Hi @flegma
You should be able to query by minimal value like
array(
'key' => 'single_villa_prices_%_price',
'value' => $price_min,
'compare’'=> '>',
)
if you only want to query a specific rows meta you can simply do:
array(
'key' => 'single_villa_prices_0_price',
'value' => $price_min,
'compare’'=> '>',
)
and ignore the posts_where filters.
Best of luck!
