wordpress仅包含wpdb（wpdb for ajax）

Posted 2021-02-23

So, you define a couple of fake funcs and require WP database config, after this you can require wp-db.php, create new wpdb and use it independency of WP for your ajax actions.

<?php
 
define('WP_DEBUG', false);
 
//fake funcs
function is_multisite() {return true;}
function apply_filters($tag, $value) { return $value; }
function wp_load_translations_early() {}
function __($text) { return $text; }
function wp_debug_backtrace_summary( $ignore_class, $skip_frames, $pretty) { return array(); }
//
 
$doc_root = $_SERVER['DOCUMENT_ROOT'];
require $doc_root . '/db-config.php';
require $doc_root . '/wp-includes/wp-db.php';
 
//Oh, Yeah!
$wpdb = new wpdb(DB_USER, DB_PASSWORD, DB_NAME, DB_HOST);
 
?>
