Template Conditionals

This is essentially a more restrictive version of my PHP in Templates plugin.  The restrictions aim to make this a "safe" plugin to use, that is, doesn't allow arbitrary PHP execution, but still gives the benefits of template conditionals.

You may notice that this still uses the "phptpl" name, and thus, is incompatible with the PHP in Templates plugin.  Both plugins are very similar though.  The differences between this and the other plugin are:

• Admins cannot enter PHP code using <?php ?> tags
• Conditionals in <if> and <elseif> tags are checked to ensure that they are "safe" (see below)
• file_get_contents function has been removed from the allowable <func ...>...</func> shortcuts
• There's a new <?=...?> tag to print out the result of a "safe" PHP expression; although this is a tag, only PHP expressions may exist inside (do not terminate expressions with a semicolon), so you cannot nest other tags inside this
  Example (prints 123654321):
  HTML Code

  123<?=substr("987654321", 3)?>

  ---

• There's also a new <setvar name>...</setvar> tag which can set variables; for safety reasons, these are actually stored in a $tplvars array.  Examples:
  (just prints some text)
  
  HTML Code

  <setvar uselesstext>"some text"</setvar> {$tplvars['uselesstext']}

  ---

  (prints out the username of the user with UID of 2)
  

  HTML Code

  <setvar user2>get_user(2)</setvar> <func htmlspecialchars_uni>{$tplvars['user2']['username']}</func>

  ---

v1.0-1.3 of this plugin is based off v1.7 of PHP in Templates.
As of v1.8, PHP 5.3 or later is required.
This plugin can be used with the Admin Security plugin.

"Safe expressions"
This plugin implements "safe expression" checking; essentially, this does impose a bit of a performance hit, but, on the other hand, tries to ensure no "bad PHP" gets executed.
For more information on what I consider to be a "safe expression", see my blog post here.
For the purposes of this plugin, all valid PHP expressions are allowed, as long as they don't infringe on any of the following conditions:

• no assignment/modification operators (=, +=, |=, ++ etc) allowed
• no statements such as include, exit, eval etc are allowed
• no special constants such as PHP_OS, PHP_LIBDIR etc are allowed
• backtick (`) operator not allowed
• heredoc type strings not allowed (takes too much effort to handle) - use double quoted strings instead
• double quoted strings may not contain the "{" character (takes too much effort to handle) - use string concatenation instead
• array and object typecasting not allowed
• no variable functions or method calls allowed
• single line comments (//, #) not allowed
• only some functions are allowed - see inc/plugins/phptpl_allowed_funcs.txt for a list of allowed functions

No, database queries are not considered a "safe" operation, so can only be done via PHP in Templates.

Wouldn't that just show the code or text to a certain person on the forums? I think he wants to show it to a certain group.

Also, I just tried this on my forum and it showed it to me while I was logged in and logged out.

I was wondering how I would show a "verified" badge on that groups member profiles. Can you do that with this plugin?

Guest "doesn't have" an uid.

Not quite sure how you applied it. I've just tested it and works for me.

You can use usergroup

Would it be like:

Code:

<if !$mybb->usergroup['gid'] then>blah</if>

Sorry, I'm not very good with php yet. If that's not right could you give me an example?

[RateU]

In member_profile template, right?

You need to use $memprofile['usergroup']

For example:

Code:

<if $memprofile['usergroup'] == 4 then>blah</if>

I can use that multiple times right and what about if I want to use it on say the index or another page? By multiple times I mean that I can show multiple things on a single profile if they are in multiple groups.

Some areas have its own data array (for example, the $memprofile applied in user profile for the profile owner). You use $mybb->user for the viewer.
