    Stopping blank form fields being submitted.

    I have created a form (below)

    How do I stop it redirecting to another page (productsearchr esults.php) when
    form is submitted if both the fields are blank?

    Any help appreciated.

    Batezz


    <?php
    $redirect = "/Product/Productsearchre sults.php";
    if( empty($CityTown ) && empty($County)) {$redirect="";}

    ?>


    <body>
    <form action="../Product/$redirect" method="post" name="location search"
    id="location search">
    <p>Location search</p>
    <p>
    <label>City/Town
    <input name="CityTown" type="text" id="CityTown" />
    </label>
    </p>
    <p>
    <label>County
    <input name="County" type="text" id="County" />
    </label>
    </p>
    <p>
    <label>
    <input type="submit" name="Submit" value="Search" />
    </label>
    <label> </label>
    </p>
    </form>
    </body>

      If you want to stop a form to be submitted, then you have to use
      javascript. Use search engine to check for "javascript form
      validation" or similar phrases. You don’t have to know too much
      about javascript usually, as you can cut and paste from code examples.

          <?php
          [filter for valid chars in both variables]
          if(($_POST['CityTown'] == "") && ($_POST['County'] == ""))
          {
          ?>
          [FORM]
          <?php
          ) else (
          [REDIRECT]
          }
          ?>

              Technically, "to stop it being submitted". However, to stop the
              re-direct being actioned when J(ava)script is off, or not available,
              it needs to be backed up with server-side validation.

                  The best way to do this (in my opinion) is to submit to $PHP_SELF --
                  in your form make the value of each field $_POST['thename'] -- then
                  you can keep the submitted info in the form, and do a
                  if(!isset($_POS T['name'])){echo "enter the info dummy";} -- this also
                  allows you to go a step further and do email verification etc..
