SPECIAL FUNCTIONALITY:
There are some special functions that determine the
current loop iteration of a section. These are
rownum: current row, first row starting with 1
index: current row, first row starting with 0
odd: true if value is odd
even: true if value is even
mod: true if value is divisible by X
Examples:
{section name=month $var}
{if $month.rownum eq 4}
{* in 4th row of section loop *}
{/if}
{if $month.rownum.even}
{* current rownum is even *}
{/if}
{if $month.rownum.odd}
{* current rownum is odd *}
{/if}
{if $month.rownum.even.3}
{* each even row, grouped by 3.
so rows 1,2,3 are true (even),
4,5,6 are odd (false), etc *}
{/if}
{if $month.rownum.odd.3}
{* each odd row, grouped by 3.
so rows 1,2,3 are true (odd),
4,5,6 are even (false), etc *}
{/if}
{if $month.rownum.mod.4}
{* true if current row is divisible by 4 *}
{/if}
{/section}
THE {strip} TAG:
A special tag called {strip} can be used to strip out
extra space, tabs or newlines at the beginning and end
of each template row within {strip} and {/strip}.
For example:
<TR>
<TD>
<TT>
{section name=row $weekday}
{$row.weekday}&nbsp;
{/section}
</TT>
</TD>
</TR>
This will return unwanted results because of
the extra tabs and newlines contained within the <TT></TT>
tags. Normally to remedy this, you must run all
the lines together in the template like so:
<TR>
<TD>
<TT>{section name=row $weekday}{$row.weekday}&nbsp;{/section}</TT>
</TD>
</TR>
As you can see, this quickly makes the template unreadable.
An alternate solution is to use the {strip} tag like so:
<TR>
<TD>
{strip}
<TT>
{section name=row $weekday}
{$row.weekday}&nbsp;
{/section}
</TT>
{/strip}
</TD>
</TR>
What this will do is strip out tabs, spaces and newlines
at the beginning and end of each line before outputting
the results. This helps keep the template file readable
without affecting the output. Only text between {strip}
and {/strip} is affected.
{ldelim} AND {rdelim} TAGS:
These are used in the template to output the literal
left and right delimiters. Normally these are
"{" and "}" if you are using the default delimiters.
