Gregory Schulte (Children's Hospital Colorado) has alerted us that if the "short_open_tag" in the /etc/php.ini file of a server (of this web client plugin) is NOT set to* "on*", then the resulting exported Excel spreadsheet may be just a blank file.
...
- either change the "short_open_tag" in the /etc/php.ini file
toNo Format short_open_tag = On
- or change line 15 of the SaveToExcel.php file,
from
toNo Format <body><?=$_REQUEST['datatodisplay']?>
No Format <body><?php echo $_REQUEST['datatodisplay']?>
Of these, we recommend updating the the /etc/php.ini file.
BTW, after either change, as Yves Thorrez (Universitair Ziekenhuis Brussel) reminded us, one must clear the browser cache (close & restart browser session) to ensure the change takes effect.
Incidentally, we determined that this caveat exists for v1.0-2.0 of this web client plugin.
We do hope to have an updated SaveToExcel.php file (that takes care of this caveat without requiring the deployers to update their /etc/php.ini files) included in the next release of this web client plugin.
