短代码-按字母顺序将属性的所有术语显示到有序列表中

这是您的全功能短代码。我用一组不同的术语对它进行了测试,它运行得很好(所以我希望你的测试是正确的,也能正常工作)。

在我迭代这个二维数组以生成您想要的显示之后

代码如下:

if (!function_exists('showbrands')) {
    
    function showbrands(){
    
        $term_arr = array();
    
        $terms = get_terms( array(
            'taxonomy' => 'pa_brand',
            'orderby' => 'name',
            'hide_empty' => false,
        ) );
    
        foreach ( $terms as $term ) {
            $brand = $term->name;
            $slug = $term->slug;
    
            // Getting the first letter of $brand term name
            $letter = substr($brand, 0, 1);
            
            // PREPARING DATA IN A BI DIMENSIONAL ARRAY
    
            // Inserting the $letter in an array just once (array level 1)
            // Inserting for each letter all the corresponding pairs "$brand => $slug" (array level 2)
            if(!array_key_exists($letter, $term_arr))
                $term_arr[$letter] = array($slug => $brand);
            else
                $term_arr[$letter][$slug] = $brand;
        }
    
        $output = '<div class="brandlist-container">';
    
        // ITERATING IN THE BI DIMENTIONAL $TERM_ARR ARRAY 
        
        // first level the letters
        foreach( $term_arr as $key_letter => $terms_in_letter ){
            $output .= '<span id="'. strtolower( $key_letter ) .'">'. $key_letter .'</span>
                  <ul class="brandlist">';
    
            // second level the $brand / $slug pairs
            foreach( $terms_in_letter as $key => $value ){
                $output .= '<li><a href="/brand/'.$key.'/">'.$value.'</a></li>';
            }
            $output .= '</ul>';
        }
        $output .= '</div>';
        
        return $output;
    }
    
    add_shortcode( 'showbrands', 'showbrands' );
    
}
