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

Javascript? (I know it's generally horrible, but it's good for this sort

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;

And call it from your form like this:

jsCheck()"
Voila.

Subject: [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?)

Re: [PHP] deleting cart items on session expire
Well, why not store the item's in the session-var? When the session dies because of timeout or user-intervention, the items dissapear too. Or store a timestamp along with the items, and refresh the timestamps as needed. Then put in a cron-job to delete out-of-date items left in the DB at regular intervals. -J 17.02.01 02:29:04, Joseph H Blythe [EMAIL PROTECTED] wrote: hey all, I was wondering how one would suggest removing items from a cart system once the session lifetime has expired.

Re: [PHP] Variable quantity chooser.
The slider control is not a regular html-form-object. (on Windows you can see one in the recycle-bin properties). If you want to, or need to, i guess you can use an active-x control og make a javascript to do it. I wouldn't reccomend either... However if you need to set a not so spesific number you can use multiple radiobuttons or something like that. I made one just in this case to see if it's useful. One never know what will come in handy later on :-) It's not excatly what you wanted, but you might want to take a look at www.omnimedia.no/slider.php3 for the source and a quick try.

Subject: [PHP] db connection error: need help badly
Quoting from my previous message. I think my exact question is that when I
add a new db on to db server, How do I set up username and password to
access that db? All I did was just run the query at "mysql" database to
insert Host, username at "user" table ( left password blank)and gave all
privileges as Y. And insert Host, User at "db" table with Y privileges as
well.
And what I added to the Host field on both tables is 216.122.146.146 (
which
is the same IP susing at the code to establish db connection below.). But
the IP for my db server is 216.122.146.147.
Then I write "mysqladmin reload " .
It still did not work. Somone told me that what added into the host
field
on bothe table ( db and user) should be where I connect from, which in
this
case should be 216.122.146.146, not the other IP, And the host IP in the
db
connection sniplet should be the same too, right?
So is there anything I miss here?

Re: [PHP] multple select forms... going to hit my head against a wall ..
If you don't put it in a session var, and need to transport it you can use
f. x. :
input type=hidden name='user_selections' value='?=implode( "||",
$select )?'
This puts double pipe-chars between the array variables. You can later (when
u need to use the vars again) use: $select = explode( "||",
$user_selections );
to put it into an array again.

Re: [PHP] javascript and php
In general: We made a script which did this, however a bit limited because of the client/server-problems mentioned. The script is part of a registration-form, and pick out a city based on the zip entered. We didn't want the list of zipcodes and cities in JS since it would be quite huge. Don't remember the excacts but in general: (simplified model) form name=oFrm input name=zip onBlur='fetch();'input name=city /form Fetch() is a function that opens a new pop-up window at 50x50px, and set the url-property of this window using JS (ex:) var strURL = "find_city.php?zip=" + document.oFrm.zip.value; The find_city.php script recieves the zip in a get-var, and can connect to mysql and retrieve the city etc. and closes itself. find_city then outputs JS (ex): script opener.document.oFrm.city.value = "$the_right_city"; self.close(); /script The "drawbacks" here is a window flashing a short second or so... You can make this thing run queries or whatever... Wrote the above from memory, so the syntax might be a bit of, but the flow is the same. have a nice day! -Jrg V.
