Put URL into the Array...

[jjdave]

Hi All,
I am trying to create Navigation Trail, so as Clicks are made from One (Php Page) to Another, the URL needs to be Copy and stored into the array.

Any headstart will be great.
Thanks.

You need a method to identify the user from page to page (sessions or IP) and a method of storage (either the file sytem or a datebase). Once you have established that the code is very simple.

Actually Page retrives data from the Database, Example Cars:

Such as Cars -> GM -> Oldsmobiles -> Cutless -> 1999
or Cars -> Honda -> Pilot -> Yr 2000
or Cars -> Toyota -> Camry -> yr 2000
etc. etc. etc.

I just want to know how to copy URL & put into the Array which will be created on the fly an not stored into the database.

Thanks.

<?php
session_start();
$_SESSION['history'][] = $_SERVER['PHP_SELF'];
// or maybe this if you need the query string
$_SESSION['history'][] = $_SERVER['REQUEST_URI'];
?>

Thanks a lot.

I need to try this out.

So I started new session and I presume it stores URL in the Session ($_SESSION['history'][]) variable, how can I print this variable???

I did try following:

    session_start(); 
    $_SESSION['history'][] = $_SERVER['PHP_SELF']; 
    $test = array($_SESSION['history']);
             echo $test; 

But it does not print the array. I need to print the URL as many time as php page is submitted to itself.
Thanks.

foreach($_SESSION['history'] as $output) {
echo $output;
} 

Just as a basic output. You an then refine it to add your >> bits

You must use something like for...each cycle to print all the adresses

[jjdave]

Thank You.

For...Each cycle works well.

There is one BUT. When I Refresh (the page) or use Brower Buttons (Back or Forward) it also appends those URLs as well. Is there a any way to trap that error?

Thanks a lot. I did achieve my objective with For...Each.

it depends how you want to eliminate the duplicate entrys.

by default, the array entries will be sorted in the order they were added to the array.

some ways to do it:

use array_unique()
this may affect the sort order in a way that may be desireable, or not desireable to you.

another way could be only add an entry to the history if it does not already exist

if (!in_array($_SERVER['PHP_SELF'], $_SESSION['history'])) {
    $_SESSION['history'][] = $_SERVER['PHP_SELF'];
} 

but doing these things are now making this into a list of visited pages, not a history of their click path. im not sure if thats what you want.

You are correct, I do not want List but I do want Click Path.

You all have given me main Points or Proper Sentex. Now I need to plug in the info properly.

Thank You.
