Question

我有一些特殊的post，来自category“图库”，我希望恢复所有attached media images。我遍历posts，然后我获取所有媒体，并将其保存在associative array中，但结果如下：

代码（仅限相关）

<?php $args=array(
    'category_name' => $gallery_category_slug,
    'post_type' => 'post',
    'post_status' => 'publish',
    'posts_per_page' => -1,
    'orderby'=> 'ID',
    'order' => 'asc',
);
$my_query = new WP_Query($args);
if( $my_query->have_posts() ) { ?>
<?php while ($my_query->have_posts()) : $my_query->the_post(); ?>
<?php echo get_the_ID(); ?> *ID of each post (OK)
<?php the_title(); ?> *Title of each post (Ok)
<?php 
    //Get Attached images from category (post)
    $args_att = array(
     'post_type' => 'attachment',
     'numberposts' => -1,
     'post_mime_type' => 'image',
     'post_status' => null,
     'post_parent' => get_the_ID() //Same ID always
    );
    $attachments = get_posts( $args_att );
    if ( $attachments ) {
        foreach ( $attachments as $attachment ) {
            $aux = wp_get_attachment_image_src($attachment->ID , 'full' );
            if($aux){
                $post_images[get_the_ID()][]= $aux[0];
            }
        }
    }
    ?>
<?php endwhile;?>

结果：

    Array ( [186] => Array ( [0] => http://testdomain/wp-content/uploads/2016/06/WINE.jpg [1] => http://testdomain/wp-content/uploads/2016/06/MASTERBEDROOM.jpg [2] => http://testdomain/wp-content/uploads/2016/06/POOL.jpg [3] => http://testdomain/wp-content/uploads/2016/06/TENNIS.png [4] => http://testdomain/wp-content/uploads/2016/06/ENTERTAINMENT.jpg [5] => http://testdomain/wp-content/uploads/2016/06/EXCERCISE.jpg [6] => http://testdomain/wp-content/uploads/2016/06/BEDROOMS.png [7] => http://testdomain/wp-content/uploads/2016/06/DSC_5854.jpg [8] => http://testdomain/wp-content/uploads/2016/06/DSC_5800.jpg ) )

期望的结果：

Array ( [186] => Array ( [0] => http://testdomain/wp-content/uploads/2016/06/WINE.jpg [1] => http://testdomain/wp-content/uploads/2016/06/MASTERBEDROOM.jpg [2] => http://testdomain/wp-content/uploads/2016/06/POOL.jpg ), [187] => Array ( [0] => http://testdomain/wp-content/uploads/2016/06/WINE.jpg [1] => http://testdomain/wp-content/uploads/2016/06/MASTERBEDROOM.jpg ), [188] => Array ( [0] => http://testdomain/wp-content/uploads/2016/06/WINE.jpg ))

我认为我弄乱了数组。

Answer 1

以下是我的理论：我认为问题出在get_the_ID()中的$post_images[get_the_ID()][]= $aux[0];，因为get_posts更改了$post使用的全局get_the_ID()对象。所以，我将帖子的ID放入变量中，然后在函数的其余部分使用它。

希望这有帮助。

<?php
$args=array(
    'category_name' => $gallery_category_slug,
    'post_type' => 'post',
    'post_status' => 'publish',
    'posts_per_page' => -1,
    'orderby'=> 'ID',
    'order' => 'asc',
);
$my_query = new WP_Query($args);
if( $my_query->have_posts() ) {
while ($my_query->have_posts()) : $my_query->the_post();
    $original_post_ID =  get_the_ID();
       the_title(); 

    //Get Attached images from category (post)
    $args_att = array(
     'post_type' => 'attachment',
     'numberposts' => -1,
     'post_mime_type' => 'image',
     'post_status' => null,
     'post_parent' => $original_post_ID //our new variable
    );
    $attachments = get_posts( $args_att );
    if ( $attachments ) {
        foreach ( $attachments as $attachment ) {
            $aux = wp_get_attachment_image_src($attachment->ID , 'full' );
            if($aux){
                $post_images[$original_post_ID][]= $aux[0];
            }
        }
    }
    endwhile;
?>

使用每个post wordpress的所有附件构造关联数组
