I found the same issue here and the solution from there works. The solution is as simple as pasting this: $content_width = 2000;// Value higher than your new ‘large’ width in functions.php Explanation copied from there(user Chip Bennett): I believe your issue is that the value set for the global $content_width variable (which is 640px … Read more
You won’t be really able to tell which context the image is being used in in the wp_get_attachment_image_attributes filter, but you can pass custom attributes to wp_get_attachment_image() in the template directly with the 4th argument. Then you can use wp_get_attachment_image_url() and wp_get_attachment_image_srcset() to get the values for those attributes: $image = get_field(‘image’); $size=”gallery”; echo wp_get_attachment_image( … Read more
ZipArchive->addFile() method expects local path to file, while wp_get_attachment_url() returns URL. You need to build local path for file from URL or in other way.
Misspelling of thumbnail (thumnail) in the if statement. Also get_the_post_thumbnail does echo the thumbnail, but just returns the html. You need to echo it. Also, for checking if a post has a thumbnail, you can use has_post_thumbnail. if ( has_post_thumbnail($r->ID)) { echo get_the_post_thumbnail($r->ID, array(50,50)); }else{ echo ‘<img src=”https://wordpress.stackexchange.com/questions/44208/image_url”/>’; }
It’s because you’re not registering them as a media type. Every upload is a WordPress post of the attachment type. To start, it would be something like this: $file_name=”Some Name”; $file_path=”/path/to/uploads/2012/08/04/newfile.jpg”; $file_url=”http://url/to/uploads/2012/08/04/newfile.jpg”; $wp_filetype = wp_check_filetype($file, null); $attachment = array( ‘guid’ => $file_url, ‘post_mime_type’ => $wp_filetype[‘type’], ‘post_title’ => $file_name, ‘post_status’ => ‘inherit’, ‘post_date’ => date(‘Y-m-d H:i:s’) … Read more
You can use image_downsize filter and to catch when WordPress wants a downscaled image and not original, and actually a size what doesn’t exist. add_filter( ‘image_downsize’, ‘wpse_60890_retina_scale’, 10, 3 ); function wpse_60890_retina_scale( $value, $id, $size ) { if ( $size == ‘wpse_60890_retina_scaled’ ) { if ( !is_array( $imagedata = wp_get_attachment_metadata( $id ) ) ) return … Read more
Figured it out after a lot of trial and error and a lot of var_dumps. $image = wp_get_image_editor($file); if ( ! is_wp_error( $image ) ) { $image->resize( $width, $height, true ); $final_image = $image->save( $file ); } Then i can use the $final_image array to get what i need. It actually saved me a step … Read more
This is more of a general srcset and browser question, not a WordPress specific question. However, in general, you can’t predict what browsers will do with the srcset information. For your specific example, it appears that you failed to clear the cache completely between your reloads. Note the 304 response indicating that your browser already … Read more
Currently, WordPress core image handling/thumbnail creation does not perform zoom-crop. If you need an intermediate image size to be created explicitly, you will need to ensure that you upload an image with equal or larger dimensions as the intermediate image size.
There is a filter, wp_get_attachment_image_attributes, for the image attributes– a well designed one too. function alter_att_attributes_wpse_102079($attr) { $attr[‘data-src’] = $attr[‘src’]; return $attr; } add_filter( ‘wp_get_attachment_image_attributes’, ‘alter_att_attributes_wpse_102079’); That will add the data-src attribute. That looks like what you need. You could add more attributes, or alter the existing onese, if you need.
