Create WP user php in your WordPress site.

October 06 2018

Sometimes it is needed to create WP user php on a WordPress site. So that’s I’m going to write about this here.

I’ve divided this into two sections.

    • How to create a user in a Theme.
    • How to create a user in a plugin.

How to create WP user php.

we’ll need to use ‘after_setup_theme’ hook for that.

add_action(‘after_setup_theme’, ‘themeprefix_create_a_user’);
function themeprefix_create_a_user() {
	// let’s define some variable
  $user_name = ‘webextent’;
  $password   = ‘strong-pass-recommended’;
  $email = ‘[email protected]’;
  // let’s check if this user already exists or not, if not then pass
  If ( ! username_exists( $user_name ) ) {
	// wp_create_user() to create a user
	$user_ID = wp_create_user(  $user_name, $password, $email );
	// pass $user_ID to WP_User class
	$user = new WP_User( $user_ID );
	// define a role for the user
	$user->role( ‘administrator’); //you can use editor/author/contributor/subscriber
  }
}

Note : Most importantly update $user_name, $password and $email as your need. And delete the file after creating the user. And paste this code in functions.php

How to create a user from a plugin ( or a create MU plugin )

Let’s talk about how to create an MU ( must use ) plugin.
First of all, create a folder in wp-content/ called ‘mu-plugins’
Then create a ‘.php’ file in the folder, you can name it whatever you want.
But let’s name it ‘manage-users.php’ ( for example )
Then open the file in an editor

Certainly, we will use ‘init’ hook to create a user in our MU plugin
And follow the code below :

add_action(‘init’, ‘themeprefix_create_a_user’);
function themeprefix_create_a_user() {
	// let’s define some variable
  $user_name = ‘webextent’;
  $password   = ‘strong-pass-recommended’;
  $email = ‘[email protected]’;
  // let’s check if this user already exists or not, if not then pass
  If ( ! username_exists( $user_name ) ) {
	// wp_create_user() to create a user
	$user_ID = wp_create_user(  $user_name, $password, $email );
	// pass $user_ID to WP_User class
	$user = new WP_User( $user_ID );
	// define a role for the user
	$user->role( ‘administrator’); //you can use editor/author/contributor/subscriber
  }
}

Note: similarly we can use this method in any existing plugin as well.
