Question

这个帖子会变得很长，请耐心等待我！

我正在尝试构建一个自定义页面，该页面将用作＆＃34;目录＆＃34;我在后端创建的两种帖子类型。

这就是我尝试构建的内容：

到目前为止，我已经有了一个功能太大但它能完成工作（或至少差不多）。

所以我将首先发布HTML文件，然后分享我在自定义页面中使用的功能：

现在这里有与它一起工作的功能（我指出了问题出在哪里）：

    }

        // Don't sort by post date.

        // TRUE if we're sorting by year.
        $ob_year = false;

        foreach ( $orderby as $i => $s ) {
            // Sort posts by year.
            if ( 'year' === $s ) {

            // Sort posts by meta value en_emision from meta key estado_de_video. Note that this would only return

        $ok = isset( $orderby2 );

    }

    // by Year
    if ( ! is_numeric( $year ) ) {

    $q = new WP_Query( [
        'post_status' => $post_status,
        'post_type'   => array($post_type),
        'posts_per_page' => -1,
        'post_parent' => 0,
        'year'        => $year,
        'meta_key'    => isset( $meta_key ) ? $meta_key : '',
        'orderby'     => $orderby2,
        'order'       => $order,

    ] );

    if ( $q->have_posts() ) {
        echo '<ul>';
        while ( $q->have_posts() ) {
            $q->the_post();
            ?>
            <li><a href="<?php the_permalink(); ?>"><?php the_title() ?></a></li>
            <?php
        }
        echo '</ul>';
    } else {
        echo '<div class="alert alert-danger">Ningun Resultado</div>';
    }

    wp_die();
}

现在我想要的是按一个meta_key（estado_de_video）和我为该元键创建的两个meta_value（en_emision，en_final）排序。

现在使用上面的函数我尝试做类似的事情，就好像我按年份排序但是它没有用，然后我尝试稍微更改WP_Query：

有人试图帮助我这个建议：

$q = new WP_Query( [
        'post_status' => $post_status,
        'post_type'   => array($post_type),
        'posts_per_page' => -1,
        'post_parent' => 0,
        'year'        => $year,
        'orderby'     => 'meta_value', //SET THIS AS REQUIRED
        'order'       => $order,

    ] );
if ( isset( $meta_key ) && '' != $meta_key ) {
    $q['meta_key'] = 'estado_de_video';
    $q['meta_value'] = $meta_key;
}

因为我已经被告知这应该以某种方式解决，或者至少它应该返回带有meta_value（en_emision或en_final）的帖子，但它没有，然后我试图改变通过删除评论部分（参见上面的功能片段）并删除它来实现：

if ( isset( $meta_key ) && '' != $meta_key ) {
    $q['meta_key'] = 'estado_de_video';
    $q['meta_value'] = $meta_key;
}

因此，一旦删除了这些内容，我就尝试更改WP_Query：

$q = new WP_Query( [
        'post_status' => $post_status,
        'post_type'   => array($post_type),
        'posts_per_page' => -1,
        'post_parent' => 0,
        'year'        => $year,
        'orderby'     => 'meta_value', //SET THIS AS REQUIRED
//        'meta_key'    => $meta_key,
//        'meta_value'  => $meta_values,
        'order'       => $order,
        'meta_query' => array(
            'relation' => 'AND',
            array(
                'key' => 'estado_de_video',
                'value' => array('en_emision', 'en_final'),
                'compare'   => 'EXISTS'
            ),
        ),

] );

还没有成功。有人可以指导我，或者至少告诉我一个更好的方法吗？

提前致谢。

以下这个BLOCKQUOTE并不是必须提供帮助但是如果有人决定，则表示赞赏。

我需要第二个<select>的帮助;我希望根据选择的帖子类型显示分类法。例如：

CPT的{p> <select> 1：Peliculas，

<select> 2：从选定的帖子类型中加载类别分类。

让我们说我选择了＃34; Peliculas＆＃34;那么我希望自定义分类中所做的所有类别都附加在＆＃34; Peliculas＆＃34;。

现在我有两个CPT，一个叫做动漫，另一个叫做peliculas

＆＃34;动画及＃34;有＆＃34; categorias_anime＆＃34;分类，

＆＃34; peliculas＆＃34;拥有＆＃34; categorias_movie＆＃34;分类

提前致谢。

Answer 1

按给定的meta_value排序很简单，不需要复杂的查询。我看到你混淆了给定代码中的元键和值。

请使用：

$q = new WP_Query( [
        'post_status' => $post_status,
        'post_type'   => array($post_type),
        'posts_per_page' => -1,
        'post_parent' => 0,
        'year'        => $year,
        'orderby'     => 'meta_value',
        'meta_key' => 'estado_de_video',
        'order'       => $order, //ASC or DESC
    ] );

这就是全部。无需在此处设置meta_value参数。
