Question

stdClass Object
(
    [meta_id] => 11
    [post_id] => 8
    [meta_key] => wpp_gpid
    [meta_value] => gpid_1124779119
)
stdClass Object
(
    [meta_id] => 12
    [post_id] => 8
    [meta_key] => _edit_last
    [meta_value] => 1
)
stdClass Object
(
    [meta_id] => 13
    [post_id] => 8
    [meta_key] => _edit_lock
    [meta_value] => 1346228510:1
)
stdClass Object
(
    [meta_id] => 16
    [post_id] => 8
    [meta_key] => _thumbnail_id
    [meta_value] => 9
)

这是print_r值 $poster_meta = $wpdb->get_results("SELECT * FROM $wpdb->postmeta WHERE post_id = '{$poster}'");

如何获得meta_value和meta_key = thumbnail

的meta_key = _edit_last

Answer 1

将其视为一个对象。检查how objects工作。

foreach($poster_meta as $object){
    echo $object->meta_id."\n";
    echo $object->post_id."\n";
    echo $object->meta_key."\n";
    echo $object->meta_value."\n";
}

Answer 2

如果你想在wordpress中获取元键值，那么

试试这段代码： -

$team_counter = get_post_meta($post->ID, 'team_counter', true);

get_post_meta是wordpress库默认函数

如何获取stdClass Object foreach循环的值
