Email https://shortpixel.com/contact Twitter https://twitter.com/shortpixel Facebook https://www.facebook.com/ShortPixel LinkedIn https://www.linkedin.com/company/shortpixel Actions and Filters for Developers The ShortPixel Image Optimizer plugin calls the following actions and filters: do_action( 'shortpixel_image_optimised', $post_id ); upon successful optimization; do_action("shortpixel_before_restore_image", $post_id); before restoring an image from backup; do_action("shortpixel_after_restore_image", $post_id); after succesful restore; apply_filters('shortpixel_image_urls', $URLs, $post_id); filters the URLs that will be sent to optimisation, $URLs is a plain array; do_action('shortpixel/image/after_restore', $this, $this->id, $cleanRestore); This action can be used to cleanup the meta data from the database, regenerate thumbnails after restoring the main file, writing the updated meta data, etc. apply_filters('shortpixel/settings/image_sizes', $sizes); filters the array ($sizes) of image sizes that can be excluded from processing (displayed in the plugin Advanced settings); apply_filters('shortpixel/image/imageparamlist', $result, $this->id, $this); filters the list of parameters sent to the API so that resizing can be performed more granularly; apply_filters('shortpixel/api/request', $requestParameters, $item_id); filters the parameters sent to the optimization API (through $requestParameters), described in detail here: ShortPixel Reducer API; $item_id contains the ID of the Media Library item, or the ID of the Custom Media item (when used). In short, this filter can be used to alter any parameters sent to the API, depending on the needs. For example, you can set different resize parameters for different post types, different compression levels, remove EXIF or not, covert WebP/AVIF, and basically any other parameter that is sent to the API for a specific image (together with all its thumbnails). This filter enables the background ShortPixel processing in additional pages (see here the original list). Here’s an example of this filter that enables the processing on the Comments screen (to be placed in your functions.php file): add_filter('shortpixel/init/optimize_on_screens', function ($screens) { $screens[] = 'edit-comments'; return $screens; }); The edit-comments is the ID of the screen where you want to enable the processing. If you want to add multiple pages, here’s what the snippet looks like: add_filter('shortpixel/init/optimize_on_screens', function ($screens) { $screens = array('edit-comments', 'plugins', 'another-custom-post-type-page'); return $screens; }); add_filter('shortpixel/image/filecheck', function () { return true; }); This filter forces a file check for WebP/AVIF in case they were manually removed from disk. If you want to disable the automatic cache flush that is triggered after image optimization, you can use this filter: add_filter( 'shortpixel/external/flush_cache', function() { return false; } ); In order to define custom thumbnails to be picked up by the optimization you have two options, both comma separated defines: define('SHORTPIXEL_CUSTOM_THUMB_SUFFIXES', '_tl,_tr'); will handle custom thumbnails like image-100x100_tl.jpg; define('SHORTPIXEL_CUSTOM_THUMB_INFIXES', '-uae'); will handle custom thumbnails like image-uae-100×100.jpg; define('SHORTPIXEL_USE_DOUBLE_WEBP_EXTENSION', true); define('SHORTPIXEL_USE_DOUBLE_AVIF_EXTENSION', true); will tell the plugin to create double extensions for the WebP/AVIF image counterparts, for example, image.jpg.webp/image.jpg.avif for image.jpg; Enable the “Trusted mode” in case the file system has limitations and is very slow in responding to direct file operations by adding this constant: define('SHORTPIXEL_TRUSTED_MODE', true); This will simply skip file check operations and if the Media Library loads very slowly or freezes, you might want to try adding the constant above to your wp-config.php file. Disable the feedback survey when the plugin is deactivated: define('SHORTPIXEL_SKIP_FEEDBACK', true);
