在wordpress中显示特定uid的多个条目

我想显示特定uid的多个条目

这是我的函数，但它不能显示任何值

function anscount()
{
    global $wpdb;
        $table_name = $wpdb->prefix.'pte_quiz';
                $sql = "SELECT Count(*) AS count FROM $table_name WHERE uid =1";
                    echo "Count Number: ";
}
add_action('init','anscount');

试着这样做，兄弟：

function anscount()
{
    global $wpdb;
    $table_name = $wpdb->prefix.'pte_quiz';
    $sql = "SELECT Count(*) AS count FROM $table_name WHERE uid =1";
    $myrow = $wpdb->get_results($sql);
    if (isset($myrow[0]) && isset($myrow[0]->count)) {
        echo "Count Number: ".$myrow[0]->count;
    }
}
add_action('init','anscount');

您需要先运行$sql，然后再打印。。！
