如何在Wordpress中提取不包括标题和徽标图像的帖子和页面图像？

Question

我已经尝试过此代码从媒体库中获取所有图像，并且我成功获取了所有图像的源URL，但是现在我想排除所有不需要的图像，例如徽标，标头图像等。

简而言之，我想提取所有附加到帖子和页面上的图像..

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标头图像，这对我来说是不需要的..如何排除它..我尝试使用附件大小，但是它一直都不是唯一的..看看它

Answer 1

从这一点上，您可能想要指定要过滤的内容。

    $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);

Answer 2

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中提取和/或对这些帖子中的所有图像进行映像。 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;

效率不是100％，但可以。
