset=iso-8859-1">'."nn".
' <link rel="stylesheet" type="text/css" href="stylesheet.css">'."nn".
' <title>Upload error</title>'."nn".
' </head>'."nn".
' <body>'."nn".
' <div id="Upload">'."nn".
' <h1>Upload failure</h1>'."nn".
' <p>An error has occurred: '."nn".
' <span class="red">' . $error . '...</span>'."nn".
' The upload form is reloading</p>'."nn".
' </div>'."nn".
'</html>';
exit;
} // end error handler

?>

最佳答案

您的第 95 行中有此代码:

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

应该是

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