Make sure to set a nopriv hook for those who aren’t logged in. http://codex.wordpress.org/AJAX_in_Plugins#Ajax_on_the_Viewer-Facing_Side Also the JS variable ajaxurl is only set on the backend.

First, the sample WHERE clause you provide doesn’t make sense. That is not how to write a query that will return “between a range of startDate and endDate”. Secondly… I am basically looking for posts which are between a range of startDate and endDate and should show further posts also. It is not clear what … Read more
Been there done that. Try this: https://interconnectit.com/products/search-and-replace-for-wordpress-databases/ Its a search and replace tool that you put in your WordPress root and just run it from mydomain.dev/searchreplacedb2.php It fixes the serialization problem when you want to change the url:s to the live one.
The problem here is that post meta wasn’t designed for these kinds of searches, that’s why the taxonomy tables exist, else categories and tags would be stored as post meta Post meta is optimised for fetching data when you already know the post ID Taxonomies are optimised for finding posts when you already know the … Read more
Custom field for default gallery
get_users() does not allow you to directly sort by whatever you like, but there are ways around it. The Codex for get_users() says: orderby – Sort by ‘ID’, ‘login’, ‘nicename’, ’email’, ‘url’, ‘registered’, ‘display_name’, ‘post_count’, ‘include’, or ‘meta_value’ (query must also contain a ‘meta_key’ – see WP_User_Query). meta_value is a very powerful way to go … Read more
The Types plugin is making this about 10x harder than it needs to be, you’ll have to look through their documentation on the issue, but from what I can tell they don’t store items in the postmeta table in a straightforward way. I created a simple field with the plugin in a sandbox env and … Read more
It sounds like what you need is a custom secondary loop, probably using WP_Query, that just queries for your single most recent post. Once you have that, you can use get_post_meta() to grab the custom meta from that post in a new loop. Edit: Alternately, you can use get_posts() to get the first post’s ID … 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
You didn’t retrieve your 2 values in the save_post action. You need to get $_POST[’freebie-demo’] (it’s ok for it) and $_POST[‘freebie-downurl’] If you want an array post meta value based, you can do something like that : // Sanitize user input. $de_url[‘name’] = sanitize_text_field( $_POST[‘freebie-demo’] ); $de_url[‘url’] = esc_url($_POST[‘freebie-downurl’]); // Update the meta field in … Read more
