Is array in smarty returns error

Question

Fatal error: Uncaught exception 'SmartyCompilerException' with message 'Syntax Error in template "./templates/diet-report.tpl" on line 3 "{if is_array($dietcontent) }" - Unexpected " }"' in ...

I did this:

    {if is_array($dietcontent) }
    There is something..
    {else}
    Noope...
    {/if}

When i output {$dietcontent} i get "Array". But on pages where i dont get "Array" I wish to output a text.

Why am i getting error?

I even tried in my controller (this above is in template) :

$data['rapportExists'] = is_array($data['dietcontent']) ? true: false;

and then in my template:

{if $rapportExists == false }
noope
{/if}

Still receives the same error unexpected }

Answer 1

You need to remove the space before }. Smarty will not permit whitespace before a closing brace, or after an opening brace. I tested this in some of my own templates and could reproduce your error by placing a space before the closing brace.

{if is_array($dietcontent) }
-------------------------^^^

{if $rapportExists == false }
---------------------------^^^

Answer 2

You can do it like:

{if $yourArray|is_array}
do something with it
{/if}
