There isn’t really a built-in way to return all the posts that an attachment is used in. The closest thing would probably be $post->post_parent which all attachments have post parents. There is a plugin called Find Posts Using Attachment that does a good job of retrieving these and is a single file PHP class so … Read more
Like almost all content in WordPress, a Media item (aka attachment) is stored in the wp_posts table, and its metadata is stored in the wp_postmeta table. The wp_postmeta data is linked to the post by the post ID. If the Media item is set as an attachment to a specific post, then inside the wp_posts … Read more
After searching through the wordpress docs, I found what I needed. What I was missing was the hook called “the_content”. My function, and all the code I wrote inside it, was correct. I just needed this stupid hook. function displayIframe($content) { //[my code to get the $currentPostID and $currentPostGuid] //… //… if (is_single( $currentPostID )) … Read more
You can’t attach from a URL. So https://ucarecdn.com/8aa17c61-bd55-4311-8b45-7d9a2efde6c5/ won’t work. You need an absolute path to the file, such as /path/to/my/file.ext. But there are some other problems with your code snippet as well. You use $email_attachement (with a ..chement…) in one place, but then $email_attachment in your wp_mail() call. Also, your “attachment” isn’t a file. … Read more
I was asking the same question in the comments of another question. The solution is (thanks to Кирилл-Меркушев), to get another URL from the onSelect Callback. Before I had this: function onSelectImage( media ) { props.setAttributes( { mediaURL: media.url } ); props.setAttributes( { mediaID: media.id } ); } Then I console logged the media parameter, … Read more
My first recommendation would be to use Advanced Custom Fields to setup a gallery rather than using this method. However, I think you may be able to load your images using Add Media -> Create Gallery which will add a shortcode to your post content You could then use the_content filter and strip_shortcodes to remove … Read more
Depending on how those inbound links work, this could be simpler than you think. If the links are direct to files in the file system, WordPress isn’t actually needed at all – just a corresponding path for a valid URL. So let’s say you install WP today, the ‘earliest’ folder in uploads will be 2020/09. … Read more
You can easily inspect all the metadata for any post like so: // 123 is the (attachment) post ID var_dump( get_post_meta( 123 ) ); And in a default WordPress setup with no plugins or theme which add custom metadata to the image attachment post, the metadata you’d get are: _wp_attached_file — string, the image file … Read more
So I must be missing some essential piece that preserves html. No, your code is OK. However, I would require the second parameter ($editor_id) and check whether its value is attachment_content which is the editor ID for the media description textarea on the “Edit Media” page. I also wouldn’t add the ‘textarea_name’ => ‘content’ part. … Read more
There is to filters needed for optimizing all images, that will be uploaded: add_filter(‘wp_handle_upload’, ‘random_function’, 10, 2); add_filter(‘image_make_intermediate_size’, ‘rand_function2’, 10, 1); function random_function($array, $string) { // Some random action with main image return $array } function rand_function2($file) { // Some random action with cropped images return $file }
