如何获取我这样创建的表:
global $wpdb; //Get all the wordpress database stuff
$table_prefix = $wpdb->base_prefix; //Get the global prefix for all sites (on a multisite installation)
$table_name = $table_prefix.\'wpaa\';//Add wpaa behind the prefix
$sql = "CREATE TABLE IF NOT EXISTS `".$table_name."` (....) "; //Create table and its rows. (Rows are ...\'d out)
require_once( ABSPATH . \'wp-admin/includes/upgrade.php\' ); //Require something you have to include
dbDelta( $sql ); //Make the actual query
并以数组的形式从中获取所有数据。我知道在普通PHP中该怎么做(没有wordpress):
$sql = \'SELECT id,foo,bar FROM wp_wpaa\';
$result = mysql_query($sql) or die(\'Error at looking up in database\');
$array = mysql_fetch_array($result);
