默认选项值不自动工作

Question

嗨，wp 插件开发专家，我需要帮助。我已经应用了以下代码但没有使用默认值并且在单击保存按钮后没有显示更新的通知。当我将所有值都放在仪表板的选项页面中时，一切正常。但没有显示所有更新的通知。请帮助我。

<?php 
function hkhk_options() {
add_menu_page('Scrol Line Admin Settings', 'hk Settings','manage_options',
'hk_settings', 'hk_admin_options');
}
add_action('admin_menu', 'hkhk_options');


function hk_defaults()
{
$hk_options = array(
    'back_color' => '#ccc',
);

}
if ( is_admin() ) :

function hk_register_settings () {
register_setting('hkhk_options', 'hk_options', 'hk_validate_options');
}
add_action('admin_init', 'hk_register_settings');

function hk_admin_options() {
global $hk_options;

if ( ! isset( $_REQUEST['updated'] ) )
$_REQUEST['updated'] = false; 
?>
    <div class="wrap">
        <h2>Select Scrol Line Option</h2>
        <?php if ( false !== $_REQUEST['updated'] ) : ?>
<div class="update fade"><p><strong><?php _e( 'Options saved' ); ?></strong></p></div>
<?php endif; // If the form has just been submitted, this shows the notification ?>


        <form method="post" action="options.php">
        <?php $settings=get_option ( 'hk_options', $hk_options ); ?>
        <?php settings_fields('hkhk_options'); ?>
        <table class="form-table">
            <tr valign="top">
                <th scope="row"><label for="back_color"> Back Color </label></th>
                <td>
                    <input id="back_color" type="text" name="hk_options[back_color]" value="<?php esc_attr_e($settings['back_color']); ?>" class="wp-picker-container" /><p class="description"> Choose any color from here for background color. </p>
                </td>
            </tr>
        </table>
        <p class="submit"><input type="submit" class="button-primary" value="Save Options" /> </p>
        </form>
    </div>
<?php
}
function hk_validate_options( $input ){
   global $hk_options;
   $settings = get_option( 'hk_options', $hk_options );
     $input['back_color'] = wp_filter_post_kses( $input['back_color'] );

    return $input;
}
endif;
function scrol_line_active() {?>
<?php global $hk_options; $hk_settings = get_option ( 'hk_options', $hk_options ); ?>

<script type="text/javascript">
 jQuery(document).ready(function($) {
    jQuery("body") .hk({
        backColor: "<?php echo $hk_settings['back_color']; ?>",

    });
});
</script>
<?php
}
add_action ('wp_head', 'scrol_line_active');
?>

Answer 1

您正在检查错误的 REQUEST 参数。您需要检查 $_REQUEST['settings-updated'].
提交选项页面时，新 URL 类似于 /wp-admin/admin.php?page=hk_settings&settings-updated=true。

希望对您有所帮助。
