Re: Notice

Well, i'm not totally sure that you can't catch a notice on php, but even if possible, it wouldn't be a good choice from my point of view.. A good approach would be test if the $data array really has the $loci position set before trying to use it.. something like: if ( isset($data[$ids][$loci]) ) { $alelleY = $data[$ids][$loci]['alelleY']; $alelleX = $data[$ids][$loci]['alelleX']; } And then you could choose your best approach to deal with this.. You could raise and exception in an else statement, or you could just set the $alelleY and X variables with something like 'Not found' Altough it's possible to mix javascript with php, I can't imagine why would you show the errors with javascript... unless of course, if you're using ajax for this.. 2014-03-27 8:36 GMT-03:00 Tiago Hori <tiago.hori@gmail.com>: > Hi Ricardo, > > Thanks! > > I figured it out last night the entries on the database were incomplete, so that makes perfect > sense with what you are saying.
