How to create form using Helper class

Mukesh Ravi · June 20, 2013

Hi Everybody,

I am creating a Module.

In which I have created a new Admin Tab and menus.

For menus I have created controller by extending "AdminTab" class.

Now I want create form in menu's controller file using Helper class.

But how can I use Helper in controller without extending "Module" class.

Is there any way to do this?

Please help me.....!!!!

Thanks

Hi,

If we understood you correctly, you need to check realization of BlockCms::initForm() function of blockcms module.

Best regards.

Thanks Valérie Assetskaya,

But your understanding for my question is wrong.

Here I am pasting my module's file code.

createadmintab.php

<?php

if(!defined('_PS_VERSION_'))

exit;

class createadmintab extends Module

{

public function __construct(){

$this->name = 'createadmintab';

$this->tab = 'front_office_features';

$this->version = '1.5';

$this->author = 'Mukesh G';

$this->need_instance = 0;

parent::__construct();

$this->displayName = $this->l('Create Admin Tab Module.');

$this->description = $this->l('Module shows how to create new admin tab then write code for module');

$this->confirmUninstall = $this->l('Are you sure you want to delete this module ?');

}

public function install(){

$parent_tab = new Tab();

$parent_tab->name = 'New Tab';

$parent_tab->class_name = 'AdminMainNewTab';

$parent_tab->id_parent = 0;

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

$parent_tab->add();

if (!parent::install()

|| !$this->installModuleTab('submenu1', array((int)(Configuration::get('PS_LANG_DEFAULT'))=>'submenu1'), $parent_tab->id)

|| !$this->installModuleTab('submenu2', array((int)(Configuration::get('PS_LANG_DEFAULT'))=>'submenu2'), $parent_tab->id)

|| !$this->installModuleTab('submenu3', array((int)(Configuration::get('PS_LANG_DEFAULT'))=>'submenu3'), $parent_tab->id))

return false;

return true;

}

public function uninstall()

{

if (!parent::uninstall()

|| !$this->uninstallModuleTab('submenu1')

|| !$this->uninstallModuleTab('submenu2')

|| !$this->uninstallModuleTab('submenu3')

|| !$this->uninstallModuleTab('AdminMainNewTab'))

return false;

return true;

}

private function installModuleTab($tabClass, $tabName, $idTabParent)

{

// $idTab = Tab::getIdFromClassName($idTabParent);

$idTab = $idTabParent;

$pass = true ;

@copy(_PS_MODULE_DIR_.$this->name.'/logo.gif', _PS_IMG_DIR_.'t/'.$tabClass.'.gif');

$tab = new Tab();

$tab->name = $tabName;

$tab->class_name = $tabClass;

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

$tab->id_parent = $idTab;

$pass = $tab->save();

return($pass);

}

private function uninstallModuleTab($tabClass)

{

$pass = true ;

@unlink(_PS_IMG_DIR_.'t/'.$tabClass.'.gif');

$idTab = Tab::getIdFromClassName($tabClass);

if($idTab != 0)

{

$tab = new Tab($idTab);

$pass = $tab->delete();

}

return($pass);

}

?>

submenu1.php

<?php

class submenu1 extends AdminTab{

private $module = 'createadmintab';

private $str = '';

private $url = '';

public function __construct(){

global $cookie;

$cont = 'submenu1';

$tkn = Tools::getValue('token');

$this->url ='index.php?controller='.$cont.'&token='.$tkn;

parent::__construct();

}

public function display()

{

echo $this->l('Here I want use Form using Helper form').'</p>';

}

?>

When you will install this module, In the backend area, tab is created with the link "submenu1".

When you click on this link my submenu1.php is called. my question is, i want to create form with the help of helper class.

So please solve my problem. If you have any other idea to create form through helper class, please share with us.

Thanks

Hello,

I am also facing this problem.

Is there any solution for this???

Mukesh Ravi · June 25, 2013

any Idea ????

Mukesh Ravi · June 27, 2013

Hello Valérie Assetskaya,

Did you checked my code ?

Alex Simonchik BelVG · June 30, 2013

Hi, Mukesh. Why do you use AdminTab class instead of AdminController class?

Alex Simonchik BelVG · July 1, 2013

Mukesh, please check code of this module. It is renders form with AdminController class.

Hello I have a question about the helpers

I need to create 2 forms, and I'm trying to do this using twice the helper class, the forms are created but I can't save any information if I show both of them.

I did this:

$html .= '<div id="tab-1">';

				$default_lang = (int)Configuration::get('PS_LANG_DEFAULT');
				$id_shop = (int)$this->context->shop->id;

				$fields_form[0]['form'] = array(
					'legend' => array(
						'title' => $this->l('Print Settings'),
						'image' => '../img/admin/cog.gif'
					),
					'input' => array(
						array(
							'type' => 'textarea',
							'label' => $this->l('Print Message'),
							'desc' => $this->l('Print Message display on the top of the printing page.'),
							'autoload_rte' => true,
							'lang' => true,
							'rows' => 10,
							'cols' => 100,
							'name' => 'contentPrint',
							'required' => false
						)
					),
					'submit' => array(
						'title' => $this->l('Save'),
						'class' => 'button'
					)
				);

				$helper = new HelperForm();
				$helper->module = $this;
				$helper->name_controller = $this->name;
				$helper->token = Tools::getAdminTokenLite('AdminModules');
				$helper->currentIndex = AdminController::$currentIndex.'&configure='.$this->name;
				$helper->languages = Language::getLanguages();
				$helper->default_form_language = $default_lang;
				$helper->allow_employee_form_lang = $default_lang;
				$helper->title = $this->displayName;
				$helper->show_toolbar = false;
				$helper->toolbar_scroll = true;
				$helper->submit_action = 'submitPrint';
				$helper->toolbar_btn = array(
					'save' => array(
						'desc' => $this->l('Save'),
						'href' => AdminController::$currentIndex.'&configure='.$this->name.'&save'.$this->name.
						'&token='.Tools::getAdminTokenLite('AdminModules'),
					),
					'back' => array(
						'href' => AdminController::$currentIndex.'&token='.Tools::getAdminTokenLite('AdminModules'),
						'desc' => $this->l('Back to list')
					)
				);

				$printObject = PrintObject::getByIdShop($id_shop);

				if (!$printObject) 
					$this->createExamplePrint($id_shop);

				$helper->fields_value['contentPrint'] = $printObject->contentPrint;

				$html .= $helper->generateForm($fields_form);
		

			$html .= '</div>';
			$html .= '<div id="tab-2">';


				$fields_form2[0]['form'] = array(
					'legend' => array(
						'title' => $this->l('Email Settings'),
						'image' => '../img/admin/cog.gif'
					),
					'input' => array(
						array(
							'type' => 'textarea',
							'label' => $this->l('Email Message'),
							'desc' => $this->l('Email Message display on the top of the email.'),
							'autoload_rte' => true,
							'lang' => true,
							'rows' => 10,
							'cols' => 100,
							'name' => 'content',
							'required' => false
						)
					),
					'submit' => array(
						'title' => $this->l('Save'),
						'class' => 'button'
					)
				);

				$helper = new HelperForm();
				$helper->module = $this;
				$helper->name_controller = $this->name;
				$helper->token = Tools::getAdminTokenLite('AdminModules');
				$helper->currentIndex = AdminController::$currentIndex.'&configure='.$this->name;
				$helper->languages = Language::getLanguages();
				$helper->default_form_language = $default_lang;

				$helper->toolbar_btn = array(
					'save' => array(
						'desc' => $this->l('Save'),
						'href' => AdminController::$currentIndex.'&configure='.$this->name.'&save'.$this->name.
						'&token='.Tools::getAdminTokenLite('AdminModules'),
					),
					'back' => array(
						'href' => AdminController::$currentIndex.'&token='.Tools::getAdminTokenLite('AdminModules'),
						'desc' => $this->l('Back to list')
					)
				);

				$emailObject = EmailObject::getByIdShop($id_shop);

				if (!$emailObject) 
					$this->createExampleEmail($id_shop);

				$helper->fields_value['content'] = $emailObject->content;

				$html .= $helper->generateForm($fields_form2);


			$html .= '</div>';
