What is the common mistake in the PHP code provided for updating the background color in the database?

The common mistake in the PHP code provided for updating the background color in the database is the incorrect use of the UPDATE statement. The code is missing the SET keyword to specify the columns to be updated. To solve this issue, the code needs to be modified to include the SET keyword followed by the column name and the new value. 

// Incorrect code
$color = $_POST['color'];
$id = $_POST['id'];

$sql = "UPDATE users WHERE id = $id background_color = '$color'";

// Corrected code
$color = $_POST['color'];
$id = $_POST['id'];

$sql = "UPDATE users SET background_color = '$color' WHERE id = $id";

// Execute the SQL query to update the background color in the database
// Add your database connection and query execution code here
