这个把我难住了。
我正在将
wp_posts > post_contentpost_content我正在尝试过滤加载到经典编辑器或块编辑器中的内容，因此内容实际上是从名为
post_contentwp_posts我已经尝试过这 3 个过滤器和操作（不同时且没有运气）...
add_action('edit_form_after_title', [ $this, 'load_custom_post_content_editor' ]);
public function load_custom_post_content_editor($post) {
// Check if the post type is 'post' or 'page'
if (in_array($post->post_type, array('post', 'page'))) {
$custom_post_content = get_post_meta($post->ID, 'post_content', true);
if (!empty($custom_post_content)) {
$post->post_content = $custom_post_content;
}
}
}
add_action('wp_insert_post_data', [ $this, 'modify_post_data' ], 10, 2);
public function modify_post_data($data, $postarr) {
// Check if the post type is allowed.
if (in_array($data['post_type'], self::$allowed_post_types)) {
$custom_post_content = get_post_meta($postarr['ID'], 'post_content', true);
if (!empty($custom_post_content)) {
$data['post_content'] = $custom_post_content;
}
}
return $data;
}
add_filter('block_editor_content', [ $this, 'filter_block_editor_content' ], 10, 2);
public function filter_block_editor_content($content, $post) {
// Check if the post type is allowed.
if ($post && in_array($post->post_type, self::$allowed_post_types)) {
$custom_post_content = get_post_meta($post->ID, 'post_content', true);
if (!empty($custom_post_content)) {
$content = $custom_post_content;
}
}
return $content;
}
这些都没有成功从 WordPress 编辑器中的自定义字段加载内容，即使“post_content”自定义字段存在且字段内包含块编辑器内容代码。
这里，我的其他工作人员在管理中保存帖子/页面时，将帖子内容卸载到名为
post_content<?php

如果有人对如何过滤编辑器中的内容以从自定义字段加载数据有任何建议，那将非常有帮助。
class WP_JSON_Search {
// ... (existing code)
public function __construct () {
// Use 'edit_form_after_title' action to load custom post content into the editor.
add_action('edit_form_after_title', [ $this, 'load_custom_post_content_editor' ]);
// Use 'save_post' action to save post_content to the custom meta field.
add_action('save_post', [ $this, 'save_post_content' ], 10, 2);
// Use 'the_content' filter to filter the content in the editor.
add_filter('the_content', [ $this, 'filter_the_content' ]);
}
public function load_custom_post_content_editor($post) {
// Check if the post type is 'post' or 'page'
if (in_array($post->post_type, array('post', 'page'))) {
$custom_post_content = get_post_meta($post->ID, 'post_content', true);
if (!empty($custom_post_content)) {
$post->post_content = $custom_post_content;
}
}
}
public function save_post_content($post_id, $post): void
{
// Check if the post type is allowed.
if (in_array($post->post_type, self::$allowed_post_types)) {
// Set the post_content to the custom meta field.
$post_content = $post->post_content;
update_post_meta($post_id, 'post_content', $post_content);
$post->post_content = ''; // Empty the default post_content field.
}
}
public function filter_the_content($content): mixed
{
// Get the current post.
global $post;
// Check if the post type is allowed.
if ($post && in_array($post->post_type, self::$allowed_post_types)) {
// Get the post_content from the custom meta field.
$custom_post_content = get_post_meta($post->ID, 'post_content', true);
if (!empty($custom_post_content)) {
$content = $custom_post_content;
}
}
// Return the content.
return $content;
}
}
new WP_JSON_Search();
所做的更改：
Used edit_form_after_title action to load custom post content into the editor. This action occurs before the editor is displayed.
Removed the remove_action and wp_update_post calls from the save_post_content method. They were causing unnecessary recursion and might interfere with the expected behavior.
