Help with convert .htaccess to nginx :(

[Giang]

Thank you. I've changed as you suggested, but it still hasn't worked.
When I clicked Next button, it just reloaded the page.

Here is my new nginx configuration file content:
	location ~ \.(lock|conf)$ { deny all; }
	location ~ pre_.+\.php$ { deny all; }
	location ~ /[^.]+$ {
		try_files $uri $uri/ $uri.html /index.php;
	}
	location ~ \.php(/.+)$ {
		fastcgi_split_path_info ^((?U).+\.php)(/?.+)$;
		fastcgi_param SCRIPT_FILENAME
/var/www/siwapp/web$fastcgi_script_name;
		fastcgi_param PATH_INFO $fastcgi_path_info;
		fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
	}
