Show block to certain users or roles only- Drupal 4.6
Note: Some of the examples from this section may not work with versions of Drupal older than 4.5.
Example: you want to show a block only to logged-in users. Site administrators often wish to restrict anonymous users from seeing certain (custom) blocks. Placing the following code in a PHP block will achieve this.
<?php
global $user;
if ($user->uid) {
return "This block is only visible for logged-in users.";
} else {
return;
}
?>Replace the string "This block is only visible for logged-in users." with anything you want to display only to logged-in users.
You could also put the contents in an IF / ENDIF statement:
<?php
global $user;
if ($user->uid): ?>
<ol>
<li><a href="/linky">lorem ipsum</a></li>
<li><a href="/linky_too">lorum ipsum</a></li>
</ol>
<?php else:
return;
endif;
?>If you want a more html friendly way to display the information contained.
The block will not be shown at all for users who are not logged-in. You can replace the single return in the else-block with, e.g.,
<?php
return "This block is only visible for logged-in users.";
?>to show some text instead of not displaying the block at all.
Example: Wrapping HTML content so it is visible only to anonymous users. This example uses an if/endif construction to wrap some HTML in a few lines of PHP which will show the content only to anonymous users.
<?php
global $user;
if (!$user->uid) : ?>
<p>This content will be visible only to anonymous users.</p>
<?php else {
return;
}
endif;
?> 4.6 Example: Showing a block only to certain users. If you want to show a certain custom block only to a certain user, you can use the following code in a PHP block:
<?php
global $user;
if ($user->uid == 19) {
return "This block is only visible for the user with the user-ID 19.";
} else {
return;
}
?>4.6 Example:To show to specific roles only in Drupal 4.6. In this example the role is "admin user".
<?php
global $user;
$output = '';
if (in_array('admin user',$user->roles)) {
$output .= '<i>A block for admin users</i>';
$output .= '<ul>';
$output .= '<li><a href=/"?q=Admin/">Administration interface</a></li>';
$output .= '</ul>';
}
return $output;
?>
