我正试图在wordpress之外的脚本上使用wordpress函数和$wbdb，但我不知道如何做到这一点。
我试过了：
require_once('./wp-load.php' ); // this is the correct path is tested.
class cron extends wpdb {
public function results(){
$sql = 'SELECT sub_id,email,cate_id FROM co_subsriber WHERE status = 0 ORDER BY sub_id ASC LIMIT '.$start.',750'; // $start =0
$records = $wpdb->get_results($sql);
}
}
我得到错误
Warning: Missing argument 1 for wpdb::__construct(), called in wp-db.php on line 578
Warning: Missing argument 2 for wpdb::__construct() called in wp-db.php on line 578
Warning: Missing argument 3 for wpdb::__construct() called in wp-db.php on line 578
Warning: Missing argument 4 for wpdb::__construct() called in wp-db.php on line 578
Notice: Undefined variable: dbuser wp-db.php on line 602 and all other pass, hostname...
无法选择数据库。。。。
我需要提到
require_once('./wp-load.php' );
并且使用简单的PHP，没有带类的OOP，它工作得很好。
那么我到底应该扩展什么类呢？
问题是您没有用正确的参数调用wpdb类的构造函数。
你需要做这样的事情：
class cron extends wpdb {
function __construct() {
parent::__construct( /* params here */ )
}
}
但这是完全不必要的，因为$wpdb已经在wp-load.php 中安装
只需这样做：
require_once('./wp-load.php' );
class Cron {
private $wpdb;
function __construct( $wpdb ) {
$this->wpdb = $wpdb;
}
public function results() {
$sql = 'SELECT sub_id,email,cate_id FROM co_subsriber WHERE status = 0 ORDER BY sub_id ASC LIMIT '.$start.',750'; // $start =0
$records = $this->wpdb->get_results($sql);
}
}
现在你安装你的类：
$cron = new Cron( $wpdb );
