This issue has been fixed with a filter in WordPress 4.5. If you want to preserve the exif data when resizing use add_filter (‘image_strip_meta’, false);
If you really want to use these classes the only way would be to extend both existing implementations Wp_Image_Editor_Imagick and Wp_Image_Editor_GD. Here’s an approach for the Wp_Image_Editor_GD: namespace WPSE98156; use Wp_Image_Editor_Gd, Wp_Error; class WatermarkImageEditor extends Wp_Image_Editor_Gd { /* * @param resource $stamp (A GD image resource) * * @return bool|WP_Error */ public function stamp_watermark( $stamp … Read more
I found a solution based on the code of this page: https://core.trac.wordpress.org/ticket/22180 All attachment files have a post status of ‘inherit’. So first you need to add “inherit” as one of the possible post status to search for. You can use the wp_link_query_args filter to do that. function my_wp_link_query_args( $query ) { if (is_admin()){ $query[‘post_status’] … Read more
added_post_meta seems like a good time to hook into a new image. Not only is the default meta already set but the function gives you the $post_id along with $meta_value which holds the attachment metadata. From there you can get all the fields and set the ones you want. add_action(‘added_post_meta’, ‘wpse_20151219_after_post_meta’, 10, 4); function wpse_20151219_after_post_meta($meta_id, … Read more
Thanks to Mike Jolley (Woocommerce plugin author) for the solution using: wp_get_attachment_image_src $prod_categories = get_terms( ‘product_cat’, array( ‘orderby’ => ‘name’, ‘order’ => ‘ASC’, ‘hide_empty’ => true )); foreach( $prod_categories as $prod_cat ) : $cat_thumb_id = get_woocommerce_term_meta( $prod_cat->term_id, ‘thumbnail_id’, true ); $shop_catalog_img = wp_get_attachment_image_src( $cat_thumb_id, ‘shop_catalog’ ); $term_link = get_term_link( $prod_cat, ‘product_cat’ );?> <a href=”https://wordpress.stackexchange.com/questions/200170/<?php echo … Read more
If I had to guess: because images are Attachments, and Attachments are a Post-Type. Thus, in order to edit an image, which is an attachment, which is a post, requires the edit_post capability. EDIT Don’t you have your capability mapping array keys/values reversed? e.g. you have ‘edit_posts’ => ‘edit_listings’. Shouldn’t it instead be ‘edit_listings’ => … Read more
i guess you are looking for this add_attachment and delete_attachment example: add_action(‘add_attachment’, ‘attachment_manipulation’); function attachment_manipulation($id) { if(wp_attachment_is_image($id)){ //do your own tasks } }
Thumbnails in WordPress can be generated by using wp_generate_attachment_metadata(), this function fires a filter after generating all the thumbnails wp_generate_attachment_metadata and the filter provides $metadata and $attachment_id to the hooked functions. You can hook your custom function to this filter. $metadata : Attachment metadata. What you need is $metadata[‘sizes’][‘<size-name>’], the <size-name> is the name of … Read more
Using birgire’s suggestions, I came up with the following solution that is working well with both the old pre-WP 4.x data and the newer posts that have been added under 5.0. // if there is a gallery block do this if (has_block(‘gallery’, $post->post_content)) { $post_blocks = parse_blocks($post->post_content); $ids = $post_blocks[0][attrs][ids]; } // if there is … Read more
