だから、これは契約です:
2つのカテゴリドロップダウンがあります。1つは親カテゴリ用、もう1つは子カテゴリ用です。親カテゴリを選択すると、2番目のドロップダウンにその子カテゴリが表示されるように、それらはチェーンを形成します。これがフォーム自体のコードです。
<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");
$("#sub_cat").append(results);
}
}
);
});
});
</script>
<fieldset class="site-url" class="fieldset-first">
<?php wp_dropdown_categories('show_count=0&selected=-1&hierarchical=1&depth=1&hide_empty=0&exclude=1&show_option_none=Main Categories&name=main_cat&taxonomy=category');
?>
</fieldset>
<fieldset class="site-url" class="fieldset-first">
<select name="sub_cat" id="sub_cat" disabled="disabled"></select>
</fieldset>
これはfunctions.phpのコードです:
function implement_ajax() {
if(isset($_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');
問題は、このような値を保存するときです。
'post_category' => array($_POST['main_cat']),
親カテゴリのみが投稿用に保存されます。親カテゴリと子カテゴリの両方をどのように保存することができますか?各ドロップダウンから1つのカテゴリのみを選択し、倍数は選択しないようにしてください。
乾杯!
下記の全体POST投稿/保存コードで更新されました。

これを修正するには、単一の用語ではなく複数の用語を渡す必要があります。
その代わりに:
$_POST['main_cat']
つかいます:
array($_POST['main_cat'],$_POST['sub_cat'])
ただし、main_catを保存する必要はありません。 sub_catを割り当てることは、それがsubcatの親用語にもあることを意味するはずです
