Hi guys im doing a custom shortcode where the client can set a custom taxonomy and display in my sidebar

I want to use a template using the get_template_part but i dont get the terms of the taxonomy

I'm using the following code to display the shortcode

function cat_widgets( $atts ) {
    return ob_get_clean();
add_shortcode( 'cat_widgets', 'cat_widgets' );

add_filter( 'widget_text', 'do_shortcode' );

And in the show-taxonomy.php my code is

    $atts = shortcode_atts( array(
        'custom_taxonomy' => '',
    ), $atts, 'atributes' );
    $terms_categorias = get_terms([
        'taxonomy' => $atts['custom_taxonomy'],
        'hide_empty' => false,
        'orderby' => 'term_id',
        'order' => 'ASC' 
    <ul class="product-categories">
        <?php foreach($terms_categorias as $term): ?>
            <li class="cat-item">
                <a href="<?php echo esc_url( get_term_link($term) ); ?>">
                    <?php echo esc_html($term->name); ?>
        <?php endforeach; ?>

I also tried to put the atts and get the terms in the shortcode after de ob_start(); but the returns is the same

Is there something that im missing?

The $atts in your template part (templates/show-taxonomy.php) that you passed to shortcode_atts() is not defined, so you need to define it by passing it via the third parameter for get_template_part() like this:

get_template_part( 'templates/show-taxonomy', '', array( 'atts' => $atts ) );

Then in the template part, use $args['atts'] to access the shortcode parameters:

$atts = shortcode_atts( array(
    'custom_taxonomy' => '',
), $args['atts'], 'atributes' ); // here, use $args['atts'] and not $atts

And actually, in the above shortcode_atts() call, the third parameter should be cat_widgets (i.e. the 1st parameter for add_shortcode()) and not atributes. :)

  • Glad it helped! :-) (PS: I revised my answer a bit - mainly to reword the first paragraph).
