Form per contatti professionale

[balestra_romani]

Bene... io incomincio se poi qualcuno fosse interessato e volesse contribuire é ben accetto... lo scopo e creare un form ben fatto e lasciare il contenuto di questa discussione per chi fosse interessato...

io ho recuperato questo esempio:

form.php

<form method="post" action="invia.php"><INPUT NAME="op" TYPE="hidden" VALUE="send">
  <table>
    <tr>
      <td>

Nome:</p></td>
      <td>
        <input name="name" type="text" size="30" maxlength="150">
      </td>
    </tr>
      <tr>
      <td>

E-mail:</p></td>
      <td>
        <input name="email" type="text" size="30" maxlength="150">
      </td>
    </tr>
    <tr>
      <td valign="top">

Messaggio:</p></td>
      <td><textarea name="message" cols="40" rows="6"></textarea></td>
    </tr>
    <tr><td></td> <td><input name="submit" type="submit" value="Invia"></td></tr>
  </table>
</form> 

action.php
