Unlink only if there is a new image to upload

[eluser]jzmwebdevelopement[/eluser]
Hey Darren,

I have tried what you have said and it seems that if I have more then one sale and update the image it seems to change all data in the other sales to the one that I have chosen to update and not upload the image.

Why?

View:

Code:

<?php if($sales_pages): ?>
        <?php foreach($sales_pages as $sale): ?>
     <div id ="sales">
        <span class"thumbnail"><a >id?&gt;"><img class="thumbnailImg">thumbname?&gt;" alt=""/></a>
        <span class="location">&lt;?= $sale->location?&gt;</span>
        <span class="price">&lt;?= $sale->price?&gt;</span>
        </span>
                </div>

        &lt;?php endforeach; ?&gt;
&lt;?php endif; ?&gt;

Controller

Code:

class Editsale extends CI_Controller {
    /**
     * This document sets the following for the editsale page
     *PHP Validation
     *Thumbnail and Image Sizes
     *Image Locations
     *DB Settings
     * @author Jess McKenzie
     */

    function __construct() {
    parent::__construct();

    }

    function index() {
       if(!$this->session->userdata('logged_in'))redirect('admin/home');
    
    $id = $this->uri->segment(4);
    # Set Main Page Data
        $data['title'] = 'Edit Sale:';
        $data['sales_pages'] = $this->sales_model->getSalesPages();
        $data['cms_pages'] = $this->navigation_model->getCMSPages();
        $data['sale']= $this->sales_model->getSalesContent($id);
