We could display images in gallery using shortcode just like this [gallery ids="130,126"]. I would like to achieve same thing but for categories. I have a shortcode that displays all terms of a custom post type called "theme_portfolio_image". What I want is that I would like to dislay only selected/specific categories.
<?php
function theme_shortcode_portfolio($atts , $content = '' ) {
// setup options
extract( shortcode_atts( array(
'title' => '',
'count' => 3,
'columns' => 3,
'cat' => '',
'style' => '',
'img_style' => '',
'portfolio' => ''
), $atts ) );
$query_options = array(
'post_type' => 'theme_portfolio_image',
'numberposts' => $count,
'orderby' => 'menu_order',
'order' => 'ASC'
);
$filters = get_terms( 'theme_portfolio_categories', array( 'hide_empty' => 1 ) );
if( !empty( $portfolio ) ) {
$portfolios = explode( ',', $portfolio );
$query_options['tax_query'][] = array(
'taxonomy' => 'theme_portfolio_categories',
'field' => 'slug',
'terms' => $portfolios
);
// remove portfolios from filters
foreach( $filters as $key => $filter ) {
// remove portfolio from filter if not needed
if( !in_array( $filter->slug, $portfolios ) ) {
unset( $filters[$key] );
}
}
}
$span = $columns == 3? 'span4':'span3';
$box_size = $columns == 3? 'box-huge':'box-big';
// fetch posts
$projects = get_posts( $query_options );
$projects_count = count( $projects );
$output = '';

$projects_per_row = ($span == 'span4')? 3:4;

Here is my shortcode
[portfolio columns="3" title="My Title"] but I would like to use it like this
[portfolio columns="3" title="My Title" ids="20,22,30,35"]
any help would be appreciated
