What are the potential pitfalls of using disabled input fields for editing data in PHP forms?

Using disabled input fields for editing data in PHP forms can be problematic because disabled fields do not submit their values when the form is submitted. This means that any data in disabled fields will not be updated in the database. To solve this issue, you can use hidden input fields to store the original values and use JavaScript to populate the disabled fields with the original values when the form is submitted.

<form method="post" action="update.php">
    <input type="hidden" name="original_field" value="<?php echo $original_value; ?>">
    <input type="text" name="editable_field" value="<?php echo $original_value; ?>" disabled>
    <input type="submit" value="Submit">
</form>
