Question

I have a form that send information to a mysql db. Error messages and a confirmation appear to the right of the form in a seperate div so the form action needs to send the user to the same page. I am echoing the field the user types in in case they need to edit something based on the error message that appears. However, if the form is submitted correct, how could i make it so the php does not echo in the form?

<?php

$submit = filter_input(INPUT_POST, 'submit');
//form data
$fullname = filter_input(INPUT_POST, 'fullname');
$email = filter_input(INPUT_POST, 'email');
$business = filter_input(INPUT_POST, 'business');
$date = date("Y-m-d");

?> 

then after other html code….

  <div class="wrap">
      <div id="reg">

  <form action='register.php' method='POST'>
<table>
    <tr>
        <td>
        Your full name:
        </td>
        <td>
        <input type='text' name='fullname' value='<?php echo $fullname;?>'>
        }
        </td>

    </tr>
    <tr>
        <td>
        Your email:
        </td>
        <td>
        <input type='text' name='email' value='<?php echo $email;?>'>
        </td>

    </tr>

    <tr>
        <td>
        Your business:
        </td>
        <td>
        <input type='text' name='business' value='<?php echo $business;?>'>
        </td>

    </tr>






 </table>
 </br>
 <input type='submit' name='submit' value='Register'>

</form>
 </br>       

    </div>
    <?php
 if ($submit)
  {
    //open database
  $connect=mysql_connect("localhost","root","Ryweb1994");
  mysql_select_db("phapsy");


  //check for existence
if($fullname&&$business&&$business)
{

   $queryreg = mysql_query("INSERT INTO users VALUES                           ('','$fullname','$email','$business','$date')");
    echo ("<div id='message'><p>You have been registered! We will send you an email            with login information. Thank you for your interest in Phapsy!<p></div>");

   }
else echo "Please fill in <b>all</b> fields!";

   }


  ?>
    </div>
  </div>

Just wrap your form around with the $submit variable:

+ <?php if($submit) { ?>
 <div class="wrap">
  ... 
  <form action='register.php' method='POST'>
  ...
  </form>
</div>
+ <?php }; ?>

    <?php
 if ($submit)
  {
    //open database
  $connect=mysql_connect("localhost","root","Ryweb1994");
  mysql_select_db("phapsy");


  //check for existence
if($fullname&&$business&&$business)
{

   $queryreg = mysql_query("INSERT INTO users VALUES                           ('','$fullname','$email','$business','$date')");
    echo ("<div id='message'><p>You have been registered! We will send you an email            with login information. Thank you for your interest in Phapsy!<p></div>");

   }
else echo "Please fill in <b>all</b> fields!";

   }


  ?>
    </div>
  </div>
