    returning to signup form

    hi

    i have a basic signup POST form, with php on the same page. how do i
    return to this page with all the entries still present, yet with a
    message at the top, for when the user enters one invalid entry?

    cheers

      I consider you will write to a database in the same php page and then
      redirect to another page

      Put this in the top of your page:

      if($Submit) { // Submit is the name of your submit button

      if(!$name || !$street) { # if for example name or street not filled in
      # generate errormessage
      if(!$name) {$err .= "Name not filled in";}
      if(!$street) {$err .= "Street not filled in";}
      } else {

      # alle input ok, here you can put your sql queries to interact
      with the database

      header("Locatio n: nextpage.php");
      exit;
      }

      }

          If you are posting the results to the page, then write them into the default
          values for the input elements. Something like;

          <html>
          <head>
          <!-- head stuff here -->
          </head>
          <body>

          <?php

          $defaultName = "Enter your name here"
          $defaultEmail = "Enter your email address here"
          $formError = false;

          if($_POST['update'] == 1) {
          $name = $_POST['name'];
          $email = $_POST['email'];
          if(($name == "") || ($email == "")) {
          $formError = true;
          print("<p>Error on form.</p>");
          if($name == "") {
          print("<p>Pleas e enter a value for Name</p>");
          }
          else {
          $defaultName = $name;
          }
          if($email == "") {
          print("<p>Pleas e enter a value for Email Address</p>");
          }
          else {
          $defaultEmail = $email;
          }
          }
          else {
          print("<p>Thank s for your input!</p>");
          // write the form contents to your database, or whatever
          }
          }

          if ((!isset($updat e)) || ($formError)) {
          ?>

          <form action = "thispage.php?u pdate=1" method="post">
          <p>Name: <input type="text" name="name" value="<?=$defa ultName?>"></p>
          <p>Email Address: <input type="text" name="email"
          value="<?=$defa ultEmail?>"></p>
          <input type = "submit" name="submit" value="Submit">
          </form>
          <?
          }
          ?>

          </body>
          </html>

          .... Note: This is straight off the top of my head! Not tested or anything!

          Hope that helps,
          Nige
