在Wordpress自定义文章类型选项页面中更新选项

Question

我创建了一个文件，该文件将选项页面添加到WP自定义帖子类型中，该类型本应显示幻灯片的选项，但我在保存数据时遇到了问题。基本上，当你点击提交按钮时，我希望它更新选项。感谢您的帮助：）

这是我的代码：

｛

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

        ?>
         <?php echo get_option('slider_width'); ?>
        <input type="hidden" name="action" value="save" />
        </form>
        <form method="post">
        <p class="submit">
        <input name="reset" type="submit" value="Reset" />
        <input type="hidden" name="action" value="reset" />
        </p>
        </form>
         </div> 

        <?php
        } // end slider_options
        add_action('admin_menu', 'slider_add_admin');
        ?>

}

这可能对您有所帮助；我为Dashboard创建选项页面有点不同，但它允许我在表单中创建任何我想要的东西。我从functions.php中包含了这个文件。例如，它保存了一个输入字段，但你可以通过添加更多的行来创建更多的字段，如下所示：

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

然后是example_options_settings_page（）表单中的相应输入。

<?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 } ?>
