WP Settings Page

Instructions

When creating admin settings pages for the plugin:

1. Register setting: Use register_setting() for storage
2. Add settings section: add_settings_section()
3. Add settings fields: add_settings_field()
4. Create options page: add_options_page()
5. Sanitize input: Use callback to clean data

Pattern

Copy// Register setting
register_setting('retrologin_options', 'retrologin_settings');

// Add section
add_settings_section('retrologin_general', 'General Settings', 'retrologin_section_cb', 'retrologin');

// Add field
add_settings_field('retrologin_color', 'Retro Color', 'retrologin_color_cb', 'retrologin', 'retrologin_general');

// Add menu page
add_options_page('RetroLogin Settings', 'RetroLogin', 'manage_options', 'retrologin', 'retrologin_options_page');

Options Page Structure

Copyfunction retrologin_options_page(): void {
    ?>
    <div class="wrap">
        <h1>RetroLogin Settings</h1>
        <form action="options.php" method="post">
            <?php
            settings_fields('retrologin_options');
            do_settings_sections('retrologin');
            submit_button();
            ?>
        </form>
    </div>
    <?php
}

Sanitization

Copyfunction retrologin_sanitize($input): array {
    $sanitized = [];
    if (isset($input['color'])) {
        $sanitized['color'] = sanitize_text_field($input['color']);
    }
    return $sanitized;
}

Guidelines

• Use single option array for related settings
• Always sanitize on save
• Use capabilities check: manage_options
• Store defaults on plugin activation
