Hi i have this image upload script, its giving me errors.
this script should get description of the image from user and upload image to database. please someone could take a look at my code. i really messed up the code. i am puzzled now.

<?php
if(isset($_POST['upload']) && $_FILES['userfile']['size'] > 0)
{


?>


 <form action="upload.php" method="post">
 Image Description: <input  type="text" name="imgdesc">
                               <input type="submit" value="submit">
</form>

<?php

$allowed_filetypes = array('.jpg','.jpeg','.png','.gif');
$max_filesize = 1445760;
$description = $_POST['imgdesc'];

$filename = $_FILES['userfile']['name'];
$ext = substr($filename, strpos($filename,'.'), strlen($filename)-1);

if(!in_array($ext,$allowed_filetypes))
  die('The file you attempted to upload is not allowed.');

if(filesize($_FILES['userfile']['tmp_name']) > $max_filesize)
  die('The file you attempted to upload is too large.');



} else {
     echo 'There was an error during the file upload.  Please try again.';
}




$fileName = $_FILES['userfile']['name'];
$tmpName  = $_FILES['userfile']['tmp_name'];
$fileSize = $_FILES['userfile']['size'];
$fileType = $_FILES['userfile']['type'];
$fp      = fopen($tmpName, 'r');
$content = fread($fp, filesize($tmpName));
$content = addslashes($content);
fclose($fp);
if(!get_magic_quotes_gpc())
{
    $fileName = addslashes($fileName);
}
include 'config.php';
include 'opendb.php';
$query = "INSERT INTO upload (name, size, type, content , description ) ".
"VALUES ('$fileName', '$fileSize', '$fileType', '$content', '$description')";
mysql_query($query) or die('Error, query failed');
include 'closedb.php';
echo "<br>File $fileName uploaded<br>";


?>
<form method="post" enctype="multipart/form-data">
    <table width="350" border="0" cellpadding="1" cellspacing="1" class="box">
        <tr>
            <td width="246">
                <input type="hidden" name="MAX_FILE_SIZE" value="2000000">
                <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>

What is the error? Can you post it?

Sory for late reply. Obviously $_FILES['userfile'] does not exist. You should place the code that reads the uploaded file information and writes to the database within the if(isset($_POST['upload']) && $_FILES['userfile']['size'] > 0) block. Something like this:

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'];
    $fp = fopen($tmpName, 'r');
    $content = fread($fp, filesize($tmpName));
    $content = addslashes($content);
    fclose($fp);
    if(!get_magic_quotes_gpc())
    {
        $fileName = addslashes($fileName);
    }
    include 'config.php';
    include 'opendb.php';
    $query = "INSERT INTO upload (name, size, type, content , description ) ".
    "VALUES ('$fileName', '$fileSize', '$fileType', '$content', '$description')";
    mysql_query($query) or die('Error, query failed');
    include 'closedb.php';
    echo "<br>File $fileName uploaded<br>";
?>


 <form action="upload.php" method="post">
 Image Description: <input  type="text" name="imgdesc">
                               <input type="submit" value="submit">
</form>

<?php

$allowed_filetypes = array('.jpg','.jpeg','.png','.gif');
$max_filesize = 1445760;
$description = $_POST['imgdesc'];

$filename = $_FILES['userfile']['name'];
$ext = substr($filename, strpos($filename,'.'), strlen($filename)-1);

if(!in_array($ext,$allowed_filetypes))
  die('The file you attempted to upload is not allowed.');

if(filesize($_FILES['userfile']['tmp_name']) > $max_filesize)
  die('The file you attempted to upload is too large.');



} else {
     echo 'There was an error during the file upload.  Please try again.';
}

This way the file gets inserted into the db only when some data about it exists. You might want to reaarange the code depending on what you actually want to achieve.
