Get each images in body in Wordpress - php

Question

I have custom PHP scope in my Wordpress theme, like this:
foreach ($myprojects as $post){
setup_postdata( $post );
$output .= '<div class="col-xs-6 col-sm-3">';
$output .= '<div class="portfolio-item">';
if (has_post_thumbnail($post->ID)) {
$thumb = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'medium');
$large_image = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'full');
$content = get_post_field('post_content', $post_id);
$output .= '<img class="img-responsive" src="'.$thumb[0].'" title="" alt="">';
}else{
$output .= '<img class="img-responsive" src="images/work_1.jpg" title="" alt="">';
}
$post_id = get_the_title($post->ID);
$post_name = CFS()->get('project_name', '');
$output .= '<a class="overlay" rel="shadowbox" href="'.$large_image[0].'">';
$output .= '<p class="btn-preview">'.$post_id.'</p>';
$output .= '</a>';
$output .= '</div>';
$output .= '</div>';
$count++;
$index++;
}
Yes, it works fine. When I click a tag, open $large_image via prettyPhoto.
But this code for single image. I want to thumbnails stay same, but when click to link, open that multiple image via prettyPhoto. So, imported 2 images in post body and want to show these images.
In a nutshell, this code:
$large_image = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'full');
Must be like this:
$large_image = wp_get_attachment_image_src( $body($post->ID), 'full');
But I know, this is not correct code. Its pseudo.
How can I fix my problem? Thanks.

Change your lightbox solution to fancyBox, use data-fancybox-group and a bit of Wordpress/PHP knowledge... that's it!
foreach ($myprojects as $post){
setup_postdata( $post );
$output .= '<div class="col-xs-6 col-sm-3">';
$output .= '<div class="portfolio-item">';
if (has_post_thumbnail($post->ID)) {
$thumb = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'medium');
$large_image = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'full');
$content = get_post_field('post_content', $post_id);
$output .= '<img class="img-responsive" src="'.$thumb[0].'" title="" alt="">';
}else{
$output .= '<img class="img-responsive" src="images/work_1.jpg" title="" alt="">';
}
$post_id = get_the_title($post->ID);
$post_name = CFS()->get('project_name', '');
$output .= '<a class="overlay test fancybox" data-fancybox-group="'.$post->ID.'" href="'.$large_image[0].'">';
$output .= '<p class="btn-preview">'.$post_id.'</p>';
$output .= '</a>';
$output .= '</div>';
$output .= '</div>';
$attached_images = get_attached_media('image', $post->ID);
foreach($attached_images as $image){
$large_attached_image = wp_get_attachment_image_src($image->ID,'full');
if($large_image[0] != $large_attached_image[0]){
$output .= '<a class="overlay test fancybox" data-fancybox-group="'.$post->ID.'" style="display:none" href="'.$large_attached_image[0].'"></a>';
}
}
$count++;
$index++;
