What is the common mistake made in the PHP code provided regarding updating the "beiträge" field in the database?

The common mistake in the provided PHP code is that the SQL query is not properly updating the "beiträge" field in the database. The query is missing the SET keyword before specifying the field to update. To solve this issue, the query should be modified to include the SET keyword followed by the field and its new value. 

<?php
// Assuming $newBeitrag is the new value for the "beiträge" field
$newBeitrag = "Updated Beitrag Value";

// Connect to the database
$conn = new mysqli($servername, $username, $password, $dbname);

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

// Update the "beiträge" field in the database
$sql = "UPDATE tablename SET beiträge='$newBeitrag' WHERE id=1";

if ($conn->query($sql) === TRUE) {
    echo "Record updated successfully";
} else {
    echo "Error updating record: " . $conn->error;
}

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