Different page for different users using PHP - php

Question

I want to know how I would get user 'McKenzie' to see his own unique page that he can manipulate and 'Wendy' to see her own page when she logs in.
I've created the login and the pages, connected them to a MySQL database given them ID's etc, so I can do all of this and I know about sessions etc. ;)
So can someone tell me how I would do this, would I have to make different pages for each separate user? I'm thinking something along the lines of
REGISTER PAGE:
Store data in database, get user ID and use "?pageid=1" to then take the user to the id based page.
But I'm not sure how I would make each page without making them manually, as you can imagine making a new page for each separate user would be a pain... and very inefficient. Any ideas?
And please show me an example with code, it would be GREATLY appreciated! Thank you all in advance!

Answer 1

My answer is assuming you want to create fully customizable user data with the added possibility of sharing the page between users (like a profile page). With that out of the way you can do this by creating one php page that searches the MySQL table by $_GET or $_POST data.
Ill expand this answer in to a couple of steps...
SQL Tables
The first thing you will need is your MySQL set-up, ill assume you have a basic set-up already done but I will go ahead and create a simple one.
The basic set-up will be the login data and the custom user data, you can view my set-up here.
php user page
The simplest way would be to get the requested user from the $_GET data. So to do this we would simply get the data and request the users information:
$requested_user = $_GET['id'];
$db = new PDO('mysql:host=localhost;dbname=testdb;charset=utf8', 'root', 'MyPassword');
try {
$stmt = $db->prepare("SELECT * FROM c_userpage WHERE id = ?");
$stmt->execute(array($requested_user));
$mydata = $stmt->fetch();
} catch (Exception $e) {
//error with mysql
die();
}
Now we can simply add the users data to the page!
echo "Hello! my name is {$mydata['username']}!\n";
echo "About Me: {$mydata['custom_data']}";
Sending users to their page
We can simply just use www.page.com/user.php?id=2 And this will request the data for the user with id=2
Extras
If you want to keep user pages private you can simply request the id with $_POST or $_SESSION and then check if the user is logged in!

Here's an example of what you could do:
<?php
if (!isset($_SESSION['user_id'])) && (!isset($_SESSION['user_name'])) {
echo '<p class="login">log in</p>';
//exit();
}
else {
$user_name = $_SESSION['user_name'];
echo('<p class="login">' . $user_name .'\'s page | Log out</p>');
}
?>
There's a lot more you could add, but this is just to generate information on whether they were logged in.. If the $_SESSION['user_id'] is set, you can then generate code based on that information. (note, you would need to create the $user_name or whatever variable, likely from an sql query)
