Re: [PHP] Refresh (F5) adds another SQL record.
If the user hits the back button and then the forward, it sometimes
resubmits the form.
This is why i initiated the session and ended it at the end of the data
processing page. If they happen to press forward, or back, it will still not
initiate the form unless they have actually visitied and submitted the form.

Re: [PHP] Refresh (F5) adds another SQL record.
I've found a way that works for me.
Using the START SESSION on the initial form, e.g.
and the using the code below in the processing form.
You can do a check if the user has already submitted the from by the initial
session that starts then he/she is on the submitting form. If it is already
set it can continue, else stop and redirect.
MAKE SURE to put the unset session at the end of the form.

Problem solved. If you take this approach, just make sure you build a proper queuing system or mark the mails you're processing as being processed in the DB. Otherwise you could end up with a situation where the system takes longer than 5 minutes to process the mails (it shouldn't, but you never know - maybe there's a rogue process or the mail queue is backed up or something) and then the PHP script starts at the beginning of those 50 mails again. It's an obvious error, but I've done it in an app where I thought "There's no way the process won't finish before the next cron job starts", and then it happened and I ended up sending a couple thousand SMS's out twice at cost to my client.

Why not just have the cron task itself run every 5 minutes? Every 5 minutes, hit a PHP script that will pull the next 50 messages to send and send them, then exit.

OK, then I'd stick to what you're doing - add the event to a queue (i.e. your database), and poll this at regular intervals. I don't think you need to worry about the number of emails sent per interval. Just let your PHP script generate the sendmail commands and the email-text to stdout, then pipe that to /bin/sh. The output generated by your script would look like this: sendmail -oi -r . < .

[PHP] Cron php & refresh
I'm working on an application that includes e-mail notifications of certain events. Because the application will have hundreds or thousands of users, I've designed it so that e-mail notifications are saved to a MySQL table. Then a regular cron job runs a php page to select the data from the table, put it into a mail() command and mail. My original vision was to have the script do about 50 mails, then pause for a 5 seconds, do a meta refresh and run through another 50 and so on - with experimentation in numbers as necessary. This process was set up because I recall reading somewhere - perhaps the manual - that it is not a good thing to run too many php mail()s in succession. Also, I worry about php time-outs. If you know more about PHP and 'nix than I do, you already realise the fatal flaw here: meta refresh doesn't work on a cron job. Question: is there an alternative? I appreciate I could use sleep() after every 50 mails - but there would still be the time-out problem. I've searched the manual and via Google - but haven't found anything - possibly I am searching on the wrong terms. Your help will be much appreciated.

This is only of value if your db is getting hammered by requests.

Re: [PHP] Refresh (F5) adds another SQL record.
I did something pretty similar to this but not with an MD5 hash. I used a table which had just two fields, one autoincrement and another one a boolean. When doing a form, I added one record to this table and the ID I got from it is the one I sent in the form, the other field served to indicate that the ID had been used, as you mention. Later on I read about redirecting out of the update page, as Marek Kilimajer replied above and never bothered to do it again.

Re: [PHP] Refresh (F5) adds another SQL record.
Aren't we oversimplifying the issue assuming that the records inserted
cannot have everything duplicated but the autoincrement field?
If you are taking an order and the customer says 'hey, add another of this',
with the code below the system will reject it because it assumes that it is
a refresh and not a new addition to the order.
You are in the supermarket line and the teller is scaning your purchase for
the barcodes. You wouldn't be able to buy more than one of each! (I know
that you wouldn't use a browser in that environment, but for the purpose of
the database analysis, it just shows the point)
NO, some tables do have records which are basically duplicate of one another
except for the autoincrement field, and those cannot be checked this way.
And, besides, as mentioned elsewhere in this thread (myself included) there
are easier ways which do not even involve database access.

Or, in general, redirect to any page as soon as you made the insert. It can
be back to the begining or to a confirmation page, so the user gets a
feedback of what has just been done. The point is, don't show the
confirmation or the new input form right in the same page as you did the
insert, redirect to it in some way.
I use to process my data in a single form per operation. I make each page
like this:
if ($_REQUEST['confirm'] == 'true') {
// show the confirmation of the last operation
}
if ($_REQUEST['submit'] == 'Save') {
// do the insert here
header('Location: http://yourserver.com/form.php?confirm=true');
}
// here, show the input form which will show either for the first time or
after the confirmation
// which ends with:
You might add to the redirect header some more arguments to be more explicit
about what is it that you are confirming. Anyway, the point is that the
browser will store the redirected-to address with all its arguments, not the
one with the form data, so, a refresh will give you the confirmation page,
not the insert one.

You should see a message from your browser that data is being reposted.
I looked for such a message and the only thing I can find is as follows:
1) _SERVER['HTTP_ACCEPT'] and _ENV['HTTP_ACCEPT'] and change to "*/*", but I
don't know if that is the case for all browsers, do you know?
2) _SERVER['REDIRECT_UNIQUE_ID'] and _ENV['REDIRECT_UNIQUE_ID'],
_SERVER['REMOTE_PORT'] and _ENV['REMOTE_PORT'], _SERVER['UNIQUE_ID'] and
_ENV['UNIQUE_ID'] change, but I don't think the values are predictable,
especially between browsers.
Do you know of a specific message to look for and is that message the same
for all browsers?
that's a message the user (using the browser) gets from the browser.
Unless you use GET method, but you should really use POST method for
forms that change state on the server.

The used MD5 hash tells you they are re-submitting the exact same form. Now, if the real problem is that the user has a fresh new form, and fills in the same data again by hand, then there are only two possibilities: 1. In the real world, they actually NEED two of the "same" thing in the database, and your application should allow it. 2. In the real world, users are likely to lose track of where they are in their data entry, and you need to provide them the context to help avoid that.

I thought by this time this problem would have had a standard solution. It
would be nice if PHP had a function like refreshed() so one could do ... if
(!refreshed()) { ... } ..., but I guess not.
Thanks for your input.

I looked for such a message and the only thing I can find is as follows:
1) _SERVER['HTTP_ACCEPT'] and _ENV['HTTP_ACCEPT'] and change to "*/*", but I
don't know if that is the case for all browsers, do you know?
2) _SERVER['REDIRECT_UNIQUE_ID'] and _ENV['REDIRECT_UNIQUE_ID'],
_SERVER['REMOTE_PORT'] and _ENV['REMOTE_PORT'], _SERVER['UNIQUE_ID'] and
_ENV['UNIQUE_ID'] change, but I don't think the values are predictable,
especially between browsers.
Do you know of a specific message to look for and is that message the same
for all browsers?

Re: [PHP] refresh page automaticly on PHP
or u can use this method from JS You could refresh the page in various ways 1- make a rerequest to the server to give u the same page again: using the PHP Header function. 2-using the html Header refresh tag 3-Java Script to reload the document Since the 1st and 2nd methods are discussed in the earlier posts I'll show another way of doing it by Javascript. This is useful if you're using a templated based markup rendering to replace ur Head JS tags or Body JS tags. Javascript redirection and reloading is done as the following: -if u want to reload the page after showing the page write this in body tag echo " location.reload();"; -if u want to reload the page the moment the page is requested then do this in the head tag echo " window.onload = location.reload(); "; Hope this is usefull.

Re: [PHP] refresh page automaticly on PHP
As the others said, this isn't a function of php, php is a server-side script and a refresh is on the client side. A meta-refresh tag is fine depending on how reliable you want your refresh to be as it'll stop working after a day or so. If you need it to refresh forever you'll need to use javascript.

The common solution for this is a "middle-man" technique. The middle-man is a PHP page that hanldes the form submission, sends the email, submits in the database, etc, and then forwards to another page using header().

You can do it with a header. I think something this simple will work:
header("Refresh: 120");
or in the area:
print "\n";
If you want to refresh to an explicit URL:
header("Refresh: 120; URL=http://...";);
print "http://...\";>\n";

[PHP] refresh parent window after submit of child
Hi, I have an "expiry_date" field on a webpage, if the client wants to edit it he clicks on the "Edit" link and a small window pops up with the current expiry date, after he changes it and hits submit its changing it properly in the DB...but the parent window still shows the old expiry date... I have seen many pages on the net where after the child window gets submitted the parent refreshes...any idea how this is done? is it with PHP headers or just javascript? or a combination? (Please note: I have found a pure javascript solution via google but want to know if this can be done in any other way) I would prefer a pure php solution as I dont know if JS will be on on the clients machine.

It sounds like you may want to set the page to not be cached. Here's
what I use to prevent pages from being cached:
function noCacheHeaders() {
header('Expires: Tue, 1 Jan 1980 12:00:00 GMT');
header('Last-Modified: ' . gmdate('D, d M Y H:i:s') . ' GMT');
header('Cache-Control: no-store, no-cache, must-revalidate,
post-check=0, pre-check=0, no-transform');
header('Pragma: no-cache');
}
This should prevent proxies, browsers, etc from caching your pages.

[PHP] refresh page (might be 0t)
Hey, Have run into a little problem...any help appreciated. Heres what I am doing: I give the client a control panel where he can add,edit and delete accounts, after each of the actions I have a link back to the index page of the contol panel...problem is, unless he presses the refresh button it shows him the same cached content. How do i force the browser to display the new updated accounts after and edit or the new list of accounts after a delete? I KNOW php is server side and this is a browser issue...but maybe this can be done with headers or something?

The problem is that you're only printing the list if there has been no
editing of the database, when in actual fact you want to print the
list regardless.
Why not just remove this part?

Re: [PHP] Refresh Error
Does your explorer ask you if you want to resend the information? It
does. You post your form once again. If you don't want this to happen,
use header("Location: http://yourserver/your_form_page.php";); redirect.

Re: [PHP] Refresh a frame based on a condition in another frame?
Hi, Thanks for the response, I'll try to explain better: I have 2 frames: a Menu and a Content frame. I have 2 menu's: one for support and one for sales If the content frame displays a support article, the support menu should be displayed. If the content frame displays a sales article, the sales menu should be displayed. If the sales menu is already displayed, I don't want it to be refreshed, because it's not necessary. It's already there! So, based on a condition in the Content frame (evaluated by content.php) I want to refresh (or not) the of the menu frame (controlled by menu.php). I hope this is more clear.

Re: [PHP] Refresh PHP
PHP session functions and $_SESSION work kind of funny with Internet
Explorer while this problem rarely happen in 3rd party browser due to the
bad design of Internet Explorer... It's a microsoft problem. I have this
similiar problem with Internet Explorer. The workaround to the problem I
have is to eliminate the use of session_destroy(). Someone anyone login, a
new session token will be created anyway. Shockingly, when going from one
webpage to another, Internet Explorer sometime grab a wrong session token.

Ralph,
Before anything, I would like to thank you for the time you are spending
with my problem!
Ok. I changed using $_SESSION and the problem still happens. I printed both,
$_SESSION and $HTTP_SESSION_VARS and they are the same... not the current
user, but the last logged. It's funny that in the next page, after login, if
I print $_SESSION or $HTTP_SESSION_VARS they are right, but when I call
another page (using a link), like some report, it appears the wrong user.
All pages has the same header, setting no cache...
any ideas?
Thank you

RE: [PHP] Refresh PHP
How about:
if($_GET['url_variable'] != $url_variable){
$url_variable = $_GET['url_variable'];
session_register('url_variable')
}

Hello Ralph,
Actually, after calling session_destroy() I reset those variables
assigning
an empty value like you said. But it still doesn't work. I did a test
after
destroying session variables, printing them. They are empty.
Another weird thing is that when a login as "joao" them logoff, exclude
IE
cache, going in Tools >> Internet Option..., and login again with
another
user, this way the variable are printed correctly.
It happens in any windows version (95,98,ME,2K,XP) using IE 6.0 and
Netscape
7.

Hi Everyone, My user has reported a problem when he loads a page. The page grabs data from MSSQL and displays this on the screen. However, it is not updated.
