WordPress Development Stack Exchange is a question and answer site for WordPress developers and administrators. It's 100% free, no registration required.

I have a question concerning creating a new user. I'm creating a plugin for this wp site I am working on. I have set up custom roles for these and I'd like to have a separate menu item for the "Owner" role to be able to access and add new staff members. I'd use the add users menu but I'd like to customize it to say "Staff" and "Add New Staff" but I can't do that, I don't think. So, I've opted for this route. Anyway... I've tried copying over the context of the "user-new.php" and "users.php" and change paths but I continue to run into errors. I've tried copying over stuff viewing the source but that hasn't worked either. I'd like pretty much the same exact setup... maybe excluding "Administrator" role from the options. Any pointers on this would be greatly appreciated. Thank you in advance to anyone that can help!

EDIT:

I have my core file with an include require_once 'includes/plugin_hooks.php'; Then in my plugin_hooks.php I have this written out:

//Eleven34 Studios Staff Manager Menu

function e34s_staff_plugin_menu() {
    add_menu_page('Staff','Staff','read','e34s-staff','e34s_staff_list',
    '/wordpress/wp-content/plugins/e34s_time_card/includes/images/e34s_staff_icon.png',22);
}

function e34s_staff_list() {
        include ('staff/staff.php');
}

add_action('admin_menu','e34s_staff_plugin_menu');

//Submenu items
function e34s_staff_plugin_add_staff() {
    add_submenu_page( 'e34s-staff', 'Add Staff', 'Add Staff', 'read', 'e34s_staff_add_staff', 'e34s_staff_add_staff_callback' ); 
}

function e34s_staff_add_staff_callback() {
        include ('staff/add_staff.php');
}

add_action('admin_menu', 'e34s_staff_plugin_add_staff');

Then after the user is added successfully I want it to redirect to the staff page that lists all of the staff members.

Important: The code posted below is not fully tested. There are lots of area where you can improve the code as this is only to show you the right way. If you need any pointer, check user-new.php as the reference.

I am going to use the class structure for the plugin and let's say plugin name is create-user. So, the basic structure of this plugin will be:

<?php
/*
Plugin Name: Create User
Description: Create user
Plugin URI: ****
Author: sakibmoon
Author URI: ****
Version: 0.0.1
*/
class  create_user{

}

At first we have to create the Admin menu page. We are going to add that in the constructor.

public function __construct(){
    //Action hook to add menu option in the admin panel
    add_action('admin_menu', array( &$this, 'add_menu') );
}

The add_menu() function is as follow

public function add_menu(){
    //Creating top level menu as staff
    //Use add_submenu_page for adding additional submenu
    add_menu_page( 'Staff', 'staff', 'edit_users', __FILE__, array( &$this, 'show_staff_page' ) );
    }

show_staff_page() function will show the page content. We will show the form to create user as page content. I have taken almost all the portion from the user-new.php with the exception of role. By default, wordpress use wp_dropdown_roles() to populate the drop down field. But if you wanted to exclude Administrator you can't call it directly. You have to remove Administrator from editable_roles. To save time, I have hard coded it. But in my opinion best choice would be to use the filter editable_roles. How to remove administrator role in settings -> general -> New User Default Role? will give you some idea about this.

public function show_staff_page(){
?>
    <?php //Input to create new User ?>
    <form action="" method="post" name="adduser" id="adduser" class="validate"<?php do_action('user_new_form_tag');?>>
        <input name="action" type="hidden" value="adduser" />
        <?php wp_nonce_field( 'add-user', '_wpnonce_add-user' ) ?>
        <?php
        // Load up the passed data, else set to a default.
        foreach ( array( 'user_login' => 'login', 'first_name' => 'firstname', 'last_name' => 'lastname',
                        'email' => 'email', 'url' => 'uri', 'role' => 'role', 'send_password' => 'send_password', 'noconfirmation' => 'ignore_pass' ) as $post_field => $var ) {
            $var = "new_user_$var";
            if( isset( $_POST['createuser'] ) ) {
                if ( ! isset($$var) )
                    $$var = isset( $_POST[$post_field] ) ? wp_unslash( $_POST[$post_field] ) : '';
            } else {
                $$var = false;
            }
        }

        ?>

                    foreach ( $editable_roles as $role => $details ) {
                        if( 'administrator' == $role )

                        $name = translate_user_role($details['name'] );
                        if ( $selected == $role ) // preselect specified role

                        else

                    echo $p . $r;

                    </select>
                </td>
            </tr>
        </table>
        <?php submit_button( __( 'Add New User '), 'primary', 'createuser', true, array( 'id' => 'createusersub' ) ); ?>
    </form>
    <?php
    }

The last thing to do is to handle the submit request, do error checking and then create user using wp_insert_user()

if($_POST['createuser']){
            //nonce verification for security
            check_admin_referer('add-user', '_wpnonce_add-user');

            $user_login     = $_POST['user_login'];
            $email          = $_POST['email'];
            $first_name     = $_POST['first_name'];
            $last_name      = $_POST['last_name'];
            $pass1          = $_POST['pass1'];
            $pass2          = $_POST['pass2'];
            $url            = $_POST['url'];
            $send_password  = $_POST['send_password'];
            $role           = $_POST['role'];

            //Handling errors
            if( empty($user_login) || empty($email) ){
                echo "Username or Email can't be empty";
            }elseif( !is_email($email) ){
                echo "Invalid email";
            }elseif( empty($pass1) ){
                echo "Password can't be empty";
            }elseif( $pass1 !== $pass2 ){
                echo "Password doesn't match";
            }else{
                //No errors. Create User.
                $userdata = array(
                    'user_login'    => $user_login,
                    'user_pass'     => $pass1,
                    'user_email'    => $email,
                    'user_url'      => $url,
                    'first_name'    => $first_name,
                    'last_name'     => $last_name,
                    'role'          => $role
                );
                $user_id = wp_insert_user( $userdata );
                if( !is_wp_error($user_id) ){
                    //User created.
                    echo "User created";
                }else{
                    //There was some error like duplicate email, username etc. Show the error
                    foreach( $user_id->errors as $name=>$errors ){
                        foreach( $errors as $error ){
                            echo $error;
                        }
                    }
                }
            }
        }

Then all you have to do is to initialize the class

$new_user = new create_user();

The whole code is posted below

<?php

        add_action('admin_menu', array( &$this, 'add_menu') );
    }

    public function add_menu(){
        //Creating top level menu as staff
        //Use add_submenu_page for adding additional submenu
        add_menu_page( 'Staff', 'staff', 'edit_users', __FILE__, array( &$this, 'show_staff_page' ) );
    }

    public function show_staff_page(){
        //Processing submitted data
        if($_POST['createuser']){
            //nonce verification for security
            check_admin_referer('add-user', '_wpnonce_add-user');

            $user_login     = $_POST['user_login'];
            $email          = $_POST['email'];
            $first_name     = $_POST['first_name'];
            $last_name      = $_POST['last_name'];
            $pass1          = $_POST['pass1'];
            $pass2          = $_POST['pass2'];
            $url            = $_POST['url'];
            $send_password  = $_POST['send_password'];
            $role           = $_POST['role'];

            //Handling errors
            if( empty($user_login) || empty($email) ){
                echo "Username or Email can't be empty";
            }elseif( !is_email($email) ){

            }elseif( $pass1 !== $pass2 ){

                );
                $user_id = wp_insert_user( $userdata );
                if( !is_wp_error($user_id) ){
                    //User created.
                    echo "User created";
                }else{
                    //There was some error like duplicate email, username etc. Show the error
                    foreach( $user_id->errors as $name=>$errors ){
                        foreach( $errors as $error ){

                        $name = translate_user_role($details['name'] );
                        if ( $selected == $role ) // preselect specified role

                            $r .= "\n\t<option value='" . esc_attr($role) . "'>$name</option>";

                    </select>
                </td>
            </tr>
        </table>
        <?php submit_button( __( 'Add New User '), 'primary', 'createuser', true, array( 'id' => 'createusersub' ) ); ?>
    </form>
    <?php
    }
}

$new_user = new create_user();

EDIT: I don't fully understand what you are trying to do. But it seems that you want to create user group. The staff that you are adding is list of users. They will be shown in all user list too. Wordpress by default doesn't have anything like user group. First you need to clear what you are trying to achieve with your code.

Wow, this is great! Thank you for the detailed explanation! I threw this into a blank page and it worked just fine on it's own. Now I'm having trouble integrating it into what I have set up. Code is too long so I'll post what I have in an answer question post.... –  jameslcarton Jan 6 at 21:26
    
@jameslcarton you can post your code in your question. This assumes that it's a separate plugin. Why don't you keep it like that? –  sakibmoon Jan 7 at 9:05
