这是一个非常奇怪和严重的问题。转到我的管理区域中的“所有图像” （相当于所有帖子）显示内存耗尽错误和白屏。这是在将内存增加到非常高的数量之后。

我想我想知道为什么需要这么多内存来构建一个简单的列表？

我认为这一定是我的错误，编码。也许我在声明帖子类型时做错了什么？这个领域有哪些常见的“陷阱”？我不想只说“增加内存”，因为对于一个严重的问题来说，这似乎是一个弱小的工作。

add_filter( 'manage_edit-image_columns', 'symbiostock_image_manager_edit_columns' );
function symbiostock_image_manager_edit_columns( $columns )
{
    $columns = array(
         'cb' => '<input type="checkbox" />',
        'image_preview' => 'Preview',
        'date' => 'Uploaded',
        'title' => 'Image Name',
        'description' => 'Description',
        'exclusive' => 'Exclusive',
        'price_bloggee' => 'Bloggee',
        'price_small' => 'Small',
        'price_medium' => 'Medium',
        'price_large' => 'Large',
        'price_vector' => 'Vector',
        'cat' => 'Category',
        'tag' => 'Keywords' 
    );

    return $columns;
}

add_action( 'manage_image_posts_custom_column', 'symbiostock_image_manager_custom_columns' );
function symbiostock_image_manager_custom_columns( $column )
{
    global $post;

    $custom = get_post_custom();

    switch ( $column ) {

         case 'date':            

            break;      

        case 'image_preview':

            echo '<img class="admin_preview_pic" alt="Image Preview" src="' . $custom['symbiostock_minipic'][0] . '" />';

            break;

        case 'description':

            the_excerpt();

            break;

        case 'exclusive':

            echo $exclusive = ucwords(str_replace('_', ' ', $custom[ "exclusive" ][ 0 ]));

            break;

        case 'discount_percent':

            echo $discount_percent = $custom[ "discount_percent" ][ 0 ];

            break;

        case 'price_bloggee':

            echo $price_bloggee = $custom[ "price_bloggee" ][ 0 ];


            break;

        case 'price_small':

            echo $custom[ "price_small" ][ 0 ];

            break;

        case 'price_medium':

            echo $custom[ "price_medium" ][ 0 ];

            break;

        case 'price_large':

            echo $custom[ "price_large" ][ 0 ];

            break;

        case 'price_vector':

            echo $custom[ "price_vector" ][ 0 ];

            break;

        case 'cat':

            echo get_the_term_list( $post->ID, 'image-type', '', ', ', '' );

            break;

        case 'tag':

            echo get_the_term_list( $post->ID, 'image-tags', '', ', ', '' );

            break;

    } //$column    
}

也许我如何声明自定义帖子类型存在问题。这是代码以防万一：

register_taxonomy( 'image-tags', array(
     'image' 
), array(
     'hierarchical' => false,
     'rewrite' => true,
     'query_var' => true,
    'singular_label' => 'Image Keyword',
    'exclude_from_search' =>false,
    'hierarchical'            => false,
    'labels'                  => $labels,
    'show_ui'                 => true,
    'show_admin_column'       => true,

    'slug' => 'image-tag',               
    'labels' => array(
        'name' => _x( 'Image Keywords', 'taxonomy general name' ),
        'singular_name' => _x( 'Keywords', 'taxonomy singular name' ),
        'search_items' =>  __( 'Search Images' ),
        'all_items' => __( 'All Image Keywords' ),
        'edit_item' => __( 'Edit Image Keyword' ),
        'update_item' => __( 'Update Image Keyword' ),
        'add_new_item' => __( 'Add New Image Keyword' ),
        'new_item_name' => __( 'New Keyword Name' ),
        'menu_name' => __( 'Image Keywords' ),
        ),
    'rewrite' => array(
        'slug' => 'search-images', // This controls the base slug that will display before each term
        'with_front' => false, 
    ),
) );
