Question

I have the following *code below, every time I refresh the page it asks me to send the form again. How do I avoid that, I don’t want to resend a form on a page refresh. Thanks in advance.

*CODE

<?php function make_user_feedback_form() {
    global $wpdb;
    global $current_user;


        $ufUserID = $current_user->ID;

        if ( 'POST' == $_SERVER['REQUEST_METHOD'] && !empty( $_POST['action'] ) && $_POST['action'] == 'updateFeedback' ) {
            $ufDataUpdate = $wpdb->insert( 'wp_user_feedback', array( 'date' => current_time('mysql'), 'responses' => $_POST["test"]) );
        }
        }?>
    <div id="form">
    <ol>
        <form method="post">
            <li><label for="test">Question 01</label><input type="text" id="datepicker" name="test" value="" /></li> <!-- the (name="test") value is what the ('responses' => $_POST["test"]) value is talking too -->

            <li><input name="submit" type="submit" id="submit" class="submit button" value="Send feedback" /></li>
            <?php wp_nonce_field( 'updateFeedback' ); ?>
            <input name="action" type="hidden" id="action" value="updateFeedback" />
        </form>
    </ol>
    </div>
    <?php 


add_action('the_content','make_user_feedback_form');
?>

After you have processed the form data and stored it in the database or worked with it in some way, reload the same page using:

header("location: thispage.php");

Doing this will destroy the POST data and allow the page to be refreshed without displaying the resubmit alert.
