v2.2.3.1 trouble with core tag functionality with assign

Hi guys,
I can't seem to figure out what I am doing wrong with assign and calling it.
I'm using cms_selflink tag in my template:
{cms_selflink dir='prev' href='page_alias' assign='prev'} declared at the top and then:
Code: Select all
<div class="controls controls-prev"><a href="{$prev}"><i class="fa fa-chevron-left"></i></a></div>
The HTML output is nothing.

I'm also using the assign functionality on an image:
Code: Select all
{content_image block='stage_image' label='Stage Image' urlonly='1' exclude='thumb_' dir='images/stage' assign='stageimage'}
and {$stageimage} outputs nothing
--
Am I doing something wrong? I do have a {content} in the template and that seems fine but it seems that whenever I assign anything to it, it doesn't seem to render. Any insight would be greatly appreciated. Is there a cache I need to clear or something...? I see no errors but it just doesn't seem to do anything
...

Where in the template do you do the assign and where do you try to read the variabele?

(Note that the order is Top, Body, Head)

No output here either. I'm not sure if it's docs or code but {cms_selflink dir='prev' urlonly=1 assign='prev'} seems to work.

As mentioned, looks like scope.

For some reason, that worked. Thank you. Any way I can only have it go prev/next within siblings and if it's the last, "next" to go to the parent?

'page_alias' is supposed to be an existing page alias.
IIRC $page_alias variable contains the page alias of current page. So {cms_selflink href=$page_alias ...} should work too. Note that you should NOT enclose the $page_alias variable with quotes!

I'm not exactly sure what you mean by that but the cms_selflink tag can cover basic navigation...
Code: Select all
<h2>DEBUG</h2>
{cms_selflink dir='prev' urlonly=1 assign='x_prev'}
{cms_selflink dir='next' urlonly=1 assign='x_next'}
{cms_selflink dir='start' urlonly=1 assign='x_start'}
{cms_selflink dir='up' urlonly=1 assign='x_up'}
<p>prev={$x_prev}</p>
<p>next={$x_next}</p>
<p>start={$x_start}</p>
<p>up={$x_up}</p>
<hr>
{if empty($x_next)}
<p>Nowhere left to go. Might as well go back
{if {$x_up} != {$x_start}}
up: {$x_up}
{else}
home: {$x_start}
{/if}
</p>
{/if}
<hr>
... but if you want something funkier then you might be better off calling {Navigator} with a template to iterate through the node hierarchy and do stuff as appropriate.

lib/plugins/function.cms_selflink.php (2.2.5) shows a couple of undocumented dir options which might be handy;
prevpeer (or 'prevsibling')
nextpeer (or 'nextsibling')
... when these go empty you're at the start/end of level.
