我在一些自定义PostType中有5组元框。所以我知道如何比较两个元框值。。。

Example:

\'meta_query\'        => array(
    \'relation\'  => \'AND\',
    array(
        \'key\'     => THEME_PREF.\'source_lang_1\',
        \'value\'   => $sourceLang,
        \'compare\' => \'=\'
    ),
    array(
        \'key\'     => THEME_PREF.\'target_lang_1\',
        \'value\'   => $targetLang,
        \'compare\' => \'=\'
    ),
),

But...
如果我需要检查4个字段怎么办-验证不正确<意味着它不会返回only the right results
只有同时满足这两个条件的“帖子”。

$transargs = array(
    \'post_type\'         =>  \'translators\',
    \'orderby\'           =>  \'date\',
    \'order\'             =>  \'DESC\',
    \'posts_per_page\'    =>  -1,
    \'meta_query\'        => array(
        \'relation\' => \'OR\',
        array(
            \'relation\' => \'AND\',
            array(
                \'key\'       =>  THEME_PREF.\'source_lang_1\',
                \'value\'     =>  $sourceLang,
                \'compare\'   =>  \'=\'
            ),
            array(
                \'key\'       =>  THEME_PREF.\'target_lang_1\',
                \'value\'     =>  $targetLang,
                \'compare\'   =>  \'=\'
            )
        ),
        array(
            \'relation\' => \'AND\',
            array(
                \'key\'       =>  THEME_PREF.\'source_lang_2\',
                \'value\'     =>  $sourceLang,
                \'compare\'   =>  \'=\'
            ),
            array(
                \'key\'       =>  THEME_PREF.\'target_lang_2\',
                \'value\'     =>  $targetLang,
                \'compare\'   =>  \'=\'
            )
        ),
    )   
);
$trns_query = new WP_Query($transargs);

To elaborate
我得到了很多结果，其中每个元查询的第一个条件都满足了，但第二个条件没有满足，因此

示例：$sourceLang=1
$targetLang=2；

i might also get<（这不好……和不起作用？）等于$sourcelang（1）/targetLang（5）的结果
