 Posted: Tue Nov 17, 2009 4:21 pm Post subject: Smarty 3: {assign} overwrites $smarty->assign |
 |
|
We have a little problem here with the assign.
We have a $smarty object, which we give a little function, which should set 'foobar' to the variable.
| Code: | $smarty->register_function('little_func', 'little_func');
function little_func($params, $smart) {
$smart->assign($params['assign'], 'foobar');
}
|
In the Template we have the following code.
| Code: | {assign var="foo" value="bar"}
value: {$foo}<br />
{little_func assign="foo"}
value: {$foo}
|
The expected output would be
| Code: | value: bar<br />
value: foobar |
but we get
| Code: | value: bar<br />
value: bar |
I don't think, that this is normal, espacially, we did not find any hint in the documentation, that assign overrules the $smarty->assign. |

This is a situation that is not BC with Smarty 2, and has not been implicitly documented yet.
With Smarty 3, the current template is it's own object, so assigning the var to $smarty (the global object) will not see the change locally. What you need to do is assign the var to the local template object, which is the 3rd param in Smarty 3:
| Code: | function little_func($params, $smarty, $tpl) {
$tpl->assign($params['assign'], 'foobar');
} |

| Well that wasn't completely correct. This situation only happens if you are assigning an already-assigned var. If you assign a (new) global var, the local tpl should pick it up. The search order is local, if not found, then next up the chain, etc. until global is reached. |
