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
Image captions in WordPress are actually shortcodes. Shortcodes are applied by the filter: $content = apply_filters(‘the_content’, $content); For example, WordPress creates the following code in your content when you enter an image caption: You need to still use apply_filters() in order to properly display content. (safe content display and all other shortcodes) If you don’t … Read more
Here’s what you can do. There’s a filter at the beginning of the shortcode execution function for the front end that will let you hijack the captions. Returning a non-empty value will stop execution of the shortcode, so if you just process the shortcode the way you want it to be processed and return that … Read more
Try this: $caption_info = array(); add_filter( ‘img_caption_shortcode’, ‘capture_caption’, 10, 3 ); function capture_caption( $blank = ”, $attr, $content ) { global $caption_info; $caption_info[] = array(‘attr’ => $attr, ‘content’ => $content ); return ‘ ‘; } It will save info from all captions into global $caption_info variable and suppress their display in content (space is returned … Read more
I don’t think you can do that, however you can implement this code in your functions file to at least allow for line breaks in single image captions Note: doesn’t work for gallery images (I am trying to find a way to make it work in galleries) /* ********************************************* Function to allow multi-line photo captions. … Read more
I wonder if this will work for you: add_action( ‘add_attachment’, function( $attachment_id ){ $a = get_post( $attachment_id ); if ( is_object( $a ) && ‘image’ === substr( $a->post_mime_type, 0, 5 ) ) wp_insert_attachment( array( ‘ID’ => $a->ID, ‘post_excerpt’ => $a->post_content ) ); }); or with less queries: add_action( ‘add_attachment’, function( $attachment_id ){ global $wpdb; if( … Read more
See my answer on question 3097 for a possible solution.
There’s really no documentation for it yet, but you’ll probably be able to do it hooking to the attachment_fields_to_save filter and inserting the default caption there. From the Codex: attachment_fields_to_save applied to fields associated with an attachment prior to saving them in the database. Called in the media_upload_form_handler function. Filter function arguments: an array of … Read more
