使用自定义字段筛选器创建WP存档
因此，我正在尝试创建一个高级自定义过滤器专业插件的过滤器，在自定义帖子类型存档页面上，但它不过滤。它会更改URL，尽管它会列出页面上的所有项目，而不考虑所选内容。
我正在尝试按照本教程进行复制：https://www.advancedcustomfields.com/resources/creating-wp-archive-custom-field-filter/
我已经使用以下内容设置了unctions.php：
<?php
function theme_enqueue_styles() {
wp_enqueue_style( 'aerious-parent-stylesheet', get_template_directory_uri() . '/style.css', array( 'aerious-google-fonts', 'aerious-libs' ) );
}
add_action( 'wp_enqueue_scripts', 'theme_enqueue_styles' );
function aerious_child_lang_setup() {
$lang = get_stylesheet_directory() . '/languages';
load_child_theme_textdomain( 'aerious', $lang );
}
add_action( 'after_setup_theme', 'aerious_child_lang_setup' );
// Houses Custom Posttype
$labels = array(
'name' => 'Houses',
'singular_name' => 'House',
'add_new' => 'Add New',
'add_new_item' => 'Add New House',
'edit_item' => 'Edit Houses',
'new_item' => 'New House',
'all_items' => 'All Houses',
'view_item' => 'View House',
'search_items' => 'Search Houses',
'not_found' => 'No houses found',
'not_found_in_trash' => 'No houses found in Trash',
'parent_item_colon' => '',
'menu_name' => 'Houses',
);
$args = array(
'labels' => $labels,
'public' => true,
'publicly_queryable' => true,
'show_ui' => true,
'show_in_menu' => true,
'query_var' => true,
'rewrite' => array( 'slug' => 'houses' ),
'capability_type' => 'post',
'has_archive' => true,
'hierarchical' => false,
'supports' => array('title', 'editor', 'author', 'thumbnal')
);
register_post_type( 'house', $args);
// Custom Posttype Filter
// array of filters (field key => field name)
$GLOBALS['my_query_filters'] = array(
'field_5d1cafdb2f7d4' => 'bedrooms'
);
// action
add_action('pre_get_posts', 'my_pre_get_posts', 10, 1);
function my_pre_get_posts( $query ) {
// bail early if is in admin
if( is_admin() ) return;
// bail early if not main query
// - allows custom code / plugins to continue working
if( !$query->is_main_query() ) return;
// get meta query
$meta_query = $query->get('meta_query');
// loop over filters
foreach( $GLOBALS['my_query_filters'] as $key => $name ) {
// continue if not found in url
if( empty($_GET[ $name ]) ) {
continue;
}
// get the value for this filter
// eg: http://www.website.com/events?city=melbourne,sydney
$value = explode(',', $_GET[ $name ]);
// append meta query
$meta_query = array(
'key' => $name,
'value' => $value,
'compare' => 'IN',
);
}
// update meta query
$query->set('meta_query', $meta_query);
// echo '<pre>';
// var_dump($query->query_vars);
// echo '</pre>';
}
和我的存档-house.php：
<?php

调试方式：

结果：

解决方案
好的，我已经解决了问题！
在函数.php中，教程要求编写
// append meta query
$meta_query[] = array(
'key' => $name,
'value' => $value,
'compare' => 'IN',
);
但我们需要
// append meta query
$meta_query = [];
$meta_query[] = array(
'key' => $name,
'value' => $value,
'compare' => 'IN',
);
不管怎样，谢谢你的帮助！
