Wordpress 3.5:包含图像的自己的画廊不起作用 [英] Wordpress 3.5: own gallery with included images doesn't work

问题描述

我刚刚更新到 Wordpress 3.5，但这会导致我的代码的一小部分崩溃:有一个 php 文件，它通过 AJAX 加载带有画廊的特定帖子.

I just updated to Wordpress 3.5, but this crashed a little part of my code: There is a php file, which loads a specific post with its gallery via AJAX.

代码如下:

<?php

// Include WordPress
define('WP_USE_THEMES', false);
require('../../../../wp-load.php');

$id = $_POST['id'];

// query post with this identifier
query_posts('meta_key=identifier&meta_value='.$id); 
if (have_posts()) :
while (have_posts()) : the_post();

    // add content
    $content = apply_filters('the_content', get_the_content()); 
    echo '<div class="content-inner">'.$content.'</div>';
endwhile;
endif;
?>

该帖子包含 [gallery] 短代码.我已经使用以下代码构建了自己的 Wordpress 画廊:

The post contains a [gallery] shortcode. I've build my own Wordpress gallery with this code:

remove_shortcode('gallery');
add_shortcode('gallery', 'parse_gallery_shortcode');

function parse_gallery_shortcode($atts) {

    global $post;

    extract(shortcode_atts(array(
        'orderby' => 'menu_order ASC, ID ASC',
        'id' => $post->ID,
        'itemtag' => 'dl',
        'icontag' => 'dt',
        'captiontag' => 'dd',
        'columns' => 3,
        'size' => 'full',
        'link' => 'file'
    ), $atts));

    $args = array(
        'post_type' => 'attachment',
        'post_parent' => $id,
        'numberposts' => -1,
        'orderby' => $orderby
        ); 

    $images = get_posts($args);
    print_r($images);
}

这适用于我网站上的所有其他画廊，但不适用于 ajax 加载的画廊.它已与 Wordpress 3.4 一起使用.

This works with all other galleries on my site, but not with the ajax-loaded ones. And it has worked with Wordpress 3.4.

Wordpress 3.5 中是否有我忽略的更改?

Are there changes in Wordpress 3.5 that I've overlooked?

推荐答案

我想通了:如果您使用已上传到媒体库的图像画廊，画廊简码看起来像 [gallery ids=1,2,3]，这意味着图片仅链接(而非附加)到图库，因此 post_type=attachment 不起作用.

I figured it out: If you use a gallery with images, which are already uploaded to the media library, the gallery shortcode looks like [gallery ids=1,2,3], what means, that images are only linked (and not attached) to the gallery, so post_type=attachment doesn't work.

现在我使用正则表达式来获取图像 ID:

Now i'm using regular expressions to get the image IDs:

$post_content = $post->post_content;
preg_match('/\[gallery.*ids=.(.*).\]/', $post_content, $ids);
$array_id = explode(",", $ids[1]);
