    Re-populating a form if errors

    Hello,

    I am learning php. I have created a simple Web page with a form.
    After receing the POST request, I do some error checking. In case of
    errors, I would like to re-post the page, but with the current values
    for each field.

    I have organized my files like this:
    1) Webpage with the form (all in html, form action points to a php
    file)
    2) php file that receives the request.

    Is there a simple way to accomplish this?

      it is simpler to put everything in one php file and checking
      whether the $_POST array is not empty.

      you can keep your values with a construction like this:

      <input name="author" <?php if (isset($_POST['author']))
      {echo " value=$_POST['author']";}?>>

          when you reload the page in the input there is the option value so you
          would do:

          <input ..... value=<? echo $test; ?> />

          hope this is right :p

              Do it all in one file, for example parse_my_form.p hp:


              <?php

              $str_name = !empty($_POST['name']) ? $_POST['name'] : "";
              $str_age = !empty($_POST['age']) ? $_POST['age'] : "";
              $str_error = "";

              if($str_name == "" or $str_age == "")
              $str_error = "<p>Error parsing form</p>";
              else
              header("Locatio n: http://mywebsite.com/form_submission _ok.php");
              ?>

              <html>
              <head>
              <title>Fill in the boxes!</title>
              </head>

              <body>

              <?php echo $str_error ?>

              <form name="form1" action="parse_m y_form.php" method="post">

              <input name="name" type="text">
              <input name="age" type="text">
              <input type="submit">

              </form>


              </body>
              </html>

                  The super lazy way to do it

                  header("HTTP/1.0 204 No Content");
                  exit();

                      Ooops... change these lines:

                      <input name="name" type="text">
                      <input name="age" type="text">

                      To this:

                      <input name="name" type="text" value="<?php echo $str_name ?>">
                      <input name="age" type="text" value="<?php echo $str_age ?>">
