Hide specific category in listings - wordpress

Question

I'm working on a Wordpress theme. The theme is Classifieds theme from premiumpress. The theme has a shortcode to list all the listings. The corresponding shortcode is [LISTINGS].
The function for the shortcode is as follows
/* =============================================================================
[LISTINGS] - SHORTCODE
========================================================================== */
function wlt_page_listings( $atts, $content = null ) {
global $userdata, $wpdb, $CORE; $STRING = ""; $extra=""; $i=1; $stopcount = 4;
extract( shortcode_atts( array( 'query' => '', 'show' => '', 'type' => '', 'cat' => '', 'orderby' => '', 'order' => '', 'grid' => "no", 'featuredonly' => "no"), $atts ) );
// SETUP DEFAULTS
if(!isset($atts['show']) || (isset($atts['show']) && $atts['show'] == "") ){ $atts['show'] = 5; }
if($atts['type'] == ""){ $atts['type'] = THEME_TAXONOMY.'_type'; }
if($atts['orderby'] == ""){ $atts['orderby'] = "post_title"; }
if($atts['order'] == ""){ $atts['order'] = "desc"; }
// DEFAULT FOR LIST STYLE
if($grid == "yes"){
$sstyle = "grid_style";
$STRING .= '<script language="javascript">jQuery(window).load(function() { equalheight(\'.grid_style .item .thumbnail\');});</script>';
}else{
$sstyle = "list_style";
}
$query= str_replace("#038;","&",$query);
if(strlen($query) > 1){
// ADD ON POST TYPE FOR THOSE WHO FORGET
if(strpos($query,'post_type') == false){
$args = $query ."&post_type=".THEME_TAXONOMY."_type";
}else{
$args = $query;
}
}elseif($featuredonly == "yes"){
$args = array('posts_per_page' => $atts['show'],
'post_type' => $atts['type'], 'orderby' => $atts['orderby'], 'order' => $atts['order'],
'meta_query' => array (
array (
'key' => 'featured',
'value' => 'yes',
)
)
);
}else{
/*** default string ***/
$args = array('posts_per_page' => $atts['show'], 'post_type' => $atts['type'], 'orderby' => $atts['orderby'], 'order' => $atts['order'] );
}
/*** custom category ***/
if(strlen($atts['cat']) > 1){
$args = array('tax_query' => array( array( 'taxonomy' => str_replace("_type","",$atts['type']) ,'field' => 'term_id','terms' => array( $atts['cat'] ))), 'posts_per_page' => $atts['show'] );
}
// BUILD QUERY
$the_query = new WP_Query( hook_custom_queries($args) );
if ( $the_query->have_posts() ) {
$STRING .= '<div class="_searchresultsdata"><div class="wlt_search_results row '.$sstyle.'">';
while ( $the_query->have_posts() ) { $the_query->the_post(); $post = get_post();
$STRING .= '<div class="item '.hook_gallerypage_item_class('col-md-4').$CORE->FEATURED($post->ID).'">'.hook_item_cleanup(hook_gallerypage_item($CORE->ITEM_CONTENT($post))).'</div>';
}
$STRING .= '</div></div><div class="clearfix"></div>';
}
// END QUERY
wp_reset_postdata();
return $STRING;
}
add_shortcode( 'LISTINGS', array($this,'wlt_page_listings') );
The shortcode does not have an attribute to hide certain categories. I need to display all listings, except the ones in wedding category, which is a custom taxonomy. Is there any way to do that with the above code?
Will something like this work?
if ( is_tax( 'listing', 'wedding' ) ) {
do not display the wedding listings and display the rest}
Any suggestions?
EDITS:
This my online site url : http://webzer.comxa.com/
The main page shows the all the products.I like to have all but not one that is from wedding category coz i have separate page to list wedding category.
i have tried this where 51 is the page id of my home store page
if ( is_page( 51 ) && is_tax( 'listing', 'wedding' ) ) {
?><style>.caption {display:none!important;}</style>
<?php } ?>
this also didn't work

Consider this :
change
function wlt_page_listings( $atts, $content = null ) {
to
function wlt_page_listings( $atts, $content = null, $exclude=array(99) ) { // 99 is wedding cat id
where $exclude is an optional array of excluded cat names (99 in there for ease of testing/use)
Then in the
while ( $the_query->have_posts() ) {
add something like this:
$post = get_post(); // get post obj, will use the ID attr
$cats = wp_get_post_categories( $post->ID )); // returns array of IDs for all cats
foreach($exclude as $x){ // loop on the excluded cat ids
if(in_array($x, $cats))continue; // if excluded skip
}

I think this will work or at least got you close.
display:none is bad mojo as the content will still be in your source code for others to see.
I hope I addressed the problem correctly for you, cheers.
