the following should just show the caption: echo ‘<div class=”slideshow-content”><img src=”‘.wp_get_attachment_url($attachment->ID, ‘thumbnail’, false, false).'” /><div class=”captions”>’.apply_filters(‘the_excerpt’, $attachment->post_excerpt).'</div></div>’; (applying the excerpt filter adds the paragraph tag automatically)
Here is another possibility, it alters the image markup when you select an image to add to your content in the editor add_filter( ‘image_send_to_editor’, ‘remove_img_attribute’, 10, 8 ); function remove_img_attribute( $html, $id, $caption, $title, $align, $url, $size, $alt ) { $imagetpl=”<figure> <a href=”https://wordpress.stackexchange.com/questions/129666/%s” title=”https://wordpress.stackexchange.com/questions/129666/%s”><img src=”https://wordpress.stackexchange.com/questions/129666/%s” alt=”https://wordpress.stackexchange.com/questions/129666/%s” class=”img-responsive %s” /></a> %s </figure>”; $figcaption = (!empty($caption)) ? … Read more
It’s more a programming question, but try this: $post = get_post( get_post_thumbnail_id() ); if ( !isset( $post->post_title ) ) { echo ‘Sorry no title’; } else { echo $post->post_title; }
You can try this code to add the new attribute in the html code: $dom = new DOMDocument(); $dom->loadHTML($html); foreach ($dom->getElementsByTagName(“a’) as $item) { $item->setAttribute(‘data-caption’, ‘This is an anchor tag’); echo $dom->saveHTML(); exit; }
So I finally found a clue. The media article type stores the caption in post_excerpt, description in post_content. I’m not quite sure which field stores the alt text, but I’m quite happy with just storing the caption in post_excerpt.
Retrieve caption of image correct format is <?php $post_thumbnail_id = get_post_thumbnail_id( $post_id ); ?> <?php function wp_get_attachment( $attachment_id ) { $attachment = get_post( $attachment_id ); return array( ‘alt’ => get_post_meta( $attachment->ID, ‘_wp_attachment_image_alt’, true ), ‘caption’ => $attachment->post_excerpt, ‘description’ => $attachment->post_content, ‘href’ => get_permalink( $attachment->ID ), ‘src’ => $attachment->guid, ‘title’ => $attachment->post_title ); } $at= wp_get_attachment($post_thumbnail_id); … Read more
When you add an image with caption to the WP text editor, it should add a caption shortcode. Is that the case here? From there the output html should have some default classes like wp-caption. You can then style your caption by applying some CSS to these classes: /* The wrapper <div> for the caption … Read more
When you look at the last line img_caption_shortcode(), then you can see wp_kses() stripping non allowed HTML tags there. The wp_kses_hook() function does only wrap a filter: return apply_filters( ‘pre_kses’, $string, $allowed_html, $allowed_protocols ); which allows to hook in and alter the output before wp_kses_split() finally removes the HTML tag by using preg_replace_callback with _wp_kses_split_callback() … Read more
Gallery Image Captions – Hide/Show I just recalled this caption toggle question, when I was writing this answer, so let me rewrite it a little bit to work for this question. Let’s introduce the caption_toggle attribute for the native gallery shortcode, that takes a comma separated string of bool values. It’s possible to hide the … Read more
Something like this should work add_filter( ‘the_content’, ‘insert_featured_image’, 20 ); function insert_featured_image( $content ) { global $post; if ( has_post_thumbnail($post->ID) ) { $thumbnail_caption = get_the_post_thumbnail_caption( $post ); if ( $thumbnail_caption ) $caption = ‘<span class=”image-caption”>’ . $thumbnail_caption . ‘</span>’; else $caption = ”; // You can set this to whatever you want. $img = ‘<p>’ … Read more
