Wordpress中的更新選項自定義帖子類型選項頁面

Question

我已經創建了一個文件，該選項頁面添加了一個WP自定義帖子類型，該類型應該顯示幻燈片放映選項，並且在保存數據時遇到問題。基本上，當你點擊提交按鈕，我希望它更新選項。感謝您的幫助:)

這裏是我的代碼：

{

<?php 

    // Add Options in the database. 
    add_option('slider_width', 960); 
    add_option('slider_height', 350); 


    // Create options to display. 
    $prefix = 'slider'; 
    $options = array(
     array(
      'name' => 'Slider Width', 
      'desc' => 'Set the width of the slideshow in pixels.', 
      'id' => $prefix.'_width', 
      'type' => 'text' 
     ), 
     array(
      'name' => 'Slider Height', 
      'desc' => 'Set the height of the slideshow in pixels.', 
      'id' => $prefix.'_height', 
      'type' => 'text' 
     ), 
     array("type" => "close"), 
     array('type' => 'section'), 
     array("type" => "open") 

    ); // end $options 

    // Add options page to admin area 
    function slider_add_admin() { 
    global $prefix, $options; 


    if ($_GET['page'] == 'slider_options') { 
     if ('save' == $_REQUEST['action']) { 
      foreach ($options as $value) { 
      update_option($value['id'], $_REQUEST[ $value['id'] ]); } 
    foreach ($options as $value) { 
     if(isset($_REQUEST[ $value['id'] ])) { update_option($value['id'], $_REQUEST[ $value['id'] ] ); } else { delete_option($value['id']); } } 
     header("Location: edit.php?post_type=sliders&page=slider_options&saved=true"); 
    die; 
    } 
    else if('reset' == $_REQUEST['action']) { 
     foreach ($options as $value) { 
      delete_option($value['id']); } 
     header("Location: edit.php?post_type=sliders&page=slider_options&reset=true"); 
    die; 
    } 
    } 

    // Create Subpage 
    add_submenu_page('edit.php?post_type=sliders','Slider Page Options','Slider Options', 'edit_sliders', 'slider_options', slider_options); 

    } 

    function slider_options(){ 
     global $prefix, $options; 
     $i=0; 

     if ($_REQUEST['saved']) echo '<div id="message" class="updated fade"><p><strong>Slider settings saved.</strong></p></div>';

     <?php

     add_action('admin_menu', 'slider_add_admin');

這可能會對你有所幫助;我爲Dashboard創建選項頁面有點不同，但它允許我在表單中創建任何我想要的東西。我從functions.php中包含這個文件。例如，它可以節省單個輸入字段，但是您可以通過添加更多行來製作更多字段，例如：

register_setting（'example_options_settings-group'，'example_some_other_field'）;

然後在example_options_settings_page（）窗體中輸入相應的輸入。

<?php 
add_action('admin_menu', 'example_options'); 

function example_options() { 
    $icon_path = get_bloginfo('template_url').'/images/icon-plugin.png'; 
    add_menu_page('Options', 'Options', 'delete_others_pages', __FILE__, 'example_options_settings_page',$icon_path, 115); 
    add_action('admin_init', 'example_options_settings'); 
} 

function example_options_settings() { 
    register_setting('example_options_settings-group', 'example_contact_url'); 
} 

function example_options_settings_page() { ?> 

<div class="wrap theme-options"> 

<div class="icon32" id="icon-options-general"><br /></div> 

<h2>Theme Options</h2> 

<form method="post" class="theme-options-form" action="options.php"> 

     <?php settings_fields('example_options_settings-group'); ?> 

     <div class="postbox metabox-holder"> 
      <h3 class="hndle">Contact Info</h3> 
      <div class="inside"> 
       <div class="option-panel"> 
        <p><label for="example_contact_url">Enter Email Address</label></p> 
        <p> 
         <?php $example_contact_url = get_option('example_contact_url'); ?> 
         <input id="example_contact_url" name="example_contact_url" value="<?php echo $example_contact_url; ?>" style="width: 90%;" type="text" /> 
        </p> 
       </div> 
      </div> 
     </div> 

<input type="hidden" value="1" /> 
    <p class="submit"> 
     <input type="submit" class="button-primary" value="<?php _e('Save Changes') ?>" /> 
    </p> 
</form> 

</div> 

<?php } ?>
