What could be causing the issue where categories are not displayed when trying to list an item on an auction site in PHP?

The issue where categories are not displayed when trying to list an item on an auction site in PHP could be due to a problem with retrieving or displaying the category data from the database. To solve this, ensure that the category data is being queried correctly and that the retrieved data is being properly displayed in the frontend. 

// Assuming you have a database connection established

// Query to retrieve categories from the database
$query = "SELECT * FROM categories";
$result = mysqli_query($conn, $query);

// Display categories in a dropdown menu
echo "<select name='category'>";
while($row = mysqli_fetch_assoc($result)) {
    echo "<option value='" . $row['category_id'] . "'>" . $row['category_name'] . "</option>";
}
echo "</select>";
