返回最后插入值的ID SQL

Question

I'm inserting data into members table, after I've inserted it I want to get the userID of the information just inserted. Whats the best way about doing this ?

My php code

    //Insert info into database
    $sql = "INSERT INTO members (type, firstname, lastname, email, password, bio) VALUES ('$usertype', '$firstname', '$lastname', '$emailsighup', '$passwordsighnup', '$bio')";

        //Run a query to check if data has been inserted correctly.
        $records = mysqli_query($connect, $sql);

I did try this SQL but was getting errors

    $sql = "INSERT INTO members (type, firstname, lastname, email, password, bio) VALUES ('$usertype', '$firstname', '$lastname', '$emailsighup', '$passwordsighnup', '$bio')"; SELECT SCOPE_IDENTITY(userID);

Answer 1

Assuming $connect as the variable holding your connection information, which seems legit, you can get the value of the last id with:

$user_id = mysqli_insert_id($connect);

This is something you can do from the PHP MySQLi interface , rather than directly from SQL!
