Passing undefined variables #4
Description
For issues like the following:
PHP Notice: Undefined index: data in /var/www/php/maps_feed.php on line 27, referer: http://localhost/
I've been setting the PHP to assume a value of 'null' if the variables in question are passed undefined, but I suspect it may be best practice to fix that in the JavaScript that calls it. I see the maps_feed.php call at line 72 in js/tidepoolsframeworks/map_rendering.js , for example, but I don't know the jQuery syntax for initializing 'data' to 'null' if it doesn't get any results when it looks for :maps. Thoughts?
