I've been testing this grid for a week so far (samples run fine), but for some reason my first real test (against one of my ongoing project's DB) shows me no records at all.
Ok, 10 minutes after I posted this question, I found the cause.
My PHP script wasn't setting the $_GET[sidx] variable, making my SQL syntax as this:
SELECT … FROM … ORDER BY 0
and thus the SQL sentence giving an error. This wasn't happening when I run my php script from the browser bc $_GET[sidx] was not defined. So beware folks to properly manage default variables in your PHP scripts! they might come empty!
