I would like to automatically set the alternative text to be the same as the title of a post when image is uploaded. The attachment’s image alternative text is stored in the post meta table under the _wp_attachment_image_alt meta key. In media_handle_upload() and media_handle_sideload() we have: $id = wp_insert_attachment($attachment, $file, $post_id); if ( !is_wp_error($id) ) … Read more
WordPress wp_is_mobile() can be the function that you’re looking for. // Use the build-in function if WP if(wp_is_mobile()) // On mobile { the_post_thumbnail_url(‘featured-image-mobile’); } else { the_post_thumbnail_url(‘featured-image’); }
You can use add_image_size to create your custom size like this: add_image_size( ‘featured-works’, 220, 180, true ); then get it like this: wp_get_attachment_image_src($thumbnail_id,’featured-works’); take into account how the crop works here
Sounds like several different pointers may be useful: Are you working on a theme that was custom developed for your website? If not, you should create a child theme so that anytime the parent theme receives an update, your changes won’t be overwritten. The image you’re trying to add should either be uploaded through WordPress’s … Read more
Instead of using the locationimage attribute, why not use the attachment ID? This will allow you to dynamically grab the URL to the file and will make getting other meta data such as the alt text much easier. Below is a rewritten version of hplocationsfn(). Usage example: [hpLocationSquare id=’2299′ link=’http://example.com’] Note that the link attribute … Read more
Here’s a solution that leverages the shortcode_atts_{shortcode} filter, where caption is the shortcode in this case. This works by pulling the attachment id from $out[‘id’] then getting the value of the class via get_post_meta( $attachment_id, ‘img_class_field’, true ). With this approach, it is not necessary to modify the output of the caption shortcode in the … Read more
Here’s an (untested) example where we inject into the header tag on attachment’s pages, the canonical link of the attached post: add_action( ‘wp_head’, ‘wpse_attachment_parent_canonical’ ); function wpse_attachment_parent_canonical() { // Only target attachment’s pages if( ! is_attachment() ) return; $object = get_queried_object(); // Make sure we’re dealing with a WP_Post object if ( ! is_a( $object, … Read more
You can use the get_avatar_url filter (see the arguments passed here in the source code) to change the avatar url and then simply use get_avatar() with the user email in the theme as you’re used to. add_filter(‘get_avatar_url’, ‘wpse_avatar_or_gravatar’, 10, 3); function wpse_avatar_or_gravatar($url, $id_or_email, $args) { // was id passed via $id_or_email if ($id_or_email == intval($id_or_email)) … Read more
Your image’s src is pointing to the full size image, so it’s not an issue of permalink. The issue happens because of the sizes values. There is a variable that determines the width of your content, which then later WordPress uses to generates the responsive sizes for your images. This global variable can be set … Read more
I’m sure some plugin or your theme modifies your attachment url. Try to find wp_get_attachment_url hook in your code or simply create your own with high priority this way: add_filter(‘wp_get_attachment_url’, function($url) { return preg_replace(“~^//(.+)$~”, “https://$1”, $url); }, 999); or better: add_filter(‘wp_get_attachment_url’, function($url) { return set_url_scheme($url, ‘https’); }, 999); But I recommend you to find the … Read more
