我正在使用设置API为插件创建选项。我是否需要验证安全性的输入值（例如stripslashes等）？（我在大多数教程中都找不到这一部分）。下面是我正在做的：

<form method="post" action="options.php">
    <?php
        settings_fields( \'sandbox_theme_display_options\' );
        do_settings_sections( \'sandbox_theme_display_options\' );
        submit_button();            
    ?>
</form> 

function sandbox_initialize_theme_options() {
    add_settings_section(
        \'general_settings_section\',         
        __( \'Display Options\', \'sandbox\' ),
        \'sandbox_general_options_callback\',
        \'sandbox_theme_display_options\'
    );

    add_settings_field( 
        \'show_header\',
        __( \'Header\', \'sandbox\' ),
        \'sandbox_toggle_header_callback\',
        \'sandbox_theme_display_options\',
        \'general_settings_section\',
        array(
            __( \'Activate this setting to display the header.\', \'sandbox\' ),
        )
    );

register_setting(
        \'sandbox_theme_display_options\',
        \'sandbox_theme_display_options\'
    );

}
add_action( \'admin_init\', \'sandbox_initialize_theme_options\' );
