在同一頁面中運行自定義短代碼兩次

Question

我需要wordpress問題的幫助。

我創建的檢索與特定paramenter表內數據列表的自定義簡碼：

add_shortcode("archive", "archive_render"); 
function archive_render($atts) { 

extract(shortcode_atts(array(
    "rientro" => "no", 
    "year" => "", 
), $atts)); 

global $wpdb; 

$rientro == "si" ? $rientro = "yes" : "no"; 

$query = "SELECT event_name FROM wp_em_events WHERE EXTRACT(YEAR FROM event_end_date) = ".$year." AND event_end_date < CURDATE()"; 
$pasts_event = $wpdb->get_col($query); 

function get_pasts_event($pasts_event){ 

    foreach ($pasts_event as $past_event_slug) { 
     $output .= "<li><a href='".get_site_url()."/eventi/".$past_event_slug."'>$past_event_slug</a></li>"; 
    } 

    return $output; 
} 

$string = '[one_third last="'.$rientro.'" class="" id=""][accordian class="" id=""][toggle title="'.$year.'" open="no"]<ul>'.get_pasts_event($pasts_event).'</ul>[/toggle][/accordian][/one_third]'; 

echo do_shortcode($string); 

}

我要檢索與當前日期相比，有過去的日期的所有事件。

如果我在頁面中添加兩次短代碼，只有第一個短代碼有效，頁面停止顯示其餘內容。

有人可以幫我解決這個問題嗎？

WordPress的簡碼應返回一個字符串，而不是附和它 讓我重新安排你的代碼

function get_pasts_event($pasts_event){ 

    foreach ($pasts_event as $past_event_slug) { 
     $output .= "<li><a href='".get_site_url()."/eventi/".$past_event_slug."'>$past_event_slug</a></li>"; 
    } 

    return $output; 
} 

add_shortcode("archive", "archive_render"); 
function archive_render($atts) { 

    extract(shortcode_atts(array(
     "rientro" => "no", 
     "year" => "", 
     ), $atts)); 

    global $wpdb; 

    $rientro == "si" ? $rientro = "yes" : "no"; 

    $query = "SELECT event_name FROM wp_em_events WHERE EXTRACT(YEAR FROM event_end_date) = ".$year." AND event_end_date < CURDATE()"; 
    $pasts_event = $wpdb->get_col($query); 


    $string = '[one_third last="'.$rientro.'" class="" id=""][accordian class="" id=""][toggle title="'.$year.'" open="no"]<ul>'.get_pasts_event($pasts_event).'</ul>[/toggle][/accordian][/one_third]'; 

    return $string; 
}
