I think you are good, but you don’t need to use other functions. You have all in File: wp-includes/media.php For instance, you may _wp_get_image_size_from_meta to get the image dimensions, so you don’t need to use something like this: $size = getimagesize($file); $width = $size[0]; $height = $size[1]; $mime = $size[‘mime’]; To get the image dimensions … Read more
One way to do this would be to simply hide the upload/insert media button: and, then add featured image support for your themes posts, so a user can still attach images to the post. Hide upload/insert media button for your theme in: functions.php: function hideUploadInsert($hook) { if($hook != ‘post.php’ AND $hook != ‘post-new.php’) return; // … Read more
No luck by using plugin provided functions as it gets it’s id by $obj = get_queried_object(); To get the image I use this code snippet: $associations = taxonomy_image_plugin_get_associations(); $tt_id = absint( $taxonomy_term->term_id ); if ( array_key_exists( $tt_id, $associations ) ) { $image_id = absint( $associations[ $tt_id ] ); } $image = wp_get_attachment_image( $image_id, ‘thumbnail’ );
You will need to take a look at the image_send_to_editor filter. This will not update existing records but it if you get it working it will apply to each newly inserted image. very basic filter: function give_linked_images_class($html, $id, $caption, $title, $align, $url, $size, $alt=”” ){ $html; //contains the string you need to edit, you might … Read more
Additional image sizes for uploaded images are created by wp_generate_attachment_metadata() after the file has been uploaded. An array of available sizes is populated using get_intermediate_image_sizes() (thumbnail, medium, large + custom sizes) which is later used to create the images. Both of the above functions have filters for overriding the sizes available to WordPress during this … Read more
I will allow myself to expand on Ricks answer as there are a few ways to change old domain to new domain and each might be helpful depending on your situation. 1) use the Better Search and Replace plugin https://wordpress.org/plugins/better-search-replace/ plugin as suggested in the answer above. 2) use Database Search and Replace script https://interconnectit.com/products/search-and-replace-for-wordpress-databases/ … Read more
You can remove it right before post is printed to the screen by stripping it out from content. But remember it still will meddle in Editor. <?php function my_remove_rel_attr($content) { return preg_replace(‘/\s+rel=”attachment wp-att-[0-9]+”/i’, ”, $content); } add_filter(‘the_content’, ‘my_remove_rel_attr’);
I am assuming that WP takes the additional parameters at the end of the file name to automatically resize the image… WordPress adds those suffixes when it creates the images, which is typically done on image upload. Those images should be on the server. By default (and if I am not mistaken), WordPress does not … Read more
You can use several functions to get the URL of a image of any of the intermediate sizes created by WordPress (thumbnail, medium, large, full, or any other custom size). You can use get_the_post_thumbnail()/the_post_thumbnail(): use this function if you want to get a <img> element of the featured image of a post (aka “post thumbnail”). … Read more
I think that you’re adding the code inside the loop of index.php or blog template file. You might be try this kind of things: if ( class_exists( ‘MultiPostThumbnails’ ) && ( MultiPostThumbnails::has_post_thumbnail( get_post_type(), ‘header-image’ , get_the_ID() ) ) ) { MultiPostThumbnails::the_post_thumbnail(get_post_type(), ‘header-image’, NULL, ‘header-image-full’, array(‘class’ => “custom-header-image”) ); } else { $image = get_template_directory_uri() .’/assets/img/placeholders/placeholder.png’; … Read more
