if you are using session to check if the form is submitted, you might want to session_destroy it.

If I don't use session.. is there any way to do it?

How are you submitting the post and displaying the dowload link or etc?

How are you submitting the post and displaying the dowload link or etc?

Exactly.  What causes the download link to display?  Whatever that is, stop doing that after the first time.  We can't see your code.

I use a form to download button in the download page and when user click on that button the form has been submitted and display the download box on the same page. (download.php). after submitted the form it is display as long as the page open. I need to close it when a user click on browser's refresh button. that mean page should redirect to the download page.

if you were to press F5 or press the refresh button, it will resubmit the form but once you re-enter the url, i wont show it anymore.

 

what i would actually do is to set a cookie when the user press download then once the user is at the downloading page, clear the cookie.

 

the downloading will only be displayed if cookie is set.

I don't know if you need to be logged in to download, or not, but here is a simple solution (IMO).

 

- When the user clicks on the link, insert into the database either their user_id, or their ip address

- When you load the page, check to see if the value is in the database, if it is don't show it.

        - If you base it on IP address, you will probably only want to limit the last download to a certain period, due to dynamic IP addresses.

@The Little Guy this is the link for the site. i don't think you would require login cause i am able to access the site without any logins.

Thanks Dear...

 

Can I use session for my download page without login system.

[ZulfadlyAshBurn]

YES. remember to start the session first.

 

<?php
session_start();
?>

[thara]

[ZulfadlyAshBurn]

<?php
session_destroy();
?>

[thara]

anyway, what do you want the page to do?

[thara]

sorry sorry my dear. I will change it.

[thara]

Did you see my page? My problem is users click on download button a download box will display to download the songs. no problem it is ok. but problem is even after download the song that box still remaining on the page. when user refresh the page that box also display on the page then my downloaded amount also increment by 1. It is reason to insert false data in to my database. It is better if i can it disappear on the page when a user click on refresh button.. Is it possible to fix that problem...?????

[ZulfadlyAshBurn]

using cookie should help?

[ZulfadlyAshBurn]

change this line

 

if( isset( $_POST ['download'] ) && isset( $_POST ['download'] ) == 'Download') {

 

to this

 

if( isset( $_POST ['download'] ) && isset( $_POST ['download'] ) == 'Download' && isset($_COOKIE["downloaded"])) {
      
$expire=time()+60*60*24*30;
         setcookie("downloaded", "yes", $expire);

 

and anyway you haven't change the signature.

[thara]

Ok. dear

thank you very much..

 

I have changed the signature

[ZulfadlyAshBurn]

sorry pardon me, it should be this

 

if( isset( $_POST ['download'] ) && isset( $_POST ['download'] ) == 'Download' && !isset($_COOKIE["downloaded"])) {
      
$expire=time()+60*60*24*30;
         setcookie("downloaded", "yes", $expire);

[thara]

I replaced the coding as u said then that box disappeared from the page. Now when I click the download button to download a song that box is not display again. now it is never come. without that box we cant download a song. Now my download counting also not working... actually I need to do is that download box display once and after download a song it should be disappear...

 

Thanks again for your time.. 

[ZulfadlyAshBurn]

add this

 

<?php
if (!isset( $_POST[ 'submitted5' ])) { 
$expire=time()-60*60*24*30;
setcookie("downloaded", "",$expire);
}
?>

 

before this

<?php
if ( isset( $_POST[ 'submitted5' ])) {
