has_content is_valid is_set

Tuesday 08 November 2005 4:53:26 am

Hi ,
can someone explain the differences of this template operators?

has_content is used in the embed/image.tpl but seems not to work and is not documentated:

{section show=$object.data_map.caption.has_content}

is_valid is also not documentated but worked in earlier versions than 3.6.1

is_set is well documentated, but did not work.

My aim is to test, if the attribute image of a class is filled or not.

Thanks for your help

Hi,
I have some problems concerning the new documentation, the deprecated template functions like section and the not documentated functions like has_content and the not working is_set and is_null :(

Here is the sample, the well known breadcrump in new template style, ok, the foreach loops works, but not the is_set and is_null:

first with is_set

{foreach $module_result.path as $index => $object}
	{if gt($index,1) }
		{if is_set( $object.url )}
			{$object.text|wash}  / 
		{else}
			<a href={$object.url|ezurl}>{$object.text|wash}</a> /
		{/if}
	{/if}
{/foreach}

and with is_null

{foreach $module_result.path as $index => $object}
	{if gt($index,1) }
		{if is_null( $object.url )}
			{$object.text|wash}  / 
		{else}
			<a href={$object.url|ezurl}>{$object.text|wash}</a> /
		{/if}
	{/if}
{/foreach}

The old template style was something like

{section name=Path loop=$module_result.path}
    {section show=$Path:item.url}
        {section show=is_set($Path:item.url_alias)}
            <a href={$Path:item.url_alias|ezurl}>{$Path:item.text|wash}</a> /
        {section-else}
            <a href={$Path:item.url|ezurl}>{$Path:item.text|wash}</a> /
        {/section}
    {section-else}
        {$Path:item.text|wash}
    {/section}
{section-else}
{/section}

Anybody knows?
