Takto je definovaný formulár (je tu len jedno tlačítko):

<form name="send" id="send" method="post">
        <input type="hidden" name="language" id="language">
</form>
<table border=0 cellpading=0 cellspacing=0 bordercolor=gray>
  <tr>
    <td><center>
	  <?
        echo"<img src='".$path."images/en0.gif' border='0'><br><br>"
	  ?>
    </center></td>
  </tr>
  <tr>
    <td><center>
	  <?
        echo"<input name=\"en_\" type=\"button\" value=\"Anglicky\" onclick=\"send.language.value = this.name; send.submit();\" >"  
	  ?>
    </center></td>
  </tr>
</table>
