What are the potential pitfalls of using multiple submit buttons in a PHP form?

One potential pitfall of using multiple submit buttons in a PHP form is that it can lead to ambiguity in determining which button was clicked and therefore which action to take. To solve this issue, you can give each submit button a unique name and check which button was clicked based on its name in the PHP script that processes the form submission. 

<form method="post" action="process_form.php">
  <input type="submit" name="submit1" value="Submit 1">
  <input type="submit" name="submit2" value="Submit 2">
</form>
```

```php
<?php
if(isset($_POST['submit1'])){
  // Process form submission for Submit 1
} elseif(isset($_POST['submit2'])){
  // Process form submission for Submit 2
} else {
  // Handle case where no submit button was clicked
}
?>
