Yep! this is exactly what templates are not supposed to do - execute code.

IMHO a cleaner way would be have in template

<a href="{test_url}">foo</a>

Then in your code

$test_url = $sess->url(test.php).$sess->padd_query(array("again"=>"yes"))

set_var("test_url", $test_url);

Need not worry about grabbing things after '?' etc etc.

Also it would be cool if we can have some predefined template variables 
like {sessID}, {selfURL} which will do - well the obvious

Not too much of a problem to implement either ... ....

Just my 2p

Cheers

Hi Richard,

Why don't I? (Sorry, I just start working with the PHPLIB.)

Yes, I thought about something like that, but then I thought there
might be a better way to handle it. ;-)

Thanks, I'll take a look at that.

Hi Guenther,

You don't want to be executing your templates!!

There are two choices here. The way I'd normally do it is to set up my
template like:
<a href="test.php{sess_url_suffix}">foo</a>

Then generate a sess_url, grab the bit from the '?' to the end into
$sess_url_suffix and do:
set_var("sess_url_suffix", $sess_url_suffix)

Obviously a pretty nasty hack to work around a missing template.inc 
feature.


The nicer way was posted by Lukasz Kowalczyk to the old phplib mailing
list back in May 2000 and involves a patch to template.inc so that it
knows about session URLs. 

Note that I've never tried this patch, and it should be implemented by
subclassing Template and overriding the existing finish function.

A snippet of the patch is below. Please excuse the long lines.

 ...Richard.



    * str: string to finish.
    */
   function finish($str) {
    global $sess;
    /* First substitute all URLs which contain question marks (in this case session id
     * is appended after an ampersand (&). With the next pass substitute URLs not containing
     * question marks - this time use `?' as a separator.
     */
    if (isset($sess) && $sess->mode == "get") {
        $str = preg_replace('/<[aA]([^>]+)[hH][rR][eE][fF]="(([^"?]+)\?([^"?]*))"/', '<a\1href="\2&amp;'.$sess->cookiename.'='.$sess->id.'"', $str);
        $str = preg_replace('/<[aA]([^>]+)[hH][rR][eE][fF]="([^"?]+)"/', '<a\1href="\2?'.$sess->cookiename.'='.$sess->id.'"', $str);
        $str = preg_replace('/(<[fF][oO][rR][mM][^>]*>)/', '\1<input type="hidden" name="'.$sess->cookiename.'" value="'.$sess->id.'">', $str);

[Phplib-users] url() in templates

[Guenther T. <th...@eq...>]

Hi,

yet another newbie question. ;-)
I'm working with templates and session. Now I want to replace the
regular links (e.g. <a href="test.php">foo</a>) in my
index.tpl.html-teplate file by something like this:
<a href=" $sess->url('test.php') ">foo</a>
But I'm not able to figure out how to get php to parse the php-part in
the file. Renaming the index.tpl.html to index.tpl.php had no effect.
Anybody any hints?

tia.

Yes, they're read in and have the content substituted on the fly.

Never heard of it. Note that if you've got a busy server (and if your
server isn't busy, why worry about performance ;) and the server has
enough RAM, the template files will all be in cache anyway. In any
event, the cost of reading in the template file is way lower than the
cost of generating the dynamic content and performing the substitution.

If you're using templates and databases to generate pages that are not
unique *every* time (like, say a news releases page that pulls articles
out of a database and is updated only every hour or so) then you can
cache the built pages on disk and not even bother regenerating the
dynamic content each time.

You'd still need to pull a timestamp of the last inserted record out of
the database but if there's no change, you can just blat out the last
version of the page from cache.

There was a patches that did something like this with template.inc
posted by Tom Anderson to the NetUSE mailing list a long time ago.
Sort of a roll-your-own Zend cache :)

True.  In my situation the db connection would already be there, so I guess
the whole template processing would be negligible.  So how do you do it?  Are
your templates parsed dynamically?

I will see what I can come up with.  I doubt I'll be getting to this anytime
soon, but you never know what's going to happen since requirements change.

Btw, maybe one way to speed things up would be to read the templates into
memory at server startup, but I'm not sure if this is possible in PHP?  I
know it can be done with mod_perl, but that's totally different.

Template's real strength is in simplifying the handling of dynamic
pages. it allows you to write PHP code that contains no HTML -- it's
all in the template files.

Of course with *really* complex pages it can be a lot of work to get
*all* HTML out of the code, and you'll have to decide when to stop
based on a cost/benefit analysis.

The best thing though is that when the boss decides to redesign the
site all you have to do is re-jig your template files. In theory!

I think you'll find the overhead from templates is a lot lower than the
overhead from other aspects of your dynamic pages. For example, a call
to preg_replace is much cheaper than the cost of bringing up a database
connection.

Only way to tell for sure is to try it and see :)

If you do run some performance figures, be sure to post them back to
the list... that always generates a lot of interest.

Yup, that's how I'd do it (typos excluded :). Is that not what you
are looking for?

Oh, and I think you're missing a "true" to your parse call... you
probably want to append these records.

RE: [Phplib-users] dumping vars in a block

[Daniel B. <bo...@io...>]

sorry, may bad
forgot to say, that I only wanna set address2 if it exists

if ($q->f("address1")) {
	$tpl->set_var("address2",$q->f("address1")."<br>";
} eles {
	$tpl->set_var("address1","");
}

if ($q->f("address2")) {
	$tpl->set_var("address2",$q->f("address2")."<br>";
} eles {
	$tpl->set_var("address2","");
}

if ($q->f("address2")) {
	$tpl->set_var("city",$q->f("city")."<br>";
} eles {
	$tpl->set_var("city","");
}

then in the html I have=20
{address1}{address2}{city}{state}{zip}
so I don't get a blank line if address2 does not exist.

Won't the line:
$tpl->set_var("address2",$q->f("address2");
clear the var if there's no value?

[Phplib-users] dumping vars in a block

[Daniel B. <bo...@io...>]

I am using the template class.
I have a repeating block in a while loop with about 25 vars in it.

something like this

while($q->next_record()) {
	$tpl->set_var("firstname",$q->f("firstname");
              ...
	$tpl->set_var("address2",$q->f("address2");
             ...
	$tpl->parse("addresses",'addressblock")
}


not every record is going to have address2
how do I clear out all the vars in this block before setting them all
for the current record and parsing again.

thanks
