Hi as the subject says I am trying to upload an image to the server and at the same time add the url to the database. I have achieved both seperately but I am have difficulty combining them. Here is the code I am trying.

[color=green]<form enctype="multipart/form-data" action="uploader.php" method="POST">

<input type="hidden" name="MAX_FILE_SIZE" value="100000000000" />
Choose a file to upload: <input name="uploadedfile" type="file" /><br />
<input type="submit" value="Upload File" />

</form>[/color] This the form to browse for image and pass it to the uploaderphp file which uploads the file to the server.

This is where I am struggling. I have the results from the upload form passed to the uploader.php page and I am trying to pass it onto the uploaderupdate.php but I am having no success in passing the variable stored as file.

Here are the uploader.php

[color=red]<form name="load" action="uploaderupdate.php" method="post">
<?php

// Where the file is going to be placed
$target_path = "C:\kev\ ";

/* Add the original filename to our target path.  */
$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);

if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path))
{
    echo "The file ".  basename( $_FILES['uploadedfile']['name']).  " has been uploaded to folder $target_path";
}
   
else
{
    echo "There was an error uploading the file, please try again!";
}
$file = $target_path;
echo $file;

$file = 'file';
echo $file;
  ?>
  <tr>
<td><input type='hidden' name='file' /></td>

<td valign = "top"><input type="submit" name="submit" value="Add new photo"></td>
</tr>
      <?php
?>
</form>[/color]

and uploaderupdate.php files.

[color=navy]<?php
 
$user  = $_POST['file'];
$user  = strtoupper($user);

      echo $user;
     
?>[/color]

this is a cool class to do what you want... usage is at the bottom, and you can either upload with no validation, or with. pretty easy to get your head around, just copy all this into a file, call it something like class.fileupload.php, and include that in your page. then use the usage instructions at the bottom, wherever you want to use it.

[code]<?php
  class Upload_Files {
