Here we will discuss about the checking of login id and password against the data in the signup table. This part of the code is given in the loginck.php file given inside the zip file which you can download at the end of this tutorial. You can go to part 1 of this script which displays the login form for the members to enter userid and password.
Here we have used the same plus_signup table we used in our php signup script tutorial so you can use all the files to develop a signup and login application.
We will use one line of SQL query to get the reply. We will be using select query to get the data from the table
"SELECT * FROM plus_signup WHERE userid='$userid' AND password = '$password'"
plus_signup is the table name, userid and password are the field names. This SQL statement will return us one record if member userid and password is there in our table. So we can use one if condition to process the script if the usrid and password is correct and is there in the table.
We are using userid and password variables in our sql statement and using that to get data from our member table, it is not safe to directly use them inside query. We will use pdo to sanitize the data before using them. Let us first collect them
The else condition if userid or password is not correct will display the message and ask the member to try again.
That's all for our member login script.
Using the session variable we can show other pages or redirect the members to different pages.
have tried d above codes and they are all working fine. great job. but how can i redirect different users to different pages customized for only each user. thanks

Sorry, the page you are looking for does not exist
What is the page name you are seeing at the top on address bar ? That page should be there. After login there is a welcome page , check that you just placed that page.
