I use below code to list custom post types on homepage beside standard posts
<?php $args = array('post_type' => array( 'post', 'gallery_posts' )); ?>
<?php $query = new WP_Query( $args ); ?>
<?php if ( $query->have_posts() ) : ?>
<?php while ( $query->have_posts() ) : $query->the_post(); ?>
<?php _e('Read More', ''); ?>
<?php endwhile; ?>
<?php endif; ?>
What i should to do for change 'Read more' text for second type of post while looping?
