Re: Notice

Hi Tiago, *Notice*: Undefined index: in */Applications/MAMP/htdocs/catcnew/snppitv1.php* on line *62* *Notice*: Undefined index: in */Applications/MAMP/htdocs/catcnew/snppitv1.php* on line *63* These two, as I think, were raised because of lines below. You tried to access $data array on $loci position, what i'm guessing that is probably inexistent on this array. I suggest you to see what values do you have on $snp array and compare to $row[6] to see if they match each other. $alelleY = $data[$ids][$loci]['alelleY']; $alelleX = $data[$ids][$loci]['alelleX']; *Notice*: Array to string conversion in */Applications/MAMP/htdocs/catcnew/snppitv1.php* on line *66* The last notice is certainly raised because you are trying to use an array as a string on the line below. $role is an array, right? You could use explode function to turn each value from $role into a string separated by comma for example. $body .= "$ids\t$role\t" . substr($content, 0, -1) . "\n"; Good luck 2014-03-26 20:30 GMT-03:00 Tiago Hori <tiago.hori@gmail.com>: > Hi Everyone, > > I am at loss so I am hoping your wisdom can help me. > > I originally had a script that first got a list of terms to be searched > from the file uploaded in the first part.
