wp-admin/includes/ajax-actions.php:3427Handles sending a link to the editor via AJAX.
One hook fires while wp_ajax_send_link_to_editor() runs, in this order:
Filters the URL sent to the editor for a specific media type.
function wp_ajax_send_link_to_editor() { global $post, $wp_embed; check_ajax_referer( 'media-send-to-editor', 'nonce' ); $src = wp_unslash( $_POST['src'] ); if ( ! $src ) { wp_send_json_error(); } if ( ! strpos( $src, '://' ) ) { $src = 'http://' . $src; } $src = sanitize_url( $src ); if ( ! $src ) { wp_send_json_error(); } $link_text = trim( wp_unslash( $_POST['link_text'] ) ); if ( ! $link_text ) { $link_text = wp_basename( $src ); } $post = get_post( $_POST['post_id'] ?? 0 ); // Ping WordPress for an embed. $check_embed = $wp_embed->run_shortcode( '[embed]' . $src . '[/embed]' ); // Fallback that WordPress creates when no oEmbed was found. $fallback = $wp_embed->maybe_make_link( $src ); if ( $check_embed !== $fallback ) { // TinyMCE view for [embed] will parse this. $html = '[embed]' . $src .
