The filter on posts_orderby should return a string that does not begin with ORDER BY, WordPress will add that itself. By default WordPress will filter by post_date. If you don’t want that, you should overwrite the order clause, not append to it. So your filter should look like this: function filter_orderby( $orderby ) { global … Read more
For this to work reliably, the date format in the database should be yyyy-mm-dd. Comparison type should be DATE or NUMERIC. If you take the date of 25-04-2012 in present format and compare it numerically to the date 26-04-1986, you can see what the issue will be: 25042012 < 26041986 ALso- if you’re doing these … Read more

<?php function add_subtitle($title, $id) { $subtitle = get_post_meta($id, ‘myCustomField’, true); $new_title = $title; if(!empty($subtitle)) $new_title = $subtitle . ‘: ‘ . $new_title; return $new_title; } add_filter(‘the_title’, ‘add_subtitle’, 10, 2); Basically, this uses the the_title filter to add the subtitle to your title.

Using your constructed array, I think this is the correct syntax: $meta_query_args = array( ‘meta_key’ => ‘price’, ‘meta_value_num’ => 1000, ‘meta_compare’ => ‘<=’, ‘meta_query’ => array( ‘relation’ => ‘OR’, array( ‘key’ => ‘roomcount’, ‘value’ => 3, ‘type’ => ‘numeric’, ‘compare’ => ‘>=’ ), array( ‘key’ => ‘bathroomcount’, ‘value’ => 2, ‘type’ => ‘numeric’, ‘compare’ => … Read more
<?php $total = 0; while(the_repeater_field(‘repeater’ )): the_sub_field(‘space_avail’ ); $total += intval( get_sub_field(‘space_avail’ ) ); endwhile; echo $total; ?> Notice the intval. It tells php to consider the result as an number, not as a string
if you want to process the field after submitting, php’s number_format function is what you need: $price = number_format( $number, 2, ‘.’, ‘,’ ); but if you want to change how the number is displayed as it’s typed in, try jQuery autoNumeric
