hi, i find this custom_truncate,for cut text on right side,but not understand how cut in right side,beacause also custom_truncate cut always on left side  

Add custom truncate#

To add a custom truncate option to the [frm-field-value] shortcode, follow the example below. Usage example: [frm-field-value field_id=x custom_truncate=1]
add_filter( 'do_shortcode_tag', 'truncate_frm_field_value', 10, 3 );
function truncate_frm_field_value( $output, $tag, $attr ) {
	if ( 'frm-field-value' === $tag && isset( $attr['custom_truncate'] ) && is_numeric( $attr['custom_truncate'] ) ) {
		$output = FrmAppHelper::truncate( $output, $attr['custom_truncate'] );
	return $output;

truncate always reduces the length of a string from the right. This is how PHP works. If you want to get a portion of a string or remove characters from the left side, use substr.
