Module front controller - Template extends customer/page - Fatal error

[bdesprez]

Hi,

I have some difficulties to create a module front controller.

Everithing seems fine (I used another controller of my module to create this one) but I have a fatal error …
Type error: Argument 1 passed to smartyClassnames() must be of the type array, null given, called in /var/www/ps-bruno/classes/Smarty/SmartyLazyRegister.php on line 83

The controller is placed in «xlpos/controllers/front/Ventesc.php»:

class XlposVentescModuleFrontController extends ModuleFrontController
{
    public $auth = true;
    public $guestAllowed = false;

    /**
     * @throws PrestaShopException
     * @throws Exception
     * @see FrontController::initContent()
     */
    public function initContent()
    {
        parent::initContent();
        $this->setTemplate('module:xlpos/views/templates/front/1_7_ventesc.tpl');
        $this->context->smarty->assign([
            'liste_ventes' => [],
            'page' => 1
        ]);
    }

}

The template is placed in «xlpos/views/templates/front/1_7_ventesc.tpl» :

{extends file='customer/page.tpl'}

{block name='page_title'}
    {l s='Purchases' mod='xlpos'}
{/block}

{block name='page_content'}
    <h6>{l s='Purchases you have made on the web AND in our shops:' mod='xlpos'}</h6>
    {if $liste_ventes && count($liste_ventes)}
        <table class="table table-striped table-bordered hidden-sm-down">
            <thead class="thead-default">
            <tr>
                <th>{l s='Purchase' mod='xlpos'}</th>
                <th>{l s='Date' mod='xlpos'}</th>
                <th>{l s='Amount' mod='xlpos'}</th>
                <th>{l s='View purchase' mod='xlpos'}</th>
            </tr>
            </thead>
            <tbody>
            {foreach from=$liste_ventes item=vente}
                <tr>
                    <td>{$vente->vcentete_type|capitalize} #{$vente->vcentete_num}</td>
                    <td scope="row">{dateFormat date=$vente->vcentete_date full=0}</td>
                    <td>{Tools::displayPrice($vente->vcentete_totalttc)}</td>
                    <td class="text-sm-center"><a href="#todo"><i class="material-icons"></i></a></td>
                </tr>
            {/foreach}
            </tbody>
        </table>
    {else}
        <aside class="notifications">
            <div class="container">
                <article class="alert alert-warning" role="alert" data-alert="warning">
                    <ul>
                        <li>{if $page === 1 }
                                {l s='You don\'t have any purchase!' mod='xlpos'}
                            {else}
                                {l s='No more purchase!' mod='xlpos'}
                            {/if}</li>
                    </ul>
                </article>
            </div>
        </aside>
    {/if}
    <nav aria-label="{l s='Purchase navigation' mod='xlpos'}">
        <ul class="pagination justify-content-center">
            <li class="page-item {if $page === 1 }disabled{/if}">
                <a class="page-link"
                   href="{$link->getModuleLink('xlpos', 'VentesCentralisees', ['page' => $page - 1], true)|escape:'htmlall':'UTF-8'}"
                   tabindex="-1" {if $page === 1 }aria-disabled="true"{/if}>{l s='Newer' mod='xlpos'}</a>
            </li>
            <li class="page-item">{$page}</li>
            <li class="page-item {if count($liste_ventes) === 0 }disabled{/if}">
                <a class="page-link"
                   href="{$link->getModuleLink('xlpos', 'VentesCentralisees', ['page' => $page + 1], true)|escape:'htmlall':'UTF-8'}"
                   {if count($liste_ventes) === 0 }aria-disabled="true"{/if}>{l s='Older' mod='xlpos'}</a>
            </li>
        </ul>
    </nav>
{/block}

My module listen the hook «displayCustomerAccount» and add 2 buttons :
 

<!-- Module xlpos loyalty -->
<a class="col-lg-4 col-md-6 col-sm-6 col-xs-12" id="xlpos-loyalty-link"
   href="{$link->getModuleLink('xlpos', 'Loyalty', ['id_externe' => $id_externe, 'identfidelite' => $identfidelite], true)|escape:'htmlall':'UTF-8'}"
   title="{l s='My loyalty' mod='xlpos'}" rel="nofollow">
    <span class="link-item">
        <i class="material-icons">&#xE89A;</i>
        {l s='My loyalty' mod='xlpos'}
    </span>
</a>
<!-- /Module xlpos loyalty -->
<!-- Module xlpos purchases -->
<a class="col-lg-4 col-md-6 col-sm-6 col-xs-12" id="xlpos-ventesc-link"
   href="{$link->getModuleLink('xlpos', 'Ventesc', ['page' => 1, 'id_externe' => $id_externe, 'identfidelite' => $identfidelite], true)|escape:'htmlall':'UTF-8'}"
   title="{l s='My purchases' mod='xlpos'}" rel="nofollow">
    <span class="link-item">
        <i class="material-icons">&#xE889;</i>
        {l s='My purchases' mod='xlpos'}
    </span>
</a>
<!-- /Module xlpos purchases -->

The «displayCustomerAccount» hook works fine (see ps_cust.jpg).

But when I click on «My Purchases» I have an error (see error.jpg).
I tried to clean the cache.

When I remove the extends part of the template, the page is loaded … But it's ugly (the HTML contains only elements of the template file).

Sooo,

I think I found the solution …
DO NOT PUT «page» in the smarty assign …

I replaced «page» by «num_page» and I now it works …

It's good to know …
