smarty throwing error on using $smarty.post

Question

We are using smarty as template system for one of our form, please check add/edit form code...

<form action="{$MAIN_URL}products/add" method="post" class="clearfix">
<input type="text" name="cname" value="{if $smarty.post.cname}{$smarty.post.cname}{elseif $editdetails.product_name}{$editdetails.product_name}{/if}" />

its throwing following error...

Undefined variable: post in <b>/root/smarty/libs/sysplugins/smarty_internal_data.php</b> on line 291

It works fine if we remove {if $smarty.post.cname}{$smarty.post.cname} please help to fix. thanks.

Answer 1

I think it should be

{if isset($smarty.post) && isset($smarty.post.cname)}

but for the sake of brevity, this should work

{if isset($smarty.post.cname)}{$smarty.post.cname}{elseif $editdetails.product_name}{$editdetails.product_name}{/if}

Answer 2

Rather than {$smarty.post.cname} , is your variable actually called {$post.cname} ? You other {$editdetails} would seem to imply that.

This assumes that $smarty is the PHP Smarty object variable, and not a template variable.
