This implies that PHP code is application logic, and is separated from the presentation. Templates: Two camps of thought When it comes to templating in PHP, there are basically two camps of thought. The first camp exclaims that "PHP is a template engine". Although this approach is fast from a pure script-execution point-of-view, many would argue that the PHP syntax is messy and difficult to maintain when mixed with presentation. PHP works well for programming, but not so well for templating. The second camp exclaims that presentation should be void of all programming code, and instead use simple tags to indicate where application content is revealed.
Here we will also be using Poedit to create translation files. Structure Types of files There are three files you usually deal with while working with gettext. Domains There are some cases, in big projects, where you might need to separate translations when the same words convey different meaning given a context. In those cases, you split them into different domains. In Symfony projects, for example, domains are used to separate the translation for validation messages.
Locale code A locale is simply a code that identifies one version of a language. It is defined following the ISO and ISO alpha-2 specs: two lower-case letters for the language, optionally followed by an underline and two upper-case letters identifying the country or regional code.
For rare languages , three letters are used.
For some speakers, the country part may seem redundant. Directory structure To use Gettext, we will need to adhere to a specific structure of folders. First, you will need to select an arbitrary root for your l10n files in your source repository.
Plural forms As we said in the introduction, different languages might sport different plural rules. However, gettext saves us from this trouble once again. When creating a new. When calling Gettext in code, you will have to specify the number related to the sentence, and it will work out the correct form to use - even using string substitution if needed. Plural rules include the number of plurals available and a boolean test with n that would define in which rule the given number falls starting the count with 0.
When calling out Gettext to do localization on sentences with counters, you will have to give him the related number as well. Gettext will work out what rule should be in effect and use the correct localized version.
You will need to include in the. It describes the file encoding, plural forms and other things that are less relevant. The second section translates a simple string from English to Brazilian Portuguese, and the third does the same, but leveraging string replacement from sprintf so the translation may contain the user name and visit date.
The last section is a sample of pluralization forms, displaying the singular and plural version as msgid in English and their corresponding translations as msgstr 0 and 1 following the number given by the plural rule.
The plural forms always have two msgid singular and plural , so it is advised not to use a complex language as the source of translation. Discussion on l10n keys As you might have noticed, we are using as source ID the actual sentence in English. That msgid is the same used throughout all your.
FEATURES: The template engine has many features for presentation that would otherwise need to be developed, tested and maintained in your own application code. Tags also mask the complexity of PHP statements. Smarty insulates the templates from PHP, creating a controlled separation of presentation from business logic.
Smarty also has security features that can further enforce granular restrictions on templates.
Templates also restrict what can be put in a template. PHP makes it too easy to add code into templates that doesn't belong there. You could teach designers the rules of application design, but this should be unnecessary now they are developers!
The PHP manual is intended for developers. Designers would only need a small fraction of this manual, and it doesn't make it easier for them to find what they need.
Smarty gives web designers exactly the tools they need, and gives developers fine-grained control over these tools. Numerous features are also available for presentation such as template inheritance, which maximizes template re-use and streamlines organization. Implementation is Important Although Smarty gives you the tools to make a clean separation of presentation from application code, it also gives you plenty of room to bend those rules. A poor implementation i. The documentation does a good job of indicating what things to watch out for.
Also see the Best Practices section.
What does Smarty look like, and how do I use it? How does it work?
Under the hood, Smarty compiles copies of the templates as PHP scripts. This way you get the benefits of both template tag syntax and the speed of PHP.
Compilation happens once when each template is first invoked, and then the compiled versions are used from that point forward. Smarty takes care of this for you, so the template designer just edits the Smarty templates and never has to manage the compiled versions.
This approach keeps the templates easy to maintain, and yet keeps execution times extremely fast. Template Inheritance Template inheritance is new to Smarty 3, and it's one of many great new features.
Before template inheritance, we managed our templates in pieces such as header and footer templates. With template inheritance, instead of including other templates we maintain our templates as single pages. We can then manipulate blocks of content within by inheriting them. This makes templates intuitive, efficient and easy to manage.
See Template Inheritance for more info. There are a couple of good reasons. It is perfect for computers, but horrible for humans.
Smarty is about being easy to read, understand and maintain. Template Security Although Smarty insulates you from PHP, you still have the option to use it in certain ways if you wish. Template security forces the restriction of PHP and select Smarty functions.
