Question

我在产品上有不同的参数......但是我想只显示那些被用户点击的参数。我已经这样做了但我想删除重复...我的代码是： - < / p>

$ab=$_POST['data1'];
$karan=explode(",",$ab);
array_pop($karan);

for($i=0;$i<count($karan);$i++){
    'karan['.$i.'] = '.$karan[$i];

    $posts = $wpdb->get_results("SELECT * FROM demo_postmeta WHERE meta_value='".$karan[$i]."' ");

    $out=array();
    foreach($posts as $post){       


        if (!isset($out[$post->post_id])){

            $out[$post->post_id][$post->meta_key]=$out;



            $ram=get_the_post_thumbnail($post->post_id,"_thumbnail_id",true);
            $title=get_post_meta($post->post_id,"_product_title",true);
            $price=get_post_meta($post->post_id,"_product_year",true);
            $link=get_post_meta($post->post_id,"_product_likes",true);
?>

    }

Answer 1

<强>更新这可能是解决问题的一种方法：

if (!in_array($post->post_id, $out)){

        $out[] = $post->post_id;

您可以移除上一个$out[$post->post_id][$post->meta_key][] = $post->post_id;

Answer 2

只需将您需要的数据输入 $ out [$ post-＆gt; post_id] [$ post-＆gt; meta_key] [] =“您需要的数据”。并将此数组放在范围之外。就在死之前;

从for循环中的数组中删除重复的id
