[Tutorial] Add option to disable download category

Recommended Posts

Hello folks! I thought about to edit categories in the default download module and changed it to my needs. After you deactivate a download category, it wont show up in your list.

Important information: BEFORE do this tutorial, backup the database tables and files you'll edit.

  • lib/skins/pandaair_theme/downloads_list.php
  • admin/modules/Downloads/Downloads.php
  • admin/templates/downloads_categoryform.php
  • core/common/DownloadData.class.php
  • database table phpvms_downloads

1. Open your database and run the following command. It will add a column to your downloads table. Be sure to add the right prefix for the table:

ALTER TABLE `phpvms_downloads` ADD `active` INT NOT NULL DEFAULT '1' AFTER `hits`;

 

2. Replace the content of the file "admin/templates/downloads_categoryform.php" with following:

<?php if(!defined('IN_PHPVMS') && IN_PHPVMS !== true) { die(); } ?>
<h3><?php echo $title?></h3>
<form id="form" method="post" action="<?php echo adminaction('/downloads/overview'); ?>">
<dl>
	<dt>Category Name</dt>
	<dd><input name="name" type="text" value="<?php echo $category->name; ?>" /></dd>
    <dt>Category Active? <input name="active" type="checkbox" <?= ($category->active) ? "checked":"" ?> <?= (empty($category->name)) ? "checked":"" ?> style="margin-bottom: 20px;" /></dt>
	<dt></dt>
	<dd><input type="hidden" name="id" value="<?php echo $category->id;?>" />
		<input type="hidden" name="action" value="<?php echo $action;?>" />
		<input type="submit" name="submit" value="<?php echo $title;?>" />
	</dd>
</dl>
</form>

We added the checkbox to enable/disable the category.

 

3. Edit the file "core/common/DownloadData.class.php"

The following two functions have to be replaced: "AddCategory" and "EditAsset":

public static function AddCategory($name, $link = '', $image = '', $active = 1) {
    if ($name == '') return false;

    $sql = "INSERT INTO " . TABLE_PREFIX . "downloads
   (pid, name, link, image)
VALUES (0, '$name', '$link', '$image', '$active')";

    $res = DB::query($sql);
    if (DB::errno() != 0) return false;

    return true;
}
public static function EditAsset($data) {
    /*$data = array(
    'id' => ''
    'parent_id' => '',
    'name' => '',
    'description' => '',
    'link' => '',
    'image' => '',
    );
    */
    if ($data['id'] == '' || $data['name'] == '') return false;

    $data['id'] = intval($data['id']);
    $data['name'] = DB::escape($data['name']);
    $data['parent_id'] = intval($data['parent_id']);

    $sql = "UPDATE " . TABLE_PREFIX . "downloads
   SET `pid`={$data['parent_id']}, `name`='{$data['name']}', `active`='{$data['active']}', 
      `description`='{$data['description']}', link='{$data['link']}', image='{$data['image']}'
   WHERE id={$data['id']}";

    $res = DB::query($sql);

    if (DB::errno() != 0) return false;

    return true;
}

Well, we included there the "active" parameter from the checkbox, so it will be changed in the database.

 

4. The file "admin/modules/Downloads/Downloads.php" contains two functions "AddCategoryPost" and "EditCategoryPost". We have to replace them with the following:

protected function AddCategoryPost() {
       $this->checkPermission(EDIT_DOWNLOADS);

   if ($this->post->name == '') {
      $this->set('message', 'No category name entered!');
      $this->render('core_error.php');
      return;
   }

   if (DownloadData::FindCategory($this->post->name)) {
      $this->set('message', 'Category already exists');
      $this->render('core_error.php');
      return;
   }

       if(!empty($this->post->active)){
           $active = 1;
       } else {
           $active = 0;
       }

   DownloadData::AddCategory($this->post->name, '', '', $active);

   $this->set('message', 'Category added!');
   $this->render('core_success.php');
}
protected function EditCategoryPost() {
       $this->checkPermission(EDIT_DOWNLOADS);
   if ($this->post->name == '') {
      $this->set('message', 'No category name entered!');
      $this->render('core_error.php');
      return;
   }

       if(!empty($this->post->active)){
           $active = 1;
       } else {
           $active = 0;
       }

   $data = array('id' => $this->post->id, 'name' => $this->post->name, 'parent_id' => '', 'description' => '', 'link' => '', 'image' => '', 'active' => $active);

   DownloadData::EditAsset($data);

   $this->set('message', 'Category edited!');
   $this->render('core_success.php');

}

That's it for the "tricky" part. Now let's hide the deactivated categories in the core/templates/downloads_list.php.

Just search for the "foreach" loop of the categories and check if the category has "1" in the active parameter. If it doesn't, don't show the category:

foreach($allcategories as $category)
{
    if(!$category->active)
    {
        continue;
    }

// more stuff.....

 

Have fun and howdy!
