This is How to Add Optional User Registration Fields in WordPress with PHP
When it comes to user registration in WordPress, the default fields provided by the platform – username, email, and password – may not always be enough. Often, you'll want to collect additional information from your users, such as their website, profile description, or other custom data points.
Fortunately, WordPress provides a flexible way to handle this scenario through the use of the wp_create_user()
and wp_update_user()
functions, combined with the power of plugins like Advanced Custom Fields.
In this blog post, we'll walk you through the step-by-step process of adding optional user registration fields in WordPress using PHP.
Step 1: Create a New User Account
To get started, let's first create a new user account using the wp_create_user()
function. This function takes three arguments: the username, password, and email address.
$user_id = wp_create_user( 'login_name', 'password', 'user@example.com' );
If the user account is created successfully, the function will return the user's ID, which we'll need for the next step.
Step 2: Update the User's Additional Data
Once the user account is created, we can use the wp_update_user()
function to add additional data to the user's profile. This function takes an array of user data as an argument, where you can specify the fields you want to update.
$website = 'http://example.com';
$user_data = wp_update_user(
array(
'ID' => $user_id,
'user_url' => $website
)
);
if ( is_wp_error( $user_data ) ) {
// There was an error; possibly this user doesn't exist.
echo 'Error.';
} else {
// Success!
echo 'User profile updated.';
}
In this example, we're updating the user's website URL. You can add any additional fields you need, such as the user's nickname, description, or custom data.
Step 3: Handle Custom User Data with Advanced Custom Fields
While the wp_update_user()
function allows you to add additional data to the user's profile, it's limited to the built-in user data fields. If you need to store custom user data, you should consider using a plugin like Advanced Custom Fields (ACF).
ACF provides a powerful and flexible way to add custom fields to WordPress, including user profiles. Here's an example of how you can use ACF to add a "Company" field to the user registration form:
- Install and activate the Advanced Custom Fields plugin.
- Create a new custom field group in the ACF settings, and add a "Company" field to it.
- Assign the custom field group to the "User" field.
- Update the user registration form to include the new "Company" field.
Here's what the updated user registration form might look like:
<form method="post" action="<?php echo site_url('wp-login.php?action=register', 'login_post') ?>">
<p>
<label for="user_login"><?php _e('Username') ?><br />
<input type="text" name="user_login" id="user_login" class="input" value="<?php echo esc_attr(wp_unslash($_POST['user_login'])); ?>" size="20" autocapitalize="off" /></label>
</p>
<p>
<label for="user_email"><?php _e('Email') ?><br />
<input type="email" name="user_email" id="user_email" class="input" value="<?php echo esc_attr(wp_unslash($_POST['user_email'])); ?>" size="25" /></label>
</p>
<p>
<label for="company"><?php _e('Company') ?><br />
<input type="text" name="company" id="company" class="input" value="<?php echo esc_attr(wp_unslash($_POST['company'])); ?>" size="25" /></label>
</p>
<p class="submit">
<input type="submit" name="wp-submit" id="wp-submit" class="button button-primary" value="<?php esc_attr_e('Register') ?>" />
</p>
</form>
When the user submits the registration form, the wp_insert_user()
function will be called, and you can use the $_POST['company']
value to store the custom user data.
// Extra info to add
$website = "http://example.com";
$nickname = "Superman";
$description = "My description.";
$company = $_POST['company'];
$userdata = array(
'user_login' => 'login_name',
'user_url' => $website,
'nickname' => $nickname,
'description'=> $description,
'company' => $company,
'user_pass' => NULL // When creating an user, `user_pass` is expected.
);
$user_id = wp_insert_user( $userdata );
// On success.
if ( ! is_wp_error( $user_id ) ) {
echo "User created : ". $user_id;
}
In this example, we're using the wp_insert_user()
function to create the new user account and store the "Company" field value along with the other user data.
