在4列自定义菜单中显示WooCommerce产品类别

Question

我试图在下拉菜单中列出一组产品类别(x)，但是如果产品类别的总量大于x，则只列出x减去1并显示“查看所有类别”链接。我试图实现的是，每列只有8个条目(包括查看所有链接)，共有4列。

我是一个初学者，我已经用尽了我的知识，如果/其他逻辑。我所做的一切都把结果搞砸了。

下面是在8列中列出它们的基本代码，总共为32列。Id喜欢，如果有33个或更多的类别，为32是一个链接到所有他们。如果只有32，那么只需列出所有32没有链接。

 'product_cat',
     'orderby'      => 'name',
     'number'       => 32,   //maximum to list
     'title_li'     => '',
     'show_count'   => 0,    // 1 for yes, 0 for no
     'pad_counts'   => 0,    // 1 for yes, 0 for no
     'hierarchical' => 1,    // 1 for yes, 0 for no
     'hide_empty'   => 0,    // 1 for yes, 0 for no
     'echo'  => 0,           // 1 for yes, 0 for no
     'exclude' => '73, 74, 16', //best sellers, new, and uncategorized
     'depth'  => '1',        //top level categories, not sub
     'style'  => '',         //default is list with bullets, '' is without
);

// Grab top level categories
$get_cats = wp_list_categories($args);

// Split into array items
$cat_array = explode("
",$get_cats);

// Amount of categories (count of items in array)
$results_total = count($cat_array);

// How many tags to show per list-8)
$remainder = ($results_total-8);
$cats_per_list = ($results_total-$remainder);

// Counter number for tagging onto each list
$list_number = 1;

// Set the category result counter to zero
$result_number = 0;
?>



= $cats_per_list) { 
        $result_number = 0; 
        $list_number++;
        echo ''.$category.'  ';
    }
    else {         
        echo ''.$category.''; 
    }
}
echo 'View Categories';
?>

以下将显示在4列，32术语，最多在所有(产品类别)，所以8个项目的一栏。如果有超过32个术语，则将第32项替换为“查看类别”自定义链接项：

 $taxonomy,
    'number'       => ( $max_items + 1 ), // 33 max
    'title_li'     => '',  // disabled
    'pad_counts'   => 0,   // no
    'hide_empty'   => 0,   // no
    'echo'         => 0,   // return (not echo)
    'style'        => '',  // Without style (bullets)
    'depth'        => '1', // Top level terms only
    'exclude'      => $excluded_ids,
) );

$terms_array = explode( "
", $terms_list ); // Split each item in an array of terms

array_pop($terms_array); // <== We remove last empty item from the array.

$items_count = count($terms_array); // get items (terms) count

// Loop through product categories terms
foreach ( $terms_array as $term_html ) {
    if ( $counter == 0 ) { // column start
        $html .= '';
    }

    if( $items_count > $max_items && $col_count == $number_of_cols && $counter == ($items_per_col - 1) ) {
        $link    = home_url( "/all-categories/", "https" );
        $html .= '' . __("View Categories") . '';
    }
    else {
        $html .= '' . $term_html . '';
    }

    $counter++; // Increase items counter

    if ( $counter == $items_per_col ) { // column end
        $html .= '';

        $counter = 0; // Reset items counter
        $col_count++; // Increase colum count

        if ( $col_count > $number_of_cols ) {
            break; // Stop the loop (to be sure)
        }
    }
}

## html output
echo '' . $html. ''; 
?>

测试和工作。
