What are the potential pitfalls of using multiple submit buttons in a form to update individual rows in PHP?

Using multiple submit buttons in a form to update individual rows in PHP can lead to confusion and potential errors, as it may be difficult to track which button was clicked and which row should be updated. To solve this issue, you can use hidden input fields to store the row identifier and determine which row to update based on the value of the hidden field when a submit button is clicked. 

<form method="post" action="update.php">
    <input type="hidden" name="row_id" value="1">
    <input type="text" name="data">
    <button type="submit" name="submit_row_1">Update Row 1</button>
</form>

<form method="post" action="update.php">
    <input type="hidden" name="row_id" value="2">
    <input type="text" name="data">
    <button type="submit" name="submit_row_2">Update Row 2</button>
</form>

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $row_id = $_POST['row_id'];
    $data = $_POST['data'];
    
    // Update the row in the database based on $row_id and $data
}
?>
