July 31, 2017 By Editorial Staff in WordPress 1 Comment Tags: Code, Code Snippet, Snippet, WordPress, WordPress Snippet, WordPress Snippets

The following snippet will let you share databases between two domains in WordPress.

Install the second WP as normal into the same database as the original with a DIFFERENT table prefix. Activate the theme you want to use.

In wp-config:

define('CUSTOM_CAPABILITIES_PREFIX', 'wp_');
define('CUSTOM_USER_TABLE', 'wp_users');
define('CUSTOM_USER_META_TABLE', 'wp_usermeta');
In wp-includes/capabilities.php:
/**
	 * Set up capability object properties.
	 *
	 * Will set the value for the 'cap_key' property to current database table
	 * prefix, followed by 'capabilities'. Will then check to see if the
	 * property matching the 'cap_key' exists and is an array. If so, it will be
	 * used.
	 *
	 * @since 2.1.0
	 *
	 * @param string $cap_key Optional capability key
	 * @access protected
	 */
	function _init_caps( $cap_key = '' ) {
		global $wpdb;
		if ( empty($cap_key) )
			if (defined ('CUSTOM_CAPABILITIES_PREFIX')) {
    	  $this->cap_key = CUSTOM_CAPABILITIES_PREFIX . 'capabilities';
    	} else {
        $this->cap_key = $wpdb->prefix . 'capabilities';
    	}
		else
			$this->cap_key = $cap_key;
		$this->caps = &$this->{$this->cap_key};
		if ( ! is_array( $this->caps ) )
			$this->caps = array();
		$this->get_role_caps();
	}
In the active theme's functions.php:
function table_prefix_switch() {
    global $wpdb;
    $options = $wpdb->options; //Save the site 2 options table
    $wpdb->set_prefix('wp_'); //The prefix to site 1
    $wpdb->options = $options; //Put the options table back
}
add_action('init', 'table_prefix_switch');

define('CUSTOM_CAPABILITIES_PREFIX', 'wp_');

define('CUSTOM_USER_TABLE', 'wp_users');

define('CUSTOM_USER_META_TABLE', 'wp_usermeta');

In wp-includes/capabilities.php:

/**

* Set up capability object properties.

* Will set the value for the 'cap_key' property to current database table

* prefix, followed by 'capabilities'. Will then check to see if the

* property matching the 'cap_key' exists and is an array. If so, it will be

function _init_caps( $cap_key = '' ) {

global $wpdb;

if ( empty($cap_key) )

if (defined ('CUSTOM_CAPABILITIES_PREFIX')) {

$this->cap_key = CUSTOM_CAPABILITIES_PREFIX . 'capabilities';

} else {

$this->cap_key = $wpdb->prefix . 'capabilities';

}

else

$this->cap_key = $cap_key;

$this->caps = &$this->{$this->cap_key};

if ( ! is_array( $this->caps ) )

$this->caps = array();

$this->get_role_caps();

}

In the active theme's functions.php:

function table_prefix_switch() {

global $wpdb;

$options = $wpdb->options; //Save the site 2 options table

$wpdb->set_prefix('wp_'); //The prefix to site 1

$wpdb->options = $options; //Put the options table back

}

add_action('init', 'table_prefix_switch');
