How use WP_QUERY for this inputs ?!

Answer 1

More fields Plugin is to enter additional input into the post, page etc. And that is Custom Fields in WordPress.

To use WP_Query() for those Custom Fields input, you have to query for the meta_key.

<?php
//Query for only my custom field value
$args = array(
          'meta_key' => 'your_field_key'
        );

$wpse_query = new WP_Query($args);

while( $wpse_query->have_posts() ):
$wpse_query->the_post();

   if( get_post_meta( $post->ID, 'your_field_key', true ) != '' ):
      echo get_post_meta( $post->ID, 'your_field_key', true );

endwhile;
?>

Additionally, More Fields plugin is not actively maintained, so it's not fit for updated WordPress. Better use other plugins like: Advanced Custom Fields, or the like.
