In WordPress, you can retrieve the 'alt' text of an image using PHP within your theme files. Here's a simple way to do it:
Firstly, ensure that you've assigned an alt text to the image via the WordPress Media Library.
In this code snippet:
get_post_thumbnail_id()retrieves the ID of the featured image (thumbnail) of the current post in the loop.
get_post_meta()is a WordPress function that retrieves the metadata for a particular post. In this case, we're fetching the image's alt text which is stored with the meta key
get_post_thumbnail_id() with the actual ID of your image if you want to get the alt text of a specific image.
This method requires you to edit your theme files directly. Be careful when making these changes and always keep a backup of your original files. If you're uncomfortable making these changes, consider reaching out to a developer or using a WordPress plugin that allows for easy alt text retrieval and editing.
