Prestashop admin module tpl issue

Question

I'm working on a prestashop custom module development, my idea is to create a custom export module, I'm able to install the module and add the menu under catalog menu. the only issue is while installing the tpl files not copying to the admin template folder ? Should we copy these view with copy method inside install section of module ?

in my controller I'm trying to load the tpl file from

public function initContent() {
        parent::initContent();
        $smarty = $this->context->smarty;
        $smarty->assign('test', 'test1');
        $this->setTemplate('wwmexport/wwmexport.tpl');


    }

This path file is not exist after module installation $this->setTemplate('wwmexport/wwmexport.tpl'); when I create it manually everything works fine.

I need to know is there any option to load the tpl from my module path something like below.

return $this->display(_PS_MODULE_DIR_ . 'wwmexport/views/templates/admin/wwmexport.tpl');

but that not working :(

My module structure is as follows.

wwmexport
  controllers
    admin
     Adminwwmcontroller.php
  views
    templates
      admin
          wwmexport.tpl

  wwmexport.php

controller file have

class AdminWwmExportController extends AdminController {

    protected $module;

    public function __construct() {

        parent::__construct();

    }

    public function display() {

        parent::display();

    }


    public function initContent() {

        if (Tools::getValue('method') != "") {
            $method = Tools::getValue('method');
            $this->$method();
        }

        parent::initContent();
        /*$smarty = $this->context->smarty;
        $smarty->assign(array('test', 'test1'));*/
        //$this->setTemplate('wwmexport.tpl');
        global $smarty;
        $smarty->display(_PS_MODULE_DIR_ . 'wwmexport/views/templates/admin/wwmexport.tpl');

    }
}

my module file wwmexport.php as follows.

class WwmExport extends Module {

    public function __construct() {
        $this->name = 'wwmexport';
        $this->tab = 'export';
        $this->version = '1.0.0';
        $this->author = 'Jobin Jose';
        $this->need_instance = 0;
        $this->ps_versions_compliancy = array('min' => '1.6', 'max' => _PS_VERSION_);
        $this->bootstrap = true;

        parent::__construct();

        $this->displayName = $this->l('Export');
        $this->description = $this->l('Custom Export Features for Products');
        $this->confirmUninstall = $this->l('Are you sure you would like to uninstall?');
    }

    public function install($delete_params = true) {

        if (!parent::install()
            /*|| !copy(_PS_MODULE_DIR_ . 'wwmexport/views/templates/admin/wwmexport.tpl', _PS_ADMIN_DIR_ . '/themes/default/template/wwmexport.tpl')*/
            || !$this->installModuleTab('AdminWwmExport', array(1 => 'Product Export'), 9)
        ) {
            return false;
        }

        return true;
    }

    public function uninstall() {
        if (!parent::uninstall()
            || !$this->uninstallModuleTab('AdminWwmExport')) {
            return false;
        }

        return true;
    }

    private function installModuleTab($tabClass, $tabName, $idTabParent) {
        $tab = new Tab();

        $tab->name = $tabName;

        $tab->class_name = $tabClass;

        $tab->module = $this->name;

        $tab->id_parent = $idTabParent;

        if (!$tab->save()) {
            return false;
        }

        return true;

    }

    private function uninstallModuleTab($tabClass) {
        $idTab = Tab::getIdFromClassName($tabClass);

        if ($idTab != 0) {

            $tab = new Tab($idTab);

            $tab->delete();

            return true;

        }

        return false;

    }

}

Solved

rewrite the initContent() as follows.

public function initContent() {    

        parent::initContent();
        $smarty = $this->context->smarty;
        $content = $smarty->fetch(_PS_MODULE_DIR_ . 'wwmexport/views/templates/admin/wwmexport.tpl');
        $this->context->smarty->assign(array('content' => $this->content . $content));

    } 

Answer 1

so it works for me

$this->display(__FILE__ , 'views/templates/admin/wwmexport.tpl');
