Hi,

I pass an array to smarty.
The dump of this array is:

Code:
tab_authentification_ok = array (
  'url_redirection' => '/intranet/',
  0 => 'Bienvenue, Olivier Dofus',
  1 => 'Veuillez patientez, vous allez être redirigé vers l\'intranet',
)


Here's my very simple loop in my smarty template:

Code:
{foreach key=key item=item from=$tab_authentification_ok}
  {if $key neq 'url_redirection'}
  <p>OK =&gt; {$item}</p>
  {else}
  <h1>Key should be 'url_redirection' =&gt; {$key}</h1>
  {/if}
{/foreach}


The previous code should give:
Key should be 'url_redirection' => url_redirection
OK => Bienvenue, Olivier Dofus
OK => Veuillez patientez, vous allez être redirigé vers l'intranet

But it gives:

Key should be 'url_redirection' => url_redirection
Key should be 'url_redirection' => 0
OK => Veuillez patientez, vous allez être redirigé vers l'intranet

Am I missing something?
What am I doing wrong?

Damn I found it, but it's not logical to me. Here's the solution: ternary comparison (!==) instead of "neq".

This is not normal I think.

Code:
  {if $key !== 'url_redirection'}
  <p>OK =&gt; {$item}</p>
  {else}
  <h1>Key should be 'url_redirection' =&gt; {$key}</h1>
  {/if}

It is a PHP behavior between string and numeric comparison. Try the exact same thing in PHP code. (!= vs !==) Also !== is a comparison operator, not ternary.

Code:
// compare int to string
 if(0 != 'foo') { echo "ok"; } else { echo "what?"; }
