How can hidden fields be utilized in PHP forms to address the problem of submitting data with the Enter key?

When submitting a form in PHP using the Enter key, the data may not be submitted correctly due to the default behavior of the Enter key triggering the first submit button in the form. To address this issue, hidden fields can be used to ensure that the desired data is submitted when the form is submitted using the Enter key. By placing hidden fields with the required data before the submit button in the form, the data will be included in the form submission regardless of which submit button is triggered.

<form method="post" action="submit.php">
    <input type="hidden" name="hidden_field1" value="data1">
    <input type="hidden" name="hidden_field2" value="data2">
    
    <input type="text" name="input_field">
    
    <input type="submit" name="submit_button1" value="Submit 1">
    <input type="submit" name="submit_button2" value="Submit 2">
</form>
