[PHP] no-resubmit on reload/refresh
I have a form which is submitted by a POST action. After submitting, the same page (updated though) returns with the form. (It's a messageboard) Now when someone refreshes/reloads the page they get the question if they want to resubmit the form. I don't want that. You get double posts this way. I know it is possible to check the input for any duplicates, but for example this guestbook http://pub.alxnet.com/guestbook?id=120611 (hope the id works) does it differently and your browser does NOT if you wnat to resubmit, it just doesn't do it. Anyone knows how this works (HTTP header maybe?) cheerz Bolke

Javascript? (I know it's generally horrible, but it's good for this sort of
thing)
Stick this in your head.../head:
script language="JavaScript" type="text/javascript"!--Begin
var submitcount=0;
function jsCheck() {
if (submitcount == 0) {
submitcount++;
return true;
} else {
alert("This request has already been submitted, please wait
while it is processed.");
return false;
}
}
//End--/script
And call it from your form like this:
form name="myform" action="whatever" method="post" onSubmit="return
jsCheck()"
Voila.

That's not really what I want
http://pub.alxnet.com/guestbook?id=200
(this one works)
does it without.
On my page I am using a child window to reload the parent window
, so your solution can't be used unfortunately.

Re: [PHP] no-resubmit on reload/refresh
Well, I've had the same problems with an "Send SMS" routine and it caused
the message to get sent twice or more if the user refreshed.
I fixed this by adding the following logic:
If there are post-data, put this into a session variable (an array of
key=val) and reload the page.
if there are no post-data put the session-variable array into the current
scope again using a foreach loop, and then delete the session variable, so
data won't be processed again. Works like a charm, and doesn't include
javascript. Don't know if it's excactly right for you, so you might have to
modify it a bit.
(From memory only, might be typo's:)
snip
?
session_start();
session_register( pre_posted );
if (count( $HTTP_POST_VARS)=1) {
foreach( $HTTP_POST_VARS as $k=$v ) {
$pre_posted[$k] = $v;
}
header( "Location: $PHP_SELF" );
exit;
} elseif ( is_array( $pre_posted )) {
foreach( $pre_posted as $k=$v ) {
$$k = $v;
}
unset( $pre_posted );
}
echo "bYou posted: $Test/bbrWant to refresh?";
?
form method=post
input name='Test' value='test' size=20
input type=submit
/form
