This is all I can get from reading the source code for the wp_handle_upload function in wp-admin/includes/file.php. WordPress keeps the original uploaded file (usually) – see below… WordPress does apply JPEG compression to resized images when the source is a JPEG. The default JPEG compression level is 90. You can adjust the JPEG compression level … Read more
If I’m understanding correctly, each post has a filemaker, and each filemaker has only one photo? The structure is kind of unclear. Anyways, one way is top use media_sideload_image like below. However, media_sideload_image WON’T work with local files (a path on your filesystem), so you need to change your $file[‘url’] to be a valid URL … Read more
That is simple: <?php $categories = get_the_category($post->ID); if ($categories) { $category_ids = array(); foreach($categories as $individual_category) $category_ids[] = $individual_category->term_id; $args=array( ‘category__in’ => $category_ids, ‘post__not_in’ => array($post->ID), ‘showposts’=> 5, // Number of related posts that will be shown. ‘caller_get_posts’=> 1 ); $my_query = new wp_query($args); if( $my_query->have_posts() ) { echo ‘<h3>Related Posts</h3>’; echo ‘<ul>’; while ($my_query->have_posts()) … Read more
The task It’s not as easy, as it looks at a first glance. The main problem is, that you can define your own shortcode and simply override the default. Actually that’s what some themes are doing (blame you ThemeForest authors!). In this case, simply hooking into post_gallery won’t work in every case. Drawbacks for post_gallery … Read more
You can collect image attributes using “wp_get_attachment_metadata“, see below example as starting point function mytheme_post_thumbnail( $size=”post-thumbnail”, $attr=””, $post_id = null ) { if ( has_post_thumbnail( $post_id ) ) { $meta = wp_get_attachment_metadata( get_post_thumbnail_id( $post_id ) ); $args[‘width’] = $meta[‘sizes’][$size][‘width’]; $args[‘height’] = $meta[‘sizes’][$size][‘height’]; $args[‘alt’] = isset( $attr[‘alt’] ) ? $attr[‘alt’] : apply_filters( ‘post_title’, get_post( $post_id )->post_title … Read more
You can use taxonomies with the media library, you just need to either add a built-in taxonomy, or register a new one. For example, adding the built-in post tag taxonomy to attachments: function wpd_attachment_taxonomy() { register_taxonomy_for_object_type( ‘post_tag’, ‘attachment’ ); } add_action( ‘init’, ‘wpd_attachment_taxonomy’ ); You can then query for images with a specific tag: $args … Read more
Demo Plugin – Fixed Size Here’s one suggestion as a demo plugin (PHP 5.4+): <?php /* Plugin Name: Custom Playlist Thumb Size */ namespace WPSE238646\PlaylistThumbSize; add_shortcode( ‘playlist’, function( $atts = [], $content=”” ) { add_filter( ‘wp_get_attachment_image_src’, __NAMESPACE__ . ‘\\src’ , 10, 3 ); $out = wp_playlist_shortcode( $atts, $content ); remove_filter( ‘wp_get_attachment_image_src’, __NAMESPACE__ . ‘\\src’ ); … Read more
The wp_update_attachment_metadata filter fires every time you upload an image through media library (specifically every time wp_update_attachment_metadata function is being called). So when an svg file is uploaded we check if the file has the desired metadata, the width and height. If not, we generate the metadata as you did in your wp_get_attachment_image_src filter. Now … Read more
By default, wp-config.php might not have a closing tag ?> and this is acceptable and by design. The issue may arise from whitespace in some other .php file. In my case, I had whitespace after the closing tag of my functions.php file for my child theme. Once I removed that whitespace, the images are showing … Read more
Ah! The classic issue anyone that’s cared about their users’ experience has come to face. As per my experience, wp.media is the way to go. This is not my code, but it gets the job done. I’ve used it plenty. I’ll explain what it does, piece by piece: // Source: https://vedmant.com/using-wordpress-media-library-in-widgets-options/ jQuery(document).ready(function ($) { $(document).on(“click”, … Read more
