signin form on header

[PrestaMathieu]

Hello,
 I would like to add the signin form on the header of my website ( instead of links).

I have test to use code of authentification.tpl but it's not working. the form is diplay ok but when I valid, I am redirect to login page

I have an other bug : Is it the same variable with Prestashop 1.7 because when I add a condition like {if $logged} {/if} I have an error !

 

Do you have any idea ?

 

my code bellow (on header.tpl):

 

Thanks a lot.

				 <form action="{$link->getPageLink('authentication', true)|escape:'html'}" method="post" id="login_form" class="six columns"> 
						
				<fieldset>
					<h3 style=" font-size:12px; color:black;">{l s='Identifiez-vous'}</h3>
