I want to disable the srcset only when calling a specific thumbnail size (for example only when calling full image size). Here are two ideas (if I understand you correctly): Approach #1 Let’s check the size from the post_thumbnail_size filter. If it matches a corresponding size (e.g. full) then we make sure the $image_meta is … Read more
well if you are using WyPiekacz plugin; as you said for checking that featured image is uploaded, you can tweak it little bit to check that if there is featured image it is of minimum dimesions as you required. $has_thumbnail = false; if ( ( $post_id > 0 ) && function_exists( ‘has_post_thumbnail’ ) ) { … Read more
When an image is uploaded in WordPress, it is saved in its original size, and also as some resized copies in different sizes. In this way it becomes easy to use different sizes, of the same image, for different purposes. By default, WordPress creates 3 copies in 3 different sizes: ‘thumb’ ‘medium’ ‘large’ The size … Read more
Try the following. First, add this piece of code to the template: <?php $image_data = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), “thumbnail” ); ?> $image_data will now return an array containing the url, width, and height (function reference). To get the width, you might do this: <?php $image_width = $image_data[1]; ?> In your specific example, after adding … Read more
Not natively. You’d have to write some code to make it happen – there’s a nice pastebin function that provide the necessary code to do it. Edit (12/19/2011): Yep here’s how you can do this programmatically. Add the following two functions to your functions.php file and you should be good to go. The code has … Read more
When an image size is added either by WordPress(add_image_size), or by a plugin or your own custom code it gets added into the $_wp_additional_image_sizes global, i can’t find a similar function for pulling data from that global, but you could certainly just look inside the global to determine what width and height a registered image … Read more
Related: Filter to remove image dimension attributes? There’s a filter on post_thumbnail_html which receives as its argument the full html element representing the post thumbnail image before it’s echoed to the page. You can filter out the dimensions with a bit of regex: add_filter( ‘post_thumbnail_html’, ‘remove_thumbnail_dimensions’, 10, 3 ); function remove_thumbnail_dimensions( $html, $post_id, $post_image_id ) … Read more
Can’t this simply be done with media_sideload_image() ? Seems pretty simple. Only catch is if you aren’t on admin area, you must include some libraries from within WordPress includes: // only need these if performing outside of admin environment require_once(ABSPATH . ‘wp-admin/includes/media.php’); require_once(ABSPATH . ‘wp-admin/includes/file.php’); require_once(ABSPATH . ‘wp-admin/includes/image.php’); // example image $image=”http://example.com/logo.png”; // magic sideload … 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
My favorite way of handling this problem has been to use a little documented function I discovered on another stack post: media_sideload_image It works by fetching an image url to the WordPress upload dir and then associating the image to a post’s attachments. You can try it like so: // required libraries for media_sideload_image require_once(ABSPATH … Read more
