This works: add_filter( ‘disable_captions’, create_function(‘$a’, ‘return true;’) ); function image_send_to_editor_2($html, $id, $caption, $title, $align, $url, $size, $alt) { $width=”auto”; if ( preg_match( ‘/width=”([0-9]+)/’, $html, $matches ) ) { $width = $matches[1] . ‘px’; } $output=”<div id=”attachment-” . $id . ‘” class=”wp-caption align’ . $align . ‘” style=”width: ‘ . $width . ‘;”>’; $output .= $html; … Read more
Ended up with the very low-tech, but functional, fix of adding<p> in place of an html paragraph tag. Worked like a charm.
As I posted in a comment, it turned out to be a glitch. I was using the text editor to edit the html of the page and decided to switch to the visual editor to check things. It turns out that the captions were properly rendered on the visual editor and when I published it … Read more
You’ll need to use the img_caption_shortcode filter to do this. Pretty certain the alignment of the image (floating left/right) is part of the caption so you’ll lose the ability to do that with this code. function imageOnly($deprecated, $attr, $content = null) { return do_shortcode( $content ); } add_filter( ‘img_caption_shortcode’, ‘imageOnly’, 10, 3 ); The do_shortcode … Read more
Use the shortcode handler img_caption_shortcode to render the HTML for you, though you do need to pass it a width (which we can easily get with wp_get_attachement_image_src: function wpse_138126_thumbnail_caption( $html, $post_id, $post_thumbnail_id, $size, $attr ) { if ( $post = get_post( $post_thumbnail_id ) ) { if ( $size = wp_get_attachment_image_src( $post->ID, $size ) ) $width … Read more
I solved it, the problem was a function I used to use and forgot about! add_filter( ‘post_thumbnail_html’, ‘remove_thumbnail_dimensions’, 10 ); add_filter( ‘image_send_to_editor’, ‘remove_thumbnail_dimensions’, 10 ); function remove_thumbnail_dimensions( $html ) { $html = preg_replace( ‘/(width|height)=\”\d*\”\s/’, “”, $html ); return $html; } I removed this function and everything is OK now.
For what it’s worth, this has been fixed in 3.4: http://core.trac.wordpress.org/ticket/18311
At this point in time I would just as soon not use the More Fields plugin at all, as there are native functions that can do everything you probably want with custom fields. There seems to be no good documentation afoot and the plugin site is obviously not being updated. Alternatively, try WPAlchemy. Quite easy … 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
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
