Créer et sauvegarder plusieurs méta-boîtes

J'ai créé un type de message personnalisé et plusieurs métaboxes qui doivent être enregistrés. J'ai une fonction qui enregistre une métabox, mais je ne vois pas comment réutiliser cette fonction pour enregistrer toutes les métaboxes.

add_action ("add_meta_boxes", "add_dedications_jh");

function add_dedications_jh() {
     add_meta_box('jh_dedicationDate', 'Enter Date', 'jh_dedicationDate', 'jh_dedications', 'side', 'default');
     add_meta_box('jh_dedicationName', 'Enter Name', 'jh_dedicationName', 'jh_dedications', 'normal', 'default');
     add_meta_box('jh_dedicationOccasion', 'Enter Occasion', 'jh_dedicationOccasion', 'jh_dedications', 'normal', 'default');
}

function jh_dedicationDate($object, $box) {
    wp_nonce_field( basename( __FILE__ ), 'dedicationDate_nonce' ); 
    ?>
    <input type="text" name="dedicationDate" value="<?php echo esc_attr( get_post_meta( $object->ID, 'dedicationDate', true) ); ?>" />
    <?php 
}

function jh_dedicationName ($object, $box) {
    wp_nonce_field( basename( __FILE__ ), 'dedicationName_nonce' ); 
    ?>
    <input type="text" size="60" name="dedicationName" value="<?php echo esc_attr( get_post_meta( $object->ID, 'dedicationName', true) ); ?>" /> 
    <?php
}

function jh_dedicationOccasion ($object, $box) {
    wp_nonce_field( basename( __FILE__ ), 'dedicationOccasion_nonce' ); 
    ?>
    <input type="text" size="60" name="jh_dedicationOccasion" value="<?php echo esc_attr( get_post_meta( $object->ID, 'dedicationOccasion', true) ); ?>" /> 
    <?php
}

add_action('save_post', 'jh_save_dedication', 10, 2);

function jh_save_dedication($post_id, $post) {
    /* Verify the nonce before proceeding. */
    if ( !isset( $_POST["dedicationDate_nonce"] ) || !wp_verify_nonce( $_POST["dedicationDate_nonce"], basename( __FILE__ ) ) )
        return $post_id;
    if ( !isset( $_POST["dedicationName_nonce"] ) || !wp_verify_nonce( $_POST["dedicationName_nonce"], basename( __FILE__ ) ) )
        return $post_id;
    if ( !isset( $_POST["dedicationOccasion_nonce"] ) || !wp_verify_nonce( $_POST["dedicationOccasion_nonce"], basename( __FILE__ ) ) )
        return $post_id;

    /* Get the post type object. */
    $post_type = get_post_type_object( $post->post_type );
    /* Check if the current user has permission to edit the post. */
    if ( !current_user_can( $post_type->cap->edit_post, $post_id ) )
        return $post_id;

    /* Get the posted data and sanitize it for use as an HTML class. */
    $new_meta_value = ( isset( $_POST['dedicationDate'] ) ? sanitize_html_class( $_POST['dedicationDate'] ) : '' );
    /* Get the meta key. */
    $meta_key = 'dedicationDate';
    /* Get the meta value of the custom field key. */
    $meta_value = get_post_meta( $post_id, $meta_key, true );
    /* If a new meta value was added and there was no previous value, add it. */
    if ( $new_meta_value && '' == $meta_value )
        add_post_meta( $post_id, $meta_key, $new_meta_value, true );
    /* If the new meta value does not match the old value, update it. */
    elseif ( $new_meta_value && $new_meta_value != $meta_value )
        update_post_meta( $post_id, $meta_key, $new_meta_value );
    /* If there is no new meta value but an old value exists, delete it. */
    elseif ( '' == $new_meta_value && $meta_value )
        delete_post_meta( $post_id, $meta_key, $meta_value );
}

Vous devez répéter les 9 dernières lignes de votre code pour les 2 autres champs nonce. Considérons la fonction suivante

function wp64123_sanitize_save_meta($nonce_field){

    /* Get the posted data and sanitize it for use as an HTML class. */
    $new_meta_value = ( isset( $_POST[$nonce_field] ) ? sanitize_html_class( $_POST[$nonce_field] ) : '' );

    /* Get the meta key. */
    $meta_key = $nonce_field;

    /* Get the meta value of the custom field key. */
    $meta_value = get_post_meta( $post_id, $meta_key, true );

        /* If a new meta value was added and there was no previous value, add it. */
    if ( $new_meta_value && '' == $meta_value )
        add_post_meta( $post_id, $meta_key, $new_meta_value, true );
        /* If the new meta value does not match the old value, update it. */
    elseif ( $new_meta_value && $new_meta_value != $meta_value )
        update_post_meta( $post_id, $meta_key, $new_meta_value );
        /* If there is no new meta value but an old value exists, delete it. */
    elseif ( '' == $new_meta_value && $meta_value )
        delete_post_meta( $post_id, $meta_key, $meta_value );      
}

Vous devez maintenant appeler la fonction ci-dessus pour chaque champ nonce.

wp64123_sanitize_save_meta("dedicationDate");
wp64123_sanitize_save_meta("dedicationName");
wp64123_sanitize_save_meta("dedicationOccassion");

Si vous soumettez et traitez le formulaire dans la zone d'administration WP, vous pouvez utiliser check_admin_referer() au lieu de wp_verify_nonce().

if ( !empty($_POST) && check_admin_referer('name_of_my_action','name_of_nonce_field') )
{
    // process form data
}
