Embed PHP in Templates

[filburt1]

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:


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.

I'm definately going to use this when I get back :) Thanks for the hack filburt!

[Link14716]

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

Great job, filburt!

[N9ne]

Very nice filby! Is this efficient?

[Trigunflame]

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...

[Dean C]

What are the limitations on the use of PHP ?

[N9ne]

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.

[Danielo]

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

[Dean C]

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 :)

Very nice filby! Is this efficient?

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

[mx3]

awesome! will install! i've been wanting this for awhile now!

[all-the-vb]

nice work


:) All-the-vb click install

[filburt1]

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.

[grog6]

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 ;) )

* grog6 cliks install too :)
Thx for it Filburt

[Chris M]

Very nice filby;):)

[mossyuk]

Very nice, thanks! :bunny: :banana:

[Slynderdale]

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

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.

[kaotic]

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

<?
$default = "home";
if($page == ""){$page = $default;}elseif(isset($page)){$page = $page;}
?>
<?
include ("$page.html");
?>

What have I done wrong?

[filburt1]

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

Try this:

...
<?
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.

[zajako]

>.< It made me go cross eyed :]
But quite usefull, if you want to have templates be more useful

[cirisme]

It doesn't work. :(

PHP code goes through (somewhat) unparsed. I can say:
<? 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:

[Wildthinks]

I'm to stupid...

That what i get after insert the code. .... in functions...

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

[Katana Myronson]

FILBURT I LOVE YOU!!!

*cliks install*

(Yes i know i spelt click wrong i spelt it that way on purpose ;))

[mossyuk]

Im getting the page full of Parse error's as well. Running 2.2.7 if thats making any differance?

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?

[filburt1]

What is the exact code you're using?

[gmarik]

function gettemplate($templatename, $escapecontents = true,
$gethtmlcomments = true, $parsephp = true)
{
// gets a template from the db or from the local cache
global $templatecache, $DB_site, $templatesetid, $addtemplatename;

[filburt1]

The template, not the PHP in gettemplate...

[filburt1]

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

[bryanzera]

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

<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:

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]

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:

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

[bryanzera]

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

<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:

http://www.pollstar.com/member/index.cgi?Premium=1&From=http://forums.pollstar.com <? = getenv("REQUEST_URI"); ?>

[filburt1]

Make sure you're using my original hack and not the one you quoted.

[gmarik]

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?

[GameZilla]

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

[gmarik]

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

[DraX]

The problem with file inclusion is that this is completely contrary to the way in which vBulletin handles it's output buffering.

It doesn't generate line after line, it generates the entire page, and then sends that to the browser once it's compiled it.

For includes to work properly, anything (echos, output, etc.) would have to be stored as variables within the include, which are then echoed by the template itself.

[gmarik]

DraX - and what is the solution? Any code ideas?

[Rob - PROMISE]

Hello, sorry if this has been answered, I have read through and can't find anyhting relating to my problem.

I have installed the hack, I then dropped '<? ?>' (without the quotes) into the header of one of our templates. When I view the page it's not parsing the php, I can see the php tags in the source.

I then tried dropping an include in the same place but I then just get a blank page. I read that there are issues with using includes in the templates and I can live without using them although it would be very useful if I could.

Can you shead any light, let me know if you need any more details.

Thanks for your help people :)

[gmarik]

You're not the only one.
I can't get php working in my 2.3 templates too.
Any solutions in v3? Anybody, Fil, xenon?!

[Veg]

Can you retrive information from the database with this hack?

[gmarik]

Theoreticaly it operates template DB. Theoreticaly.

[Importhookup]

Great hack!

I am so glad that I found this hack, but the problem is that I'm having trouble installing it. I did exactly what is written in the file, the simple replacement of the code but this is what I get on the top of myVBindex.php.

Warning: Failed opening 'randomride.php' for inclusion (include_path='.:/usr/local/lib/php') in /home/importhookup/public_html/forums/admin/functions.php(1095) : eval()'d code on line 1

Parse error: parse error, unexpected T_INCLUDE in /home/importhookup/public_html/forums/admin/functions.php(1095) : eval()'d code on line 1

Can someone help me with this? Thanks!

[ChurchMedia]

If I use include statements, it works but always puts the include file at the top of the page. Any way around this?

Thanks for the cool hack!

[Link14716]

Not working... at least not in the postbit.

Code used:
<?
if (!empty($post[field7])) {
$postfollower = "<br><br>";
$postfollower = $postfollower."".bbcodeparse2($post[field7],0,1,1,1);
}
if (!empty($post[field5])) {
$posttextcolor = "color='".$post[field5]."'";
}
if (!empty($post[field6])) {
$postfontface = "face='".$post[field6]."'";
}
if (!empty($postfontface) || !empty($posttextcolor)) {
?>
<font $postfontface $posttextcolor>
<? } ?>
$post[message]
<? if (!empty($postfontface) || !empty($posttextcolor)) { ?>
</font>
<? } ?>
$postfollower

View Source gives me this, of course on the page the code didn't work:
<?
if (!empty(Official Code +++++)) {
= "<br><br>";
= ."".bbcodeparse2(Official Code +++++,0,1,1,1);
}
if (!empty(blue)) {
= "color='".blue."'";
}
if (!empty(WingDings)) {
= "face='".WingDings."'";
}
if (!empty() || !empty()) {
?>
<font >
<? } ?>
I've nailed the store, arcade, increased the arcade's number of games to 41, installed quick reply, and installed zajako's RPG hack. I'm done for tonight.
<? if (!empty() || !empty()) { ?>
</font>
<? } ?>

[gmarik]

Is it working in v3?

[Tae-Hwan]

filburt, in your opinion does this render logician's conditionals hack obsolete? i'm fluent in php. i liked logician's conditionals a lot except that it was kinda slow..

[drives fast]

I have tried many combinations and haven't figured out this one yet

if someone would be so kind

this is what I had figured out in the vb3 conditionals:
<if condition="$post[usergroupid]==11"><font color="#ffcc00" face="verdana, arial, helvetica" size="1"><b>Site Supporter</b></font> <img src="/forum/eimages/supporter.gif" width="11" height="11" border="0" /></if>

how can that be modified to work within the <? ?> in the earlier vbulletin version that I have installed this hack in?

I have tried several things but only get parse errors displayed above the header

stuff like:
<?
if (condition = $post[usergroupid]==11) {
$var = "<font color=\"#ffcc00\" face=\"verdana, arial, helvetica\" size=\"1\"><b>Site Supporter</b></font> <img src=\"/forum/eimages/supporter.gif\" width=\"11\" height=\"11\" border=\"0\" />"
}
?>
and:
<?
if ($post[usergroupid] != 11) {
$var = "<smallfontcolor='#ffcc00'><b>Site Supporter</b></smallfont> <img src='/forum/eimages/supporter.gif' width='11' height='11' border='0' />"
}
?>

I know it is just because I don't know the language to use

thanks a bunch for any help

[drives fast]

once again...I couldn't get bit by a dog even with a steak hanging around my neck

[Tae-Hwan]

once again...I couldn't get bit by a dog even with a steak hanging around my neck

hehe, i never heard that one before...

well, i don't have any experience in vbulletin 3, but if i'm understanding the code correctly, it should look something like this in php:


<?
if ($post[usergroupid]==11) {
echo "<font color=\"#ffcc00\" face=\"verdana, arial, helvetica\" size=\"1\"><b>Site Supporter</b></font><img src=\"/forum/eimages/supporter.gif\" width=\"11\" height=\"11\" border=\"0\">";
}
?>

[drives fast]

thank you...I will give that a try.

it looks like it will work though....I forgot about the "echo"

[gmarik]

We all forget some times about the quotes or the echo ...

[stephenv]

I read through some of the other messages AFTER modifying/fixing the original script, I would have added the <?php ?> <php> </php> stuff but I can't be arsed. On a deadline for other stuff.

That said, attached is an updated version that uses output buffering (in case you want to echo text) and also fixes the str_replace that didn't do squat :)



Mail me at stephen AT natnet DOT com if you want to say thanks or have questions, today was my first day on the board and I probably won't be back (fixed for a client who wanted to use phpAdsNew).

Very usefull! I hope this will possible in vb3 soon. :)

With these modifications, the hack works like a charm for what I needed it to do, which was to pull a php file into the header template via include(). the original hack would pull the file into the page but only at the top of the page and not where it was supposed to display.

For everyone else that had a similar problem, try this version. My thanks to both authors that worked on this.
