💡 Hint

Common Mistakes

Using the_post() in the while condition (it does not return a boolean).

Using non-existent methods like get_post() or next_post().

The method have_posts() is used in the while condition to iterate over the posts. the_post() sets up the post data inside the loop.

💡 Hint

Common Mistakes

Using 'post' instead of 'product' for post_type.

Setting posts_per_page to 10 instead of 5.

To query 5 recent 'product' posts, set post_type to 'product' and posts_per_page to 5.

  while ($query->[2]()) {

  }
}

💡 Hint

Common Mistakes

Using 'get_posts()' which returns an array, not a method of WP_Query.

Mixing up 'the_post()' and 'have_posts()' in the loop.

Use have_posts() to check for posts and as the loop condition, the_post() sets up each post inside the loop, and the_title() to display the title.
