Using a filter for jpg_quality will hellp you to set your quality for uplaoded images. add_filter(‘jpeg_quality’, create_function(‘$n’, ‘return 70;’)); In most good implementations of Image Optimization you can find a various usae of ImageOptimization tools such as optimng/jpegtran etc, there a lot of plugins that help you to do that.
An attachment page is dedicated to a single attachment media item (image, video, audio etc.). You can change it’s behaviour by editing single-attachment.php. However this is not recommended. It is possible to create galleries and insert them in posts. Or install a plugin that displays custom posts as galleries of images.
No complete code, but I know you can stick it together. 🙂 Find all post IDs of unattached images (borrowed from wp-admin/upload.php): global $wpdb; $lost = $wpdb->get_col( ” SELECT ID FROM $wpdb->posts WHERE post_type=”attachment” AND post_parent > ‘0’ AND post_parent NOT IN ( SELECT ID FROM $wpdb->posts WHERE post_type NOT IN ( ‘attachment’, ‘” . … Read more
a) If you have reordered the images under the uploaded to this post in the media browser then they should have menu_order>0 and you can get that order with ‘orderby’ => ‘menu_order’, ‘order’ => ‘asc’ b) If you haven’t, then menu_order=0 for all these images and you will need to use ‘orderby’ => ‘ID’, ‘order’ … Read more
How do your users upload photos? You’re right about register_shutdown_function. It seems to work well in my code, though I only ever call my back-end via AJAX (I’ve also got file upload functionality), and so only need to account for this case. Here’s how I set it up in my plugin. Outside of the plugin … Read more
So I worked out what I was looking for. It seems that all images, when edited or uploaded, have something passed through wp_update_attachment_metadata and so I can hook into that to get the info I need.
get_the_content is a template tag and would only work reliably inside a Loop. That means that you should also be able to use the $post global instead. global $post; // may not be necessary unless you have scope issues // for example, this is inside a function $post_content = $post->post_content; preg_match(‘/\[gallery.*ids=.(.*).\]/’, $post_content, $ids); $array_id = … Read more
I don’t know the URL of an extension-less image to test this but I’d think that the server would have to pass a content-type header. If that is the case, you should be able to look at $get[‘headers’][‘content-type’], find out what kind of image it is, and tack the appropriate extension onto $image_file_name before sending … Read more
Your since83_pagination() function is assuming the main query– $wp_query— but you are needing to paginate something very different. You need to be paginating the results in $attachments which you are retrieving with get_children(). That was my guess as soon as I saw this question. You are going to need to rethink this. There are two … Read more
Changing the home and siteurl in your wp_options table is not enough unfortunately. You will still have your post content with your non-localhost URL (http://domain.com) causing your website to not display properly on your localhost. Once you’ve downloaded and imported your database to your localhost. Follow these steps: Go and download Interconnect IT’s Database Search … Read more
