Hide categories with no images

[shain]

Greetings everyone,

I have a quick question. If you have a look at: http://www.snaip.com/wildhorizons/categories.php?cat_id=97 , you will see that there are many categories with zero (0) images in them. Is there a way I can hide those categories? Then they will automatically appear when there's new images in them? I tried to look at functions.php in includes, but it is looking far way too complicated.

I like this request.

Make a backup of your includes/functions.php file. Then,

find :

    $site_template->register_vars(array(
      "cat_id" => $category_id,
      "cat_name" => $cat_cache[$category_id]['cat_name'],
      "cat_description" => $cat_cache[$category_id]['cat_description'],
      "cat_hits" => $cat_cache[$category_id]['cat_hits'],
      "cat_is_new" => $is_new,
      "lang_new" => $lang['new'],
      "sub_cats" => get_subcategories($category_id),
      "cat_url" => $site_sess->url(ROOT_PATH."categories.php?".URL_CAT_ID."=".$category_id),
      "random_cat_image_file" => $random_cat_image_file,
      "num_images" => $num_images
    ));
   
    $categories .= $site_template->parse_template("category_bit");
    $count++;
    $count2++;
    $categories .= "</td>\n</tr>\n";

replace with :

Code: [Select]


    if ($categories) {
 
    $site_template->register_vars(array(
      "cat_id" => $category_id,
      "cat_name" => $cat_cache[$category_id]['cat_name'],
      "cat_description" => $cat_cache[$category_id]['cat_description'],
      "cat_hits" => $cat_cache[$category_id]['cat_hits'],
      "cat_is_new" => $is_new,
      "lang_new" => $lang['new'],
      "sub_cats" => get_subcategories($category_id),
      "cat_url" => $site_sess->url(ROOT_PATH."categories.php?".URL_CAT_ID."=".$category_id),
      "random_cat_image_file" => $random_cat_image_file,
      "num_images" => $num_images
    ));
   
    $categories .= $site_template->parse_template("category_bit");
    $count++;
    $count2++;
    $categories .= "</td>\n</tr>\n";
   
    } ####### End of if statement.


I tried it with a single category (on both statement regarding ' existing & unexisting ' categories). Both matches perfectly. Hopefully, this is what you're looking for.

If not, you can always replace the backup file you made.

hhhmmm,

doesn´t work for subcats.....   

[TheOracle]

Sure,

replace this part :

if ($categories) {
 
    $site_template->register_vars(array(
      "cat_id" => $category_id,
      "cat_name" => $cat_cache[$category_id]['cat_name'],
      "cat_description" => $cat_cache[$category_id]['cat_description'],
      "cat_hits" => $cat_cache[$category_id]['cat_hits'],
      "cat_is_new" => $is_new,
      "lang_new" => $lang['new'],
      "sub_cats" => get_subcategories($category_id),
      "cat_url" => $site_sess->url(ROOT_PATH."categories.php?".URL_CAT_ID."=".$category_id),
      "random_cat_image_file" => $random_cat_image_file,
      "num_images" => $num_images
    ));
   
    $categories .= $site_template->parse_template("category_bit");
    $count++;
    $count2++;
    $categories .= "</td>\n</tr>\n";
   
    } ####### End of if statement.

with this one :

Code: [Select]

   
    if ($categories && function_exists('get_subcategories') && $num_images >= 1) {
 
    $site_template->register_vars(array(
      "cat_id" => $category_id,
      "cat_name" => $cat_cache[$category_id]['cat_name'],
      "cat_description" => $cat_cache[$category_id]['cat_description'],
      "cat_hits" => $cat_cache[$category_id]['cat_hits'],
      "cat_is_new" => $is_new,
      "lang_new" => $lang['new'],
      "sub_cats" => get_subcategories($category_id),
      "cat_url" => $site_sess->url(ROOT_PATH."categories.php?".URL_CAT_ID."=".$category_id),
      "random_cat_image_file" => $random_cat_image_file,
      "num_images" => $num_images
    ));
   
    $categories .= $site_template->parse_template("category_bit");
    $count++;
    $count2++;
    $categories .= "</td>\n</tr>\n";
   
    } ####### End of if statement.




Again - excellent idea. This even reduce my layout's height size for unused categories ' and ' subcategories usage so that, if they're empty, they won't show up.

TheOracle,

Thanks a lot for this one!

No problem. I liked this request very much.

[Gulper]

This is awesome!
Just one problem... empty categories are not visible anymore... but their space, where they have been, is still there... I mean, when I had a category overview with 9 categories and 5 of them were empty.... there are then 4 visible categories left... but the places, where the 5 empty categories were are still occupied.... so it looks very chaotic now...
Is there a way to reorder the category display, so that there are no empty spaces anymore?
..sorry for my bad english...

[TheOracle]

their space, where they have been, is still there...

Sounds like the table heading would need to be re-structured in two separated categories statement from the same action. The problem is, the $visible_cat_cache is being used from a single ' foreach ' statement in that function section. Let me play with it a little bit longer and I will post the results once I found the way to do this.

Sounds like fun.

The good news is, the first part is done.

[Gulper]

Would be more than great if you can solve this!
Thanx in advance.....

[TheOracle]

Update:

I have solved it but, the problem is, I'm encountering some difficulties to maintain the category layout from the functions. However, the good news is, I have successfully removed the empty URL titles entirely from the category box as requested above.

That said, the categories needs to be called from two seperated basis from the same general function. It is a little bit hard to code as, hopefully, the results will be posted soon.

Code: [Select]

Parse error: syntax error, unexpected ';', expecting T_PAAMAYIM_NEKUDOTAYIM or '(' in /home/myanimw/public_html/includes/template.php(101) : eval()'d code on line 7
