In WordPress the $wpdb object can talk to any number of tables, but only within database WordPress is installed. In case you need to connect to another database, you will have to instantiate your own object from the wpdb class with the appropriate connection details:<\/p>\n
$mydb = new wpdb( 'username' , 'password' , 'database' , 'localhost' );<\/pre>\n <\/p>\n
Once the connection is made you can access the database and its tables as you would in any WordPress database:<\/p>\n
$rows = $mydb->get_results(\"SELECT field1,field2 FROM myTable WHERE field3=1\");\r\nforeach ($rows as $row) {\r\n echo $row->field1;\r\n}<\/pre>\nThis code can be in plugins, templates, themes and almost anywhere else inside the WordPress code.<\/p>\n\n\n","protected":false},"excerpt":{"rendered":"
