WordPress Settings API, Implémentation des onglets sur la page de menu personnalisée
J'ai suivi la série de tutoriels API WordPress Settings de ce type:
Jusqu'ici, j'ai réussi à faire la chose de base. Maintenant, lors de la mise en œuvre de l'onglet, je suis confronté à un problème.
Problème 1: Les onglets ne fonctionnent pas. Tous les champs sont affichés sur les deux onglets. La section 1 doit être affichée sur l'onglet 1 et la section 2 sur l'onglet 2.
Problème 2: l'option 2 n'est pas en cours de sauvegarde. Cela fonctionnait bien avant de mettre en place des onglets.
Code:

add_menu_page (
'Page Title', // page title
'Menu Title', // menu title

'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
);

Voici comment je le fais, méfiez-vous, le post est vaste.
/* 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');
}
Maintenant, pour mes champs de paramètres, les champs supplémentaires supprimés, juste à titre d'exemple.
Ceci est pour 'Paramètres de la page d'accueil' et 'Onglet de la page d'accueil'
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'
);
Ceci est pour mes options d'en-tête, qui est l'onglet "options d'en-tête"
/* 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'
)
);
Enregistrer les paramètres
register_setting('ch_essentials_front_page_option', 'ch_essentials_front_page_option');
register_setting('ch_essentials_header_option', 'ch_essentials_header_option');
Tous ces éléments sont encapsulés dans une fonction, puis exécutés avec un admin_init
/* Options
-----------------------------------------------------------------*/
add_action('admin_init', 'ch_essentials_options');
function ch_essentials_options() {
/* Code Shown above */
}
Rappels:
/* 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>';
}
Il s’agit maintenant de la partie affichage, avec les onglets ..
Si vos sections et paramètres de paramètres sont exactement identiques à ceux-ci, vous pourrez alors faire les onglets sans faille.
/* Display Page
