Display Thumbnails Description with Multiple Post Thumbnails - php

Question

I've added multiple featured images to my wordpress site using the multiple post thumbnail plugin. I'm trying to display them all underneath the content with their descriptions. I can do it for the main featured image no problem. I can display the rest of the featured images no problem, but whenever I try to add description by it's the page description not the image description.
This is how I added the main image and description.
<?php the_post_thumbnail( 'product-thumbnail' );
echo get_post(get_post_thumbnail_id())->post_content; ?>
The remaining images are added as such:
<?php MultiPostThumbnails::the_post_thumbnail(get_post_type(), 'secondary-
image', NULL, 'product-thumbnail');
?>
And so forth (third, fourth)..
Can somebody help with how to add the descriptions for the rest?

Answer 1

To display your post thumbnail with its caption, simply paste the following code inside the loop:
<?php the_post_thumbnail();
echo get_post(get_post_thumbnail_id())->post_excerpt; ?>
You can also display entire image description by adding this code inside the post loop:
<?php the_post_thumbnail();
echo get_post(get_post_thumbnail_id())->post_content; ?>
the above codes for single images if you use multiple images use this code below
<?php
$the_post_images = get_children( array(
'post_parent' => $post->ID,
'post_type' => 'attachment',
'post_mime_type'=> 'image'
) );
foreach ($the_post_images as $the_post_image) {
// SHOW FEATURED IMAGE TITLES
echo get_the_title( $the_post_image->ID );
//SHOW IMAGE DESCRIPTION OR CAPTIONS
echo apply_filters( 'get_the_excerpt', $the_post_image->post_excerpt );
}
?>

To get image, its caption in multiple post thumbnails,
`
echo $secondimgPath = MultiPostThumbnails::get_post_thumbnail_url( get_post_type(), 'second-featured-image', NULL);
echo $secondimgIdAttachment = abcd_get_attachment_id_by_url($secondimgPath);
$size = array( 854,395, 'bfi_thumb' => true, 'quality' => 100);
echo $secondLargeImage[0] = wp_get_attachment_image( $secondimgIdAttachment,$size );
echo get_post( $secondimgIdAttachment )->post_excerpt;
endif; ?>`
In functions.php, use the following -
function abcd_get_attachment_id_by_url( $url ) {
// Split the $url into two parts with the wp-content directory as the separator
$parsed_url = explode( parse_url( WP_CONTENT_URL, PHP_URL_PATH ), $url );
// Get the host of the current site and the host of the $url, ignoring www
$this_host = str_ireplace( 'www.', '', parse_url( home_url(), PHP_URL_HOST ) );
$file_host = str_ireplace( 'www.', '', parse_url( $url, PHP_URL_HOST ) );
// Return nothing if there aren't any $url parts or if the current host and $url host do not match
if ( ! isset( $parsed_url[1] ) || empty( $parsed_url[1] ) || ( $this_host != $file_host ) ) {
return;
}
// Now we're going to quickly search the DB for any attachment GUID with a partial path match
// Example: /uploads/2013/05/test-image.jpg
global $wpdb;
$attachment = $wpdb->get_col( $wpdb->prepare( "SELECT ID FROM {$wpdb->prefix}posts WHERE guid RLIKE %s;", $parsed_url[1] ) );
// Returns null if no attachment is found
return $attachment[0];
}
