help withsyntax for if else statement

[John T]

Hi, I am creating a genealogy website using The Next Generation Software. Access to the site will  require the users to log in, they will also be assigned a tree. It will have two family history trees. At the moment it is on a local wamp server.

My question is: I have two custompages, page1.php and page2.php.

I only want users assigned to tree1 to be able to see page1.php and users assigned to tree2 only to be able to see page2.php.

I think I need an if else statement on each of the two pages or, they could be directed there from a welcome.php page. but as I have no knowledge of php I am clueless as to how or what to put in the if else statement and where it should go.

I have googled php syntax and seen lots of code but they all seem to use “echo” but I do not need print anything just, go to  certain pages.

I have seen the following in various pages of code used in the program if it helps-

include($cms['tngpath'] ."checklogin.php");

$assignedtree = $_SESSION['assignedtree'];

$currentuser = $_SESSION['currentuser'];

Any help would be appreciated many thanks for reading this.

Regards,

John.

Do you mean something like:

 

$assignedtree = $_SESSION['assignedtree'];
$currentuser = $_SESSION['currentuser'];

if($assignedtree == 'tree1')
{
   echo $currentuser  . ' is looking at tree 1';
}
elseif($assignedtree == 'tree2')
{
   echo $currentuser  . ' is looking at tree 2';
}
else
{
   echo $currentuser . ' did not match either tree';
}

 

Replacing the tree1 and tree2 with whatever you're storing in the session.

Hi Veteah thanks for the reply.

 

I think you are on the way to fixing this. The only thing is I do not need the echo part.

Insted I would like the specific page to open, either page1.php or page2.php

 

It is so frustrating not knowing php.

[Veteah]

In that case, all you have to do is add

 

include('file_path');

 

 

... where the echo is.

Veteah, I am not used to getting replies this quick from a forum, thanks so much.http://www.phpfreaks.com/forums/Smileys/nrg_alpha/happy-01.gif

I will give this a try and let you know.

Might be tomorrow as I am just off out.

Regards,

Hi Veteah,

I tried the echo statement first to see the result and it was as expected, showed who was logged in and their tree.

Then I tried the include statement and got parse errors.

The below is the start of my page up to your code. It shows different things I have tried and the parse errors.

Thanks,

John

 

<?php

 

include( "../begin.php"); 

if( !$cms['support'] )

$cms['tngpath'] = "../";

include($cms['tngpath'] ."genlib.php");

include($cms['tngpath'] ."getlang.php");

include($cms['tngpath'] ."$mylanguage/text.php");

include ($cms['tngpath'] ."checklogin.php");

include($cms['tngpath'] . "log.php" );

tng_db_connect($database_host,$database_name,$database_username,$database_password) or exit;

$logstring = "<a href=\"extrapgs/welcome.php\"welcome</a>";

writelog($logstring);

preparebookmark($logstring);

}

elseif($assignedtree == 'tree_2')

{

  echo $currentuser  . ' is looking at tree 2';      // echo is showing who is signed in and which tree is being looked at.

}

else

{

  echo $currentuser . ' did not match either tree';  // This also works

}

/*In that case, all you have to do is add

 

include('file_path');

Hi Veteah and thanks for pointing me in the right direction

All is now sorted with this, the echo statement only needed a page link.

For those interested in the result the code is below.

 

$assignedtree = $_SESSION['assignedtree'];

$currentuser = $_SESSION['currentuser'];

<?php    if ($assignedtree == 'tree1') {

echo '<a href=\'page1.php\'>Page Title</a>';

}

elseif ($assignedtree == 'tree_2')

{

echo '<a href=\'page2.php\'>another page title</a>';

}

else

{

    echo 'You don\'t have a user account Please register';

 

}

?>
