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

Posted by xand on November 2, 2004 at 8:05am

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

Posted by droopy on November 2, 2004 at 9:18am

<?php
global $user;

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

Hmm. That works partially.

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.

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.

how to use php

Posted by jbc on November 2, 2004 at 12:31pm

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

Shalom!

Block title

Posted by eloieli on December 8, 2004 at 8:45am

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

Posted by Steven on November 2, 2004 at 4:33pm

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:

<?php
 this; 
?>

block title = user_id ?

Posted by stelman on November 4, 2004 at 9:21am

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

Posted by chx on November 15, 2004 at 10:49am

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

<?php
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...

Posted by korayal on February 8, 2005 at 7:36pm

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

i mean;

<?php
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)

Posted by keve on August 22, 2005 at 1:57pm

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

Posted by seannyob on October 12, 2005 at 6:08pm

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

Posted by jbc on November 3, 2004 at 7:51pm

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?

Posted by xand on November 4, 2004 at 11:15am

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?

Posted by jbc on November 4, 2004 at 1:03pm

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?

Shalom!

Thank you for your attention,
john

This seems to do the trick

Posted by droopy on November 4, 2004 at 1:34pm

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

<?php
global $user;

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

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

Posted by _Martijn_ on November 4, 2004 at 11:33am

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:

Posted by xand on November 4, 2004 at 2:28pm

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

Posted by dww on February 13, 2006 at 2:15pm

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...

Posted by nvl.sateesh on May 7, 2007 at 4:33am

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:

<?php
    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...
