In WordPress, if you want to use multiple loops on a page, you will need to reset the loops.
For example, if you use WP_Query to display both navigation and content. In this case, you will need to reset the loop once it has ended before starting another loop again.
<?php rewind_posts(); ? >By calling this function, you can reset the loop for the current WP_Query object. As a result, it is possible to start the loop again.
However, rewind_posts() only resets the current query, it does not create a new query. Therefore, if you want to create a new query and start a loop, use the wp_reset_query() function instead.
