Re: [PHP] Passing var from one page to itself
Hi there,
Thanks so much everyone I really appreciate the help! I have it working
now using hidden tags from each page to the next.

Hi Aslan:
Keeping it all on one page (one script) is fine -- no problems with that.
Here's the technique I use.
$step = isset($__POST ['step']) ? $__POST ['step'] :1;
if($step == 1)
{
// do the first page stuff (Symptoms)
// with a POST form that has an input type=hidden name=step
value=1
}
if($step == 2)
{
// do the second page stuff ( Troubleshooting questions)
// with a POST form that has an input type=hidden name=step
value=2
}
if($step == 3)
{
// do the third page stuff (Answer to problem)
// with a POST form that has an input type=hidden name=step
value=3
}
If you want to pass variables between pages (trips from client to the
server nad back again), you have four options, namely: 1)
writing/reading a file; 2) writing/reading a database entry; 3)
passing via a POST/GET; 4) or using SESSIONS.
For most things, I prefer using POST/GET and/or SESSIONS. Try this format:
$var1 = isset($_POST['var1']) ? $_POST['var1'] : null;
$var2 = isset($_SESSION['var2']) ? $_SESSION['var2'] : null;
That's the way I pass data between client and server.
However, what you are describing sounds a bit like this:

With this example, I'm not passing anything to the server --
everything is kept client-side and is quick.
If interested, all the code is there.
Cheers,
tedd

[PHP] Passing var from one page to itself
Hey there,
I have a problem where I have a simple -script that I am wanting to
pass back to itself three times
1) Symptoms - 2) Troubleshooting questions 3) Answer to problem
The page is passing the vars from the first page to the second, but the
first pages vars are not passed to the third (but the second page is)
I am using includes for each sectional page and passing it back to itself
if($submitted == )
{
include 'inc/tshoot2-input.php';
}
if($submitted == symptoms)
{
include 'inc/tshoot2-symptoms.php';
}
if($submitted == submitted)
{
include 'inc/answers.php';
}
The tool will ultimately be on www.adslgeek.com/troubleshooter/
I have it currently all on one page, but it isn't quite what I was after
..
Any help would be appreciated!

Re: [PHP] Questions about finding ranges
You guys are just awesome! Thanks already for the help I really appreciate it! My site is up on adslgeek.com/troubleshooter but I have a DNS problem that I have to fix over the weekend. :-( The scenario is an input dashboard, with various settings that measure the quality of an ADSL line. I have then mapped out all of the possible faults that I could think of that might fit those settings(did up a flowchart of questions that is huge). So for simplicity say the inputs are: - X Noise on line - X Distance from exchange - X Disconnections per day - Slow speed of x Then I have a list of all the possible scenarios eg 1) Disconnections caused by noisy line 2) Disconnections caused by distance 3) Slow due to noisey line 4) Slow due to distance So how I have currently done this is heaps of nested if statements, but that is going to get so unmanageable, and the speed is going to become a factor. What I had envisioned was input all the possible vars, and then SQL just finds the closest variable. It is kind of similar in logic to a search engine type script - if I had the strings disconnections and noisey of 52 then it just finds the closest record. Does that make sense? Thanks heaps you guys have been so helpful.

Make sure in your data that you have no overlap. Row 1 =0 - 499 Row 2 = 500 - 999 Row 3 = 1000 - 1499 But that wouldn't work quite right I don't think. But where it can get a bit more hairy is that I want to have a whole range of variables that are input from an entry table, and then it just finds the the vars that are the closest to what is searching for all the vars. The closest code I have seen doing something similar is where there it is finding if an IP is in a certain range. Does that make sense? feel free to email me if you need more explanation. It is kind of like a multi variable search engine, that is finding the root cause of the symptoms that are the very best fit given the multi-variables...
