How to add custom field in User form on Add / Edit.

In wordpress create custom field in user form by using ACF (Advanced Custom Field) plugin and also by using custom php code without using any plugin.

I will let you know step by step this process, First know how to do this with ACF Plugin.

1. Open your wordpress admin panel.

2. Install ACF (Advanced Custom Field) Plugin.

3. As per below image click on the Add new of Custom Field.

Above process is done using ACF Plugin. Now let you know step by step how to do the same using custom php code in functions.php of theme.

1. First of all call below hooks with add_action function.

add_action('show_user_profile', 'isExternalUser');
add_action('edit_user_profile', 'isExternalUser');
add_action('user_new_form', 'isExternalUser');

2. Now create the isExternalUser hook function.

function isExternalUser($user) {

    $checked = esc_attr(get_the_author_meta('is_external_user', $user->ID)) == 1 ? ' checked ' : ' ';

    echo '<table class="form-table">
                <th><label for="columnist">Is External User</label></th>
                    <input' . $checked . 'type="checkbox" name="is_external_user" id="is_external_user" value="1" class="checkbox double" />
                    <span class="description">Check if user is External.</span>

3. Again call below hooks with add_action function.

add_action('personal_options_update', 'update_user_external');
add_action('edit_user_profile_update', 'update_user_external');
add_action('user_register', 'update_user_external');

4. Now create update_user_external hook function.

function update_user_external($user_id) {

    if (!current_user_can('edit_user', $user_id)) {
        return false;

    $columnistValue = 0;
    if (isset($_POST['is_external_user'])) {
        $columnistValue = 1;

    update_usermeta($user_id, 'is_external_user', esc_attr($columnistValue));

Now your custom field with custom php code is created. You can check in your add/edit user form. Also look into the below image which I have shared.
