Create a New User via Form in Wordpress - wordpress

Question

I am trying to create a page-template on wordpress that allows me to create a new user through a form on the front end of the website. Basically I want it to be laid out like how it currently is on the wordpress admin page but I need to make it work on the frontend.
(Layout would look like this)wordpress admin create new user page
The part that I'm stuck now is, when the user presses submit how can I handle the data and add it into the wordpress db? (Using this https://codex.wordpress.org/Function_Reference/wp_create_user)
(Code so far...) -
<?php
/**
* Template Name: Create User
*/
get_header('user');
?>
<?php // Start the Loop.
while ( have_posts() ) : the_post(); ?>
<div id="left-content">
<?php //GET THEME HEADER CONTENT
theme_title(get_the_title()); ?>
<!-- START CONTENT -->
<div id="content">
<?php if (woffice_is_user_allowed()) { ?>
<!-- PHP Create User -->
<?php
function add_user_from_form() {
$user_login = $_POST['email'];
$first_name = $_POST['fName'];
$last_name = $_POST['lName'];
$user_email = $_POST['email'];
$user_pass = $_POST['pass'];
$display_name = "{$first_name} {$last_name}";
$role = $_POST['role'];
$info = array(
'user_login' => $user_login,
'user_pass' => $user_pass,
'user_email' => $user_email,
'display_name' => $display_name,
'first_name' => $first_name,
'last_name' => $last_name,
'role' => $role
);
$result = wp_insert_user( $info )
if ( is_wp_error( $result ) ) {
echo $result->get_error_message();
} else {
echo "Added user {$result}";
}
}
?>
<div class="box">
<form id="create-user-form" method="POST" action="<?php echo $_SERVER['PHP_SELF']?>">
<div class="row">
<div class="col-md-12">
<input value="" name="fName" id="fName" placeholder="First Name" required="" type="text">
<input value="" name="lName" id="lName" placeholder="Last Name" required="" type="text">
<input value="" name="email" id="email" placeholder="Email" required="" type="text">
<input value="" name="pass" id="password" placeholder="Password" required="" type="Password">
<select name="role">
<option value="author">Author</option>
<option value="contributor">Contributor</option>
</select>
<input name="submit" type="submit" class="btn-ser" value="Create New User" style="width:160px !important; padding-left:18px;">
</div>
</div>
</form>
</div>
<?php } else {
get_template_part( 'content', 'private' );
}
?>
</div>
</div><!-- END #content-container -->
<?php theme_scroll_top(); ?>
</div><!-- END #left-content -->
<?php // END THE LOOP
endwhile; ?>

If you want to insert the data in the WP db, you can use the WP database API.
You can include the global wpdb object in your code to post the form data in your database.
global $wpdb;
Then use the insert function to post the data in db.
<?php $wpdb->insert( $table, $data, $format ); ?>
Check this link for more details : https://codex.wordpress.org/Class_Reference/wpdb#INSERT_rowenter link description here
Create a function in your functions.php like below to handle your post data:
function my_theme_send_email() {
if ( isset( $_POST['email-submission'] ) && '1' == $_POST['email-submission'] ) {
// Send the email...
} // end if
} // end my_theme_send_email
add_action( 'init', 'my_theme_send_email' );
Refer this link as well they have explained very nicely : https://tommcfarlin.com/sending-data-post/

Users need a login name for database. Login can be anything. Users do not need to know it, because users can login with email address.
I would use wp_insert_user().
Example:
function add_user_from_form() {
$now = time(); // unique number
$c = chr( ($now % 26) + 65 ); // random letter
$user_login = $c . strval( $now ); // unique user name
$first_name = $_POST['fName'];
$last_name = $_POST['lName'];
$user_email = $_POST['email'];
$user_pass = $_POST['pass'];
$display_name = "{$first_name} {$last_name}";
/*
VALIDATE USER DATA BEFORE ADDING TO DATABASE
*/
$info = array('user_login' => $user_login,
'user_pass' => $user_pass,
'user_email' => $user_email,
'display_name' => $display_name,
'first_name' => $first_name,
'last_name' => $last_name);
$result = wp_insert_user( $info )
if ( is_wp_error( $result ) ) {
echo $result->get_error_message();
} else {
echo "Added user {$result}";
}
}
Simplest way use this on a page is to create a template with a different header and process form on the same page.
E.g. Copy page.php to create-user.php and add the template header.
Copy header.php to header-user.php. Replace get_header() with
get_header('user').
Edit action on form:
<form id="my-registration-form" method="post" action="<?php echo $_SERVER['PHP_SELF']">
Add my function to the top of header with:
if ( 'POST` == $_SERVER['REQUEST_METHOD'] ) {
add_user_from_form();
}
You do not need an action. You just need to process form.
This does not conform to best practice of using MVC pattern, but it is easy and it will work.
Hope this clarifies earlier answer.
