我正在创建事件生成器插件。我已经创建了在主页上显示所有事件名称的快捷码。现在单击事件名称，我想显示该事件的描述。如何在插件中做到这一点？下面是我的代码：

function event_display(){?>

<?php global $wpdb;
    $myrows = $wpdb->get_results( "SELECT event_cat_id, event_cat_name FROM tcm_event_category" ); 
    foreach($myrows as $myrow){
        echo "<h3>".$myrow->event_cat_name."</h3>";
        $evetcatid = $myrow->event_cat_id; 
        $myevents = $wpdb->get_results( "SELECT event_id, event_name, event_desc, event_short_desc, event_startDate, event_bookFee FROM tcm_event WHERE event_catt_id=$evetcatid" ); 
        foreach($myevents as $myevent){
            echo "<div class=\'event\' style=\'\'>";
            echo "<p style=\'width:100%;\'><a href=\'?detail_event_display($myevent->event_id)\'>".$myevent->event_name."</a></p>";
            echo "<p style=\'width:70%;float:left;\'>".$myevent->event_short_desc."</p>";
            echo "<p style=\'width:30%;float:right;\'>".$myevent->event_startDate."</p>";
            echo "<p style=\'width:30%;float:right;\'> Rs. ".$myevent->event_bookFee."</p>";
            echo "</div>";
        }
    }
}
function detail_event_display($eventid){
    echo $eventid;
}
add_shortcode(\'events\', \'event_display\');
