Using templates | | |
Anyone feeling like they want to give me a 101 on general template handling in
PHP?
My history
I used to be a Roxen guy, where you could define your own HTML-tags, so that
"<foo />" could be set by "<define tag='foo'>Hello World</define>" so every
time you use the tag <foo /> it would be parse and replaced with "Hello World".
Naturally, within a <define>, any kind of roxen code can be used.
Today
I am using "php_value auto_prepend_file" and "php_value auto_append_file" to
insert a header and foot script to create the layout of a page, and function()
in required files to make small scriptlets such as headline() and stuff like
that.
The problem
With PHP, I can't make containers. Not real ones anyway. In Roxen, I could have
done this:
<define container="headline">
<span class="headline">
<contents />
</span>
</define>
So <headline>Hello!</headline>
Would become <span class="headline">Hello!</span>
You get the idea.
Now, with PHP, the above would be:
function headline($headline){
print "<span class='headline'>$headline</span>";
}
But the obvious problem is when you want to use this function for more than
just a small string - you might want a big block of HTML and PHP code to be
contained inside a HTML table with a border - for example. In Roxen this would
be done by:
<square>
Big old chunk of text, html, mysql, rxml or whatever.
</square>
And the end result would be that big chunk of text surrounded with the code of
a table. This is useful for lots of things, bbut generally for framing things
in different ways - mainly for news-boxes on pages
Currently, Im am doing this in php this way:
<?=square("start") ?>
Big old chunk of text, html, mysql, rxml or whatever.
<?=square("end") ?>
But that's just ugly code and cumbersome.
Now to the point (finally!) - How does templating workm, and could it be used
to accomplish what I am trying to do here? I am aware of 'Smarty' and I have
downloaded it and played with it, but it was just a difficult concept to grasp
for me (yeah,. so call me stupid) and it did caching and had compiled scripts
and whatever. Isn't there a smpler solution?
Nayway, I'm grateful for any help in this area. :)

You might try patTemplate or simply use XSLT

If you want simple, I guess you can turn on output buffering then pass
everything through strtr(). Example:
$my_own_tags = array(
'<headline>' => '<span class="headline">',
'</headline>' => '</span>',
....);
echo strtr(ob_get_clean(), $my_own_tags);

Just want to mention that i usually include the contents, not the "borders":
<div id="submenu">
<? include submenu.php?>
</div>
This gives the benefit of updating easily the contents that are all over the
site. And when those contents are php, they speculate form variables and
change automatically according to them. | | | | re: Using templates

Sorry, that won't help in my situations.

Ok, sounds interesting - exactly how do I do it? Is it called at the very last
in the script or could I call it in the beginning? Could it be used with
external files? Like so:
## headline.txt
<span class='headline'>
&contents; <- To be replaced somehow.
</span>
## init.php (loaded every time - before the current page)
???
## index.php:
<headline>Hello!</headline>
Looking at php.net, it seems ob_get_clean() fetches the current buffer, so
executing it in the beginning of the script won't do much. Hmmm...

You would call ob_start() in init.php and strtr(ob_get_clean(), ...) in the
file that's included at the end, or you can give a callback to ob_start()
which gets called automatically when the page is flushed. Example
init.php:
function add_custom_tag($name, $content) {
global $custom_tags;
$custom_tages["<$name />"] = $content;
}
function add_custom_container($name, $start, $end) {
global $custom_tags;
$custom_tages["<$name>"] = $start;
$custom_tages["</$name>"] = $end;
}
function replace_custom_tags($buffer) {
global $custom_tags;
return strtr($buffer, $custom_tags);
}
load_tag_definitions('custom_tags.txt');
ob_start('replace_custom_tags');
For the tag definitions, you can use Roxen's syntax with something like
this:
function load_tag_definitions($filename) {
$def = file_get_contents($filename);
if(preg_match_all('!<define tag="(.*?)">(*.?)</define>!s', $def,
$matches)) {
$tags = $matches[1];
$content = $matches[2];
foreach($tags as $index => $tag) {
add_custom_tag($tag, $content[$index]);
}
}
if(preg_match_all('!<define container="(.*?)">(*.?)<content
/>(*.?)</define>!s', $def, $matches)) {
$tags = $matches[1];
$start = $matches[2];
$end = $matches[3];
foreach($tags as $index => $tag) {
add_custom_container($tag, $start[$index], $end[$index]);
}
}
}
