[SOLVED] Little help on sessions :P

[harsh00008]

Hey 

 

I after logging in in my login page i want a session to start so that it caries value through all the pages...

 

that means if the session is set then only someone can view a topic else he'll need to login 

 

any suggestions? 

 

I tried the session thing but it doesn't carry value to the other page 

 

any simple explanation/help would be great

You need session_start() on the top of every page that requires session use.

[harsh00008]

You need session_start() on the top of every page that requires session use.

 

That means wen i login..

 

for eg in my case...wen i input the login variables and hit the login button i get directed to the login.php page where it checks for the inputs and echoes that u r logged in..

 

 

so at that time i shall put session_start();

$_SESSION["logged"]=1 in the login.php if the account is verfied

and on all restricted page

session_start();

if($_SESSION==1)

{

blah blah codes

}

Else

{

Echo "you need to login to view this page";

};

 

???

 

 

and then session_start() on every page where i want the permission?? ???

 

and on logout.php put the session_destroy() code? :-?

[.josh]

yes.

 

[harsh00008]

It isn't working still 

 

the $_SESSION["logged"] value is not getting carried to the restricted page...

 

it remains 0 there not 1 on logging in

[.josh]

well that code you kinda sorta posted you did

 

if($_SESSION==1)

 

it's supposed to be

 

if($_SESSION["logged"]==1)

 

I just assumed you were showing some pseudo-code to get your point across but if that's what you really did..

[harsh00008]

yeah..forgot to type["logged"] there

 

but in the codes its ["logged"]

 

any reason or method to carry the $_SESSION["logged"] value to all the pages?  ???

[.josh]

It's really simple:

 

page1.php

<?php
   // must have this before any output and before you want to use session vars
   // must even be on the page where the session var is first set
   session_start();

   // example session var
   $_SESSION['logged'] = 1;

   // example to get to next page. can use header() or whatever who cares
   echo "<a href = 'page2.php'>page2</a>";
?>

 

page2.php

<?php
   session_start();

   // is there a session var called 'logged' and does it equal 1?
   if ($_SESSION['logged'] == 1) {
      echo "yay!";
   } else {
      echo "nay!";
   }
?>

 

If that's the basic format you have and you're sure everything is spelled right etc.. then perhaps you have cookies turned off in your browser?

[ShaunO]

If that doesn't work then sessions aren't turned on.

Or the web server doesn't have permission to write to the tmp directory in the php.ini (or it is pointing to an invalid path)

[harsh00008]

It Echoes "nay" in both the cases

 

even after u goto page2 via the a href function ,i.e., via page1> :(

 

I'm testing this project on my localhost

 

is it something related to this...that the browser cookies or the session function don't always work well on a local server  ???

[DeanWhitehouse]

make a page with

phpinfo();

 

on it , and check if sessions are on

[harsh00008]

 

Hey buddy is it off?

 

if yes how do i configure this stuff to make my sessions codes working? ???

[DeanWhitehouse]

As far as i can tell they are. Show the two pages code where the problem is

[harsh00008]

Hey buddy I tested these simple session codes to test if something was wrong in my codes

 

Where page1.php is

 

<?php

 

session_start();

$_SESSION["logged"]=1;

Echo "<a href=page2.php>Page2</a>";

 

?>

 

and page2.php is

 

<?php

 

session_start();

if($_SESSION["logged"]==1)

{

Echo "working";

}

Else

{

Echo "not working";

};

?>

 

 

 

and wen i access the page2 via the page1 link it still echoes not working!!!

[ShaunO]

My guess is that it can't write the session files to the folder session.save_path

Is PHP installed into C:\php? If so, there should be a sessions folder in there

If you change the session save path in the php.ini to the C:\php\sessions

 

If you are using IIS as the web server you will also need to add the IUSR user to have permissions on that directory

[harsh00008]

hey buddy I'm using Easy php..and testing the project on localhost

 

I checked this line on the php.ini file

 

;session.save_path = /tmp

 

and i checked the tmp folder...

 

and the session files are present there 

[.josh]

so...does that folder have appropriate permissions?

 

just for shits and grins, try this:

 

<?php
session_start();
echo session_id();
?>

 

does something echo?

yeah it echoes a hash like some md5 encryption

Well i think if some session files are present there then i guess it must be having proper permissions

 

but even if so...how do i change the permission on'em?..like for the web hosting i CHMOD them via ftp manager..

 

I'm really confused y this thing isn't working

 

 

 

[ShaunO]

Add

 

echo session_id();

 

Just below session_start(); on each of those test pages

 

Then go to each one and check if they stay the same

[PFMaBiSmAd]

Get php to help by turning on full php error reporting. Add the following two lines immediately after the first opening <?php tag on both pages -

 

ini_set ("display_errors", "1");
error_reporting(E_ALL);

Yeah they do echo the same session id

i got these three error lines on page1.php

Much better, as I first thought you need to change the directory it saves session files to

Instead of /tmp try C:/php/sessions

u mean i change this line ;session.save_path = /tmp

 

to

 

;session.save_path = C:/php/session

 

???

 

but i don't have a folder existing as c:\php

 

I have easyphp installed for the localhost and the path of php is

 

C:\Program Files\EasyPHP1-8\php

Can I just recommend that you get WAMP Server. I used EasyPHP for a while but found WAMP Server far better.
