按标签 Wordpress 元查询过滤器 [英] Meta Query Filter by Tag Wordpress

问题描述

我目前有多个页面，每个页面都有一个名为国家/地区"的自定义字段.

I currently have multiple pages, and in each page is a custom field which is named 'country'.

在国家/地区"字段中，我的值为英国、美国、巴西".

In the 'country' field I have this value 'uk, usa, brazil'.

我想要做的是在页面上显示带有我在自定义字段国家/地区"中列出的标签的帖子(在这种情况下，显示带有任何标签英国"、美国"和'巴西').

What I'm wanting to do is display posts on the page which have the tags I have listed in the custom field 'country' (In this case show posts which has any of the tags 'uk', 'usa' and 'brazil').

我有以下代码，但我不知道如何操作它来执行上述操作?

I have the following code, but I don't know how to manipulate it to do the above?

$args = array (
    'post_type'              => array( 'post' ),  // YOUR POST TYPE
    'meta_query'             => array(
        array(
            'key'       => 'country',  
            'value'     => $your_country,  // THE COUNTRY TO SEARCH
            'compare'   => 'LIKE',  // TO SEARCH THIS COUNTRY IN YOUR COMMA SEPERATED STRING
            'type'      => 'CHAR',
        ),
    ),
);

// The Query
$query = new WP_Query( $args );

似乎只是过滤单个值?

对实现上述目标的任何帮助将不胜感激.

Any help to achieve the above would be greatly appreciated.

推荐答案

我会设置一个自定义分类法来创建另一个名为国家/地区"的标签"版本，然后您可以改为执行分类法查询.

I'd setup a custom taxonomy to create another version of 'tags' called 'country', then you can do a taxonomy query instead.

有关创建自定义分类法的简单界面，请参阅自定义帖子类型 UI".

See 'Custom Post Type UI' for an easy interface to create a custom taxonomy.

https://wordpress.org/plugins/custom-post-type-ui/

1. 安装 CPT 用户界面(上面的插件).
2. 转到菜单中的添加/编辑分类法".添加国家"作为分类法.将其附加到您的post"post_type 和page".
3. 用您的国家/地区标签标记页面(用于显示帖子)和帖子".

然后您可以在页面模板中使用自定义 wp_query 来显示贴有国家/地区标签的帖子.

You can then use the custom wp_query in a page template, to show the posts, tagged with the country tag.

要获取与您的页面相关联的国家/地区条款的 ID:

To grab the ID's of the country terms, associated with your page:

$countryTerms = wp_get_post_terms($post->ID, 'country', array("fields" => "ids"));

$countryTerms = wp_get_post_terms($post->ID, 'country', array("fields" => "ids"));

然后更改您的查询参数以收集带有国家/地区标签的帖子.

Then change your Query arguments to gather the posts, tagged with the country.

$args = array(
    'post_type' => 'post',
    'tax_query' => array(
        array(
            'taxonomy' => 'country',
            'field'    => 'term_id',
            'terms'    => $countryTerms
        ),
    ),
);

如果您想坚持使用元字段，请尝试将您的TYPE"值更改为NUMERIC".

If you want to stick to a meta field, try changing your 'TYPE' value to 'NUMERIC'.
