I need to get the list of images added in a gallery. WordPress

  • SOLVED

I have a custom post type named “services” and there I have a wysiwyg field, created with the “advanced custom field” plugin.
In that field, the user will add a gallery with images.

What I need is to be able to get the images from that gallery to use it on different places.

For example, in my home I want a list of all my services, with 4 images of each service.

It would be great if I could get the src for the different sizes, so I can create my own gallery (i created additional image sizes)

I just create a custom template for you. I assumed you named your services post type "services". If you named something else change it in the code.

It actually query the service post type, extract image ids from the gallery shortcode, then displays the image.

This code actually displays only 4 images. If you want to increase the limit, then change the $max variable.

Also its compatible with all image sizes. To change the size just modify this line

<blockquote>$image = wp_get_attachment_image_src( $image_id, 'large', false, '' );</blockquote>

For example if you have a custom size added liike this

<blockquote>add_image_size( 'service-thumb', 300, 200 );</blockquote>

then change that line like this

<blockquote>$image = wp_get_attachment_image_src( $image_id, 'service-thumb', false, '' );</blockquote>

So here is the complete code.

create a file called services.php and paste the code in there.

<?php
/*
Template Name: Services
*/
get_header(); ?>

<?php
$services = new WP_Query(array( 'post_type' => 'services' ) );

if ($services->have_posts()) : while ($services->have_posts()) : $services->the_post();

remove_shortcode('gallery');

$gallery_content = get_field('gallery', $post->ID);

preg_match('/\[gallery.*ids=.(.*).\]/', $gallery_content, $ids);
$image_ids = explode(",", $ids[1]);

$count = 0;
$max = 4;
foreach($image_ids as $image_id) {
$count++;
if ($count > $max) {
break;
}
$image = wp_get_attachment_image_src( $image_id, 'large', false, '' );
echo '<div class="image">';
echo '<img src="'.$image[0].'" alt="">';
echo '</div>';
}
endwhile; endif;
wp_reset_query();
?>

<?php get_sidebar(); ?>
<?php get_footer(); ?>

Heads up:

Don't forget to change your ACF gallery field id in this line.

$gallery_content = get_field('gallery', $post->ID);

I assumed it was named "gallery"

Hi,

If you are using wordpress image upload function to create gallery, you can use the following code to display images

<?php
// WP_Query arguments
$args = array (
'post_type' => 'services',
'posts_per_page' => '-1',
);

// The Query
$query = new WP_Query( $args );

// The Loop
if ( $query->have_posts() ) {
while ( $query->have_posts() ) {
$query->the_post();

// For fetching images from your wysiwyg field
$image_gallery = get_post_meta( get_the_ID(), 'image_gallery', true ); // Replace with your wysiwyg field name
// check if the custom field has a value
if( ! empty( $image_gallery ) ) {
preg_match('/\[gallery.*ids=.(.*).\]/', $image_gallery, $ids);
$image_ids = explode(",", $ids[1]); // Get all image ids from short code
$images = array_slice($image_ids,0,3);
foreach($images as $image)
{
echo wp_get_attachment_image( $image, 'customimage' );
}
}

}
} else {
// no posts found
}

// Restore original Post Data
wp_reset_postdata();
?>

You can use the following code in function.php to add image size

add_image_size('custombig', 600, 400, TRUE);
add_image_size('customsmall', 300, 152, TRUE);
add_image_size('customimage', 64, 64, TRUE);

Let me know if you need any help in this.

Good Luck


Hariprasad Vijayan comments:

Above code only works if you are using [gallery] short code to display gallery. If you are using any other method or any other plugin, it won't work.

Please ask if you have any doubt.


gprego comments:

Hi Hariprasad,
That code also worked perfectly!!
I just added the "$count = 0;$max = 4;" from Giri's code to only show 4 images, and worked great.
Thanks a lot for your answer.

Check http://support.advancedcustomfields.com/forums/topic/is-this-the-correct-way-to-display-gallery-images/ - This maybe what you need.


Navjot Singh comments:

To get images of different sizes you can use

<img src="<?php echo $image['sizes']['thumbnail']; ?>" />

Just replace thumbnail with whatever custom size you have created.


Navjot Singh comments:

This code will go inside that loop which is shown in the above link.
