php form

[dick220369]

i have the following form which is self referencing meaning that when the details are filled in and submitted the page reloads. i have been asked as part of a uni assignment to implement php code to make the form disappear or be hidden on the page when the page has reloaded and after the data has been submitted.

 

someone has suggested using

 

<?php

 

if (isset($_POST['submit'])) {

  // do form processing

}else {

  // display the form.

}

?>

 

but i don't know exactly where within my html to put this code. any suggestions?

 

 

i can't find any relevant material online that provides any where near a solution to this problem.

 

<form name="feedbackForm" method="post" action="<?php echo $_SERVER['PHP_SELF'];?>" onsubmit="return validation(this);" onsubmit="input.php">

        <table cellpadding="10px" width="100%">

          <tr>

            <td colspan="4" class="required">Items marked (required) must be filled in before the form can be submitted!!!!</td>

          </tr>

          <tr>

            <td>First Name:</td>

            <td><input type ="text" size ="30" maxlength ="40" name="firstname"></td>

            <td>Surname:</td>

            <td><input type="text" Size="30" maxlength="40" name="surname"></td>

          </tr>

          <tr>

            <td>E-mail:<br>(required)</td>

            <td><input type="text" Size="30" maxlength="40" name="email"></td>

            <td>Comments:<br>(required)</td>

            <td><textarea rows="5" cols="50" name="comments"></textarea></td>

          </tr>

          <tr>

            <td colspan="2"><input type="submit" value="Submit"></td>

            <td colspan="2"><input type="reset" value="Reset"></td>

          </tr>

          <tr>

            <td>The current time is:</td>

            <td id="thetime"></td>

          </tr>

          <tr>

            <td><?php echo "Session start time - server side:";?></td>

            <td><?php echo date('H:i');?></td>

          </tr>

          <tr>

            <td>Session start time - client side:</td>

          </tr>

        </table>

      </form>
