<!-- No user name, no table row -->
{/if}
The condition tested in the
{if} … {/if}
block should be a valid PHP expression. The
{else}
tag does not require a
closing tag.
Script Blocks
The brace characters
{
and
}
are specially handled by the Smarty template engine. Using text that contains these
characters, such as CSS and JavaScript blocks, requires a Smarty block
{literal} … {/literal}
:
<script type="text/javascript" language="JavaScript">
{literal}
<!--
function my_function() {
// some Javascript code here
}
// -->
{/literal}
</script>
Failing to include the
{literal}
tag will result in a Smarty syntax error when using your template. Single instances of
a
{
or
}
character can be replaced with the Smarty syntax
{ldelim}
and
{rdelim}
respectively.
Repeated Text Blocks
To repeat a block of text for each item in a collection, use the
{section} … {/section}
tag:
{section loop=$collection name=i}
<tr>
<td class="nwaBody">
{$collection[i].name}
</td>
</tr>
{sectionelse}
<!-- included if $collection is empty -->
{/section}
The content after a
{sectionelse}
tag is included only if the
{section}
block would otherwise be empty.
Foreach Text Blocks
An easier to use alternative to the
{section} … {/section}
tag is to use the
{foreach} … {/foreach}
block:
{foreach key=key_var item=item_var from=$collection}
{$key_var} = {$item_var}
{foreachelse}
<!—included if $collection is empty -->
{/foreach}
The advantage of this syntax is that each item in the collection is immediately available as the named item variable,
in this example
{$item_var}
. This construct is also useful when iterating through associative arrays indexed by key,
as the key is immediately available with each item.
A
name=
attribute may be supplied with the opening
{foreach}
tag. When a name is supplied, the following
additional Smarty variables are available for use inside the
{foreach} … {/foreach}
block:
l
{$smarty.foreach.
name
.first}
– true if the item being processed is the first item in the collection
l
{$smarty.foreach.
name
.last}
– true if the item being processed is the last item in the collection
l
{$smarty.foreach.
name
.index}
– counter for the current item, starting at 0 for the first item
l
{$smarty.foreach.
name
.iteration}
– counter for the current item, starting at 1 for the first item
l
{$smarty.foreach.
name
.total}
– value indicating the total number of items in the collection
