This thread is resolved. Here is a description of the problem and solution.
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]
