How to change the theme for a particular admin page in drupal?

Question

I have a page with url ?q=admin/settings/history . Is there any way by which I can change the template for this page alone. I tried using hook_preprocess_page but I was unable to change the layout of page. Could someone please lead me in the right direction?

Answer 1

Yet another solution, in a couple of lines of code, is:

hook_custom_theme

Return the machine-readable name of the theme to use for the current page. This hook can be used to dynamically set the theme for the current page request. It should be used by modules which need to override the theme based on dynamic conditions

e.g

/**
 * Implements hook_custom_theme
 */
function MYMODULE_custom_theme() {
  // Set path specific theme.
  if (current_path() == 'admin/settings/history') {
    return variable_get('custom_theme', 'theme_name');
  }
}

Core example: system_custom_theme

Update: To use a specific template you can override page.tpl.php

• copy page.tpl.php to page--admin--settings--history.tpl.php, clear caches (theme registry) and use that.

Answer 2

It looks like you might be looking for a ThemeKey module:

ThemeKey allows you to define simple or sophisticated theme-switching rules which allow automatic selection of a theme depending on current path, taxonomy terms, language, node-type, and many, many other properties. It can also be easily extended to support additional properties exposed by other modules

Emphasis mine.

You can either use it directly, or use it's source code as an example - it's GPL, so you have the right to do it.

Answer 3

In a simple way you can change the theme key by checking the condition,

/**
 * Implements hook_init().
 */
function <module_name>_theme_init() {
    global $theme_key;

    if ($_GET['q'] == "admin/settings/history") {
        $theme_key = '<Your new Theme key>';        
    }
}

Answer 4

You can use Page Theme module

The Page Theme module is a simple and easy module to use which allows to use different themes than the site default on specific pages.

Answer 5

I would suggest to implement a custom module that changes the theme being used for specific pages. It is enough to implement hook_custom_theme() as follows:

function mymodule_custom_theme() {
  if (arg(0) == '' && is_numeric(arg()) && arg(3)== history
) {
    return 'go theme page what you want yo use';
  }
}
