WPForms: change the export CSV file separator.

wpforms-export-change-separator.php

<?php

// For WPForms < v1.5.5, but should work with the latest version as well.
add_filter( 
	'wpforms_csv_export_separator', 
	function( $sep ) {
		return ';';
	} 
);

// Snippet below works since WPForms v1.5.5.
add_filter(
	'wpforms_pro_admin_entries_export_configuration',
	function( $config ) {
		$config['csv_export_separator'] = ';';

		return $config;
	}
);

this hook is deprecated since 1.5.5 of the WPForms plugin but usage of configuration['csv_export_separator'] is not working in some versions.

@fcamichel, could you please elaborate on this? In which situations isn't it working?

@slaFFik, we found out that with some of our themes our defined filter is never called. We fixed that with inserting your code into a custom plugin, called before the wpforms plugin (see https://wordpress.stackexchange.com/a/215651).

@fcamichel
Oh, correct, that's not the problem with the filter, but with the hooks loading order.

I usually create wp-content/mu-plugins/wpforms.php and put there all the filters/actions that are related to the WPForms plugin, and do the same for other plugins (like wp-mail-smtp.php etc). This helps keep everything organized.
