Question

好的，我已经搜索了很多这个问题......我无法让它发挥作用......

我有用户注册X类，事实是同一个用户可以在两个类中注册，所以我使用ACF复选框将其添加到配置文件中，到目前为止一直很好

问题在于，当我进行查询以调出分配给该类的任务时，它会在单个值时出现错误但在有多个值时会中断...

元查询的数组返回此

Array ( [0] => Array ( [key] => p_class [value] => tc [compare] => LIKE ) [1] => Array ( [key] => p_class [value] => yb [compare] => LIKE ) [2] => Array ( [key] => p_class [value] => m1 [compare] => LIKE ) [3] => Array ( [key] => p_class [value] => m2 [compare] => LIKE ) [4] => Array ( [key] => p_class [value] => m3 [compare] => LIKE ) )

这是我用来创建查询的代码......

请帮助!!

    if($_GET['uID']){
    $uData = get_userdata( $_GET['uID'] );
}else{
    $uData = wp_get_current_user(); 
}

$myClass = get_field('p_class', 'user_'.$uData->ID);
$meta_q = array();

foreach($myClass as $class){
    $meta_q[] = array(
        'key' => 'p_class',
        'value' => $class,
        'compare' => 'LIKE'
    );
}
print_r($meta_q);
$args = array(
    'post_type'  => 'task',
    'relation' => 'OR',
    'meta_query' => $meta_q
);



$the_query = new WP_Query( $args );

好吧..所以我终于找到了......希望这对任何人有帮助......

当你填写$ args数组时，你必须将[0]添加到$ meta_q数组......所以它看起来像这样......一切都很完美，除了这个：

$args = array(
'post_type'  => 'task',
'relation' => 'OR',
'meta_query' => $meta_q[0] 
);

具有多个值的元查询无效
