set uppercase in validate field

Hello @carioti

You can create a custom validation rule following this article.

Here is an example of uppercase validation action:

function um_custom_validate_uppercase_characters( $key, $array, $args ) {
	if ( isset( $args[$key] ) && !preg_match('/[A-Z]/', $args[$key]) ) {
		UM()->form()->add_error( $key, __( 'Please enter uppercase characters', 'ultimate-member' ) );
	}
}
add_action( 'um_custom_field_validation_uppercase_characters', 'um_custom_validate_uppercase_characters', 30, 3 );

Thanks Aswin,
I put the code in the theme’s functions.php.
The function i recalled in the “custom action” field is “uppercase_characters” but
It seems not working. Do I have to put the code in a different page?

Adding it to functions.php should work fine. Please try following codes if above one didn’t work for you:

function um_custom_validate_uppercase_characters( $key, $array, $args ) {
	if ( isset( $args[$key] ) && ! ctype_upper( $args[$key]) ) {
		UM()->form()->add_error( $key, __( 'Please enter uppercase characters', 'ultimate-member' ) );
	}
}
add_action( 'um_custom_field_validation_uppercase_characters', 'um_custom_validate_uppercase_characters', 30, 3 );
