Two Submit buttons on one form

Two Submit buttons on one form

am 12.01.2008 13:40:39 von ktstone2678

I have a basic shopping cart setup, currently the user clicks a button
to remove an item from the cart. The form action posts to itself in
order to update the item list.

Is it possible to have another button in the same form that posts to a
different location?

Please hold your comments if they're not constructive. I am aware of
the existence of Google, it just hasn't worked for me here.

Thanks

Yes, but you have to use javascript to change the form's action field value.

Javascript would work, but is unreliable.
Why not post to a page, that on the basis of said button, includes one or
the other script? Or a check at the top of the script that possible
decides to include another one and then exits?

I'll personally give buttons a name and make them all submit to self page
(see sample code on bottom). Then, check which name exists and act
accordingly: header('Location: ...') is your friend.

Make sure it's cross browser (IE has some problems if buttons are
type="image") and make sure of what happens when user hits the "enter" key.

Why would you want to do that? Why not just have the second submit
button post to the same location? Two submit buttons on the same
form can perform two different functions. I do this all the time.
The buttons have different value parameters, the php script picks up
on which one was clicked, and acts accordingly.

If you want two buttons in the same form to post to different
locations, you need javascript to modify the form URL. Not a good
idea, IMO, to rely on javascript when you don't have to.

Ideally that's would I would like to do. I need to do research on how
to accomplish that , but I think that's the best solution. Thanks for

I wanted to post the solution for anyone else who might stumble across
this thread, turns out to be very simple.



onClick="document.theform.action='first.htm';">
onClick="document.theform.action='second.htm';">

Which, depending on which statistic one believes, would not work for 5% =
- =

15% of your visitors. Also, If you're going to use javascript, ask in =

comp.lang.javascript for best practises.

I agree, PHP could handle it, just post the form to a single script which
will redirect to your desired location. In order to do this, I think you
could use CURL to re-submit the form data to the desired location, or just
think twice about it and hu.. I don't know.. ask the user to verify the data
he just entered and re-submit it itself =P. It's always worth it anyway !

---form.html---


....






---post-redirector.php---

# regen_form(): regenerates hidden form from array (usually $_POST)
function regen_form($data, $array_name=null) {
foreach( $data as $field => $value ) {
if( is_array($value) ) {
regen_form($value, $field);
} else {
if( isset($array_name) ) $field = sprintf('%s[%s]',
$array_name, $field);
echo ' ' . "\r\n";
}
}
}

if( isset($_POST['form_sent']) ) {
// stripslashes if hellish_quote_gpc on

// it's useless to sanitize your data here, as someone could always
// bypass the redirector to directly submit a custom form to the
// final script.

if ( isset($_POST['button1']) ) $location = 'location1.php';
elseif( isset($_POST['button2']) ) $location = 'location2.php';
else die('internal error #01 / hijack attempt');

ob_start();
ob_implicit_flush(false);
regen_form($_POST);
$form = ob_get_contents();
ob_clean();
}

?>



please verify your information:















The function is recursive and reproduces form-generated arrays so you don't
miss a thing; but you can just rewrite the form manually as well.

The output buffer is there by (good?) habit, not absolutely needed.


Of course, you can also pass the serialized & encoded $_POST via $_GET,
process it and then directly redirect the user or reload the page without
the $_GET (and thus don't process anything after reload) but I think you
might be limited in the size of the form.


Good luck ^^'.

That's no solution. You really don't want to do that.

Do it server-side.

Yep, and it fails for me and about 10-15& of the rest of the world
because we browse with javascript disabled.
