    I have 3 items in 1 line. with a <br> in the end.

    I want this: if any 3 items exit data, then show it, else nothing show up.

    I know there is [if][/if] tag can make 1 item show or not, but with a <br> in the end for 3tems. I have no idea how to make it happen.

    Anyone can help？

    Hi @freezhao

    I’m not sure I follow the issue here. Can you elaborate with code examples?

    Cheers, Jory

    @freezhao Here’s what you’ve described as a shortcode, [three-items], which outputs meta values for foo, bar, and baz separated by commas and followed by a <br/> if at least one of them is not empty:

    <?php

add_shortcode(
	'three-items',
	function( $atts, $content, $shortcode_tag ){
		ob_start();

		$items = [
			get_post_meta( get_the_ID(), 'foo', true ),
			get_post_meta( get_the_ID(), 'bar', true ),
			get_post_meta( get_the_ID(), 'baz', true ),
		];

		foreach( $items as $key => $item ) {
			if ( empty( $item ) ) {
				unset( $items[ $key ] );
			}
		}

		if ( ! empty( $items ) ) {
			printf(
				'%s<br/>',
				implode( ', ', $items )
			);
		}

		return ob_get_clean();
	}
);
