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

I'm trying to use the <if $CONDITION then></if> conditionals to display certain links in the header/navigation to only members of certain usergroups.

All of my <if></if> and PHP code is being output to the browser - it's obvious the mod is not functional and is not parsing the code...

[RateU]

Did you try this condition:

Code:

<if $mybb->user['usergroup'] == x then> Your link here </if>

---

Change the x with user group id.

Change the x with user group id.

Yes.  This is not a syntax error.

If I put that in a template with 'x' replace with '1' (Guests) and view my forum logged in as Admin (shouldn't display) it still displays. If you were to view source you will see this in the source:

Code:

<if Array['usergroup'] == 1 then> Your link here </if>

The plugin seems to be installed wrong (maybe because it doesn't include any instructions) or not functional - for whatever reason.

EDIT: I've posted a detailed update of this issue here: http://community.mybboard.net/thread-318...http://community.mybboard.net/thread-31860-post-492659.html

Did you try it in a fresh MyBB installation?

Instructions are here - I'm just too lazy to redocument everything for all these plugins.
But from your descriptions, it does sound like the plugin isn't activated at all, although you seem to be doing the right things.  As suggested, try it on a clean install of MyBB 1.4.11-13 (haven't tested it on .13, though it shouldn't be different there) and see if it works.

[RateU]

I've tested in MyBB 1.4.13. It works perfectly.

I am trying to build a set up for a book review forum and I thought it would be cute if the replies to the book review post had the users avatar as an icon for "who posted".

I have this working fine for posts by users, but I have forum settings set so that guests can post. Of course, guests have no avatar, so I wanted to use the php/templates Conditionals plug in to put an IF statement around the avatar image - something along the lines of

<if {post is by a guest} then <show this image> else {show posters avatar}.

This is the HTML I am using to get the small avatar to show (miniav is a .css class I made for the borders/styling on the avatar). This is working fine. Its the swap for the guest image I am struggling with. I have a default avatar set up on my forum, that is the image I want to link to.

Code:

1 2 3 4 5 6 7 8

<td class="tcat"> <div class="float_left smalltext"> <img src="{$post['avatar']}" class="miniav" "width="35" height="35" /><strong> <span class="smalltext">&nbsp;{$post['profilelink']}</span></strong> - {$post['postdate']}, {$post['posttime']}<span id="edited_by_{$post['pid']}"></span> </div> {$post['posturl']} </td>

Here is a link to an example:  http://www.leefish.nl/mybb/showthread.php?tid=33 Once this is all polished up I hope to post it here in the XThreads examples forum - so I want it to be REALLY nice

I don't know which variable to call. Can anyone help?

[RateU]

Try something like this:

Code:

<if $post['avatar'] then> <img src="{$post['avatar']}" class="miniav" "width="35" height="35" /> <else> <img src="image_path_for_guest_avatar" alt="" title="" /> </if>

Thank you RateU. Indeed, I was thinking along the lines of <ïf poster was guest> but I see you cut the middle man out and went straight for <if the image defined as an avatar is there then blah blah>. I see.

[RateU]

I merged the thread

Yes, the code not only for guest, but for member who doesn't have avatar too. You can use $post['uid'] if you really want it for guest only.
