Enregistrement de deux catégories à partir de deux listes déroulantes dans le formulaire de publication frontale

Alors, voici le deal:

J'ai deux listes déroulantes de catégories, la première pour les catégories parents et la seconde pour les catégories enfants. Ils forment une chaîne de sorte que lorsque vous sélectionnez la catégorie parent, la deuxième liste déroulante est renseignée avec ses catégories enfants. Voici le code dans le formulaire lui-même:

    <script type="text/javascript">
    $(function()
    {
    $('#main_cat').change(function()
    {
        var $mainCat=$('#main_cat').val();

        // call ajax
        $("#sub_cat").empty();
        $.ajax
        (
            {
                url:"<?php bloginfo('wpurl'); ?>/wp-admin/admin-ajax.php",     
                type:'POST',
                data:'action=my_special_ajax_call&main_catid=' + $mainCat,

                success:function(results)
                {
                    //  alert(results);
                    $("#sub_cat").removeAttr("disabled");       
                    $("#sub_cat").append(results);  
                }
            }
        );                                    
    });
    });
    </script>
    <fieldset class="site-url" class="fieldset-first">
    <?php wp_dropdown_categories('show_count=0&selected=-1&hierarchical=1&depth=1&hide_empty=0&exclude=1&show_option_none=Main Categories&name=main_cat&taxonomy=category');
    ?>
</fieldset>
<fieldset class="site-url" class="fieldset-first">
<select name="sub_cat" id="sub_cat" disabled="disabled"></select>
</fieldset>

Voici le code dans functions.php:

function implement_ajax() {
if(isset($_POST['main_catid']))
    {
    $categories=  get_categories('child_of='.$_POST['main_catid'].'&hide_empty=0'.'&taxonomy=category'.'&show_count=0');
      foreach ($categories as $cat) {
        $option .= '<option value="'.$cat->term_id.'">';
        $option .= $cat->cat_name;
        $option .= ' ('.$cat->category_count.')';
        $option .= '</option>';
      }
      echo '<option value="-1" selected="selected">Sub Categories</option>'.$option;
    die();
    } // end if
}
add_action('wp_ajax_my_special_ajax_call', 'implement_ajax');
add_action('wp_ajax_nopriv_my_special_ajax_call', 'implement_ajax');

Le problème est que lorsque vous enregistrez les valeurs comme ceci:

'post_category' =>   array($_POST['main_cat']),

Je ne ferai enregistrer que la catégorie parente pour le poste. Comment diable puis-je avoir le parent ET les catégories enfants à la fois sauvés? N'oubliez pas qu'une seule catégorie doit être sélectionnée dans chaque liste déroulante, pas de multiples.

À votre santé!

Pour résoudre ce problème, vous devrez utiliser plusieurs termes plutôt qu'un seul.

alors au lieu de:

$_POST['main_cat']

Utilisation:

array($_POST['main_cat'],$_POST['sub_cat'])

Vous ne devriez cependant pas avoir besoin de sauvegarder main_cat. Assigner sub_cat devrait impliquer que c'est aussi dans le terme parent de subcat
