我正在为插件添加一个选项。我想在摘要生成器返回curent test变量后添加一个子ix。

所以我的数据在摘录变量中，我想添加变量$summarizer\\u add\\u html\\u trust\\u bulletpoints中的文本。

我该怎么做？

function create_excerpt_product($post_ID)  {
    global $wpdb;

    $excerpt = $wpdb->get_var("SELECT post_excerpt FROM $wpdb->posts WHERE ID = $post_ID");
    if(!$excerpt && !$force_rewrite_excerpt) {        
        require_once(\'config.php\');
        
        // load the correct Document class for the language specified
        require_once("lib/$lang/$document[$lang].php");

        $content = $wpdb->get_var("SELECT post_content FROM $wpdb->posts WHERE ID = $post_ID"); 
        $title = $wpdb->get_var("SELECT post_title FROM $wpdb->posts WHERE ID = $post_ID");        
        
        $doc = new $document[$lang]($title, $content);
        
        // TODO add tags, category and others to the query
        $summarizer_add_html_trust_bulletpoints=\'my demo text\' ;

        $excerpt = $doc->getSummary($summary_options);
        //$excerpt = $excerpt + $summarizer_add_html_trust_bulletpoints ;
        $excerpt = esc_sql($excerpt);
        
            $wpdb->query("UPDATE $wpdb->posts SET post_excerpt = \'$excerpt\' WHERE ID = $post_ID");
        
    }
}

?>
