 Posted: Mon Apr 26, 2010 6:05 pm Post subject: Retrospective variable setting / parsing |
 |
|
Hey smartys! 
I'm wondering if Smarty 3 offers any way of setting variable contents in retrospective.
An example will illustrate better:
| Code: |
<head>
<title>{$page.title}</title>
</head>
<body>
<!-- the following block will set the $page variable -->
{some_custom_block}
<h1>{$page.title}</h1>
<p>{$page.abstract}</p>
{/some_custom_block}
</body>
|
As you see the $page variable is first set in the block, but I need it's value up in the meta title as well.
Does smarty 3 offer any solution for this? and if not does any of you have any ideas on how to go about making it so?
Thanks in advance! |

Add an assign attribute to your block function which assigns the result to a Smarty variable instead of returning it like
| Code: |
if (empty($params['assign'])){
return $result;
} else {
$smarty->assign($params['assign'],$result);
}
|
Then in the template
| Code: |
{some_custom_block assign=foo}
<h1>{$page.title}</h1>
<p>{$page.abstract}</p>
{/some_custom_block}
<head>
<title>{$page.title}</title>
</head>
<body>
{$foo}
</body>

Thanks U.Tews, that's a good suggestion
I'm trying to avoid any extra markup and to moving the markup out of output context, though.
If keeping the markup like in my first post, is there any way of solving it so that the block mid-template can set the value for the variable in the beginning?
I've been looking into preFilters and that I might use them to rewrite the template to be like your suggestion. |
