Aucun malaise, ce n'était pas un jugement ou une critique :-)
Tu peux surement utiliser ce bout de code
{if !$logged}
<form action="{$link->getPageLink('authentication', true)|escape:'html'}" method="post" id="login_form" class="six columns">
<fieldset>
<h3>{l s='Already registered?'}</h3>
<div class="form_content clearfix">
<p class="text">
<label for="email">{l s='E-mail address'}</label>
<span><input type="email" id="email" name="email" value="{if isset($smarty.post.email)}{$smarty.post.email|stripslashes}{/if}" class="account_input" /></span>
</p>
<p class="text">
<label for="passwd">{l s='Password'}</label>
<span><input type="password" id="passwd" name="passwd" value="{if isset($smarty.post.passwd)}{$smarty.post.passwd|stripslashes}{/if}" class="account_input" /></span>
</p>
<p class="submit">
{if isset($back)}<input type="hidden" class="hidden" name="back" value="{$back|escape:'htmlall':'UTF-8'}" />{/if}
<input type="submit" id="SubmitLogin" name="SubmitLogin" class="button radius" value="{l s='Log in'}" />
</p>
<p class="lost_password"><a href="{$link->getPageLink('password')}">{l s='Forgot your password?'}</a></p>
</div>
</fieldset>
</form>
{/if}
Ah ben t'avais déjà trouvé, j't'ai rajouté le !$logged
:-)
