Ok, I’ve been playing with this for a little bit and have managed to change the output of the Gallery block, with the following caveats: The preview does not match the output. I think this is possible but appears to be a bit more involved. Certain classes and markup are required in the output for … Read more
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 ); } Source As sporkme explains later in the thread, this is dumped into your functions.php and can then … Read more
The add_image_size( $name, $width, $height, $crop ) function is graceful enough to handle multiple calls using the same $name. It simply overwrites the existing value: $_wp_additional_image_sizes[$name] = array( ‘width’ => absint( $width ), ‘height’ => absint( $height ), ‘crop’ => (bool) $crop ); So that means that all you need to do to override the … Read more
To remove the medium_large image size you can try to remove it with the intermediate_image_sizes filter: add_filter( ‘intermediate_image_sizes’, function( $sizes ) { return array_filter( $sizes, function( $val ) { return ‘medium_large’ !== $val; // Filter out ‘medium_large’ } ); } ); Not sure if you’re trying to remove all the intermediate sizes, but then you … Read more
There’s actually a great function that will do all three of those things for you: media_sideload_image( $url, $post_id, $description ); The first argument is the remote url of the image you want to download. The second argument is the post id of the post to which you want to attach the image. The third argument … Read more
This is another approach than the other answer that works when importing content with the importer and fixes the URLs once and for all. Again: This is not battle-tested but is the solution I settled on and it did work. I prefer this as it solves the issue once and for all and if it … Read more
You can get featured image URL and add it to your content manually, eg: <?php $image = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), ‘thumbnail’ ); if ($image) : ?> <img src=”https://wordpress.stackexchange.com/questions/29881/<?php echo $image[0]; ?>” alt=”” /> <?php endif; ?>
If you have the attachment id, you can use get_the_title() $attachment_title = get_the_title($attach_id) http://codex.wordpress.org/Function_Reference/get_the_title
Yes, it’s possible and pretty easy. This is the workflow I suggest: Put somewhere a UI to insert the URL of the featured image. Probably best choice is to use ‘admin_post_thumbnail_html’ filter hook Use ‘save_post’ action hook to save the URL (after security and validation routine) in a custom post meta Use ‘post_thumbnail_html’ filter hook … Read more
You can over write the default like this: add_image_size( ‘medium’, 200, 200, true );
