Prompt Detail:

To create a WordPress shortcode that displays the category image of the current post, you can follow these steps:

  1. Add the shortcode function to your theme's functions.php file or a custom plugin:
php
function category_image_shortcode() { // Get the current post object global $post; // Get the categories assigned to the post $categories = get_the_category($post->ID); // Check if there are categories assigned to the post if ( !empty($categories) ) { // Get the first category assigned to the post $category = $categories[0]; // Get the category thumbnail (if any) $category_thumbnail_id = get_term_meta( $category->term_id, 'thumbnail_id', true ); // Check if the category has a thumbnail if ( !empty($category_thumbnail_id) ) { $category_image = wp_get_attachment_image_src( $category_thumbnail_id, 'full' ); // Display the category image if ( $category_image ) { return '<img src="' . esc_url( $category_image[0] ) . '" alt="' . esc_attr( $category->name ) . '">'; } } } return ''; // Return empty string if no category image is found } add_shortcode('category_image', 'category_image_shortcode');
  1. How to use the shortcode: You can use the shortcode [category_image] anywhere in your posts, pages, or widgets to display the image associated with the first category of the current post. If no image is associated with the category, nothing will be displayed.

Make sure to check if your categories have thumbnail images assigned to them. The above code assumes that the category images are set as term meta with the key 'thumbnail_id'. If your theme/plugin uses a different method for storing category images, you'll need to adjust the code accordingly.

This shortcode function fetches the first category assigned to the current post and retrieves its thumbnail image if it exists, and then returns the image tag.
