Dupal 7结合了50多个模块的功能

AHAH helper

Allows Drupal modules to implement AHAH/AJAX functionality without touching JavaScript. Entirely covered by the new AJAX framework in D7, which is based on Earl Miles' CTools.

Autoload
Allows Drupal modules to lazy-load any class that has not been loaded yet. A major performance improvement in Drupal 7, and the only part of the Registry™ that was introduced earlier, but later removed from Drupal 7.

Auto Menu Title
AutomaticMenu
Auto Menu

When creating new content, Drupal 7 automatically takes over the title of the content as menu link title, while still allowing you to alter it.

Admin:hover
Block edit

One of the improvements that will have a major impact on Drupal's evolution and success in the future: Edit links on everything. The new Contextual links module in Drupal 7 allows you to manage page elements from the page you are looking at, i.e. you have direct access to "Edit" and "Delete" pages for content, or "Configure" pages for blocks, "List links" for menu blocks, etc. This applies to all elements that are integrating with Contextual module.

Admin Role

More or less requested since like ever, Drupal 7 finally ships with a sane implementation of an administration role. It's based on regular Drupal user roles, and you can configure any user role to be that administration role. Effectively, any new permissions (and only new) are automatically granted to the configured administration role (if any). You are therefore still able to remove permissions from the role.

Block Node Visibility

Ever wanted to display a block on certain node types only? Drupal 7 allows you to do so. Additionally, the block visibility integration has been de-cluttered to some extent, so as to allow other modules to enhance the visibility settings more easily. (Passing the 4th "code freeze" phase was a bit too late to clean this API up properly... ;)

404 Blocks

404? What's that, you ask? Not the content I expected on your site? Right! Drupal did not provide any useful information or pointers for totally lost users on "404 Not found" pages previously. Drupal 7 now retains the regular block regions.

Content Construction Kit (CCK)

CCK is in Drupal 7. But not really. The reality is that Drupal 7 introduces the paradigm of "fields". Got that? Fields can be attached to almost everything. You can add fields to nodes, users, taxonomy terms, and any other fieldable "entity" that exists. You could potentially add a taxonomy term to private messages (if privatemsg will implement a message as entity). You can attach any field to any entity. And it even allows to get weird: You can add a taxonomy term field to a taxonomy term. Insane? Insane!

Checkbox Validate

Users have to confirm an optionally required checkbox, such as terms of use or any other usage agreements? Broken in Drupal 6 and below. Drupal 7 finally allows you to make a checkbox required.

Comment Display

Comments on a node were rendered in a obscure fashion in previous Drupal versions: Within a node, but not really within it. Somewhere in between, but also not part of the page. So what? Drupal 7 finally renders comments in a way they are customizable for your theme.

Site Configuration Permissions

Who is an administrator, and who's not? Who can change settings, who can manage modules, who can manage themes? Who can set the site offline, and who can access it if it's offline? Previous Drupal versions summarized all of that in the "administer site configuration" permission. Drupal 7 allows you to grant many administrative permissions more granularly.

Content Taxonomy
Field Taxonomy
Term fields
Taxidermy

In previous Drupal versions, Taxonomy terms (or simplified: categories) could be assigned to content only. In Drupal 7, you have a taxonomy field, which can be attached to any entity. Furthermore, a taxonomy term is a proper entity now, coming with solid API hooks.

DBTNG
Transaction

Drupal 7 implements an entirely revamped support for databases. Database Layer: The Next Generation (DBTNG) allows Drupal to consistently work with any kind of database. Modules are finally able to properly alter almost any database query, and we can roll back all changes from a "transaction", in case something went wrong during the entire operation.

Elements
Element theme hook

When requesting a particular page, the callback function in charge for that page returned a HTML string in previous Drupal versions. Almost impossible to alter or customize in any way. In Drupal 7, almost any content that can be rendered, is returned as a "renderable array". If you know the array structure of Drupal forms, you may get the idea. This allows us to consider any element on a page as atomic, alterable, and themeable element. Especially the themeable part matters, if you ever wanted to change the output of something, anywhere.

File field
Upload element
Upload preview

Upload module has been removed from Drupal core. And replaced with a much more generic file field. Providing previews after uploading, supporting very large file sizes (on good hosting providers), and of course, having all the goodness of any other field in Drupal 7.

Filter Default
User Default Filter

Sick of selecting the text format for your content all over again? Drupal 7 now allows you weigh text formats, so as to pre-select a certain text format for a certain user role. Text format? Yes, "input format" is a term of the past.

Image
Image API
Image Cache
Image Field

Drupal 7 is the first Drupal release with native image support. You get an image field. And - you guessed it - you can add an image field to any entity. On top of that, you can configure image styles - which allow you present the same image in a different size/scale/fashion in different locations. Additionally, Drupal developers can now use much more advanced functions to process images.

Input Format Permissions

Permissions to use a text format can now be granted on the regular user permissions page, on which all other Drupal permissions are configured. Good for security.

jQ
jQuery Plugin Handler (JQP)
jQuery plugin manager

Drupal 7 allows to bundle multiple JavaScript and CSS files into a "library", which can be loaded by modules in one shot. This covers a lot of use-cases for jQuery stuff. It purposively does not cover external libraries (i.e. code that is not hosted nor shipped with a module), but the Drupal community is already shaping a solution in the Libraries API project.

jQuery Cookie

The jQuery Cookie library is part of Drupal 7 core now. It allows Drupal modules to store and retrieve data from browser cookies via JavaScript. For example, when repeatedly posting a comment on a Drupal 6 site, your user information is already filled in. That information is stored in a browser cookie.

jQuery UI

Drupal 7 brings you the awesomeness of jQuery User Interface. Drupal core doesn't really use it, but there's still a major issue almost ready to be committed (since like months), which at least allows contributed Drupal modules to leverage the power of jQuery UI very easily.

JS Alter

Modules and themes are able to properly alter all JavaScript that is added to a page in Drupal 7.

Login Security

What happens after 5 failed login attempts? Nothing. Meet Drupal 7: Built-in brute-force login protection.

Menuless Node Type
Menu Settings per Content Type

Does it make sense to have Devel's menu as option for the menu link in the content form? Drupal 7 allows you to select the menus that should be available per content-type. Additionally, all administrative menu links are now contained in a separate menu, so all of those annoying links don't get in your way.

Node Preview by Content type
Preview

Should previewing a content be required? Is it optional? Or is it entirely pointless? Drupal 7 allows you to configure the "Preview" button behavior per content-type.

Permissions API

Previously, Drupal developers had not really a way to grant, revoke, or change the permissions for a user role. Drupal 7 now ships with a solid user roles and permissions API to do just that.

Plugin Manager

Install and update modules and themes from within Drupal? On-site? Drupal 7 allows you to do that, in a secure way.

Poor man's cron
Drupal Queue

Most probably the #1 problem for novice Drupal users: "cron". Drupal tells you to set it up. "WTF is a cron?" Drupal 7 allows to automatically run cron (and yes, this feature can be disabled easily). Somewhat related, Drupal 7 also provides a queue system now.

RDF

The semantic web is the search engine optimization of the future. Drupal 7 gets ahead of the entire industry by implementing full support for RDFa all over the place. This means that bots, spiders, and crawlers can easily classify and identify the content on your pages, and precisely figure out the topic and relationship of every single page on your site. Most probably, they will even know more about your content than you do.

Seven

Like it or not, Drupal 7 ships with a dedicated administration theme.

Simpletest

A major change for Drupal 7 is the introduction of automated tests for all functionality. Almost every change that went into Drupal 7 had to be covered by tests. In turn, this means that the first stable release of Drupal 7 will be the most stable release of Drupal in its entire history. And in turn, this means that you can expect a very stable Drupal core and much less bugs. Additionally, contributed modules are slowly catching up on adding and writing tests.

Archive::Tar

Mainly here to extract downloaded modules and themes via Plugin Manager, but also usable by all modules: Drupal 7 allows to extract tar archives.

Taxonomy Delegate
Vocabulary Permissions

You have multiple vocabularies? And certain users should be able to alter/administer certain ones? Drupal 7 allows you grant user permissions to do just that.

Token

Drupal 7 supports simple string replacements via tokens. The heavily changed and advanced version of tokens in Drupal 7 support recursive, lazy-loading replacements. For example, [node:title] is replaced with the title of a content, and [node:author:name] is replaced with the user name of the author of a content.

URL alter

In Drupal 6 and below, modules like Domain Access and others were incompatible with any other of those modules, or required you to add custom code to settings.php. Drupal 7 allows multiple modules to alter both the incoming and all generated URLs without any hacks.

User Cancellation
User Delete

Privacy of data matters. Professional sites allow you to cancel your account. At any time. But does Drupal? Yes: Drupal 7 enables you to allow your users to cancel their own accounts. In different and even extensible ways. Whether you need to retain all user data due to legal reasons, or whether you need to delete all user data due to legal reasons, or whether you need to do something in between: Drupal 7 supports you.

Vertical Tabs

Forms in Drupal can get very long. Especially when containing fieldsets. But how often do you really change something in those fieldsets? Drupal 7 introduces the new pattern of vertical tabs. Exclusively for entirely optional form elements, i.e. stuff you can happily ignore when submitting a form in Drupal. A major usability improvement that benefits all Drupal users.

View unpublished

It's weird that you cannot view your own content after submitting it. At least in some use-cases, that's desirable. Drupal 7 allows you to configure whether users should be able to view their own unpublished content after submission.

Canonical URL
Shortlink

If you know some basics about search engine optimization, then you have probably heard of duplicate content. Due to the way URL aliases work in Drupal, many sites are exposing the same content under different URLs - on the system path and on the URL alias(es). Drupal 7 helps you to avoid duplicate content penalties by letting search engines know about the canonical URL of a content.

Date Timezone

In Drupal 6 and below, Drupal implemented a custom timezone handling. Starting with Drupal 7, Drupal relies on PHP5's built-in timezone handling, which provides you many more timezones, and most importantly, support for daylight saving time (DST).

Documentation

Almost the entire API and hook documentation has been moved into dedicated .api.php files in Drupal core. Drupal developers can access that information locally, and the file contents are used 1:1 for Drupal's online API documentation.

Edit term
Taxonomy Intro

Ever wanted to edit a taxonomy term when looking at its page? Drupal 7 now provides you a tab. Additionally, the taxonomy term description has a text format assigned now, allowing you to use a client-side editor for it.

File API
Storage API

Drupal 7 ships with an entirely overhauled API for handling and processing of files. Drupal 7 also introduces stream wrappers from PHP5, allowing you to store and access files in many different ways and locations, even remotely. Drupal 7 is the first Drupal release with a proper separation between public and private filesystem, and you can use both at the same time.

jQuery Form Update
Wysiwyg API CCK Integration
TinyMCE AHAH Integration
TinyMCE Drag and Drop Integration

As a result of the community's joined effort on the Wysiwyg module, Drupal 7 contains many improvements that will allow a better integration of client-side editors. Lessons learned: Module duplication sucks. Only if Drupal developers and users are joining forces, we can improve the overall situation. (And no, Drupal 7 does not ship with an editor. And having the experience as one of the Wysiwyg module maintainers, I'm highly opposed to ever do that.)

Secure Password Hashes (phpass)

Starting with Drupal 7, all passwords of users that are stored in Drupal's database are additionally "salted", so as to make it harder to reverse-engineer the user's unencrypted, original, plain-text password.

Simple CDN
Absolute src
Parallel

The new File API and handling of page requisites (JavaScript, CSS) in Drupal 7 allows Drupal modules to alter the URLs of files. This allows the Drupal community to work on a dedicated CDN integration solution to boost page loading performance.
