What is the issue with updating the points in the "event1" table based on the "punkte" table in PHP?

The issue with updating the points in the "event1" table based on the "punkte" table in PHP is that you need to join the two tables in the SQL query to correctly update the points based on a specific condition. You can use a SQL query with a JOIN statement to update the points in the "event1" table based on the corresponding values in the "punkte" table. 

<?php
// Establish a connection to the database
$connection = new mysqli("localhost", "username", "password", "database");

// Check connection
if ($connection->connect_error) {
    die("Connection failed: " . $connection->connect_error);
}

// Update points in the "event1" table based on the "punkte" table
$sql = "UPDATE event1
        INNER JOIN punkte ON event1.id = punkte.id
        SET event1.points = punkte.points";

if ($connection->query($sql) === TRUE) {
    echo "Points updated successfully";
} else {
    echo "Error updating points: " . $connection->error;
}

// Close the connection
$connection->close();
?>
