在wordpress中構建一個帶有複選框選項的插件

Question

我想用一些複選框來構建一個小部件，但是我不知道如何保存值。 有沒有一種方法來保存它們，我差不多在完成我的小部件的最後，謝謝。 這部分我的代碼：

function update($new_instance, $old_instance){ 

     $instance = $old_instance; 
     $instance['title'] = strip_tags($new_instance['title']); // new_instance es el titulo que ingresa el usuario 
     $urlsprite = strip_tags($new_instance['urlsprite']); 
     $urlfacebook = strip_tags($new_instance['urlfacebook']);   
     $urltwitter = strip_tags($new_instance['urltwitter']); 
     $urlpicassa = strip_tags($new_instance['urlpicassa']);   
     $urlyoutube = strip_tags($new_instance['urlyoutube']); 
     $urlrss = strip_tags($new_instance['urlrss']);    
     $chkfacebook = $new_instance['chkfacebook']; 
     $chktwitter = $new_instance['chktwitter']; 
     $chkpicassa = $new_instance['chkpicassa']; 
     $chkyoutube = $new_instance['chkyoutube']; 
     $chkrss = $new_instance['chkrss']; 

     return $instance; 

    } 

    function widget($args, $instance){   
    extract($args); 

     <a id="facebook" target="_blank" href="<?php echo $instance['urlfacebook'] ?>"></a> 
     <a id="twitter" target="_blank" href="<?php echo $instance['urltwitter'] ?>"></a> 
     <a id="picassa" target="_blank" href="<?php echo $instance['urlpicassa'] ?>"></a> 
     <a id="youtube" target="_blank" href="<?php echo $instance['urlyoutube'] ?>"></a> 
     <a id="rss" target="_blank" href="<?php echo $instance['urlrss'] ?>"></a> 

    <?php  
    }

這會幫助你。保存wordpress選項的基本示例。

<?php 
// create custom plugin settings menu 
add_action('admin_menu', 'baw_create_menu'); 

function baw_create_menu() { 

    //create new top-level menu 
    add_menu_page('BAW Plugin Settings', 'BAW Settings', 'administrator', __FILE__, 'baw_settings_page',plugins_url('/images/icon.png', __FILE__)); 

    //call register settings function 
    add_action('admin_init', 'register_mysettings'); 
} 


function register_mysettings() { 
    //register our settings 
    register_setting('baw-settings-group', 'new_option_name'); 
    register_setting('baw-settings-group', 'some_other_option'); 
    register_setting('baw-settings-group', 'option_etc'); 
} 

function baw_settings_page() { 
?> 
<div class="wrap"> 
<h2>Your Plugin Name</h2> 

<form method="post" action="options.php"> 
    <?php settings_fields('baw-settings-group'); ?> 
    <?php do_settings_sections('baw-settings-group'); ?> 
    <table class="form-table"> 
     <tr valign="top"> 
     <th scope="row">New Option Name</th> 
     <td><input type="text" name="new_option_name" value="<?php echo get_option('new_option_name'); ?>" /></td> 
     </tr> 

     <tr valign="top"> 
     <th scope="row">Some Other Option</th> 
     <td><input type="text" name="some_other_option" value="<?php echo get_option('some_other_option'); ?>" /></td> 
     </tr> 

     <tr valign="top"> 
     <th scope="row">Options, Etc.</th> 
     <td><input type="text" name="option_etc" value="<?php echo get_option('option_etc'); ?>" /></td> 
     </tr> 
    </table> 

    <?php submit_button(); ?> 

</form> 
</div> 
<?php } ?>
