我已经尝试过这个代码从媒体库中获取所有图像，我成功地获得了所有图像的源url，但现在我想排除所有不需要的图像，如徽标，头图像等…
总之，我想提取附加到帖子和页面的所有图像..
if(is_single() || is_page() || is_home() ){
global $post;
$query_images_args = array(
'post_type' => 'attachment', 'post_mime_type' =>'image', 'post_status' => 'inherit', 'posts_per_page' => -1,'numberposts' => 1
);
$query_images = new WP_Query( $query_images_args );
$images = array();
foreach ( $query_images->posts as $image) {
$images[]= wp_get_attachment_url( $image->ID );
}
echo "<pre>";
print_r($images);
echo "</pre>";
我的输出这里的第一个图像是一个头图像，这是我不想要的。如何排除它…我试过使用附件大小，但它不能一直是唯一的。看一看
Array

从这里开始，您可能需要指定您想要过滤的内容。
$images[]= wp_get_attachment_url( $image->ID );
}
$linkstoremove[] = $linksyouwanttoremove;
//remove unwanted images
$filtered_images = array_filter($images, $linkstoremove);
//set data sequence
$filtered_images = array_values($filtered_images);
print_r($filtered_images);
查询数据库并获取帖子，然后应用任何过滤器并从每个帖子和/或图像中提取这些帖子中的所有图像。例如:
$my_images = array();
$query_images_args = array(
'post_type' => 'attachment', 'post_mime_type' =>'image', 'post_status' => 'inherit', 'posts_per_page' => -1,'numberposts' => 1
);
$query_images = new WP_Query( $query_images_args );
while ( $query_images->have_posts() ) : $query_images->the_post();
$dcontent = apply_filters('the_content', get_the_content());
$dcontent = preg_replace("/'< *[img][^'>]*[.]*'>/i","",$dcontent,1);
if ( preg_match_all('/<img (.+?)>/', $dcontent, $matches) ) {
foreach ($matches[1] as $match) {
foreach ( wp_kses_hair($match, array('http')) as $attr)
$img[$attr['name']] = $attr['value'];
$my_images[] = $img['src'];
}
}
endwhile;
不是100%有效，但它有效。
