Problem:
How to add a conditional test for the length of the value of a custom field.

Solution:
Register a custom shortcode to get the length of a field passed as an attribute for the current post by adding the following to your theme's functions.php:

/**
 * Register shortcode "fieldlength"
 * 
 * requires attribute field = "slug" of field to measure length of
 */
add_shortcode( 'fieldlength', function( $atts ){
 
    global $post;
 
    $string = get_post_meta( $post->ID, $atts['field'], true);
 
    return strlen( $string );
});

Register the custom shortcode at Toolset > Settings > Front-end Content and then use it inside a wpv-conditional shortcode like so:

[wpv-conditional if="( '[fieldlength field='wpcf-author-name']' gt '15' )"]
Length > 15
[/wpv-conditional]
