按字母对分类术语进行分组和排序-有更好的方法吗？

时间：2016-09-29 作者：Mike

背景：我在一个游戏博客上工作，我为游戏创建了一个自定义分类法。

我添加了一个游戏列表页面，它将（毫不奇怪地）列出所有non-empty 该分类法中的术语。知道这个列表将来可能会变得相当大，我想通过页面顶部的快速访问栏和每个部分末尾的“返回顶部”链接，按照术语的第一个字符对其进行排序和分组。

我想出了以下函数来检索排序列表，它工作得很好，但我想知道是否有更有效的方法来实现这一点（比如我还没有发现的一些核心选项）。

function bmg_getGameList() {
    $games = get_terms(BMG_GAME_SLUG, true);

    if ($games && !is_wp_error($games)) {
        $gameList = array(
            "#" =>  array(),    "A" =>  array(),    "B" =>  array(),
            "C" =>  array(),    "D" =>  array(),    "E" =>  array(),
            "F" =>  array(),    "G" =>  array(),    "H" =>  array(),
            "I" =>  array(),    "J" =>  array(),    "K" =>  array(),
            "L" =>  array(),    "M" =>  array(),    "N" =>  array(),
            "O" =>  array(),    "P" =>  array(),    "Q" =>  array(),
            "R" =>  array(),    "S" =>  array(),    "T" =>  array(),
            "U" =>  array(),    "V" =>  array(),    "W" =>  array(),
            "X" =>  array(),    "Y" =>  array(),    "Z" =>  array(),
        );

        foreach($games as $game) {
            $normalizedTitle = strtoupper($game->name);
            $normalizedTitle = preg_replace("/^THE ",\'\', $normalizedTitle,1);

            /* NOTE:    strncmp returns 0 if the comparison is EQUAL. 
                        We want equality in this case since we\'re 
                        sorting games into buckets based on first 
                        characters */
            if (strncmp($normalizedTitle, "A", 1) === 0) {
                $gameList["A"][$normalizedTitle] = $game;
            } else if (strncmp($normalizedTitle, "B", 1) === 0) {
                $gameList["B"][$normalizedTitle] = $game;
            } else if (strncmp($normalizedTitle, "C", 1) === 0) {
                $gameList["C"][$normalizedTitle] = $game;
            } else if (strncmp($normalizedTitle, "D", 1) === 0) {
                $gameList["D"][$normalizedTitle] = $game;
            } else if (strncmp($normalizedTitle, "E", 1) === 0) {
                $gameList["E"][$normalizedTitle] = $game;

我是这样做的，

WooCommerce sort by SKU

所以我试过了https://gist.github.com/bekarice/1883b7e678ec89cc8f4d 在我的网站上。只要所有产品都有SKU，效果就很好。如果产品没有SKU，则根本不会显示。也就是说，是否有其他方法可以按SKU排序，但不要求产品实际具有SKU？
