smarty problem when assign variable

Question

Fatal error: Smarty error: [in rezultati/index.tpl line 24]: syntax error: $smarty. is an unknown reference (Smarty_Compiler.class.php, line 2164) in D:\HTTPSERVER\wwwroot\kajak\sistem\smarty\libs\Smarty.class.php on line 1093


{assign var="file" value="{$smarty.const.CMS_URL_POT}/moduli/rezultati/files/{$rezultat.datoteka|ss}"}
            {if file_exists($file)}
                <a href="{$file}" target="_blank">{$smarty.const.REZULTATI_025}</a> 
            {/if}

Why this is not valid: {assign var="file" value="{$smarty.const.CMS_URL_POT} and $rezultat.datoteka|ss. |ss is not recogniozed when using assign..

Use backticks (instead of braces) around the variable:

`$smarty.const.CMS_URL_POT`

From the manual:

Smarty will recognize assigned variables embedded in "double quotes" so long as the variable name contains only numbers, letters, under_scores and brackets[]. See naming for more detail.

With any other characters, for example a .period or $object>reference, then the variable must be surrounded by backticks.

Thx i will try. Why to use ` (backticks)?

@senzacionale: That's just how smarty requires it. It's most likely related to PHP's requiring of braces when interpolating multidimensional arrays in a string. I've added a link to the relevant manual page.

thx for help. i also found that in manual. What about $rezultat.datoteka|ss. i can not use |ss and backticks. if using just $rezultat.datoteka then works but if i add |ss then not working any more when using assing.

They show an example: {func var="test ``$foo.bar`` test"|escape}

Whoops. Those should be single backticks in my comment above.

Maybe you should try using backticks if you want the constant treated as part of the $smarty variable, take this as an example:

{assign var="myvar" value="20"}
{* myCONST = 'test'  - assuming you have a const defined somewhere *}

{assign var="file" value="(`$smarty.const.myCONST`/moduli/rezultati/files/`$myvar`)"}
{$file} {* should return "test/moduli/rezultati/files/20 *}

Not exactly sure what you want to achieve but I hope this gives you the idea.
