mysql - reading from a database using WordPress

Question

I am very new to WordPress, I have very little knowledge with PHP. I read about PODS and I know how to create one and use pages / templates to display data.

The issue I am havingis, the PODS I was creating use static data entered via the WP dashboard, what I want is to read data from a database, I am using MySql (same DB that wordpress is using). is there a way to use PODS and read the data from the DB, or wordpress has a better way to handle data coming from the DB ?

Thanks

您应该查看 $wpdb 变量（和类）
http://codex.wordpress.org/Class_Reference/wpdb

请记住将其声明为全局：

<?php global $wpdb; ?>

但是我不确定你想要什么。
我建议靠近 wordpress。
如果您想在不使用代码的情况下创建自己的自定义帖子类型，请使用moretypes

在 WordPress 中读取数据库的常用方法如下：

获取全局变量 $wpdb
```
全球 $wpdb
```

准备输出和 SQL 命令

$输出 = "";
$sql = "SELECT ".$wpdb->prefix."posts.post_title,
“.$wpdb->前缀。”posts.post_name FROM “。
$wpdb->prefix."posts WHERE ".$wpdb->prefix."
"posts.post_status='publish' AND ".$wpdb->prefix.
“posts.post_parent=0 和”.$wpdb-> 前缀。
"posts.post_type='sometype'";

方法 get_results() 从 db 检索值

$posts = $wpdb->get_results($sql);
$输出 .= '';
foreach ($posts 作为 $post) {
$输出 .= 'post_name）。
'">'.strip_tags($post->post_title).'';
}
$输出 .= '';
回声$输出；

Wordpress CSM 有一个非常好的类来使用 db，我认为最好的办法是学习 db 如何连接并从 mysql 获取数据
