カスタム投稿タイプのカスタムフィールドに問題があります。なんらかの理由でフィールドが保存され、その後いくぶんランダムにクリアされます...私はそれがランダムではないと確信していますが、何が原因でこれが発生するのかはわかりません。これが私のカスタム投稿タイプのコードです：
// Custom Post Type: Strategic Giving
add_action('init', 'giving_register');
function giving_register() {
$labels = array(
'name' => _x('Invest Items', 'post type general name'),
'singular_name' => _x('Item', 'post type singular name'),
'add_new' => _x('Add New', 'giving item'),
'add_new_item' => __('Add New Item'),
'edit_item' => __('Edit Item'),
'new_item' => __('New Item'),
'view_item' => __('View Item'),
'search_items' => __('Search Items'),
'not_found' => __('Nothing found'),
'not_found_in_trash' => __('Nothing found in Trash'),
'parent_item_colon' => ''
);
$args = array(
'labels' => $labels,
'public' => true,
'publicly_queryable' => true,
'show_ui' => true,
'query_var' => true,
'menu_icon' => get_stylesheet_directory_uri() . '/images/cpt-giving.png',
'rewrite' => array( 'slug' => 'giving_items' ),
'capability_type' => 'post',
'hierarchical' => true,
'menu_position' => null,
'supports' => array('title','thumbnail','editor'),
'paged' => false,
);
register_post_type( 'givings' , $args );
}
register_post_type( 'givings' , $args );
add_action("admin_init", "giving_admin_init");
function giving_admin_init(){
add_meta_box("giving_info-meta", "Item Options", "giving_info", "givings", "side", "high");
}
function giving_info(){
global $post;
$custom = get_post_custom($post->ID);
$amount = $custom["amount"][0];
$monthly = $custom["monthly"][0];
$user_entered_value = $custom["user_entered_value"][0];
$item_name = $custom["item_name"][0];
$special = $custom["special"][0];
?>
<div style="text-align: right;">
<p>
<label for="amount"><strong>Amount:</strong></label>
<input style="width: 180px" type="text" name="amount" id="amount" value="<?php echo $amount; ?>" />
<em>Example: 30.00</em>
</p>
<p>
<label for="monthly"><strong>Monthly?</strong></label>
<?php if ($monthly == 'on') { ?>
<input type="checkbox" name="monthly" id="monthly" checked="checked" />
<?php } else { ?>
<input type="checkbox" name="monthly" id="monthly" />
<?php } ?>
</p>
<p>
<label for="special"><strong>Special Item?</strong></label>
<?php if ($special == 'on') { ?>
<input type="checkbox" name="special" id="special" checked="checked" />
<?php } else { ?>
<input type="checkbox" name="special" id="special" />
<?php } ?>
</p>
<p>
<label for="user_entered_value"><strong>Allow Giver To Enter Custom Value?</strong></label>
<?php if ($user_entered_value == 'on') { ?>
<input type="checkbox" name="user_entered_value" id="user_entered_value" checked="checked" />
<?php } else { ?>
<input type="checkbox" name="user_entered_value" id="user_entered_value" />
<?php } ?>
</p>
<p>
<label for="item_name"><strong>Item Name:</strong></label>
<input style="width: 180px" type="text" name="item_name" id="item_name" value="<?php echo $item_name; ?>" /><br />
If item is a <em>per item</em> then enter the name of the singular item. <em>Example: Chair - which will be displayed as "30.00 per Chair"</em>
</p>
<p style="text-align: left;">
Strategic Giving photo must be horizontal and uploaded/set as the <strong>Featured Image</strong> (see below).
<em>Do not add photo to content area.</em>

}更新：それで私はより多くの研究を行い、それを理解しました。自動保存（別名リビジョン）- ポストメタデータ自体が削除されます
グローバルではなく、単一の投稿タイプの自動保存をオフにすることはできますか？
revisionsにsupports、配列、自動保存して、あなたの「Givings」ポストタイプのために無効にする必要があります
