Provide me with explanation for given snippet, ensure the explaination is clear, concise and readable.
The given code is a snippet of PHP that used to query and display a slider gallery of car images on WordPress website. Let me break it down for you:
The code starts by creating a new WordPress query to retrieve posts of the custom post type "cars" a limit of 10 posts.
Inside the loop, it checks if there are any images attached to the current car post using the Advanced Custom Fields plugin. The get_field('gallery') function retrieves the images associated with the gallery field for the current post.
If images are found, it then loops through each image and displays them inside a slider using the FlexSlider plugin.
For each image, it the URL, alt text, and caption using the ACF functions, and then displays them as a slide in the slider. The image URL is used as the src attribute, the alt text is used for the alt attribute, and the caption is displayed as a paragraph below the image.
The code should also include a closing statement for the if condition and the while loop, and any necessary cleanup functions for the WordPress loop, such as wp_reset_postdata().
Overall, the code is designed to query for car posts and display a slider gallery of car images using the FlexSlider plugin, with image data retrieved using Advanced Custom Fields.
