hi
tell me how to create a condition to display the category where more >1 ad, which is < than 1, do not display them

<div id="search-cat" class="search-cat">
            <div class="cat-tab">
              <?php $cat_id = osc_category_id(); ?>

              <?php if(!empty($subcats)) { ?>
                <?php foreach($subcats as $s) { ?>
                  <?php $search_params['sCategory'] = $s['pk_i_id']; ?>

                  <div class="link-wrap">
                    <a href="<?php echo osc_search_url($search_params); ?>" <?php echo ($s['pk_i_id'] == $search_cat_id ? 'class="bold"' : ''); ?>>
                      <?php echo $s['s_name'] . ' <strong>' . $s['i_num_items'] . '</strong>'; ?>
                    </a>
                  </div>

You may try to use function:
osc_category_total_items()
It returns number of listings in category.

I mean if for example in the category bmw has 1 ad category to display.If the category audi 0 ads category does not show
Do not need to show a category in which no ads, and if there is 1 more category to display

@san37
I got you all required.
if(osc_category_total_items() > ) { .... some code ... }

  <?php if(osc_category_total_items()>1){ echo '('. $s['s_name']. $s['i_num_items'].')';} ?>
Tried so, but remained still, where less than 1 are displayed
What's wrong?

First try if item counts are correct. And you should know what are you doing, I gave you all the tools required.
