How to add a custom page.tpl based on content types.

Have you tried with page--(content type name).tpl.php?
Also check this:
http://drupal.org/theme-guide/6-7
http://drupal.org/node/1089656

The only thing "page" knows about are the path arguments. Nothing is in there to pick-up on node types. You need to help it out.

Here's some code which should go into your template.php file and THEME_NAME must be replaced with the machine readable name of your theme.

/**
 * Variables preprocess function for the "page" theming hook.
 */
function THEME_NAME_preprocess_page(&$vars) {

  // Do we have a node?
  if (isset($vars['node'])) {

    // Ref suggestions cuz it's stupid long.
    $suggests = &$vars['theme_hook_suggestions'];

    // Get path arguments.
    $args = arg();
    // Remove first argument of "node".
    unset($args[0]);

    // Set type.
    $type = "page__type_{$vars['node']->type}";

    // Bring it all together.
    $suggests = array_merge(
      $suggests,
      array($type),
      theme_get_suggestions($args, $type)
    );

    // if the url is: 'http://domain.com/node/123/edit'
    // and node type is 'blog'..
    // 
    // This will be the suggestions:
    //
    // - page__node
    // - page__node__%
    // - page__node__123
    // - page__node__edit
    // - page__type_blog
    // - page__type_blog__%
    // - page__type_blog__123
    // - page__type_blog__edit
    // 
    // Which connects to these templates:
    //
    // - page--node.tpl.php
    // - page--node--%.tpl.php
    // - page--node--123.tpl.php
    // - page--node--edit.tpl.php
    // - page--type-blog.tpl.php          << this is what you want.
    // - page--type-blog--%.tpl.php
    // - page--type-blog--123.tpl.php
    // - page--type-blog--edit.tpl.php
    // 
    // Latter items take precedence.
  }
}

And this will work for all node types and look! You can even have a custom template for editing your blog. It's easy to get carried away with this stuff though so be careful. If you have tons of templates, you're doing something wrong.

I looked for this for a few days when I first started looking at drupal and still cant believe that it is so hard to have a different template based on page type, I am building a base site for 8 other websites in the accommodation industry so it needs to be flexible with page layout with different accommodation types.

What I have found is that all the help and instructions are for drupal 6 , it is quite hard to find the different settings etc for Drupal 7.

I thought I would post this as a help to any one trying to have a different .tpl page for page type.

Anyhow what I have done for this problem.

For Drupal 7

Go to http://www.yoursite.com/user and log in.

Then go to Structure > Content types + Add Content Type
Add Name we will use the name example so type in example (Take note of the machine name which in this case will be example)

Enter a description of the new page so people know what they are adding to the site.
As we are just adding a basic one now so please now go to the bottom and click save content type.

Ok now we have the content type example in the list. When you go to Content > + Add content there is a content type “example” there.

Now we need to go to our theme and add the code below in your template.php file. Take note of two things

1. Search the template.php file first to see if there is already and instance of _preprocess_page . If you have used a template to start from then this may already be in the template.php if it is then please add the code indide the function to the existing function.

2. Secondly change the YOURTHEMENAME to your theme name and leave the _preprocess_page there. (I know this sounds like everyone should know this and I did but my Junior programmer struggled with this part).

// Copy from here Template for Content type

function YOURTHEMENAME_preprocess_page(&$vars) {
    // - page--example.tpl.php  

 if (isset($vars['node'])) {
$vars['theme_hook_suggestion'] = 'page__'.$vars['node']->type; //
}
}
// Finish copy Template for Content type

Now in the same folder that you have your page.tpl.php file create another template file (remember we are using example)

The file name would be page--example.tpl.php

IMPORTANT!
Now upload the files and then CLEAR THE CACHE Go to configuration > Performance and click clear all caches.

You will now have a different .tpl.php page for each page type you would like.

From a users point of view this (In my opinion) is much easier for them to grasp when they are adding pages to the site that they are adding a page for a specific type of content.

This is my first post hope there are many more, thanks everyone for all the help. Scott

The below link will be helpful

http://mydons.com/how-to-theme-nodes-of-specific-content-type-in-drupal-7/

It seems that this is a little overkill when we simply need to make a node template for the comment type. For example for the node type blog, assuming the machine name is blog, the node template would simple be node--article.tpl.php.

Here you can display and access anything in the node by dumping the $node object (using dpm($node) or whatever way you want to dump the object).

Here is a link to the node template file: http://api.drupal.org/api/drupal/modules%21node%21node.tpl.php/7

Add this code in template.php in the Bootstrap Subtheme

//page--content-type-name.tpl.php
function MY_BOOTSTRAP_SUBTHEME_preprocess_page(&$vars, $hook) {
if (isset($vars['node']->type)) {
$vars['theme_hook_suggestions'][] = 'page__' . $vars['node']->type;
}
}

Add the below code in the template file

function my_theme_reprocess_page(&$variables, $hook) {
if (isset($variables['node']->type) && !empty($variables['node']->type)) {
$variables['theme_hook_suggestions'][] = 'page__node__' . $variables['node']->type;
}
}

I am trying to know abt priorities of tpl files in themes, from this post i got what exactly hook suggestions at drupal..

This code works for me, when viewing or editing a content type, but when add a new one it doesn't.  I can't figure out what to name the template.  The URL is http://domain.com/node/add/content-type-name/436
