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

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

Got it working, used this and worked a treat! Thanks!

I'm a bit of a novice and I was wondering how to use the conditionals to create more than two different codings?

IE for the moment I can have:
<if id = 1>
First template
</else>
Second template
</if>

But what if I wanted to have eight different templates? How would I go about doing that? I've tried just adding more if conditionals within it but it doesn't work.

Nesting?

Code:

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

<if $forum['fid'] == 1 then> ID 1 <else> <if $forum['fid'] == 2 then> ID 2 <else> <if $forum['fid'] == 3 then> ID 3 <else> something else </if> </if> </if>

---

Or reduce the clutter with elseif's

Code:

1 2 3 4 5 6 7 8 9

<if $forum['fid'] == 1 then> ID 1 <elseif $forum['fid'] == 2 then> ID 2 <elseif $forum['fid'] == 3 then> ID 3 <else> no, I'm not going to put any more IDs </if>

Perfect! Thanks so much

Hello Zinga, really good job. Thanks!
I read that the code to extract data from the database is the follow. How do I set it to extract all rows from db?

Quote:{$attachment['icon']}&nbsp;&nbsp;<a href="attachment.php?aid={$attachment['aid']}" target="_blank">{$attachment['filename']}</a> ({$lang->postbit_attachment_size} {$attachment['filesize']} / {$lang->postbit_attachment_downloads} {$attachment['downloads']}
<?php

   $affected_fids = explode(',', $mybb->settings['newpoints_atcost_forums']);
   if (in_array($fid, $affected_fids)){

   $attach_id = $attachment['aid'];
   $attach_check = $db->query("SELECT * FROM mybb_newpoints_attachments WHERE AID='$attach_id'");
   $rows = $db->num_rows($attach_check);
   if ($rows > 0){
    $attach_cost = $db->fetch_field($attach_check, "cost");
    $attachment_cost_points = "/ <font color='red'>Cost:</font> ".$attach_cost;
}
}
?>
)

Use looping, like while?

I used this code, but it doesn't work. I'm not good in object-oriented programming.

Quote:$query_2 = $db->query("SELECT * FROM voto_voti WHERE id_user = '$userid'");
$number_2 = $db->num_rows($query_2);

$i = 0;

if ($number_2 > 0){          
while ($number_2 > $i){          
$id_domanda = $db->fetch_field($query_2, "id_domanda");
$i++;
}
}
}

If you are really sure that it is rows, not columns in one row only, maybe something like this:

PHP Code:

while ($mydata = $db->fetch_array($query_2)){ // $mydata array here }

MyBB is pretty much all procedural.  The only link with OO is a few classes, which basically just act as fancy functions.

Although your code should work (as far as the loop is concerned), assuming you're using the data somewhere.
