从wordpress数据库检索排序

Question

我有一个wordpress网站，我正试图从按字母顺序(希腊语)的表中获得结果。我试过了，但没有用。我想我错过了什么，但我想不起来。下面是代码:

if($homeplayers) {
    asort($homeplayers);
    $i = 1; foreach ($homeplayers as $homeplayer) {
        $output .= '<tr>';
        $output .= '<td style="vertical-align:top;word-wrap:break-word;">';
        $output .= leagueengine_fetch_player_emblem($homeplayer->player_id).leagueengine_fetch_data_from_id($homeplayer->player_id,'data_value' );
        $output .= '</td>';
        $output .= '<td style="text-align:center;vertical-align:top;">';
        if(isset($_POST['import_last_home_lineups']) && in_array($homeplayer->player_id, $home_app)) {      
            $output .= '<input class="homeplayers" name="homeplayers[]" type="checkbox" checked="checked" value="'.$homeplayer->player_id.'">';
        } else {
            $output .= '<input class="homeplayers" name="homeplayers[]" type="checkbox" '.leagueengine_isplaying_tournament($tournament_id,$match_id,$homeplayer->player_id).' value="'.$homeplayer->player_id.'">';
        }
        $output .= '</td>';                 
        $i++;
    }
    $output .= '<td></td>';
    $output .= '</tr>';
}

您正在尝试使用asort对对象进行排序，但是该函数不知道您希望如何排序....您需要一个自定义排序函数

usort($homeplayers, "sorter");
function sorter($a,$b){
    // assuming ->player_name is the correct variable
    return strcmp($a->player_name, $b->player_name);
}
