$_SERVER help

i8badhaggis · January 8, 2010

so this is really weird. I can't quite figure out why it doesn't work. I am doing the following:

$_SESSION['loginPage'] = $_SERVER['REQUEST_URI']; // = /people-search

I then begin to output the page.

After a little bit of html tags outputted the variable changes to /page-not-found instead which is the name of my page that people are sent to on default and I can't figure out why it sends me there.

it works only if I remove anything like <td id="content">

it seems to work without those being outputted but of course I want / need to have those in there. at this point I think I'm going to have to simply add divs inside those tds like <td><div id="content"> instead.

is there some reason it shouldn't like those to be outputted?

Sounds weird. Post some actual code.

//so here's where I set the variable
if($pageTitle != "login"){

//a bunch of outputting

after I run this I look at my session on another page... it should still say the correct page and doesn't always

<td id="header"> can not be <td id="head"> it won't work then

<td id="m"> can not be <td id="menu"> again it won't work then

I have no idea why it wouldn't like those

simshaun · January 8, 2010

Still looking at your code, but I don't see you calling session_start() at the top.

i8badhaggis · January 8, 2010

sorry there is a lot of code above it. I can assure you session_start() has been called properly.

it's really weird still... it doesn't like those two <td id="header"> or <td id="menu">

simshaun · January 8, 2010

Post the entire thing. I don't really see anything wrong with what you posted.

Also, when you attempt to view the sesion value on another page, are you sure the value isnt being changed on that page?

ok so here is everything

let me know if you need anything more. I just don't understand how a variable in session can be modified simply by not outputting a <td> tag.

if I change it from <td id="head or header"> to <td> it works

I don't understand

here's my page

now if I uncomment the td tags the variable is changed. keep them commented and it works.

simshaun · January 8, 2010

No offense, but what a mess!

PHP does not care about the HTML you output, but there are limitations for things such as headers and sessions.

One such limitation is that you may not have any output before sending a header or starting a session. (There is a workaround for this, but out of scope of the thread.)

Without being able to actually run your code, I can't say for sure whether that is the problem or not. Its either that, or a flaw in your logic. Like I said, PHP does not care whether you have <td> or <td id="header">.

All I can say is,

1. Verify $_SESSION["loginRedirectPage"] has the correct value directly after setting it.

2. Verify it has the correct value at other key points on the same page that it is set to ensure you are not unintentionally modifying it.

3. Verify it has the correct value at the very beginning of the login page.

4. Verify it has the correct value at key points of the login page, again to make sure you are not unintentionally modifying it.

i8badhaggis · January 8, 2010

ok here's the weird part. you can see where I set it.

if I var_dump it at the very end. the absolutely last thing to be called is that dump. it's the correct value. if I open up the following file right afterwards

<?php

session_start();

var_dump($_SESSION);

?>

it's different. why?

simshaun · January 8, 2010

Give me a before and after dump of $_SESSION (with only the relevant information).

i8badhaggis · January 8, 2010

actually here

here is a straight page

<?php

session_start();

$_SESSION["loginRedirectPage"] = $_SERVER['REQUEST_URI'];

?>

<?php 

var_dump($_SESSION);

?>

I open it in that simple page above

it's all based on those two td tags still

set them to simply normal <td> and it all works fine

set them to anything else and it breaks

i8badhaggis · January 8, 2010

result directly after running it

array(2) { ["initiated"]=> bool(true) ["loginRedirectPage"]=> string(6) "/z.php" }

result at the end of the page

array(2) { ["initiated"]=> bool(true) ["loginRedirectPage"]=> string(6) "/z.php" }

result on the next page with the following code

<?php

session_start();

var_dump($_SESSION);

?>

array(4) { ["initiated"]=> bool(true) ["loginRedirectPage"]=> string(15) "/page-not-found" ["application"]=> NULL ["request"]=> NULL }

simshaun · January 8, 2010

Are you using any kind of auto prepend or auto loading?

If you load a debug page that contains ONLY

<?php

session_start();

var_dump($_SESSION);

?>

and nothing else, something has got to be running beforehand to change the variables.

i8badhaggis · January 8, 2010

I use the following .htaccess

RewriteEngine on

Options All -Indexes

#RewriteRule ^maintenance$ ErrorHandling/redirectPages/maintenance.php
#RewriteRule ^dev/complicate/the/url/maintenance$ dev/complicate/the/url/ErrorHandling/redirectPages/maintenance.php

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !^caller.php$
RewriteCond %{REQUEST_FILENAME} !^page-machine.php$
RewriteRule ^(.*)$ caller.php [L]

to get to the file caller.php

if put a die("t"); or even just a var_dump("t"); at the beginning of caller.php that test page and display page work properly however t is never displayed

simshaun · January 8, 2010

Do this then,

Create two new pages:

testinit.php

<?php
session_start();
$_SESSION['redirectTo'] = $_SERVER['REQUEST_URI'];

header('Location: testview.php');
exit;

testview.php

<?php
session_start();
var_dump($_SESSION);

Run testinit.php and see if it displays "testinit.php" as expected.

i8badhaggis · January 8, 2010

array(2) { ["initiated"]=> bool(true) ["redirectTo"]=> string(13) "/testinit.php" }

yep that's what it should be.

I have another page

that does the following to destroy my session

which set the initiated index

<?php

session_start();

$_SESSION = array();

$_SESSION['initiated'] = true;

var_dump($_SESSION);

echo "Session destroyed";

?>

so. it worked properly

this leaves the question of what does my html do to it. cause I do not think that it could do that. what would an auto_append look like? cause I don't think I have anything like that

simshaun · January 8, 2010

Ok so its definitely something to do with your logic in either the caller.php or pagemachine.php.

I've got to run out of the office, but in the meantime try spreading

echo 'short desc of where this line is at in your code: '. var_dump($_SESSION);

throughout those two files and find out where the session var is being changed to an unexpected value.

i8badhaggis · January 8, 2010

the problem with that idea is that I know that the variable survives the trip through my code in both of those files. at the very very absolute end it is still correct. but if I go to that session_display page it's different.

one thought I have is that perhaps $_SERVER['REQUEST_URI'] is changing... and maybe when I set my variable with it I'm simply giving it a pointer by mistake.

i8badhaggis · February 2, 2010

ok I can't freaking believe what the problem was. all my pages were looking for a favicon and since there was none my .htaccess interpreted it as a page name not a file. thus a page not found page and ugh... well at least I know the problem now
