What are the advantages and disadvantages of using hidden fields to pass form data between pages in PHP?

Using hidden fields to pass form data between pages in PHP can be a convenient way to transfer information without the need for complex session management. However, hidden fields can potentially expose sensitive data to users who inspect the page source. Additionally, hidden fields can increase the size of the form and may not be the most secure method of transferring data. 

<form action="page2.php" method="post">
    <input type="hidden" name="data" value="example_data">
    <button type="submit">Submit</button>
</form>
