    I have defined three custom fields namely and i have them in my page-home.php. It gives me back the image url

    $inside_image_1 = get_field(‘inside_image_1’);
    $inside_image_2 = get_field(‘inside_image_2’);
    $inside_image_3 = get_field(‘inside_image_3’);

    I want to have some something like

    <a class="project-item web-design" href="http://www.ynnt.com" data-images="assets/projects/folder/web.jpg,assets/projects/folder/lh.jpg">

    The custom field is not required. I want to write a query to display image 1 url if user has uploaded one, display image1 and 2 and three if he has uploaded both or all the images like above where user has two images uploaded.

    You can run conditional statements and if they’re true add them to a previously empty array. Then use PHP’s implode() function to seperate the array by commas. Here we store everything in a $images_array array variable:

    <?php
	$inside_image_1	= get_field( 'inside_image_1' );
	$inside_image_2	= get_field( 'inside_image_2' );
	$images_array 	= array();

	if( ! empty( $inside_image_1 ) ) {
		$images_array[] = $inside_image_1;
	}

	if( ! empty( $inside_image_2 ) ) {
		$images_array[] = $inside_image_2;
	}
?>

	<a href="example.com"<?php echo ( ! empty( $images_array ) ) ? ( 'data-images="' . implode( ',', $images_array ) . '"' ) : ''; ?>>Somekind of Link Text</a>
