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:

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.

PHP Code:

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;
    
    $templatesetid = intval($templatesetid);
    if (isset($templatecache[$templatename]))
    {
        $toreturn = $templatecache[$templatename];
    }
    else
    {
        $template = $DB_site->query_first("SELECT template FROM template
            WHERE title = \"" . addslashes($templatename) . "\"
            AND (templatesetid = -1 OR templatesetid = $templatesetid)
            ORDER BY templatesetid DESC LIMIT 1");
        $toreturn = $template['template'];
        $templatecache[$templatename] = $toreturn;
    }
    
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, $matches)) {
                if ($parsephp) {
                    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);
            }
        }

    if ($parsephp) // is this needed still?
    {
        // regex is mangled to avoid breaking stupid ides
        $count = preg_match_all("/<\?(.*)\?" . ">/siU", $toreturn, $matches);
        foreach ($matches[1] as $match)
        {
            // put vars in the global scope
            preg_match_all("/\\$[a-zA-Z_\x7f-\xff][a-zA-Z0-9_\x7f-\xff]*/",
            $match, $varnames);
            $varnames = implode(", ", $varnames[0]);
            if (!empty($varnames)) eval("global $varnames;");         
            eval($match);
        }
        
        str_replace($matches[0], "", $toreturn);
    }       

    if ($escapecontents)
    {
        $toreturn = addslashes($toreturn);
        $toreturn = str_replace("\'", "'", $toreturn);
    }
    
    if ($gethtmlcomments and $addtemplatename)
    {
        $charcount = strlen($templatecache[$templatename]) .
            " chars originally";
        $phpcount = ($parsephp ? ", $count embedded PHP tags" : "");
        
        return "<!-- begin template \"$templatename\" ($charcount$phpcount) " .
            "-->\n$toreturn\n<!-- END TEMPLATE: $templatename -->";
    }
    return $toreturn;

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!!
