Hi,

I have created some new Smarty plugins, and two patches to other smarty
plugins. There are too many lines to post it here, that is why I made
it available at
  http://www.klaban.torun.pl/patches/smarty/

There are available the following plugins:

1. Assign smart variables from PHP eval'ed values:
     function.assign_php.php
     function.eval_php.php

   Example of usage:

{assign_php var="colorarr"
    value="array('#FFFFFF','#AAAAAA','#BBBBBB','#C0C0C0')"}
{eval_php assign="coloridx" var="rand(0,3)"}
<font color="{$colorarr.$coloridx}">Test</font>

2. Localization (changed plugins):
     modifier.date_format.php  (not new plugin, only patched)
     function.html_select_date.php (new 'locale_time' parameter)

{$smarty.now|date_format:"%e %B %Y %T":"":"PL"} // date in Polish
{$smarty.now|date_format:"%e %B %Y %T":"":"DE"} // date in German
                                          ^^^^ - additional locale argument

Select date in Polish with Polish field order:
  {html_select_date locale_time="pl" field_order="DMY"}
Select date in English (if web server locale is not 'en'):
  {html_select_date locale_time="en"}

3. New plugins - presenting arrays as a set of INPUT HTML elements
   either radio boxes or checkbox-es (similar to html_options):

     function.html_radio.php
     function.html_checkbox.php

Example usage (similar to html_options; new 'name' parameter):
   
   {html_radio    name="test-radio[]" values=$vals
                  selected=$selected output=$output}

   {html_checkbox name="test-checkbox[]" values=$vals
                  selected=$selected output=$output}

gives e.g.:

<input type="radio" name="test-radio[]" value="1" /> A<br>
<input type="radio" name="test-radio[]" value="2" checked="checked" /> B<br>
<input type="radio" name="test-radio[]" value="3" checked="checked" /> C<br>

<input type="checkbox" name="test-checkbox[]" value="1" /> A<br>
<input type="checkbox" name="test-checkbox[]" value="2" checked="checked" /> B<br>
<input type="checkbox" name="test-checkbox[]" value="3" checked="checked" /> C<br>

You can also add all_extra parameter. E.g. all_extra="onClick='...'" 

4. APPENDING VALUES (function.append.php and function.strcat.php)

Documentation is not clear in the Chapter 13, about what 'append'
method can do. I thought that it is a mthod for concatenation,
like a dot in PHP. What I realize is that append makes an ARRAY
and appends new value as a last item of the array.

BTW in append_by_ref in Chapter 13 there is a spell mistake -
Technical note talks about assign_by_append() while it should be
append_by_ref(), and example is 'void assign()' while it should be
append_by_ref().

Last two new plugins:
   function.append.php  - calls $smarty->append() on a given variable
   function.strcat.phps - adds new value to the end of the string variable

Example usage:

{assign var="name" value="Smarty"}
{strcat var="name" value=" Template"}
{$name}

gives output: 'Smarty Template'
