Embed PHP in Templates

This hack lets you embed PHP code in templates. Simply add your code between a <? (not a <?php) and ?> tag and it will be eval'ed. All variables will be referenced in the global scope.

If you're using my Usergroup Tags in Templates hack then you're going to have an extraordinarily difficult time installing this hack. However the clever hacker can tell what has changed in this version.

You can somewhat use this to do conditionals in templates. Theoretically, this will work:

Code:

template...

<? $myvar = ($condition ? $truevalue : $falsevalue); ?>$myvar

...more template...

Just make sure that the variable to the left of the = and the variable right after the ?> match. Note that the entire <? and ?> tag itself will be stripped from the final template.

This hack also enhances the comments delimiting templates (if that option is turned on) to include the character count and PHP block count of the specified template.

Wow, this leaves all the template conditional hacks in the dust. I might even install this one!

Great job, filburt!

Very nice filby! Is this efficient?

I dont think effecient is the way to put it, its only as effecient as the code u put between the tags....if u just put <? ?> or <? // ?> its not gonna slow anything down a bit...

What are the limitations on the use of PHP ?

N9ne	05-11-2003 01:39 PM

Mist, as far as I know, I don't think there are any, as the example that Filburt gives with the if condition statement looks like proper PHP so by the looks of that, a lot can be done.

Thank you very much... i try to use this script

05-11-2003 03:39 PM

N9ne - its called a ternary operator i believe ;)

I'm very interested to see how this develops as IMO i think we'll see a lot of PHP errors popping up now on vBulletin.org due to poor PHP coding in the templates :)

Theoretically it is only limited by the speed of the preg functions.

Pseudo-code of what it does:

1. Find every occurance of <? and ?> (and what's inbetween them)
2. For each occurance, make every variable within in the global scope, and then eval what's in the occurance
3. Remove the original occurances from the template.

And so, no need to modify PHP files to create new hack (even if I'll continue to modify the php files for my new hack, but this can be usefull for some modifications ;) )

[high]* grog6 cliks install too :)

Thx for it Filburt

nice hack, I fixed it slightly though to suit my needs:

PHP Code:


		
			
        if (substr_count($template,'?'.'>')>=1 or substr_count($template,'php?'.'>')>=1 or substr_count($template,'</php>')>=1) {

            while (preg_match("/(\<\?php|\<\?|\<php\>)(\r\n)*(.*)(\r\n)*(php\?"."\>|\?"."\>|\<\/php\>)/siU", $template, $matches)) {

                if ($parse_phpcode) {

                    preg_match_all("/\\$[a-zA-Z_\x7f-\xff][a-zA-Z0-9_\x7f-\xff]*/", $matches[3], $varnames);

                    $varnames = implode(", ", $varnames[0]);

                    if (!empty($varnames)) {

                        @eval("global $varnames;");

                    }

                    $eval_result = @eval(stripslashes($matches[3]));

                } else $eval_result = "";

                $template = str_replace($matches[0], $eval_result, $template);

            }

        }

You can now use:
<? ?>
<?php php?>
<php></php>

and any combinations of them, such as:
<?php ?>

and so on.

Also now if you use return(stuff here); in the php script, it returns the data straight to the template itself. Like:
<?
$stuff = "stuff";
return $stuff;
?>

would return the $stuff varible right into the template for you.

Odd... the following code doesn't seem to work:

Code:

<?

$default = "home";

if($page == ""){$page = $default;}elseif(isset($page)){$page = $page;}

?>

<?

include ("$page.html");

?>

What have I done wrong?

filburt1

05-13-2003 01:18 PM

For one thing, break it up with some whitespace so it's readable...

Try this:

Code:

...

<?

if (empty($page)) $page = "default";

include("$page.html");

?>

Also include and require may cause unpredictable results; you'll probably need to play with the output buffering settings and that'll destroy gzip.

But quite usefull, if you want to have templates be more useful

It doesn't work. :(

PHP code goes through (somewhat) unparsed. I can say:
[code]<? if ($post[usergroupid] != 5) {
$var = "..."
}
?>

And it would show up as...

Code:

<? if (6 != 5) {

$var = "..."

}

With the 6 being the correct usergroup id. :ermm:

Are you sure you installed it correctly? In what template are you using that code?

Yes, I triple checked it and it doesn't work. :( That was in postbit, but I've tried it in the header as well.

What do you mean by point 2?
No php working for me. The require function just hangs on the IE browser. Can you fix that, fil?

The template, not the PHP in gettemplate...

You're also not using my original hack, so I support it even less...

bryanzera

05-21-2003 11:18 PM

I'm not getting this to work either. Such is my code:

Quote:

<a href='http://www.pollstar.com/member/index.cgi?Premium=1&From=http://forums.pollstar.com<? return getenv('REQUEST_URI') ?>'>Log in to Pollstar Premium now!</a>

what I get is this in my link field:

Quote:

http://www.pollstar.com/member/index.cgi?Premium=1&From=http://forums.pollstar.com<? return getenv(

Is the getenv out of this hack's scope?

filburt1

05-21-2003 11:20 PM

This hack doesn't work this way. All it does is blindly execute the code in the tags and a return statement will confuse the hell out of it.

Instead use:

Code:

...<? $something = getenv("REQUEST_URI"); ?>$something...

bryanzera

05-21-2003 11:39 PM

Still doesn't seem to work right. this code:

Quote:

<a href='http://www.pollstar.com/member/index.cgi?Premium=1&From=http://forums.pollstar.com <? $something = getenv("REQUEST_URI"); ?>$something'>Log in to Pollstar Premium now!</a>

gives this url:

gmarik

05-22-2003 04:01 AM

Filburt. Doent know why,
but your origianl hack does not works in ant way.
Our ou should write a manual, how to use it.

I need to write freely php code in every template, can I do it?

05-30-2003 03:36 PM

anyawy so that i can include files
cause when do it just displays on top no matter where i put the code

gmarik

05-30-2003 06:53 PM

GameZilla,
All you need is all I need.
I don't care how - it must work as an ordinary php file!!
