Enabling & Installing Posts to Posts When a New Blog Is Created

The other day I came across an issue where Posts to Posts requires an administrator or someone with `manage_options` capability in order to install Posts to Posts table on a new blog creation. This does not work if all new sites create the default user as an Editor, and you need to immediately make Posts to Posts available for immediate use.

So here is the code that I used in order to make this possible.

<?php
add_action( 'wpmu_new_blog', 'wps_install_p2p', 5, 6 );
/**
* Create P2P table on site creation regardless of admin presence.
*
* @see P2P_Tools_Page::maybe_install()
* @author Travis Smith <wpsmith.net>
*
* @param int $blog_id Blog ID.
* @param int $user_id User ID.
* @param string $domain Domain.
* @param string $path Path to domain.
* @param int $site_id Site ID.
* @param array $meta Site Meta.
*
*/
function wps_install_p2p( $blog_id, $user_id, $domain, $path, $site_id, $meta ) {
switch_to_blog( $blog_id );
$current_ver = get_option( 'p2p_storage' );
if ( $current_ver == P2P_Storage::$version ) {
return;
}
P2P_Storage::install();
update_option( 'p2p_storage', P2P_Storage::$version );
restore_current_blog();
}

Setting Up a Local Environment via XAMPP: Installing WordPress via Download

4. Download WordPress

Go to wordpress.org and download the latest build of WordPress. Go to the htdocs folder (where you installed the XAMPP), extract the wordpress.zip to a new folder (eg. mywordpress).

5. Run the Famous WordPress 5-minute Installation (install.php)

With your browser, go to http://localhost/mywordpress/wp-admin/install.php or http://localhost:8080/mywordpress/wp-admin/install.php, click Create a Configuration File and click Let's go! Fill out Database Name (eg., wordpress), User Name (needs to be root), Password, Database Host, and Table Prefix (it is always a best practice to change the default wp_ prefix to something else). Be sure the User Name is the same as your mySQL username, "root". Then click Run the Install, and follow the instructions to install WordPress. Fill in the Site Title, Username, Password twice, and email. Then click Install, and then Login.

Setting Up a Local Environment via XAMPP: Security

3. Setup XAMPP Security

Go back to localhost or localhost:8080 in your web browser. Click on security and it will open a new window/tab to http://localhost/security/index.php or http://localhost:8080/security/index.php.

Then click on the link: http://localhost/security/xamppsecurity.php. This will allow you to change your mySQL password and .htaccess password. Since this is typically my sandbox for breaking things and developing code, I just enter a mySQL password. Click password changing and you will receive a message: The root password was successfully changed. Please restart MYSQL for loading these changes! Then close the window/tab.

Setting Up a Local Environment via XAMPP: Error with Port 80 & Skype

If when you install it, port 80 is busy. This could be because of another program (like Skype) or your corporate network. So, if you have Skype installed, I recommend changing Skype's default port. It simply makes everything easier.

Open Tools > Options
Skype Options

Click Advanced
Options Screen

Click on Connection
Advanced Settings

Uncheck "Use port 80 and 443 as alternatives for incoming connections".
"Advanced Connection"/>
"Advanced Connection Remove port 80"/>

Click Save
Save Advanced Settings

Using a Different Port

Setting Up a Local Environment via XAMPP: Launching Apache & MySQL

Next we will launch Apache & MySQL. To do this easily, open the Control Panel.
XAMPP Control Panel

Click Start on both Apache and MySQL.
XAMPP Control Panel Start Apache
XAMPP Control Panel Apache Started

XAMPP Control Panel Start MySQL
XAMPP Control Panel MySQL Started

Now, if you want, you can install Apache and your local webserver to another port like 8080. To change the port, you want to navigate to your XAMPP directory (e.g., C:/xampp/apache/conf) and open the file httpd.conf in your text editor. On line 45, you'll find:

#Listen 0.0.0.0:80
#Listen [::]:80
Listen 80

To change it to port 8080, simply make this change:

Listen 0.0.0.0:8080
#Listen [::]:80
#Listen 80
view raw httpd-new.conf hosted with ❤ by GitHub

Then later, on line 176, you'll see:

ServerName localhost:80

Change it to:

ServerName localhost:8080

If you switch to port 8080, you'll need to to always go to it via localhost:8080. Furthermore, WordPress will not allow you to enable multisite locally with a port number trailing localhost. It will redirect you to http://localhost/xampp/ or http://localhost:8080/xampp/.

You're host directory will be C:/xampp/htdocs based on httpd.conf. If you wish to change it, simply find it in httpd.conf on line 183 and make whatever changes you'd like.
