otrzymuję dane przez GET-a mam taki kod
$dbconnect = mysql_pconnect($server, $dbusername, $dbpassword);
$dbselect = mysql_select_db("test",$dbconnect);
// Prepare the SQL statement
$sql = "INSERT INTO test.sensor (value,value2,value3,value4,value5)
VALUES ('".$_GET["wewn"]."', '".$_GET["piec"]."', '".$_GET["zew"]."', '".$_GET["humid"]."', '".$_GET["jasno"]."')";
mysql_query($sql);
i dostaję takie błędy
Notice: Undefined index: wewn in C:\xampp\htdocs\time\write_data.php on line 20
Notice: Undefined index: piec in C:\xampp\htdocs\time\write_data.php on line 20
Notice: Undefined index: zew in C:\xampp\htdocs\time\write_data.php on line 20
Notice: Undefined index: humid in C:\xampp\htdocs\time\write_data.php on line 20
Notice: Undefined index: jasno in C:\xampp\htdocs\time\write_data.php on line 20
