When importing posts to a new site if XML file has postmeta not setup on new server what happens?

Use an id on a button to update_post_meta in post
As @s_ha_dum has stated, your syntax mixes JS and PHP; and Ajax wil be needed. I’ll try to point you in the correct direction. This should be your javascript: jQuery(document).ready(function($) { $(‘button#rsvp_button’).click(function qwe4_tracker(){ var data = { action: ‘my_action’ }; $.post(ajaxurl, data, function(response) { //alert(‘Got this from the server: ‘ + response); // Uncomment to … Read more
Sorting meta box values by start- and enddate and all dates in between
I think you can do the trick running 2 loops, in the first you prepare an helper array of posts ordered by date, in the second you display this array: Something like this (completely untested): if ( $agenda_query_full->have_posts() ) { $date_events = array(); // helper array $today = date(‘Y-m-d’); while ( $agenda_query_full->have_posts() ) { $agenda_query_full->the_post(); … Read more
How to get pictures of the WordPress post
When you upload an attachment from the post edit screen, WordPress set the current post ID as the post_parent of the attachment. And that’s how you get these attachments: $post_ID = 123; $attachments = get_posts( array( ‘post_type’ => ‘attachment’, ‘post_status’ => ‘inherit’, ‘post_parent’ => $post_ID, ‘post_per_page’ => -1, ‘post_mime_type’ => ‘image/*’ ) ); foreach ( … Read more
How do I delete element from a serialized array upon deletion of a post?
Don’t focus on serialized aspect of it. Retrieve data using appropriate API function. Modify the data. Save data back. WordPress APIs take care of serialization transparently, no need to mess with it directly.
How to update the ‘modified_time’ of a post ONLY when content is changed?
I guess, there is no exact way of retrieving the time only when the post’s content is updated until you change the core functionality of wordpress and that might lead to some other issues. But here is a workaround I would like to propose here. You can retrieve the time/date only when content is updated … Read more
How can I prevent the post_modified column in wp_posts from being updated?
Add the following to functions.php when you are meddling and remove it after, or comment it out: function no_mod_wpse_136092($data,$postarr){ if (empty($postarr[‘ID’])) return $data; $old = get_post($postarr[‘ID’]); if (!empty($old)) { $data[‘post_modified’] = $old->post_modified; $data[‘post_modified_gmt’] = $old->post_modified_gmt; } return $data; } add_action(‘wp_insert_post_data’,’no_mod_wpse_136092′,10,2);

Posts with no meta field do not appear when sorting by meta field
I believe if you specify ‘meta_key’ without a ‘meta_value’ it checks merely for the existence of the meta_key. I haven’t tried this but you might be able to specify a ‘meta_compare’ of ‘!=’ and some random value for ‘meta_value’ that you know would never actually be set as the value. $query->set( ‘meta_key’, ‘fieldA’ ); $query->set( … Read more
