Form with two submit buttons?

alanzhao

Hi, here is the problem, I have two buttons in a form named 'Submit' and 'Preview', code as follows:

<form method="POST" action="post">
  Name: <input type="text" name="name" size="20"><br>
  Email: <input type="text" name="email" size="20"><br>
  Message: <textarea name="message" height="5" width="80"></textarea><br>
  <input type="submit" value="Submit">
  <input type="submit" value="Preview">
</form>

I want to have my next script to recognize two different actions "submit" and "preview", but I don't want to do the following:

 .................
 <input type="submit" name="action" value="Submit">
 <input type="submit" name="action" value="Preview">

because I allow my users to modify the template, thus, the buttons' name too, so my script won't recoginze the value if

  // what if button's value change to "Sent" or other language, this script won't work.
  if ($_POST['action'] == "Submit") {
  // .....
  }
  if ($_POST['action'] == "Preview") {
  // ....
  }

Any ideas, thanks:rolleyes:

then why not just name them "submit" and "preview", then process according to whether $POST['submit'] or $POST['preview'] is set?

Yeah, don't let your users change the names, and just give them the names submit and preview.
It's a lot easier 😃
Boards like phpBB and InvisionBoard let you change the templates too, but when you change a buttonname, it won't work anymore..

This method works, as long as the user don't change the button value to "".

That is true.

But how is that a problem?
If you cannot prevent the user from setting the buttons to NULL values when they have different names, what's to stop them from using bogus or NULL values when you depend on the values alone?
