自定义张贴随机Wordpress

你好，我在随机显示帖子时遇到问题。帖子列得几乎正确，我正在做一个条件meta_quey来从自定义帖子中捕获2个数据，并且确实可以提取内容，但rand属性的orderby只更改了位置的前2个帖子，我想随机生成所有帖子。有人对此有解决方案吗？

感谢您的帮助！

$args2 = array (
'post_type' => 'garotas',
'meta_query' => array(
                 'relation' => 'AND',
                 array(
                   'key' => 'cidade',
                   'value' => 'SL',
                   // 'compare' => 'LIKE'
                 ),
                 array(
                   'key' => 'garotastop',
                   'value' => 1,
                   // 'compare' => 'LIKE'
                 )
             ),
'posts_per_page' => -1,
'orderby' => 'rand',
'order'    => 'ASC',
);
$event_query2 = new WP_Query( $args2 );

// The Query
$the_query2 = new WP_Query( $args2 );
// The Loop
if ( $the_query2->have_posts() ) {

  while ( $the_query2->have_posts() ) {
$the_query2->the_post();
$title = get_the_title();
$separator = "-";
$title2 = str_replace(" ", $separator, $title);
$width = 300;
$height = 700;

echo '<li class="col-md-4"><h1 class="title5 conteudoTitulo cor1 title-list"><a href="http://garotasjp.com.br/garotas/'.$title2.'">' . get_the_title() . '</a></h1>';
echo "<div class='thumbnail3'>";
$garotastop1 = get_post_meta( $post->ID,'garotastop1', true );
$imageUrl = wp_get_attachment_image_src($garotastop1, full);
echo '<a href="http://garotasjp.com.br/garotas/'.tirarAcentos($title2).'"><img class="img-responsive" width="'.$width.'" height="'.$height.'" src="'.$imageUrl[0].'"/></a>';
echo "</div>";
echo "</li>";
}
