You can use PHP’s fgetcsv() or str_getcsv() function to parse the uploaded CSV file. Your CSV will need to include a column with the Post’s ID as well as the columns matching up to your custom field names.

get_the_ID() fails the first time, returns a value the second time it’s called
I Found my mistake. Basically, I had a bad prefix… I changed the function name of the get_post_meta to $gwrrest_stored_meta but then missed it in the echo of the text area content. I had “recycled” my code and accidentally left is as $prfx_stored_meta.

The custom fields I am using are from the plugin ACF (Advanced Custom Fields). I finally looked at the ACF website, which I should have done originally, and found the function get_field can specify a post so here is the working code: $posts = get_posts(array( ‘numberposts’ => -1, ‘post_type’ => ‘post’,)); foreach($posts as $post) { … Read more
Problem solved, I’ve used this: $d=new WP_Query( array( ‘category__in’ => array(4), ‘post_type’ => ‘post’, ‘posts_per_page’ => ‘-1’, ‘orderby’ => ‘meta_value’, ‘order’ => ‘ASC’, ‘meta_query’ => array( ‘relation’ => ‘AND’, array( ‘key’ => ‘data’, ‘value’ => $t, ‘compare’ => ‘<=’ ), array( ‘key’ => ‘data’, ‘value’ => $o, ‘compare’ => ‘>=’ ) ), ) ); Instead … Read more
