How do I make something like this

yoursite.com/?id=1&act=act

I am basically asking how does the "&" part of it work?

It's a series of parameters you are passing. The & or & seperates the parameters apart from each other.

Any way you can explain just a little I am new to PHP. Don't give me the answer just point me in the right direction, Thanks

index.php?id=1&act=act&this=that

The parameters are first taken from the URL string by PHP, and it is set off by the "?"

So the above example would be digested by PHP as: id=1&act=act&this=that

Then it is split into key=value pairs by the "&"

This would become:
id=1
act=act
this=that

Then each pair is split into key => value array into the $_GET array by the "="

This would result in the following array using print_r($_GET):
Array {
[id] => 1,
[act] => act,
[this] => that
}

ah so I would just set a if statement that executes code if the $_GET variables correspond? like if id=1 and act=act

Yes, but it would be used like this:

if ($_GET['id'] == 1 AND $_GET['act'] == 'act')
{
...
}

lol Yeah that's what I meant I am just lazy

Another question I have is how to do this with forms. Like the first part of the form is the user selects a type then they select the second type

I need to keep it on one page like instead of going from

index.php?id=1

to

index.php?act=type2

I need

index.php?id=1&act=type2

I was thinking something with sessions but I am not sure

You could create a new merged array and then build the param string from that:

$params = array('act' => 'type2');

$params = array_merge($_GET, $params);

echo 'index.php?' . http_build_query($params, '', '&');

Yeah but my problem is I need to keep the selection from the first page Like if they choose

type1 that might have different choices on the next form than say type2

Here is a rough draft of my index page

PHP Code:

$link = $_SERVER['PHP_SELF'] ;
      
      $training_link = $link ."?id=2" ;
      $profile_link = $link ."?id=1" ;
      $occ_train_link = $link ."?id=3" ;
      
      
      echo"<a href='$profile_link'>profile</a> <br/>";
      echo"<a href='$training_link'>Training</a> <br/>";
      echo"<a href='$occ_train_link'>occ train</a> <br/>";
       
      if ($_GET['id'] == "1"){
           $user = profile($user);
          }
      elseif ($_GET['id'] == "2"){
           require("training.php") ;
       $user = training($user) ;
          }
      elseif ($_GET['id'] == "3"){
           require("occtrain.php") ;
        $user = occ_train($user) ;
           } 


Now here is the page where I am sending the data for the "training"

PHP Code:

<?php
function training($user){
//check for Input
if(isset($_GET['train']) ){

if($_GET['train']=="weap"){
     if($_POST){
         if($_POST['type'] == "offense"){
             $gain = $user['stamina'] * 0.2;
             $user['weapoff'] += $gain ;     
             $expgain = $gain * 5 ;
         $user['exp'] += $expgain ;
             $user['expneed'] -= $expgain ; 
             $user['stamina'] -= $gain * 5;
             $user['maxsta'] += $gain * 4;
             
             echo "You have gained " . $gain . " Weapon Offense! <br/>" ;
             echo "Doing this you have used " . $gain * 5 . " stamina! <br/>" ;
             echo "Your maximum stamina has increased by " . $gain * 4 . "!" ; 
             
            }
         if($_POST['type'] == "defense"){
             $gain = $user['stamina'] * 0.2;
             $user['weapdef'] += $gain ;     
             $expgain = $gain * 5 ;
         $user['exp'] += $expgain ;
             $user['expneed'] -= $expgain ; 
             $user['stamina'] -= $gain * 5;     
             $user['maxsta'] += $gain * 4;
             
             echo "You have gained " . $gain . " Weapon Defense! <br/>" ;
             echo "You have used " . $gain * 5 . " stamina! <br/>" ;

I need the user to choose a type of training then choose which type of the training to do

I guess I don't understand what you mean then. The example I gave would merge the original GET parameters with the new ones. The example also works with the GET parameters, and not the POST parameters.

Hmm, sorry about this I tend to complicate things for myself so much and it makes it hard on the people who are trying to explain stuff to me let me see if I can make some type of algorithm for what I want

1. User selects which page of my site to go to

2. User selects training

3. for example user selects weapon training

4. the user then selects either offense or defense training

5. Based on selection execute code and update user stats based on selection.

If you want to keep the get params from the previous request and modifiy/add to them, then you can use the previous example or create a copy of the $_GET array and change the values of that to create a new parameter string.

The problem I am having is the way you said doesn't effect the url at all. Which is my problem I need it to go from

?id=2
to
?id=2&train=weap

but instead it replaces the ?id=1 in the url with train=weap which messes up my script since I need to keep $_GET['id'] to be same as 2 to require the training page if you look above at my index page

-cough- I added and || to my index page and it works now. I know its not the same as what i am used to seeing but it works. that's all I can ask for with my skill level

You could store the values as $_SESSION variable and build up a series of values that can be checked each time the person goes to a new screen

If (isset($_GET['id'])) $_SESSION['id']=$_GET['id'];

Then on the next screen you can check to see what the value of the $_SESSION value it and go from there.

The values are strored until you erase the value.

Yeah I was gonna do that, but the way I have it set up now is if $_GET['id'] or $_GET['train'] isset then require my training script
