What is the potential issue with the PHP code provided in the forum thread related to Ajax and PHP?

The potential issue with the PHP code provided in the forum thread related to Ajax and PHP is that it is vulnerable to SQL injection attacks. To solve this issue, you should use prepared statements or parameterized queries to safely execute SQL queries in PHP. 

// Original vulnerable code
$connection = mysqli_connect("localhost", "username", "password", "database");
$name = $_POST['name'];
$query = "SELECT * FROM users WHERE name = '$name'";
$result = mysqli_query($connection, $query);

// Fixed code using prepared statements
$connection = mysqli_connect("localhost", "username", "password", "database");
$name = $_POST['name'];
$query = "SELECT * FROM users WHERE name = ?";
$stmt = mysqli_prepare($connection, $query);
mysqli_stmt_bind_param($stmt, "s", $name);
mysqli_stmt_execute($stmt);
$result = mysqli_stmt_get_result($stmt);
