I just started learning php and mysql and i might already be way ahead of myself. The thing i would like to create is a webpage where ppl can sign up for an event, so far so good, the form to submit their first name, last name, age and email adress is working and its actually sending te information to the database.
Next thing i want to create is a page where i can display all the database records submitted (except for the email adress). This is also working, but I wanted to play around with dynamic urls.
When i visit my page http://www.example.com/ppl.php?id=1 i get the information of the first database record displayed but i also wanted to see if i could get this to work with names instead of ids so i tried to edit my code and use http://www.example.com/ppl.php?name=john this does only return an error and however there are a few people called john in the database no records are displayed.
So i would like to know if what i want is actually possible and how do i get this to work with my current code.

<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "event";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$id = $_GET['id'];
$firstname = 'firstname';
$lastname = 'lastname';
$age = 'age';
$sql = "SELECT * FROM people WHERE id = $id";
$result = $conn->query($sql);
echo "<table id='display' width='600' align='center'>";
echo"<tr><td> Firstname</td> <td> Lastname</td> <td> Age</td>";
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo"<tr><td width='33%'> $row[$firstname]</td> <td width='33%'> $row[$lastname]</td> <td width='33%'> $row[$age] cm</td></tr>";
}
} else {
echo "0 results";
}
$conn->close();
?>
