When you insert an image into a WordPress post, its display size is determined by the size setting you pick on the insert dialog: If your server is configured to support WordPress’s image resizing (most common hosts configure their servers so this isn’t an issue), a resized version of the image you enter should be … Read more
While you can do this with WP_Query, I’d do this the way you are trying to avoid– save a list in a separate key. The “pros” strongly outweigh the “cons” in my mind. LIKE queries with wildcards, especially with leading wildcards, are not efficient– aka, “slow” and a LIKE query on serialized data is going … Read more
<?php /* * Template Name: Gallery Page */ $query_images_args = array( ‘post_type’ => ‘attachment’, ‘post_mime_type’ => ‘image’, ‘post_status’ => ‘inherit’, ‘posts_per_page’ => – 1, ); $query_images = new WP_Query( $query_images_args ); ?> <?php get_header();?> <div class=”main”> <div class=”row”> <?php foreach ( $query_images->posts as $image ) {?> <div class=”col-md-3″> <img src=”<?php echo wp_get_attachment_url($image->ID); ?>” > <a … Read more
On the back-end, you’re retrieving the data like this: $meta = $_POST[‘attachments’][ $post_id ][‘photo_time’]; $meta_two = $_POST[‘attachments’][$post_id][‘photo_order’]; So on the front-end, you should set the field’s name in this format: attachments[<?= $vP ?>][KEY] where KEY could be either photo_order or photo_time. echo ‘<input type=”hidden” name=”attachments[<?= $vP ?>][photo_order]” class=”photo_order” value=”‘.$Por.'” />’; echo ‘<input type=”text” name=”attachments[<?= $vP … Read more
Try this: function delete_attachment() { $id = $_POST[‘att_ID’]; // the attachment ID // Deletes the attachment (and all of its custom fields or meta data; e.g. // `photo_order`). The `true` bypasses the trash. $att = wp_delete_attachment( $id, true ); // Deletes all custom fields named `vid_pix` where the value (`meta_value`) // is the attachment ID … Read more
If you want the image’s URL to be different, you need to first copy the image file to the user-specific folder and then create a new attachment for that copied image — i.e. clone the image’s “post” data. So replace this: // Get the attachments (IDs) attached to the `property` CPT. $prop_att_ids = (array) get_post_meta( … Read more
Regex to turn embedded images in to attachments
I think I found it myself. Now I’ve successfully managed to add a /photos endpoint to a permalink URL, such as: http://mywordpressite.com/projects/a-project/photos And then a custom template, photos.php will load and show – with access to the global $post variable. Helpful links: http://codex.wordpress.org/Rewrite_API/add_rewrite_endpoint http://codex.wordpress.org/Template_Hierarchy In my functions.php I added functions for the single_template and query_vars … Read more
This is a problematic idea. WordPress do not have any strong connectivity between an image (or any other uploaded file) and any content (post). This means that in theory you can not make a decisions like if it is an image on page do X as nothing ensures you that the image will not be … Read more
You can use get_attached_file() to: Retrieve attached file path based on attachment ID. And get_post_thumbnail_id() to determine the post thumbnail of the current post, or any post if you set the $post_id parameter. Exemplary usage: $bytes = filesize( get_attached_file( get_post_thumbnail_id() ) ); Use size_format() to Convert a given number of bytes into a human readable … Read more
