Correct way to check if an array element exists

Tuesday 15 March 2005 4:10:49 am

Hi,

I'm using the following template code to decide which option in a drop down box that should be selected:

{section name=Child loop=$partner_accounts}
<option value="{$:key}"  {switch match=$level.partner_objects[$:key]}{case match=true}SELECTED{/case}{case}{/case}{/switch}>{$:item}</option>
{/section}

The code works fine, but the debug gives the following error:

No such attribute for array(1): *$:key*

Of course, the attribute with the specific key will not always be present, and that's exactly the purpose of the check. So, how can I make my code "debug-friendly"?

Sincerely,

Actually, the template function is: <b>is_set()</b>. The isset() function is the PHP variant.
