Title: [Mod] Previous < > Next Category (zapp through the categories)
Post by: Rembrandt on August 23, 2012, 06:42:35 PM

Hi!

It works the same as on the details pages, just with the categories.

1.) search in categories.php:

//-----------------------------------------------------
//--- Show Categories ---------------------------------

insert above:

//################### START [Mod]Previous < > Next Category ##################################
if (check_permission("auth_viewcat", $cat_id)) {
  $zapp_cache = array();
  if (in_array($cat_id, $cat_parent_cache[0])){
    foreach ($cat_parent_cache[0] as $val) {
      if(check_permission("auth_viewcat", $val)) {
        $zapp_cache[] = $val;
      }
    }
  }
  else{
    foreach ($cat_parent_cache[$cat_cache[$cat_id]['cat_parent_id']] as $val) {
      if (check_permission("auth_viewcat", $val)) {
        $zapp_cache[] = $val;
      }
    }
  }
  
  $act_key = array_search($cat_id, $zapp_cache);
  $last_key  = count($zapp_cache) - 1;
  $next_cat_id = (isset($zapp_cache[$act_key + 1])) ? $zapp_cache[$act_key + 1] : $zapp_cache[0];
  $prev_cat_id = (isset($zapp_cache[$act_key - 1])) ? $zapp_cache[$act_key - 1] : $zapp_cache[$last_key];
  unset($zapp_cache);
}

if (!empty($cat_cache[$next_cat_id])) {
  $next_cat_name = format_text($cat_cache[$next_cat_id]['cat_name'], 2);
  $next_cat_url = $site_sess->url(ROOT_PATH."categories.php?".URL_CAT_ID."=".$next_cat_id);
}

if (!empty($cat_cache[$prev_cat_id])) {
  $prev_cat_name = format_text($cat_cache[$prev_cat_id]['cat_name'], 2);
  $prev_cat_url = $site_sess->url(ROOT_PATH."categories.php?".URL_CAT_ID."=".$prev_cat_id);
}
//################### End [Mod]Previous < > Next Category ##################################

search:

$site_template->register_vars(array(
  "categories" => get_categories($cat_id),

insert below:

//######### START [Mod]Previous < > Next Category #########
  "next_cat_id" => $next_cat_id,
  "next_cat_name" => $next_cat_name,
  "next_cat_url" => $next_cat_url,
  "prev_cat_id" => $prev_cat_id,
  "prev_cat_name" => $prev_cat_name,
  "prev_cat_url" => $prev_cat_url,
  "lang_prev_cat" => $lang['prev_cat'],
  "lang_next_cat" => $lang['next_cat'],
//######## End [Mod]Previous < > Next Category ############


2.) search in your lang/main.php "?>" and insert above:
(deutsch)

//########## START [Mod]Previous < > Next Category #########
$lang['prev_cat'] = "Vorherige Kategorie:";
$lang['next_cat'] = "Nächste Kategorie:";
//########## End [Mod]Previous < > Next Category ###########

(english)

//########## START [Mod]Previous < > Next Category #########
$lang['prev_cat'] = "Previous Category:";
$lang['next_cat'] = "Next Category:";
//########## End [Mod]Previous < > Next Category ###########


3.) search in your Templates/categories.html

Code: [Select]

<hr size="1">
and insert below (or where ever you want):

Code: [Select]

               <table width="100%" border="0" cellspacing="0" cellpadding="1">
                  <tr>
                    <td class="bordercolor">
                      <table width="100%" border="0" cellspacing="0" cellpadding="3">
                          <tr valign="top">
                            <td class="row2"> {if prev_cat_name}{lang_prev_cat}<br>&nbsp;&nbsp;
                              <b><a href="{prev_cat_url}">{prev_cat_name}</a></b>{endif prev_cat_name}&nbsp;
                            </td>
                            <td align="right" class="row2"> &nbsp;{if next_cat_name}{lang_next_cat}<br>
                              <b><a href="{next_cat_url}">{next_cat_name}</a>&nbsp;&nbsp;&nbsp;</b>{endif next_cat_name}
                            </td>
                          </tr>
                        </table>
                      </td>
                    </tr>
                  </table>
                  <br>
