TYPO3 4.3 Multimedia Cookbook

Chapter 2. Managing Digital Assets

In this chapter, we will cover:

  • Setting up a file structure

  • Setting up a filemount

  • Setting up rights for backend users

  • Setting up FTP access

  • Setting up a category tree

  • Creating a frontend upload form

  • Debugging code

  • Creating frontend user groups

  • Creating frontend users

We will also look at digital asset management, why you may need it, and how to use it in TYPO3.

Setting up a file structure


When starting a new site, one needs to decide on the file structure that will be used. The specific directory tree will probably depend on the application and the type of information stored in those folders. But, there are certain ways by which TYPO3 can help you sort files, which should give you a guide as to how you should lay out the file tree.

Getting ready

First, you need to decide on the approach to the file structure.

  • By user

    This is a common layout that's used in multiuser environments. Filemounts can be set up to limit the user to just a specific folder. We will examine how this can be done in the recipe Setting up rights for backend users.

  • By user group

    This is similar to the previous setup, but more functional in team environments, where several users might share a job function. Filemounts can be set up for a group (content editor, publisher, videographer, and so on), and assigned to several users, who would then share access to files.

  • By date

    If you have...

Setting up a filemount


Filemounts limit a user to just a specific folder tree under the fileadmin directory. This is good for security purposes, as well as general usability in a multiuser environment. Instead of browsing through all the files available in the system, the user can be directed to just the files he/she needs to manipulate.

Getting ready

To set up filemounts, you must have a directory structure in place. For the recipe that follows, we will assume that we decided on a "by user" tree (see recipe Setting up file structure).

How to do it...

  1. 1. Use the List module and go to the root page of the site (PID: 0, usually the topmost node).

  2. 2. Click the Create New Record button.

  3. 3. Choose Filemount. You should see the following screen:

  4. 4. Fill in the required Label field. The Label field allows you to name the filemount to something you would remember, and could pick out from a list and know where it points.

  5. 5. Fill in the required Path field. The path refers to the file system path to the directory...

Setting up rights for backend users


In this recipe, we will create a backend user, who will be able to log into TYPO3 and have limited rights, which would allow him or her to do his/her job without causing any deliberate or accidental damage to the system.

Getting ready

To limit a user to his/her folder, he/she must have a configured filemount. Make sure you have completed the Setting up a filemount recipe, and have correctly set up at least one filemount.

How to do it...

  1. 1. Under the Admin tools | User Admin module, click the button to create a new user.

  2. 2. Under the General tab, fill in the required fields—Username and Password.

  3. 3. Enter the user's name and e-mail address.

  4. 4. Under the Access Rights tab, select the modules that you would like the user or user group to see in the left frame.

  5. 5. Under DB Mounts, select the top page of the branch to which the user should have access.

  6. 6. Under DB Mounts, make sure to also select the Media SysFolder that was created by DAM extension, as that is where...

Setting up FTP access


There are times when you need to allow FTP access to your users. There are plenty of FTP daemons to make it easy. However, you would have to set up individual users, and configure their restricted access. It is much better to leverage the backend user configuration already in TYPO3, and use it to provide basic FTP access to the same files accessible in the backend.

Getting ready

We will use Pure-FTPd daemon to provide FTP access. The steps below assume you are on a Debian system, and Pure-FTPd is available in package repositories. If its not, you would need to compile it from source.

How to do it...

  1. 1. Install Pure-FTPd, along with the MySQL authentication module.

    Shell> apt-get install pure-ftpd-common pure-ftpd-mysql
    
  2. 2. Open the MySQL configuration file (by default in /etc/pure-ftpd/db/mysq.conf). Edit the following values:

    • MYSQLServer: Point it to your MySQL server IP, or localhost

    • MYSQLUser: DB username

    • MYSQLPassword: DB password

    • MYSQLDatabase: Name of the DB that TYPO3...

Setting up a category tree


Files can be sorted by categories. This provides another layer of classification for media assets, allowing them to be organized and grouped without changing their physical location. A common setup is to arrange the physical storage as we have by user or by user group in order to make rights assignment easy, but setup a category tree by subject of the media content, to group similar files together. Here is an example:

Getting ready

Category support is built in to DAM, but to ease category management you should install the extension dam_catedit. This extension provides full management capability optimized for DAM categories. We've covered how to install extensions in Chapter 1 in recipe Installing needed extensions, so refer back to it for a detailed description.

Once you have installed the extension, the Categories module will appear under Media.

How to do it...

  1. 1. Go to the Media | Categories module.

  2. 2. If there are no categories in the system yet, you will see only...

Creating a frontend upload form


In this recipe, we will create a simple extension, which would add a form to the website, and let users upload files. Files will be indexed by the DAM.

Getting ready

We will create the extension from scratch, and if you want to follow along, make sure to install Kickstarter to create the framework. Otherwise, you can download the finished extension but make sure to review the How it works... section to understand what happens in the code.

How to do it...

  1. 1. Under the Extension Manager, select Create new Extension. If you don't see the option, Kickstarter has not been installed.

  2. 2. Under General Info, click the plus icon (+), and fill in the basic information. Name the extension User Upload.

  3. 3. Under Dependencies, enter dam. When the extension is installed, Extension Manager will check the presence of DAM, and proceed only if DAM is present and installed. Likewise, Extension Manager will not allow DAM to be uninstalled as long as our extension is still installed...

Debugging code


In the Creating a frontend upload form recipe, we went through the execution of the script line by line. When writing your own code, you would probably want the same benefit, giving you the ability to go through execution line by line, and seeing exactly what is happening. This functionality is provided by debuggers.

There are several debuggers available for PHP for any platform. Most debuggers are bundled with an IDE, so that you can use them together. For example, NuSphere PhpEd comes with DBG debugger, which we will make use of in this recipe.

Getting ready

This recipe assumes you have NuSphere PhpEd installed on your Windows computer. If you don't skip ahead to the There's more... section for general tips on using debuggers, which you can then apply to a debugger of your choice.

Note

For more information about NuSphere PhpEd, go to http://www.nusphere.com/.

How to do it...

  1. 1. Go to C:\Program Files\nusphere\phped\debugger\server (or equivalent installation path).

  2. 2. Select the...

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
