我正在使用ACF advanced custom fields插件为我的CPT创建自定义字段，我将我的CPT的内容编辑器替换为来自ACF的自定义Wysiwyg编辑器字段（字段名称：full\\u text），我在其中输入CPT的主文本（出于特定原因，我确实需要它）。但是，当我尝试使用toc+从自定义字段编辑器中的文本生成一个内容表时，它没有显示任何内容。实际上，他们在插件页面上写道：

Custom post types are supported, however, auto insertion works only when `the_content()` has been used by the custom post type. Each post type will appear in the options panel, so enable the ones you want.

在插件toc中。php文件我注意到：

        public function extract_headings( &$find, &$replace, $content = \'\' )
    {
        $matches = array();
        $anchor = \'\';
        $items = false; 
        // reset the internal collision collection as the_content may have been triggered elsewhere
        // eg by themes or other plugins that need to read in content such as metadata fields in
        // the head html tag, or to provide descriptions to twitter/facebook
        $this->collision_collector = array();
        if ( is_array($find) && is_array($replace) && $content ) {
            // get all headings
            // the html spec allows for a maximum of 6 heading depths
            if ( preg_match_all(\'/(<h([1-6]{1})[^>]*>).*<\\/h\\2>/msuU\', $content, $matches, PREG_SET_ORDER) ) {
                // remove undesired headings (if any) as defined by heading_levels
                if ( count($this->options[\'heading_levels\']) != 6 ) {
                    $new_matches = array();
                    for ($i = 0; $i < count($matches); $i++) {
                        if ( in_array($matches[$i][2], $this->options[\'heading_levels\']) )

您可以注意到该函数与$content. 但是有没有办法让它与使用ACF创建的自定义字段一起工作？或者，你有什么建议来解决这个问题吗？

add_action( \'acf/save_post\', \'wpse199256\', 20 );

function wpse199256( $post_ID ) {
    global $wpdb;
    $post = get_post( $post_ID );
    $wpdb->update( $wpdb->posts, array( \'post_content\' => get_field( \'full_text\', $post_ID ), array( \'ID\' => $post_id ) );
}
