Question

I have two codes to put data into database but it is generating error, check out the code below.

$email = "[e-mail]"; //email

$pass = "helloworld";  //password

$fname = "Example";  //first name

$lname = "Man"; //last name

$birth = "2012-2-1"; //birthday

$gender = "male"; //gender

$site_prefix = "my_"; //table prefix

THIS CODE DOESNT WORK AND OUTPUT AN ERROR

$sql = "
INSERT INTO `{$site_prefix}login` (`email`,`pass`) 
VALUES ('$email','$pass');
INSERT INTO `{$site_prefix}users` (`fname`,`lname`,`birthday`,`gender`)
VALUES ('$fname','$lname','$birth','$gender')";

mysql_query($sql,$con) or die(mysql_error());

ERROR
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘INSERT INTO my_users (fname,lname,birthday,gender) VALUES (‘Example’,’Ma’ at line 2

THIS CODE WORK NORMALLY

$sql = "INSERT INTO `{$site_prefix}login` (`email`,`pass`) VALUES ('$email','$pass');";

$sql1 = "INSERT INTO `{$site_prefix}users` (`fname`,`lname`,`birthday`,`gender`) VALUES ('$fname','$lname','$birth','$gender')";

mysql_query($sql,$con) or die(mysql_error());
mysql_query($sql1,$con) or die(mysql_error());

Answer 1

mysql_query cannot process multiple statements in one query.

From the docs:

mysql_query() sends a unique query (multiple queries are not supported) to the currently active database on the server that’s associated with the specified link_identifier

Use mysqli (with mysqli_multi_query) if you need this functionality.
