php issue with inserting into sql

Question

I am having an issue inserting into mysql db using php. specifically this code is giving me problems:

$sql = "INSERT INTO '$mysql_database'.'$UsersTable' ('firstName', 'lastName', 'password', 'email','userType')VALUES ('$firstName', '$lastName', '$password','$email','$userType')";

I can't seem to find the error with syntax here. All the information to me seems correct. where am I going wrong ?

Answer 1

try this

$sql = "INSERT INTO $mysql_database.$UsersTable (firstName, lastName, password, email,userType)VALUES ('$firstName', '$lastName', '$password','$email','$userType')";

remove Quote from table column

Answer 2

试试这个查询

$sql = "INSERT INTO $mysql_database.$UsersTable (firstName, lastName, password, email,userType)VALUES ('$firstName', '$lastName', '$password','$email','$userType')";

Answer 3

Hello you can't use single Quote from table column name so remove it

$sql = "INSERT INTO $mysql_database.$UsersTable (firstName, lastName, password, email,userType)VALUES ('$firstName', '$lastName', '$password','$email','$userType')";

otherwise use this way

$sql = "INSERT INTO $mysql_database.$UsersTable (`firstName`, `lastName`, `password`, `email`,`userType`)VALUES ('$firstName', '$lastName', '$password','$email','$userType')";
