Where in the theme are the tabs printed / giving tabs to admins only Where in the theme are the tabs printed / giving tabs to admins only

On giving View, Edit, Revision, etc. tabs to administrators only.
In Drupal, tabs are not printed by the node, but by the page. On the one hand, since views and administrative pages and anything else you can think of can have tabs, this makes sense. But on the other hand every node can have
But in any case, if you're looking to change the presentation of tabs somehow (or as in our case, restore them to a theme design from which they had been removed), you will find the place to look is not node.tpl.php but page.tpl.php.
For instance, line 42 from bluemarine's page.tpl.php:
<div class="tabs"><?php print $tabs ?></div>
(Special _phptemplate_variables pseudo hook function can add to and modify variables headed to a template. The one below styles itself after Garland's.)
<?php
/**
* Modeled on Garland's implementation of _phptemplate_variables.
* Personally I think I like using the switch statement.
*/
function _phptemplate_variables($hook, $vars = array()) {
if ($hook == 'page') {
// if the user does not have basic administration permissions,
// do not show any tabs (backwards compatibility with theme)
if (!user_access('access administration pages')) {
$vars['tabs'] = '';
}
return $vars;
}
return array();
}
?>

Made display of the div conditional
For this unusual use where tabs are eliminated for non-administrator users, we make display of the tabs div itself conditional on there being tabs to display:
<?= $above_content; ?><?php if ($tabs) { ?>
<div class="tabs"><?php print $tabs; ?></div>
<?php } ?>
<?=$content?>
Removing tabs for non-admins
Hey Ben,
Thanks for this tutorial, its really cool. But me not being a php expert, I'm having trouble integrating this snippet into my theme. This is because my template.php file already has function _phptemplate_variables declared using a switch statement that allows certian pages to have different background colors. I cant re-declare the variables, so I'm looking to see how I can integrate this statement into the statement declaring the _phptemplate_variables. I've provided an example of how the code is written into my template file.
function _phptemplate_variables($hook, $vars = array())
{
switch($hook)
{
case 'page':
if (module_exists('path')){
$alias = drupal_get_path_alias($_GET['q']);
$suggestions = array();
$template_filename = 'page';
foreach (explode('/', $alias) as $path_part)
{
$template_filename = $template_filename . '-' . $path_part;
$suggestions[] = $template_filename;
}
$vars['template_files'] = $suggestions;
}
break;
}
return $vars;
}
I tried adding just the if statement benearth the $vars['template_files']=$suggestions; statement, and returning the array at the bottom beneath return $vars; , but that didn't work.
Would you have any thoughts on how to remove tabs for non-admins on pages that already have that function and variables declared for other purposes?
Many thanks!

Shouldn't have to do anything for non-admins
Tabs should not print at all for non-admins, people don't see tabs they don't have access to, so simply turning off permissions for viewing revisions, say, may take care of it.
For the general issue of adding to the _phptemplates_variables, yes, just add
case:clauses orswitchstatements to the function.Post new comment
