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

Variables are written in PHP code so, unfortunately, there's no general rule other than to look through the code itself.

In the EDITPOST template on a MyBB 1.8.12 board, I'm trying to create a condition where:

IF, the post being edited is the first post in the thread, the subject field can be edited

ELSE, (the post is not the first post,) the subject field cannot be edited

I've been playing around with mixed results, but not having any luck.

#################################################

This BELOW allows all posts in the thread to have the subject field edited. - the logic seems to flow down the IF path...

Code:

1 2 3 4 5 6 7 8 9 10 11 12 13

<if $thread['pid'] = 1 then> <tr> <td class="trow2" style="color:red; background-color: #fbe3e4"><strong>Edit Your Subject ?</strong></td> <td class="trow2" style="background-color: #fbe3e4">{$prefixselect}<input type="text" class="textbox" name="subject" size="60" maxlength="85" value="{$subject}" tabindex="1" /></td> </tr> <else /> <tr> <td class="trow2" style="color:red; background-color: #fbe3e4"><strong>Thread Subject:</strong></td> <td class="trow2" style="background-color: #fbe3e4">{$subject}</td> </tr> </if>

---

This BELOW allows all posts in the thread to have subject field edited. - again, logic seems to follow the IF path...

Code:

1 2 3 4 5 6 7 8 9 10 11 12 13

<if $post['pid'] = 1 then> <tr> <td class="trow2" style="color:red; background-color: #fbe3e4"><strong>Edit Your Subject ?</strong></td> <td class="trow2" style="background-color: #fbe3e4">{$prefixselect}<input type="text" class="textbox" name="subject" size="60" maxlength="85" value="{$subject}" tabindex="1" /></td> </tr> <else /> <tr> <td class="trow2" style="color:red; background-color: #fbe3e4"><strong>Thread Subject:</strong></td> <td class="trow2" style="background-color: #fbe3e4">{$subject}</td> </tr> </if>

---

This BELOW does not allow editing of the first or any subsequent posts. - the logic seems to follow the ELSE path...

Code:

1 2 3 4 5 6 7 8 9 10 11 12 13

<if $post['pid1'] then> <tr> <td class="trow2" style="color:red; background-color: #fbe3e4"><strong>Edit Your Subject ?</strong></td> <td class="trow2" style="background-color: #fbe3e4">{$prefixselect}<input type="text" class="textbox" name="subject" size="60" maxlength="85" value="{$subject}" tabindex="1" /></td> </tr> <else /> <tr> <td class="trow2" style="color:red; background-color: #fbe3e4"><strong>Thread Subject:</strong></td> <td class="trow2" style="background-color: #fbe3e4">{$subject}</td> </tr> </if>

---

Lastly, same result here where the logic appears to follow the ELSE path...

Code:

1 2 3 4 5 6 7 8 9 10 11 12 13

<if $thread['pid1'] then> <tr> <td class="trow2" style="color:red; background-color: #fbe3e4"><strong>Edit Your Subject ?</strong></td> <td class="trow2" style="background-color: #fbe3e4">{$prefixselect}<input type="text" class="textbox" name="subject" size="60" maxlength="85" value="{$subject}" tabindex="1" /></td> </tr> <else /> <tr> <td class="trow2" style="color:red; background-color: #fbe3e4"><strong>Thread Subject:</strong></td> <td class="trow2" style="background-color: #fbe3e4">{$subject}</td> </tr> </if>

---

Clearly, your plugin is functional as I can observe the logic flowing either down the IF or down the ELSE paths.

I'm just misapplying it.

Any help?

^ I updated my previous post so it's less vague. If anybody wants to take a second look, please do.

Thanks

Hi

If i wanted to run a script in headerinclude template, but wanted to exclude it from executing on say showthread.php, what would be the best / correct php syntax to use ?

<if !showthread.php then>
<script src="{$mybb->asset_url}/jscripts/somescript.js"></script>
</if>

Hi, I think it's:

Code:

<if THIS_SCRIPT != 'showthread.php' then><script src="{$mybb->asset_url}/jscripts/somescript.js"></script></if>

I'm using "PHP and Template Conditionals" plugin but there is always an error where I add <if> conditional, for example:

Parse error: syntax error, unexpected '' (T_ENCAPSED_AND_WHITESPACE), expecting identifier (T_STRING) or variable (T_VARIABLE) or number (T_NUM_STRING) in /srv/users/serverpilot/apps/(appname)/public/forum/global.php(527) : eval()'d code on line 2

I'm using also PHP 7.0, maybe it isn't compatible with PHP 7.0?

EDIT: nothing, sorry, I have uploaded from 2.0 to 2.1 and now it works without problems, I didn't see the update sorry

Unfortunately this plugin won't really enforce that.  At most, you could hide the inputs, but it won't actually stop someone editing a subject.  You'd need something more complex, like a plugin, for that.
If you don't actually care about post subjects though, you could just hide them in posts instead (or display the thread subject there instead).
