INSERT query of xampp MySQL doesn't work

Question

This php insert query is not working in MYSQL xampp. I couldn't find any error

QUERY:

$query = "INSERT INTO member (id, username,fname,lname,email, password, salt )
VALUES ( '$username', '$password', '$email', '$salt' )";

Answer 1

you are missing $fname, $lname in query also use NULL for id if auto incremented

$query = "INSERT INTO member (id, username,fname,lname,email, password, salt )
VALUES (NULL, '$username', '$fname', '$lname', '$password', '$email', '$salt' )";

Answer 2

you are passing wrong number of column names.your correct query should look like this:

$query = "INSERT INTO member (username,password,email,salt )
VALUES ( '$username', '$password', '$email', '$salt' )";

Answer 3

You are not inserting values to all the columns specified in the query.

In your query

$query = "INSERT INTO member (id, username,fname,lname,email, password, salt )
VALUES ( '$username', '$password', '$email', '$salt' )";

You are specifying 7 columns and only 4 values .So either add more values or remove unnecessary columns specified in the query like

$query = "INSERT INTO member (username, password,email, salt )
VALUES ( '$username', '$password', '$email', '$salt' )";

OR

$query = "INSERT INTO member (id, username,fname,lname,email, password, salt )
VALUES ('$id', '$username','$fname','$lname','$email', '$password', '$salt' )";
