 ".'$State'.",".'$ZIP'.",".' $age'." , ".'$Ethnicity'.",".'$date'.")";

Answer 1

列数不匹配。如果是自动增量，则无需指定ID。

同样'$something'将逐字插入 $ something 。您希望使用"插入动态数据。

$sql = "INSERT INTO Visitors
(first_name, last_name, Email_address, Phone_no, St_Addr, city, State, zip, age, Ethnicity, Signup_Date) 
VALUES 
('".$firstname."', '".$lastname."', '".$email."', '".$telephone."', '".$Street_Address."', '".$City."', '".$State."','".$ZIP."','". $age."' , '".$Ethnicity."','".$date."')";

插入查询不能正常运行php
