working with smarty[RESOLVED]

Zak Zillion · Post by **Zak Zillion** » Sat Apr 23, 2011 10:38 am

Hey everyone, So I working with smarty to build a game (i'll be posting it in the Project Showoff Tier I later). This is my first time using smarty and it is giving me some trouble. Most of the game will be played through play.php, it is a text based MORPG were you move through the game and the db generates almost the whole page. Right now I am wanting the db to list all of the merchants and healers in the area through an array but smarty doesn't want to work with me for some reason. If someone could help me it would be awesome!

play.php

Sorry that there have been no responses on this so far, and sadly, I know little to nothing about Smarty as well. The general community consensus has been that it is typically overkill for the types of projects we do, since its main purpose is facilitating a non-destructive workflow between designers and developers on the same team, and well...we usually play both roles on our own projects. Have you tried asking in the Smarty forums? Surely you could get a fast answer there.

Thank you for the response Jack, I have decided to convert back to just using PHP. I found that the syntax was was actually hindering me and it was annoying to not be able to see a page without saving it to the server, which would sometimes be down. So again thanks for the response and feel free to delete this topic.

I initially looked into Smarty as well, but decided not to use it. It really seems to be geared towards large team projects that are split into design and development departments with little cross-training.

I'd recommend using a framework such as CakePHP or Code Igniter if you're looking to develop your game in a slightly more modular way.
Smarty is, as Jack said, very dense as a framework (its more of a Template Engine). It can be actually very nice when you get the hang of it.

An easier alternative (and by no means thought lesser of) is a true MVC framwork.
If you're new to the whole MVC (Model View Controller) Architecture, I'd suggest using Code Igniter, its quite a simple framework.
Cake on the other hand is slightly more complex in terms of the concepts behinds its working, however Cake in my opinion is a better than Code Igniter. It offers more libraries, helpers etc.. as well as having some awesome Associative Model support (for database stuff). Its bigger and a little more challenging to get your head round at first BUT once you get your head around the whole idea of MVC you'll love it so much

If you start with Cake and find it too difficult, try Code Igniter, its where I started

I agree. MVC is the best way to manage and develop mid-range and larger web applications (and that includes games). If you are wanting a template system like ASP.NET's Master Pages, where you make a design one time with content areas, and then reference it for each individual page you make (or "view" in the case of MVC), you can use PHP's include() function to insert other PHP files into your page. What I do is I make a folder to hold my site's template, and then inside that folder I make several files such as header.php, footer.php, nav.php, etc. Each one just has opening and closing PHP tags, and between those tags I just have an echo statement that echoes out the HTML for the page portion it should contain (for example, the header.php file would have the Doctype, head tags and contents, and so on down to the nav section). This way you can put your unique page content between these include() calls which will form your page template around that unique page content.

This is an easy system to implement, and although it may not be quite as elegant, it does the #1 thing that most individual developers want Smarty for: page templating. And it doesn't make you use a heavy code library or completely change how you code your files!

I looked into code igniter and cakephp. Both seemed good but im a little gun shy right now after smarty, I think I will stick with just php for now. On my next project I think I will look into cakePHP it looked pretty good. Thanks guys for the help with this.

a little late i know, but hell am i gunna miss out on a smarty topic

Smarty is a templating system through and through. I really wouldnt recommend it for a game UNLESS you wanted to offer different styles, ie... differnt layouts for different races etc. It is much easier to use a templating system, rather than work yourself into a knot getting your pages set out to handle differnt layouts.

However, saying that. Since using smarty, i have found it much easier to code because the layout and backend code is seperate, thus making it neater and easier on the eyes (unless you get deep into loops lol, they are pigs!! trust me lol). But basic smarty syntax practically mimics standard code syntax.

i.e

php:

if($x == $y)
{

}

smarty:

{if $x == $y}

{/if}

php

for($x=0; $x<$y; $x++)
{

}

smarty

{for $x=0 to $y}

{/for}

Obviously things differ depending what you want to do, but it is my opinion that it is by far much easier to work with templates rather than it all crammed into a single page.

anywho lol, i saw a smarty topic, i said my bit :p

I know this is off-topic, but since this is an older topic, I figured I would mention it. That is a neat idea! Of course it would be a crapton of extra design work, but it would be interesting to have a totally different UI for each race, or perhaps every class. Maybe the form could be different through alternate CSS sheets for each race to reflect the feel of each race's backstory, and the function of the UI could be different for each class to reflect the way the class plays, which would be done through dynamic HTML modifications.
