Template Parser & Associated Questions

#1
[eluser]Gwarrior[/eluser]
I've been using CodeIgniter for well over a year now and somehow I've managed to never notice the built-in Template Parser class. After taking a look at it, it's like Smarty built-in!

So my question is, how many of you swear by it and are there any significant performance drops when using it?

Thanks!

I've used it on some project when it suited my needs. It is rather lightweight. I didn't notice any mentionable performance drops. Even when parsing 40 or 50 pages (A4 size html for printing) it is still fairly fast.

I personally would love to use it but for me it never suited a project. If it would just include a simple if / else then I would imagine it would get a lot more use.

I use if/else statements with the parser.
<code>
if("{some_var}"!="")
</code>

Works like a charm.

And yes, this is php not templating... but hey, it works.

Very cool. I never thought of doing it that way. Big Grin

"Smarty was a friend of mine. CI Template Parser, you are no Smarty." - WRT, Sen. Althouse

don't make the mistake thinking CI Template Parser is like Smarty; it's not.

i've used both and now i just use PHP native template style. it's pretty easy - it's even easy to explain. if you use short tags, and you get all of PHP should you need it. with Smarty I was always twisting myself up in smarty-syntax, with the template parser, i was always "prepping" things to get them perfectly arranged in the controller.

here's a rundown of "PHP native template" (copied from this old post http://ellislab.com/forums/viewthread/102566/#517530:
-------------------------------
just turn on short tags and tell the client you found a good template parser. i wrote the documentation for you below. :-)

the syntax is very simple (and supports what you want - if and foreach)):
&lt;? to start template tag,
?&gt; to end template tag,
to display template variable use echo keyword,

example: &lt;? echo $variable ?&gt;

&lt;? if($variable_to_test): ?&gt; to start conditional,
&lt;? endif; ?&gt; to end conditional,

example: &lt;? if($is_true): ?&gt;

&lt;? foreach($list as $item): ?&gt; to start loop,
&lt;? echo $item ?&gt; inside loop
&lt;? endforeach; ?&gt; to end loop

in the controller...(developer will edit this)
Code:
function template()
    {
        $d['title']='this is a title';
        $d['heading1']='this is a heading one';
        $d['variable']='this is a variable.';
        $d['rand_variable']='this is a variable to show at random.';
        $d['show'] = rand(0,1);
        $d['list'] = array('list item 1', 'list item 2', 'list item 3');
        $this->load->view('tester',$d);
    }
in the view (user will edit this)
Code:
&lt;html&gt;
&lt;head&gt;
    &lt;title&gt;&lt;? echo $title ?&gt;&lt;/title&gt;
&lt;/head&gt;
&lt;body&gt;

<h1>&lt;? echo $heading1 ?&gt;</h1>

&lt;? echo $variable ?&gt;<br />

&lt;? if($show): ?&gt;
    &lt;? echo $rand_variable ?&gt;
&lt;? else: ?&gt;
    This will print if the random variable is not shown on this page load - refresh page.
&lt;? endif; ?&gt;

<br />

<ol>
&lt;? foreach($list as $item): ?&gt;
    <li>&lt;? echo $item ?&gt;</li>
&lt;? endforeach; ?&gt;
</ol>

&lt;/body&gt;
&lt;/html&gt;

EDIT: you could even do it with short tags
Code:
&lt;html&gt;
&lt;head&gt;
    &lt;title&gt;&lt;?=$title?&gt;&lt;/title&gt;
&lt;/head&gt;
&lt;body&gt;

<h1>&lt;?=$heading1?&gt;</h1>

&lt;?=$variable?&gt;<br />

&lt;? if($show): ?&gt;
    &lt;?=$rand_variable?&gt;
&lt;? else: ?&gt;
    This will print if the random variable is not shown on this page load - refresh page.
&lt;? endif; ?&gt;

<br />

<ol>
&lt;? foreach($list as $item): ?&gt;
    <li>&lt;?=$item?&gt;</li>
&lt;? endforeach; ?&gt;
</ol>

&lt;/body&gt;
&lt;/html&gt;
