*I thought I will write this as an update but then I thought it is better to provide the solution as an answer because someone may skip the solution in the question update. There is no mistake in my code or in the loop for that matter. This is not a server misconfiguration either. As … Read more
function get_attachment_id_from_src ($image_src) { global $wpdb; $query = “SELECT ID FROM {$wpdb->posts} WHERE guid=’$image_src'”; $id = $wpdb->get_var($query); return $id; }
Take a look at side loading images. media_sideload_image()/wp_handle_sideload() and get the ID from the URL. attachment_url_to_postid. <?php $url = “http://wordpress.org/about/images/logos/wordpress-logo-stacked-rgb.png”; $title = “Some Image Title”; $alt_text = “Some Alt Text”; require_once(ABSPATH . ‘wp-admin/includes/media.php’); require_once(ABSPATH . ‘wp-admin/includes/file.php’); require_once(ABSPATH . ‘wp-admin/includes/image.php’); // sideload the image — requires the files above to work correctly $src = media_sideload_image( $url, … Read more
function has_image_attachment($post_id) { $args = array( ‘post_type’ => ‘attachment’, ‘post_mime_type’ => ‘image/jpeg’, ‘numberposts’ => -1, ‘post_status’ => null, ‘post_parent’ => $post_id ); $attachments = get_posts($args); if(is_array($attachments) && count($attachments) > 0) { //Has image attachments return true; } else { return false; } }
This may not be the most elegant way to do it (I’m not sure if overwriting the $_FILES global is even allowed) but this seems to work: global $post; if ($_FILES) { $files = $_FILES[‘upload_attachment’]; foreach ($files[‘name’] as $key => $value) { if ($files[‘name’][$key]) { $file = array( ‘name’ => $files[‘name’][$key], ‘type’ => $files[‘type’][$key], ‘tmp_name’ … Read more
Why not cover this in your query and use isNull() ? When your meta_key is null for this attachment it is true.
In case if your images are lying in some other folder of your previous wordpress install, then did you try copying that entire folder in your current install?
As far as I know, you’d have to use a combination of built-in functions to achieve this. If there is a plugin, you’d have to research for “Bulk parent” or “Bulk re-attachment”. Unless you have a logic connecting those posts, I think you’d have to do it post by post. Be it with PHPMyAdmin (changing … Read more
If you need to retain only images for last 50 posts, I don’t think that a cron job or a WP cron is the best thing you can do, in WordPress you can know when a post is published, and you can run a routine everytime it happen, deleting images for the post pubblished 50 … Read more
Some ideas for your attachments file: A simplification: $tmp = $post; // Store the current global post object $post = get_post( $post->post_parent ); // Use the post parent post object $media = get_attached_media( ‘audio’ ); if( $media ) { $sc = “”; if( count( $media ) > 1 ) { $ids = join( ‘,’, wp_list_pluck( … Read more
