includes within includes

hateraid

sup guys,
im totally new to php and i need some help.

i need help with includes, setting different variables to change certain includes on a page. basically making layers of includes.

basically on the index page i have a table with a menu and code for the include (lets call it layer 1). the menu links are home and roster.
now within the roster page i have a similar situation. within it is a table with a menu and that include code, but with a different variable(layer 2). the links in the roster page are active roster and alumni roster.

when i click the links in the roster page, it goes to the home page(as if i clicked a link on the index page).
how can i make it so that the links in the roster page change the content in it only?

heres the code for the index page

<table width="500" cellpadding=1 border=1 cellspacing=1>
           <tr><td>

  --menu links are here--
<a href="?z=home">Home</a>
<a href="?z=roster">Roster</a>

       </td></tr>

       <!-- content -->
       <tr><td>
       <?php
       $id = $HTTP_GET_VARS["z"];
       $ext = "php";
       if ( !$id || $id == "" )
       {  include "home.php";}
       else if ( file_exists( "$id.$ext" ) )
       {    include "$id.$ext";}
       else
       { echo "<center><h2>404 Error: File not found.</h2></center>"; }
       ?>

      </td></tr>
       </table>
</td></tr></table>

now heres the code for the roster page

<center><b><font size=5>Roster</font><b><br>
<table width="500" cellpadding="10" border="0" cellspacing="0">
                <tr>
                    <td align=center>
                    <div><a href="?x=activeroster">Active roster</a>&nbsp;&nbsp;|&nbsp;&nbsp;
            <a href="?x=alumniroster">Alumni roster</a>
                    </div>
                    </td>
                </tr>

            <tr><td> 
       <?php
       $id = $HTTP_GET_VARS["x"];
       $ext = "php";
       if ( !$id || $id == "" )
       {  include "default.php";}
       else if ( file_exists( "$id.$ext" ) )
       {    include "$id.$ext";}
       else
       { echo "<center><h2>404 Error: File not found.</h2></center>"; }
       ?>

            </td></tr>
        </table>

heres the link to the exact page to view what im talking about.

Why two seperate scripts? The URI's you are giving for the anchors all indicate that the browser should look at the index page ... so why not just integrate the code?

Or else if you truly want a seperate roster page (and that's perfectly legitimate), then code the anchor tags to point to roster.php?x=activeroster and so on ... or am I missing something? 😕

im using two scripts because the roster page is the only one with several layers of content
that and im trying to avoid using frames, learning php too of course 🙂

i tried changing the anchor tags to roster.php?x=activeroster and so on, but they change the whole page entirely to it

i changed the active roster link to show what i mean.

it works when there's just one script for includes, but not when theres one within another.

any idea how to get around this?
i mean theoretically, if you set a script to function with a certain variable, say variable A, it shouldnt be affected if you have another script that functions with variable B

thanks for helping man, much appreciated

$id . $ext

now if
$ext = "php"

would give
$id . $ext is equal to "pagenamephp"

the point in bewtween id . ext
does mean only + (plus, add these 2 strings variables together)
it is not a character "." ---- point (punctuation)

so make
$ext = ".php";

and you will see it work alright

i tried changing

$ext = "php";

to
$ext = ".php";

and it doesnt work. it now gives the 404 error that i coded if the targeted php file doesnt exist.

the extention is fine,

$ext = "php"; does give name.php not namephp

anyone have any other ideas?

On your roster.php, you want to check the value of "X". So, the links will all be like this:

<a href="?z=roster&x=(whatever)">Whatever</a>.

This way the main part of the page interprets "z", and your roster.php interprets "x".

hateraid

thanks a lot man,

i had no idea about the & within the anchor tags to interpret several variables

thanks again!

yes, I missed a little detail

you have quotes around!

if we set $ext = "php"

include ( $id.$ext ); // will give 'pagenamephp' and file cant be found

but you happen to use
include ( "$id.$ext" ); // will make 'pagename.php' , as you want, because of the quotation marks

Glad you're understanding this and getting it to work!
