How to make the navigation block appear only for authenticated users?

By xand on 2 Nov 2004 at 08:05 UTC

Apparently, this used to be possible with:

global $user;

if ($user->uid) {
if ($menu = menu_tree()) {
return $menu;
}
}

but not any more.

Also, if you don't know that, could you tell me in which .module the navigation block is defined?

Try this

droopy commented 2 November 2004 at 09:18

global $user;

if ($user->uid) {
 if ($menu = theme_menu_tree()) {
   $menu = "<div class=\"menu\">". $menu . "</div>";
   return $menu;
 }
}

Hmm. That works partially.

xand commented 2 November 2004 at 11:42

Hmm. That works partially.

When authenticated, it works as usual.

when un-authenticated, the navigation block _title_ still appears, even though there is no content in the block.

xand commented 2 November 2004 at 15:34

Strange. I'm using a derivation of "pushbutton", but I can't see how the theme would affect it. In fact, I suspect your code should probably be sufficient, because my addition should be implied.

I think that it doesn't really matter, the differences is really quite tiny.

Interesting site.

I was browsing it a little, and http://www.opensourcetheology.net/node/228 generates a Fatal Error.

Also, I wonder if you would want a contributions such as:

Thanks for spotting the fatal error. Why don't you contact me via OST and I'll respond on the other issue privately.

how to use php

jbc commented 2 November 2004 at 12:31

I want to do something similar. Can you explain how you actually use the php text in the blue box? Do I just cut and past the whole lot into the path box of the blocks admin page?

When I've attempted something similar in the past, it LOOKs as though only the bottom line has pasted...

(I'd also be interested to know how you "quote" php entry like that...)

thanks

You create a new block under

xand commented 2 November 2004 at 15:25

You create a new block under administer/block with my code block above as text.

To quote highlighted php, simply paste the php into your reply.

Block title

eloieli commented 8 December 2004 at 08:45

My only problem with this nifty piece of code is that it no longer puts the persons username at the top of the Navigation menu.

Anyone know how to add this?

codefilter.module

Steven commented 2 November 2004 at 16:33

The module which handles the php coloring is codefilter, and can be found in the download section. It transforms any text between <?php and ?> tags into:

this;

Thanks

block title = user_id ?

stelman commented 4 November 2004 at 09:21

One of the default features I like is the title of the block changing from "Navigation" to user_id after login. I looked through the code a little, but didn't find where this is done. Any idea how to add that to this block code?

You need to write a module

chx commented 15 November 2004 at 10:49

You need to write your own module, which implements at least hook_block() . Let test.module be something like this


function test_block($op = 'list', $delta = 0) {
  global $user;

  if ($op == 'list') {
     $blocks[0]['info'] = t('Test');
     return $blocks;
  }
  else {
    $block = array();

    switch ($delta) {
      case 0:
        if (!$user->uid) return;
        if ($menu = theme('menu_tree')) {
           $block['subject'] = $user->name;
           $block['content'] = '<div class="menu">'. $menu .'</div>';
        }
        return $block;
     }
  }
}

this works great...

korayal commented 8 February 2005 at 19:36

can we apply this code to the other menus we created from the "administer>menus"?

i mean;

global $user;
if ($user->uid) {
if ($menu = theme_menu_tree()) {
   $menu = "<div class=\"menu\">". $menu . "</div>";
   return $menu;
}
}
else {return;}

I guess in there we have to change the "theme_menu_tree()" but where do we find the code that we will change them with?

theme_menu_tree($pid)

keve commented 22 August 2005 at 13:57

theme_menu_tree($pid) function list the menu items with the parent menu item ($pid).

You can look up the parent menu id at /admin/menu
(when you click "edit", the $pid appears at the end of the url e.g: admin/menu/item/edit/42)
For example I have "Main Menu" defined with menu id #42.
So that i use the function theme_menu_tree(42) to list all the menu items under "main menu"

Display menu block by role

seannyob commented 12 October 2005 at 18:08

groovy, good code, i modified it this way:

If you create a menu in administer > menus, and create a role 'foo' and only want your block to display to users in role 'foo', you can do this by creating a php block, finding the menu id (hover over the "edit" option, and get the trialing number) and using the following code where:

foo = your role
XX = your menu id number

<?php
global $user;
if (in_array('foo',$user->roles)) {
if ($menu = theme_menu_tree('XX')) {
$menu = "<div class=\"menu\">". $menu . "</div>";
}
}
return $menu;
?>

Block to disappear for authorised users

jbc commented 3 November 2004 at 19:51

Could this php be changed quite simply to reflect the opposite requirement? I.e. say I have a "start here" block which I want unauthorised user to see. But once a user is authorised I want that block to disappear?

Well, i'd imagine that the ea

xand commented 4 November 2004 at 11:15

Well, i'd imagine that the easiest way to do that would be to create another user login block, because that block automatically dissappears once logged in?

---
www.symplification.com

how would that be done?

jbc commented 4 November 2004 at 13:03

I don't understand how that would be done. Presumably the login block disappears because it's coded to within drupal somewhere. Just creating another block and calling it login isn't going to help, plus there's no option for replacing the old one. Am I missing something?

Say I did create another block using the php you've set out, can I still place html into it? for example to provide a select navigation list for the authorised user? Or would that have to be done in php?

This seems to do the trick

droopy commented 4 November 2004 at 13:34

This seems to work. You would need to use php to insert html.

global $user;

if (!$user->uid) {
  $output = "This box <b>disappears</b> once a user is logged in.";
	return $output;
	}

parse error

jbc commented 6 November 2004 at 13:15

Thanks, I'll look forward to getting this working: at my first attempt I'm getting the following error:

(I've had to insert "lesser-than angled bracket" in text, because otherwise the remainder of my post diappears. (how do I avoid that?)

Any other possiblilities?

Try replacing $output with $content?

I know it works with Drupal 4.5...

oh yes. Simply replac

xand commented 4 November 2004 at 14:20

oh yes.

global $user;
if ($user->uid) { 
   $content = 'Hello World!'; 
   return $content;
}

Simply replacing "Hello World!" with whatever you please. It does not even have to be on one line, so you can simply paste whatever html code you had in mind.

(oops. I had this reply open for a long time :p)

You can use any variable name... the ! before $user determines whether you want the block to appear when there is a user, or when there isn't.

How to show block for only one book

_Martijn_ commented 4 November 2004 at 11:33

I'am trying to show the book navigation block for only one book. In total there are 4 books. I can't get it done with the path expressions. I also tried to alter the php code but this ended up with a completely disabled block.
If anyone can give me a pointer I would be grateful.

Martijn

A possible method would be:

xand commented 4 November 2004 at 14:28

A possible method would be:

1. Enable path.module
2. edit *each* book page of that particular book to a certain path. e.g. about/1, about/2 etc.
3. set the path in the blocks module to that certain path. e.g. < ^ about >

This will mean that the book navigation module will only appear for that particular book.

patch to 4.6 block.module for this, real solution coming in 4.7

dww

commented 13 February 2006 at 14:15

i wrote a patch to the 4.6 version of block.module that allows site admins to just select via checkboxes what roles should be able to view any given block. see http://drupal.org/node/49154 for details. also, this functionality will be added to 4.7 sometime soon (see http://drupal.org/node/18018 for info on that discussion).

i edited the user.module...

nvl.sateesh commented 7 May 2007 at 04:33

hi..

in order to display the Navigation Menu only for authenticated users, I edited the user.module like this:
1. Went to hook_block of the module.
2. it has 4 blocks: case 0, case 1, case 2 and case 3
3. in case 1, to the whole code i put the if clause as if($user->uid)

probably this is somewhere near the 583rd line of the module...

like this:

    case 1:
global $user;
if($user->uid){
if ($menu = theme('menu_tree')) {
           $block['subject'] = $user->uid ? check_plain($user->name) : t('Hi Guest');
           $block['content'] = $menu;
        }
}
        return $block;

it works well. i am not sure if editing the module has any issues. if there are any, plz correct me... i am newbie...

So here is how it works (im using 6.8 version):
