PHP in Templates / Complex Templates

This is a relatively small plugin, but seems that a number of people wanted such a thing, so... here it is.

This plugin will allow you to use:

• PHP in templates, using <?php ... ?> tags
• Shortcut template conditionals, using <if ... then>...<elseif ... then>...<else>...</if>
• Some shortcut string functions (see below), eg <func htmlspecialchars>...</func>
• Call another template, using <template ...>, eg <template header>
  

For those that do not wish to allow arbitrary PHP code execution that this plugin offers, take a look at the Template Conditionals plugin.

Here's an example of some of the functions that this can be used for - for example, you may use this code in your postbit:

HTML Code

1 2 3 4 5 6 7 8 9

{$post['user_details']} <if $post['fid5'] then> Your game tag is <func htmlspecialchars_uni>{$post['fid5']}</func> <elseif $post['fid6'] and $mybb->user['cancp'] then> This user's lucky number is <func intval>{$post['fid6']}</func> <else />Some other profile field: {$post['fid7']}</if> <?php echo "Hi from PHP"; ?>

---

Some notes:

• PHP tags must be closed with ?>
• PHP runs slower than conditionals, so unless you need to use PHP, I recommend the conditionals
• PHP inside the <?php ... ?> tags must be well formed, ie the following will not work:
  
  PHP Code:

  <?php if(true) { ?> some stuff <?php } ?>

  ---

  I'm thinking about whether to add support for the above, but there are performance reasons for me choosing not to.

• The template insertion function is really basic - it performs no caching, so you should not call a lot of templates this way (there really isn't any nice way to get around this) however should be fine for small things.  Also, as it is basic, ensure that you don't stuff it up with recursive calls, that is, it's possible to try to get a template to call itself, but that will obviously cause MyBB to stuff up
• As of v1.5, I've included the ability to perform additional cache checks, and enabled this option by default.  If you wish to disable this feature, it can be done by modifying a define in the .php file, but this is not necessary for most people (see post below this one for more info).
• As of v2.1, PHP 5.3 or later is required
  

The functions available, with the shortcut, are:
htmlspecialchars, htmlspecialchars_uni, intval, file_get_contents, floatval, urlencode, rawurlencode, addslashes, stripslashes, trim, crc32, ltrim, rtrim, chop, md5, nl2br, strrev, strtoupper, strtolower, my_strtoupper, my_strtolower, alt_trow, get_friendly_size, filesize, strlen, my_strlen, my_wordwrap, random_str, unicode_chr, bin2hex, str_rot13, str_shuffle, strip_tags, ucfirst, ucwords, basename, dirname, unhtmlentities

Probably an issue with one or more of the following templates:
global_pm_alert, headerinclude, gobutton, htmldoctype, header

Try reverting them (save a backup beforehand) to see if any of them are causing the problem.

Thanks the issue has at headerinclude .
Thank you so much for the help.

Add one more heartfelt "thank you".  I needed to add some PHP somewhere (for a link exchange) and this saved me from having to learn how the core handles templates.  (I'll figure it out eventually, but I wanted to get a few things actually done.)

And I'm sure that reading your code is going to help me learn how MyBB works.  (Until 2.0 - then we all start from zero, I guess.)

Thanks again.

Hey there, was just wanting to make sure this is accomplishable before I download this mod.

Basically I'm looking to create the effect like the following two sites:

site one and site two

Do you see how their first categories and forums look different to later ones? IE: On site two the first category has horizontally stacked forums whilst the second category stacks three side by side and includes images? Essentially that's what I'm trying to achieve.

I think I'd use some sort of conditional in the templates and use forum IDS:

For example:

<if category=1> Template here </else> Other template here </if>

I hope I've explained myself! Do I make any sense?

Try it and post back.

Well I don't know what to try, that's why I was asking. Does anybody know how I'd go about it?

Nope, definitely not. But thanks for the suggestion.

You can try to check by using $forum['fid']. Something like this:

Code:

<if $forum['fid'] == x then> Codes for forum id = x here <else> Codes for other forum ids here </if>

If it's a complex modification, personally, I prefer using XThreads for that.

Okay I will give that a go thank you!

I've downloaded it and tried to unzip the package but it isn't working! Is there a different file format or a recommended unzipper (for mac).
