You can directly get an attachment’s meta data if you have it’s ID. The alt data for an attachment is stored in _wp_attachment_image_alt. So, you can use: $alt = get_post_meta( $attachment->ID, ‘_wp_attachment_image_alt’, true); To get the caption of an image, you can use wp_get_attachment_metadata(). $metadata = wp_get_attachment_metadata( $id ); $caption = $metadata[‘image_meta’][‘caption’]; EDIT Based on … Read more
The caption is stored in the image data. The only way to achieve what you require is to use multiple copies of the image and change the image data on each image. To better understand image data go ahead and download an image to your desktop then right click it, go to properties then the … Read more
Adapted from this answer Add this code to your functions.php file: add_action( ‘after_setup_theme’, ‘wpse_74735_replace_wp_caption_shortcode’ ); /** * Replace the default caption shortcode handler. * * @return void */ function wpse_74735_replace_wp_caption_shortcode() { remove_shortcode( ‘caption’, ‘img_caption_shortcode’ ); remove_shortcode( ‘wp_caption’, ‘img_caption_shortcode’ ); add_shortcode( ‘caption’, ‘wpse_74735_caption_shortcode’ ); add_shortcode( ‘wp_caption’, ‘wpse_74735_caption_shortcode’ ); } /** * Add the new class to … Read more
This is/was a known bug that should be fixed in WP >= 4.4 See this ticket for details: https://core.trac.wordpress.org/ticket/28003
Adjust image caption within visal editor
If I understood correctly, you are trying to add, to every image embedded in a post gallery, a custom rel attribute and a title attribute based on the attachment caption. Instead of parsing the content, you can try to modify the anchor that wraps the images using the ‘wp_get_attachment_link’ filter. <?php function wpse221533_add_caption_title_to_content_gallery_image_attachments( $markup, $id, … Read more
Get the attachment ID and convert to a post. From there the caption is stored on the post object. $thumb_img = get_post( get_post_thumbnail_id() ); // Get post by ID echo $thumb_img->post_excerpt; // Display Caption echo $thumb_img->post_content; // Display Description In your loop it would look like: <?php if($gallery) : ?> <?php foreach($gallery as $key => … Read more
You can add to figcaption on your front-end. <?php if ( !empty( $images ) ) { foreach ( $images as $image ) { $image_post = get_post($image); $caption = $image_post->post_excerpt; echo ‘<li class=”animated fadeIn”>’, ‘<figure>’, wp_get_attachment_image( $image, ‘post-full-width’ ), ‘<figcaption>’, $caption, ‘</figcaption>’, ‘</figure>’, ‘</li>’; } } ?>
I had to generate a bunch of extra code because I don’t think you’ve posted it all. In this case I don’t have scripts to add galleries so I tested it by pulling gallery data inside the post to populate the meta box. Each caption text field is generated per image then updated on post … Read more
There is a hook inside the caption shortcode that will allow you to hijack the whole thing. Most of the following is copied from the Core img_caption_shortcode function. function nested_img_caption_shortcode($nada, $attr, $content = null) { extract( shortcode_atts( array( ‘id’ => ”, ‘align’ => ‘alignnone’, ‘width’ => ”, ‘caption’ => ” ), $attr, ‘caption’ ) ); … Read more
