从[post_content]中的上述回复中，我找到了画廊短代码[画廊链接="file"列=“2”]。图像未显示。
是否有可能使用该简码从帖子内容中单独提取图像网址？
最佳答案
我使用下面的代码从图库短代码中提取图像，它正在工作。
<?php
global $post;
global $wp_query;
$currentPageCatId = get_cat_ID( "pagename" );
$NewsCatPostsArray = query_posts( 'cat='.$currentPageCatId);
$current_news_postId = $NewsCatPostsArray[$i]->ID;
$current_news_postUrl = get_permalink($current_news_postId);
$query_images_args = array('post_type' => 'attachment', 'post_mime_type' =>'image', 'post_status' => 'inherit', 'posts_per_page' => -1,'post_parent' => $current_news_postId);
$query_images = new WP_Query($query_images_args);
$images = array();
foreach ( $query_images->posts as $image) {
$images[]= $image->guid;
}
?>
