php - Is this code protected against SQL injection? -


i'm not familiar newer php commands, wanted check if code below protected against sql injection?

$mysqli = new mysqli($server,$user , $password, $db_name); $stmt1 = $mysqli->prepare("insert $db_table (request_date, from_city, from_country, to_city, to_country, travel_date, return_date, minus, plus, currency)                                          values(?,?,?,?,?,?,?,?,?,?)");  $date = date('y-m-d h:i:s'); $stmt1->bind_param("ssssssssss",$date,                                 $_post['from_city'],                                  $_post['from_country'],                                  $_post['to_city'],                                  $_post['to_country'],                                  $_post['travel_date'],                                  $_post['return_date'],                                  $_post['minus'],                                  $_post['plus'],                                  $_post['currency']                     );  $stmt1->execute();

basically, script receives post data form, records them db, , submits them script perform actual search (on third-party website).

yes, prepared statements safe against sql injection not interpreted part of sql query - can have there, won't execute command.

that said, may want bit of validation anyway make sure data accepting makes sense. garbage in, garbage out. don't want save date that's not valid, instance.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
