can you please guide me.. am not aware of file upload processes.. please share your suggestions

<html>
<head></head>
<body>
<form method="post" enctype="multipart/form-data">
<table width="350" border="0" cellpadding="1"
    cellspacing="1" class="box">
<tr>
  <td><h4>Please select a file</h4></td></tr>
<tr>
<td>
<input type="hidden" name="MAX_FILE_SIZE"
  value="16000000">
<input name="userfile" type="file" id="userfile"> 
</td>
<td width="80"><input name="upload"
  type="submit" class="box" id="upload" value=" Upload "></td>
 </tr>
</table>
</form>
  <a href="newsletter_sec.php">Back</a>
</body>
</html>
<?php
if(isset($_POST['upload'])&&$_FILES['userfile']['size']>0)
{
$fileName = $_FILES['userfile']['name'];
$tmpName  = $_FILES['userfile']['tmp_name'];
$fileSize = $_FILES['userfile']['size'];
//$fileType = $_FILES['userfile']['type'];
$fileType=(get_magic_quotes_gpc()==0 ? mysql_real_escape_string(
$_FILES['userfile']['type']) : mysql_real_escape_string(stripslashes ($_FILES['userfile']['name'])));
$fp      = fopen($tmpName, 'r');
$content = fread($fp, filesize($tmpName));
$content = addslashes($content);
fclose($fp);
if(!get_magic_quotes_gpc())
{
    $fileName = addslashes($fileName);
}
$con = mysql_connect('localhost', 'stthohuu_batch', 'abc') or die(mysql_error());
$db = mysql_select_db('stthohuu_church', $con);

/* identify the max id in existing data*/


$max_id[0]='';
$sql="SELECT id FROM newsletter WHERE id=(SELECT max(id) FROM newsletter)";
$result = mysql_query($sql);
$max_id = mysql_fetch_array($result);

if ($max_id[0]=='')
{
  $max_id[0]=0;
}
$id=0;
$id=$max_id[0]+1;  

/* to insert data into newsletter table */

if($db){
$query = "INSERT INTO newsletter (name, size, type, content ) ".
 "VALUES ('$fileName', '$fileSize', '$fileType', '$content')";
mysql_query($query) or die('Error, query failed'); 
mysql_close();
echo "<br>File $fileName uploaded<br>";
}else { echo "file upload failed"; }
} 
 ?>

This s working well in local xampp.. But NOT in web server.. :(

役に立ちましたか？

解決

The problem is with your MySQL Connection. Remove mysql_real_escape_string() before opening a MySQL Connection. Generally, your web server will have a different username and password from your local xampp account. Change them.

Also, a best practice is not to use mysql_* functions, instead replace them with mysqli_* or PDO.

他のヒント

You must use your server database setting. You can not use 'localhost' for server database. For more servers it is their database IP. For more detail you can contact your server administrator.
