Assalamu'alaikum wr. wb.
Hi,
I just add some new feature to template, basically it let's you
add <!-- IF var -->...<!-- ELSE var -->...<!-- ENDIF var -->
and let the template do the job like cpp
#ifdef var
...
#else
...
#endif.
I also integrate some fix's that spread among mailing list archive.
Oh I almost forgot, now you could also set filter (another preg)
on template so that you could replace the final bits of your template.
Just take a look at set_filter and subst.
I hope it would be usefull.
The patch is in the attachment.
Here's my testbed code:
-----------------------------------------------------------
<?php
include("template.inc");
//header("Content-Type: text/plain");
$tpl = new Template("./", "keep");
$tpl->set_file("simple", "simple.ihtml");
$tpl->set_var("Title", "Testing New Template");
$tpl->set_var("self", $PHP_SELF);
$tpl->set_var("e-mail", "me <email protected>");
$tpl->set_var("ONE", $one);
$tpl->set_var("TWO", $two);
$tpl->set_var("THREE", $three);
$tpl->set_var("SHOW_FORM", !$hide);
$tpl->parse("out", "simple", FALSE, TRUE);
$tpl->p("out");
?>
-----------------------------------------------------------
Here's the simple.ihtml template:
-----------------------------------------------------------
<html><head><title>{Title}</title></head>
<body bgcolor="white">
<h1>{Title}</h1>
<hr>
<form action="{self}" method="get">
<!-- IF SHOW_FORM -->
<input type="checkbox" name="one"
<!-- IF ONE -->checked<!-- ENDIF ONE -->>One<br>
<input type="checkbox" name="two"
<!-- IF TWO -->checked<!-- ENDIF TWO -->>Two<br>
<input type="checkbox" name="three"
<!-- IF THREE -->checked<!-- ENDIF THREE -->>Three<br>
<input type="submit" name="action" value="Action">
<input type="submit" name="hide" value="Hide Form">
<input type="reset" value="Default">
<!-- ELSE SHOW_FORM -->
<input type="hidden" name="one" value="{ONE}">
<input type="hidden" name="two" value="{TWO}">
<input type="hidden" name="three" value="{THREE}">
<input type="submit" name="show" value="Show Form">
<!-- ENDIF SHOW_FORM -->
</form>
<!-- IF ONE -->
<ul>
<li>One: {ONE}
<li>Another One text
<!-- IF TWO -->
<ul>
<li>Two: {TWO}
<li>Another Two text
<!-- IF THREE -->
<ul>
<li>Three: {THREE}
<li>Another Three text
</ul>
<!-- ENDIF THREE -->
</ul>
<!-- ENDIF TWO -->
</ul>
<!-- ENDIF ONE -->
