Pengaturan API WordPress, Menerapkan Tab Pada Halaman Menu Kustom

Saya telah mengikuti seri tutorial Pengaturan API WordPress dari orang ini:

http://wp.tutsplus.com/tutorials/theme-development/the-complete-guide-to-the-wordpress-settings-api-part-1/

Sejauh ini, saya sudah berhasil melakukan hal dasar. Sekarang, ketika menerapkan tab, saya menghadapi masalah.

Masalah 1: Tab tidak berfungsi. Semua bidang ditampilkan di kedua tab. Bagian 1, harus ditampilkan pada Tab Satu dan Bagian 2 pada Tab Dua.

Masalah 2: Opsi 2 tidak disimpan. Itu berfungsi dengan baik sebelum menerapkan tab.

Kode:

/* ----------------------------------------------------------------------------- */
/* Add Menu Page */

function add_my_menu() {
    add_menu_page (
        'Page Title', // page title

        'my-menu-slug',  // menu-slug
        'my_menu_page',   // function that will render its output
        get_template_directory_uri() . '/assets/ico/theme-option-menu-icon.png'   // link to the icon that will be displayed in the sidebar
        //$position,    // position of the menu option

Inilah cara saya melakukannya, waspadalah, posting sangat luas.

/* Add Menus
-----------------------------------------------------------------*/
add_action('admin_menu', 'ch_essentials_admin');
function ch_essentials_admin() {
    /* Base Menu */
    add_menu_page(
    'Essentials Theme',
    'Essentials Theme',
    'manage_options',
    'ch-essentials-options',
    'ch_essentials_index');
}

Sekarang untuk bidang pengaturan saya, bidang tambahan dihapus, sama seperti contoh.

Ini untuk 'Pengaturan Halaman Depan' dan 'Tab Halaman Depan'

add_action('admin_init', 'ch_essentials_options');
function ch_essentials_options() { 

/* Front Page Options Section */
add_settings_section( 
    'ch_essentials_front_page',
    'Essentials Front Page Options',
    'ch_essentials_front_page_callback',
    'ch_essentials_front_page_option'
);

add_settings_field(  
    'featured_post',                      
    'Featured Post',               
    'ch_essentials_featured_post_callback',   
    'ch_essentials_front_page_option',                     
    'ch_essentials_front_page'
);

Ini untuk opsi tajuk saya, yang merupakan tab 'opsi tajuk'

/* Header Options Section */
add_settings_section( 
    'ch_essentials_header',
    'Essentials Header Options',
    'ch_essentials_header_callback',
    'ch_essentials_header_option'
);

add_settings_field(  
    'header_type',                      
    'Header Type',               
    'ch_essentials_textbox_callback',   
    'ch_essentials_header_option',                     
    'ch_essentials_header',
    array(
        'header_type' 
    ) 
);

Pengaturan Pendaftaran

register_setting('ch_essentials_front_page_option', 'ch_essentials_front_page_option');
register_setting('ch_essentials_header_option', 'ch_essentials_header_option');

Semua ini dibungkus dalam satu fungsi, lalu dilakukan dengan admin_init

/* Options
-----------------------------------------------------------------*/
add_action('admin_init', 'ch_essentials_options');
function ch_essentials_options() { 
    /* Code Shown above */
}

Panggil Kembali:

/* Call Backs
-----------------------------------------------------------------*/
function ch_essentials_front_page_callback() { 
    echo '<p>Front Page Display Options:</p>'; 
}
function ch_essentials_header_callback() { 
    echo '<p>Header Display Options:</p>'; 
}
function ch_essentials_textbox_callback($args) { 

    $options = get_option('ch_essentials_header_option'); 

    echo '<input type="text" id="'  . $args[0] . '" name="ch_essentials_header_option['  . $args[0] . ']" value="' . $options[''  . $args[0] . ''] . '"></input>';

}
function ch_essentials_featured_post_callback() { 

    $options = get_option('ch_essentials_front_page_option'); 

    query_posts( $args );


    echo '<select id="featured_post" name="ch_essentials_front_page_option[featured_post]">';
    while ( have_posts() ) : the_post();

        $selected = selected($options[featured_post], get_the_id(), false);
        printf('<option value="%s" %s>%s</option>', get_the_id(), $selected, get_the_title());

    endwhile;
    echo '</select>';


}

Sekarang ini adalah bagian tampilan, dengan tab ..

Jika Anda memiliki bagian dan bidang pengaturan yang dilakukan persis seperti ini, maka Anda akan dapat melakukan tab dengan sempurna.

/* Display Page
-----------------------------------------------------------------*/
function ch_essentials_index() {
?>
    <div class="wrap">  
        <div id="icon-themes" class="icon32"></div>  
        <h2>Essentials Theme Options</h2>  
        <?php settings_errors(); ?>  

        <?php  
                $active_tab = isset( $_GET[ 'tab' ] ) ? $_GET[ 'tab' ] : 'front_page_options';  
        ?>  

        <h2 class="nav-tab-wrapper">  
            <a href="?page=ch-essentials-options&tab=front_page_options" class="nav-tab <?php echo $active_tab == 'front_page_options' ? 'nav-tab-active' : ''; ?>">Front Page Options</a>  
            <a href="?page=ch-essentials-options&tab=header_options" class="nav-tab <?php echo $active_tab == 'header_options' ? 'nav-tab-active' : ''; ?>">Header Options</a>  
        </h2>  


        <form method="post" action="options.php">  

            <?php 
            if( $active_tab == 'front_page_options' ) {  
                settings_fields( 'ch_essentials_front_page_option' );
                do_settings_sections( 'ch_essentials_front_page_option' ); 
            } else if( $active_tab == 'header_options' ) {
                settings_fields( 'ch_essentials_header_option' );
                do_settings_sections( 'ch_essentials_header_option' ); 

            }
            ?>             
            <?php submit_button(); ?>  
        </form> 

    </div> 
<?php
}

----- EDIT -----

dan saya perhatikan dalam postingan Anda bahwa Anda memiliki 'elseif' dan bukan 'else if' pada halaman tampilan Anda yang sebenarnya di bagian tab

<form method="post" action="options.php"> 

    <?php
        if( $active_tab == 'tab_one' ) {  

            settings_fields( 'setting-group-1' );
            do_settings_sections( 'my-menu-slug-1' );

        } elseif( $active_tab == 'tab_two' )  {

            settings_fields( 'setting-group-2' );
            do_settings_sections( 'my-menu-slug-1' );

        }
    ?> 

Ubah my-menu-slugke my-menu-slug-1danmy-menu-slug-2

Pengodean seperti ini berhasil untuk saya:
