php - Submit html form without refresh or jquery -


i making webpage has html form in , php code process form data. want make doesnt refresh page after each button press , save data file? how go doing this?

here code:

<html>     <head>     </head>      <body>          <form method="post" action="out.php">              <input type="submit" name="foo" value="a" />             <input type="submit" name="foo" value="b" />             <input type="submit" name="foo" value="c" />             <input type="submit" name="foo" value="d" />             <input type="submit" name="foo" value="e" />             <input type="submit" name="foo" value="f" />             <input type="submit" name="foo" value="g" />          </form>          <?php         $name = $_post['foo'];         $fp = fopen("formdata.txt", "w");         fwrite($fp, "");         $savestring = $name;         fwrite($fp, $savestring);         fclose($fp);         ?>      </body> </html>

if you're avoiding javascript altogether, can target hidden iframe.

css:

iframe.hidden{ display:none }

html:

<iframe name="iframe" width="0" height="0" tabindex="-1" class="hidden"></iframe> <form method="post" action="out.php" target="iframe">...

however, you're better off using javascript ensure data has submitted properly. if user's session has expired? if internet connection unstable? how know data validated ok?
