More often than not, templates in a project share common elements, like thewell-known header and footer. Using this helper, the static HTML code canbe placed in a layout file along with “slots”, which represent the dynamicparts that will change on a page-by-page basis. These slots are then filledin by different children template. In other words, the layout file decoratesthe child template.

Displaying Slots¶

The slots are accessible by using the slots helper ($view['slots']). Useoutput() todisplay the content of the slot on that place:

The first argument of the method is the name of the slot. The method has anoptional second argument, which is the default value to use if the slot is notavailable.

The _content slot is a special slot set by the PhpEngine. It containsthe content of the sub-template.

If you’re using the standalone component, make sure you registered theSymfonyComponentTemplatingHelperSlotsHelper:

Extending Templates¶

The extend() method is called in thesub-template to set its parent template. Then$view[‘slots’]->set()can be used to set the content of a slot. All content which is not explicitlyset in a slot is in the _content slot.

Note

Multiple levels of inheritance is possible: a layout can extend anotherlayout.

For large slots, there is also an extended syntax:

So as we’ve promised here goes more slides for online viewing:

1. Symfony 2 by Fabien Potencier

It’s long one but contains great information “where will be moving symfony in next 1-2 years”.
Frankly, I’m a bit confused b/c I feel that symfony 2 wont be compatible with 1.x branch. I did not hear that but I dont think after all these major changes compatibility is still possible.

2. Sympal – The flexible Symfony CMS by Jonathan H. Wage

We’ve already heard about sympal (i read about it in twitter from goyello’s guy) and had a quick look into that but I never thought I’d be interested to use one more self-written CMS. I must say I was wrong. After I’ve seen these slides I understood a few things. First of all Sympal contains whole bunch of new plugins sfSympalXXX which can be used separately in own projects. Also it’s really more like Drupal than like WordPress or Joomla 🙂
Sympal is good source for anyone who is planning to use YUI in his symfony projects. Also it’s simply good source for anyone who want to improve his symfony skills (I wont recommend it for beginners).

What I dont like is “slots” (it’s not sympal problem/idea though). Not sure maybe I just did not see good slots realization but I really preffer Joomla’s way of publishing/ordering modules.

3. What’s New In Doctrine by Jonathan H. Wage

Symfony 1.4 Include_component Slotted

What is really clear from these slides – everything is much simpler and better in Doctrine 2.
So I understood – it’s time to start using doctrine instead of propel 🙁
Sorry Propel I loved you sooo much. You were great and I’ll be missing you but you were really slow sometimes and needed to much server memory 🙂

Symfony 1.4 Include_component Slot Car Bodies

Did we miss any interesting slides from conference? Yes we did.. there were lot of them in French and unfortunately we dont speak French (we wish we can). Hopefully someone provides us English versions so we can review them as well. Would be really great.

Have a great weekend symfonians!
