I am a problem with I logout from my site. When I push log out link I send it to a new page with this script in this: <?php session_start(); session_unregister($SESSION); session_destroy(); unset($SESSION);?> In each page I have this other script #accesscontrol.php <? session_start(); if (session_is_registered("SESSION")!= FALSE ) # ya la sesion existe entonces la cargo { #Maybe I use after. } else {echo "<h1>Sorry...</h1>"; echo "<A href = "index.php"><H4> Login Univernet</H4> </A>"; session_destroy(); exit;}?> The problem is when I log out and press the back button I am back to the pages. Sometimes it tells me that page expired but if I reload the page everything is ok and all my "security" pages are available.

Browser History Problem
In some instances (after using forms) trying to go back through browser's history causes a 'Cannot find Server' error. Hitting 'refresh' then loads the page correctly. Example: After using the search funtion in upper right corner at http://tipstraders.com to search for 'F', then clicking on of the links. How can this be resolved?

"Warning: Page Has Expired" - How To Aviod When Using Browser Back Button?
In summary: I want to a form to submit information via a HTTP POST, however, when using Internet Explorer I want to be able to use the back button and all the information retained. Presently we get a "Page has expired" message. How can we avoid this? Full details: Having searched for postings on how to avoid the "Page has Expired" they are numerous, however, I have not found one that answers the question adequately. Hence this posting. One posting directed me to the following webpage: http://in.php.net/session_cache_limiter but I played around with "session_cache_limiter()" and it did not give the desired results. (It seem to make no difference). Also many people say to use HTTP GET instead but this is not an option in this case. Where can I find concise definitive information on how to avoid "Warning: Page has Expired" and allow the user to press the back button and see the form as it was before they submitted it?

Page History
on my website I allow users to enter the website as a guest or login, and if they continue as a guest they have the option to login on every page, the only problem is if they login they go to the login page after logging in they are directed to the welcome page again . i was wondering if there was a way for them to login and return to the previous page, i know if could create a login page for every page and redirect them to each relative page but that would just be so inefficient i was just wondering if there was a way to attach the page (filename) to a session or cookie etc.

Need To Remove History Of Last Page
I'm working on a web site for a domestic violence group and these groups always have an "escape" button, which is simply a link to another site. Whether I open this link in the same window, a new window or target="top", the back button will always return me to the domestic violence site, which is what we wat to avoid. Is this possible via PHP?

Page Appears Twice In The Browser's History
I've got a login include file which appears on every page of my site which when submitted POSTs to the current page, and the include makes the appropriate changes now the user has logged in. The problem is that if the user then clicks 'back' in their browser they get the same page again, so they end up having to click 'back' twice in order to return to the previous page.

Back Button On Your Browser
My question is based around back button on your browser . Currently I have a form that feeds it's information into a MySql database. I give my users the ability to add, edit, and delete entries. Because of this I use actions on my submit button, ( if action=edit) {blah blah blah} else blah blah If a users make and addition everything is fine, butif they press the back button, the action is carried out again. (because the action is in the url (www.blahhblah.com/form.php?action=add) this puts duplicate entries into the database, which is easy to fix, but annoying. Is there a way with PHP to force the timeout page everytime they try to re-enter the form from their back button?

Browser Back After POST
I got an annoying problem using the POST-method to send a form's data: I put a login-form on the page which is sent by the POST-method to itself. After that the content of the POST-variables will be checked (!empty($_SESSION['xyz'])) and the rest of the page included. In order to show some informations (e.g. "Welcome John Doe") and becoming independent of specific POSTs, the data is also written to SESSION-variables. Now if I go to another page (by link) and after that back to the login-page by the browser's "back"-button, it cannot be displayed ("The page cannot be displayed..."). Only if I actualize the page it is displayed regularly. I know that this problem doesn't appear by using the GET-method, but because of security reasons I have to use POST. So what can I do to fix that problem? I don't want to disable the browsers back-button (or use some JavaScript).

$HTTP_REFERER On Browser Back
I'm using HTTP_REFERER to see what pages are being looked at before a member of my site comes to my HOME page. HTTP_REFERER works perfectly if the previous pages viewed are linked to the HOME page and they use the link to get to it. However, if they type in the address of the HOME page into the browser or scroll backwards or forwards to the HOME page the HTTP_REFERER does not work. Any ideas on what I am doing wrong or what I can do?

Stop Browser Back
I am creating a user rating system and have done it all apart from one thing that is baffling me. Once the user has submitted the form how do I stop them from just hitting back and submitting it again? I have got a cookie system that stops them from re entering it going forward but this does not stop them just hitting the back button and voting again.

Sessions And Browser Back Button
I originaly wrote a script that passed variables from script to script via query strings. When I did that, the user was able to use the back button to go back to previous pages and change form inputs. Then I changed my scripts to use session variables to get rid of the long query strings. Now, when the user hits the back button: "Warning Page has Expired" is what they get. Why is that?

Unable To Use The Back Button On The Browser
On my site, which uses sessions to log in and track users, if the back button on the browser is used the page times out and says you have to hit the refresh button to refresh the page you were trying to get back to. Not very user friendly, anybody have any ideas why?? There is a function called do_authentication that is called at the top of every page to check the user has logged in and has the appropriate rights. I don't think it is to do with the sessions though as if you hit the refresh buttin on the page with the error you are allowed back to the page you were trying to get to?

Trapping The Browser Back Button
I'm working on a web application that consists of two PHP files. The first is intended to do all the display work based on SESSION variables. The second file processes all of the _GET and _POST data, sets the necessary SESSION data then redirects to the first page. This process seems to work well while operating the application, but fails miserably when the user uses the Back button on the browser. Since the application bases it's state on SESSION variables, the Back button has no effect at all.

Shopping Cart Navigation And Back Button Browser
I am building a shopping cart where the user adds items to his shopping cart and shippes some to himself and others to someone else as a gift. I do the following thing, First let the user fillout his info and I ask him to check which items does he want to send to himself. Once he hit submit button I do the following. 1) I process which poduct does he want to ship to himself. Then I remove those products from the shopping cart. 2) Then if he has items in his shopping cart remaining I display address form and checkboxes asking user to check all items that he want to ship to this address. then I repeat step 2 until the user has no more items in his shopping cart. when he has no items I will display billing page. Here is my problem if user hits back button in the browser and then enters submit button I have not items in the shoppingcart since I removed them from his shopping cart the first time he processed his form. So how do I deal with back button in the browser. I have no idea how to it when I have multiple forms.

Refresh (back?) Causing Browser To Resubmit Form
Ive got a form on my site where users are registering and paying for a service, which is submitted to a 3rd party site which takes care of the financial aspect and then forwarded to a confirmation screen on my page. It seems as if some users are hitting the back button and resubmitting the data, as they are being registered multiple times. What would be a good way to get around this, so they could not go back to the page where the form was submitted and therefore re register?

Pressing Browser Back Button - Form Filled Data Disappeared
When filling out a web form on a php page that is submitted to a search which lists the results based on the criteria provided (in the form), all works fine and as expected. However, when I press the back button to amend the form all of the search criteria data has gone and I have to fill it all out again if I want to do a similar search which is frustrating. (This does not actually happen in Firefox browser but most of my users will be using IE). How can I prevent this from happening? Previously I made a post about avoiding "Page has expired" and the conclusion I came to for that was not to use a "POST" which did the trick. But now I want to retain the data I input?

Log In Page That Goes Back To REFERRING Page
I am using the following code to initialise a session, depending on whether-or-not the users' log in attempt has been successful. if ($session_ok == "TRUE") { //open the session session_start(); //assign user details to session $_SESSION[txt_user] = $user_id; $_SESSION[user_pass] = $user_pass; $_SESSION[ses_state] = "TRUE"; header("Location: ../index.php"); } as you can see the script then refers back to my index.php page, after the session is ok'd. What I would like to do is change this so that is goes back to the referring page, instead of the index.php page, which requires the user to then navigate to their previous page again. I have attempted to use $HTTP_REFERER, although for me (on IE6) for some reason their is no value in the variable!

'Back' Page After Logout
I'm using HTTP authentication as my login mechanism, and I'm having problems with the logout. It appears to work (as in I get the right message when I've logged out) but pressing the 'Back' button gives me the information on the previous page as though I hadn't logged out at all. 1) Does $PHP_AUTH_USER not get cleared when a "401 Unauthorized" is encountered? 2) Is there any way to force the logout to apply to previous pages (I'm thinking using sessions or cookies perhaps), or do I have to get the user to close the browser window?

Posting Back To The Same Page
I have a website that uses user authentication. The login does a post back to itself to check set usernames and passwords. <?php echo $_SERVER['PHP_SELF']?> sample url: .../admin/login/index.php This is working on a linux box where the end of the php code sends the page off to a ccc.php page for access checking. So after logging in on the index.php page, you eventually get returned to admin/ccc.php. I reused the same code on a windows box and the .../admin/login/index.php takes me to .../admin/login/index.php/admin/login/index.php does anyone have a clue as to what might cause this?

Does 'Back' Reload The Page?
I notice that when I click the 'Back' button my previous script runs, i.e, all the php code runs (I previously thought that maybe the previous form displays without the code re-running). However, I do not get the expected value displayed on my form. After populating one element in formA with ཌྷ' (just any number) and submitting to formB (using POST ---> Redirect --> GET to avoid the 'expired from cache' message) I then click the 'Back' button and the 17 does not appear. In the code below, after clickng 'Back', I see as output from the echo statement that rb_value[0] is, infact, ཌྷ' but within the form, the text element named rb_value[0] displays as empty. Does anyone have suggestions why this might be? It might have to do with that I do not understand what the 'back' button does. Or maybe with my PRG (post - redirect - get) model. Here is part of the code: echo "rb_value[0]=".$rb_value[0]; //After clicking 'Back' I see that rb_value[0] is 17 if (isset($rb_value[0])) { $rb_val = $rb_value[0]; } else { $rb_val = 1; } $line.= "<td width="20%" valign="center" align="left"> "; // This element displays as empty instead of the expected 17 $line.= "<input type=text name="rb_value[0]" value="$rb_val" size="25" maxlength=25 </center> " $line.= "</td> ";

Back To Last Page Viewed
i was wondering if php is capable of doing the following and if so was hoping i could get some help doing it. i have a wordpress blog and change the content of the sidebar depending if the page being viewed is part of the blog (home, archive, search, or single post) or an actual seperate page (like the about, disclaimer etc). what i'd like is to have a link on the sidebar when viewing a page that says "back to blog" thats acts as a back button like in a browser, going back to the last page viewed. except what i want is for it to go back to any page that isnt a page, so basically the last blog page. um, does that make sense?

Page If Back Button
I have a php page which is a sign up page, once signup is finished the user is redirected to a new page. Sometimes (and it's rare) the user hit's the back button and then re-submits the form etc. I mean like I said it's rare but still bothers me, so on the last page I kill all the sessions. Which only works if the user hits the back button but the page is refreshed. So basically I want to know if it's possible that when the back button is hit to refresh a php page?

Ob_start() And Going Back To The Previous Page
1. How do I go back to the previous page using PHP? For example, I have a log-in process which validates username and password of members, and also retricts access to certain pages. So if a member goes into a page without logging in, the member will be presented with a form to log in. How can I make my script go back to the previous page they were trying to access prior to logging in? 2. What would happen if I use ob_start and ob_end_flush() on every page that I have? Would it affect loading time? Or would loading time be the same except that it would cache everything first? Isn't that suppose to make it appear that the page loads fast?

After selecting one of the options and going to the next page, it will display the results of that dropdown item as pulled from the database. If a user hits the back button, then selects a different option and hits "submit", what is listed is the results of the first selection AND the results of the second selection. Is there a way to either: 1. Refresh the page upon hitting the back button on the browser 2. upon hitting the back button, the browser forgets the selection previouslly made.

Then I click SUBMIT-button and I moved back to the page "A" #3.) I move to the page "B" by clicking link on page "A" #4.) I click "BACK"-button from browser #5.) I got "Warning: Page has Expired" I want that when I click BACK, I will be moved to the page "A" straightly without warning (of course then post-data can't get re-sent) Got any idea how in PHP I can prevent this warning?
