I have a table with 4 fields Id - Auto Increment, Date, Category, photo (for this field it just contains the photo name)

I need to remove previously uploaded photo from server
upload a new photo
update the table to reflect the change

I can delete the file with unlink but then how do I pass the record info to the next part where I can upload a new file and update the record with the new info.
I have a working script to upload a new photo and update the record but the old file remains on the server
Code:
  
<?php
/* 
 EDIT.PHP
 Allows user to edit specific entry in database
*/
 include('inc_header.php');

 // creates the edit record form
 // since this form is used multiple times in this file, I have made it a function that is easily reusable
     function renderForm($Id, $Date, $Catagory, $photo, $error)
      {
 ?>
  <?php 
 // if there are any errors, display them
     if ($error != '')
       {
     echo '<div style="padding:4px; border:1px solid red; color:red;">'.$error.'</div>';
 }
 ?> 
     <form method="post" action="upload2.php" enctype="multipart/form-data">
     <table width="600" cellpadding="5" cellspacing="1" border="1">
     <input type="hidden" name="Id" value="<?php echo $Id; ?>"/>
     <tr>
     <td bgcolor="#e9e9e9" align="right">Record ID:</td>
     <td bgcolor="ffffff" align="left"><?php echo $Id; ?></td>
     </tr>
     <tr>
     <input type="hidden" name="Date" value="<?php echo $Date; ?>"/>
     <td bgcolor="#e9e9e9" align="right">Date:</td>
     <td bgcolor="#ffffff" align="left"><?php echo $Date; ?></td>
     </tr>
     <tr>
     <input type="hidden" name="Catagory" value="<?php echo $Catagory; ?>"/>
     <td bgcolor="#e9e9e9" align="right">Catagory:</td>
     <td bgcolor="#ffffff" align="left"><?php echo $Catagory; ?></td>
     </tr>
     <tr>Current Photo - <?php echo $photo; ?>
     <td bgcolor="#e9e9e9" align="right">Photo</td>
     <td bgcolor="#ffffff" align="left"> <input type="file" name="photo" id="photo"></td>
     </tr>
     <tr>
     <td bgcolor="#e9e9e9" align="right">&nbsp;</td>
     <td bgcolor="#ffffff" align="center"><input type="submit" name="submit" value="Submit"><input type="reset" name="Reset" value="Clear Form"><input type=button value="Cancel" onClick="history.go(-1)"><br>&nbsp;</td>
     </tr>
     </table>
     </form> 
 </body>
 </html> 
 <?php
 }
 // connect to the database
     include('dbcon.php');
 
 // check if the form has been submitted. If it has, process the form and save it to the database
     if (isset($_POST['submit']))

       { 
 // confirm that the 'id' value is a valid integer before getting the form data
     if (is_numeric($_POST['Id']))
      {

 // get form data, making sure it is valid
      $Id = $_POST['Id'];
      $Date = $_POST['Date'];
      $Catagory = $_POST['Catagory']; 
      $photo=($_FILES['photo']['name']);

// check that fields you want required are filled in
     if ($Catagory == '')
      {
 // generate error message
      $error = 'ERROR: Please fill in all required fields!';
 
 //error, display form
      renderForm($Id, $Date, $Catagory, $photo, $error);
 }
   else
      {
 // save the data to the database
      mysql_query("UPDATE test SET  Date='$Date', Catagory='$Catagory', photo='$photo' WHERE Id='$Id'")
 or die(mysql_error()); 
     }
 }
 else
      {
 // if the 'id' isn't valid, display an error
      echo 'Error!';
    }
 }
      else
 // if the form hasn't been submitted, get the data from the db and display the form
      {
 
 // get the 'id' value from the URL (if it exists), making sure that it is valid (checking that it is numeric/larger than 0)
     if (isset($_GET['Id']) && is_numeric($_GET['Id']) && $_GET['Id'] > 0)
       {
 // query db
     $Id = $_GET['Id'];
     $result = mysql_query("SELECT * FROM test WHERE Id=$Id")
     or die(mysql_error()); 
     $row = mysql_fetch_array($result);
 
 // check that the 'id' matches up with a row in the database
       if($row)
        {
 
 // get data from db
     $Id = $row['Id'];
     $Date = $row['Date'];
     $Catagory = $row['Catagory'];
     $photo = $row['photo'];

 // show form
       renderForm($Id, $Date, $Catagory, $photo, $error);
        }
      else
 // if no match, display result
      {
      echo "No results!";
      }
 }
       else
 // if the 'id' in the URL isn't valid, or if there is no 'id' value, display an error
        {
       echo 'Error!';
      }
 }
?>
And the upload file
Code:
<?php

///DEBUGGING
if (!empty($_POST)) {
   print "<pre>This is your \$_POST array \n\n".print_r($_POST,true)."</pre>"; 
}

//This gets all the other information from the form
   $id        = isset($_POST['Id'])        ? $_POST['Id']        : 'NULL'; 
   $date      = isset($_POST['Date'])      ? $_POST['Date']      : ''; 
   $catagory      = isset($_POST['Catagory'])      ? $_POST['Catagory']      : ''; 
   $photo=($_FILES['photo']['name']);  


// Connects to your Database
 require('dbcadmin.php');
/////////////////////


/////////////////////

$folder = $_POST['Catagory'];  
  include('class.upload.php');
//Check that we have a file

   // we instanciate the class for each element of $file
         $handle = new Upload($_FILES['photo']);

        // then we check if the file has been uploaded properly
        // in its *temporary* location in the server (often, it is /tmp)
        if ($handle->uploaded) {
       $handle->auto_create_dir = false;
       $handle->image_resize         = true;
       $handle->image_x              = 600;
       $handle->image_ratio_y        = true;

            // now, we start the upload 'process'. That is, to copy the uploaded file
            // from its temporary location to the wanted location
            // It could be something like $handle->Process('/home/www/my_uploads/');
        $handle->process('/home/xxxxxxxxx/public_html/test/images/'.$folder);

            // we check if everything went OK
              if ($handle->processed) {
           echo '<center><p>Image resized and uploaded to ' .$folder;
                // everything was fine !
             echo ' &nbsp; <a href="recipesview-pages.php">Go Back</a></p>';
            } else {
                // one error occured
                echo '<p class="result">';
                echo '  <b>File not uploaded to the wanted location</b><br />';
                echo '  Error: ' . $handle->error . '';
                echo '</p>';
            }


        } else {
            // if we're here, the upload file failed for some reasons
            // i.e. the server didn't receive the file
            echo '<center><p class="result">';
            echo '  <b>No file chosen for upload</b><br />';
            echo ' ' . $handle->error . '';
            echo '</p>';
        }
  

?>
As I said those 2 files work awesome, I just have no idea where to put the unlink info. Thanks in advance. I apologize if I posted to much info.
