Meta Box

Thanks a lot, it works like a charm.

Hello,
thank you. I think I might still need your help in the thread:
this is the code (comments show the problem):

<?php /* Template name: Categories */ ?>
<?php 

get_header();

$categories = get_categories();

foreach ($categories as $cat) {
	
	echo $cat->name; //yields category name
	echo '<br><br>';

	$images = get_term_meta( $cat->term_id, 'image_advanced', false ); //yields an array of strings, i.e. "4"
	echo '<br><br>';	

	if ( $images ) {
	    foreach ( $images as $image ) {
	        echo "<a href='{$image['full_url']}' rel='lightbox'><img src='{$image['url']}' width='{$image['width']}' height='{$image['height']}' alt='{$image['alt']}' /></a>";

	        /*  this echo line yields:
				Warning: Illegal string offset 'full_url' in categories.php on line 18
				Warning: Illegal string offset 'url' in categories.php on line 18
				Warning: Illegal string offset 'width' in categories.php on line 18
				Warning: Illegal string offset 'height' in categories.php on line 18
				Warning: Illegal string offset 'alt' in categories.php on line 18
	        */
	    }
	}

	$images2 = rwmb_meta( 'image_advanced'); //this method returns an empty string, why?

	var_dump($images2);
}

// Restore original Post Data
wp_reset_postdata();

?>

<?php get_sidebar(); ?>
<?php get_footer(); ?>

Please advise...
Thanks!
