Validate form in a module

[Stiven Gallardo]

Good evening people, could someone help me with something, it turns out that I am creating a module in which I am displaying a form until everything is fine, but I would like to know how I can detect the sending of data from the form. in some php file of the module that I am developing, I would be very grateful if you help me

Hi @Stiven Gallardo,

I'm new to PrestaShop but maybe I can give you some hint.

If you've got a renderForm() method, you normally defined your submit button name here:

 protected function renderForm()
    {
        $helper = new HelperForm();

        $helper->show_toolbar = false;
        $helper->table = $this->table;
        $helper->module = $this;
        $helper->default_form_language = $this->context->language->id;
        $helper->allow_employee_form_lang = Configuration::get('PS_BO_ALLOW_EMPLOYEE_FORM_LANG', 0);

        $helper->identifier = $this->identifier;
        $helper->submit_action = 'submit_button';
        $helper->currentIndex = $this->context->link->getAdminLink('AdminModules', false)
            . '&configure=' . $this->name . '&tab_module=' . $this->tab . '&module_name=' . $this->name;
        $helper->token = Tools::getAdminTokenLite('AdminModules');

        $helper->tpl_vars = array(
            'fields_value' => $this->getConfigFormValues(), /* Add values for inputs */
            'languages' => $this->context->controller->getLanguages(),
            'id_language' => $this->context->language->id,
        );

        return $helper->generateForm(array($this->getConfigForm()));
    }

Then in the getContent() method, you can use the Tools::isSubmit method to check if you have to process data:

public function getContent()
    {
        /**
         * If values have been submitted in the form, process.
         */
        if (((bool) Tools::isSubmit('submit_button')) == true) {
            $this->postProcess();
        }

        $this->context->smarty->assign('module_dir', $this->_path);

        $output = $this->context->smarty->fetch($this->local_path . 'views/templates/admin/configure.tpl');

        return $output . $this->renderForm();
    }

In your postProcess() you handle form data:

protected function postProcess()
    {
        $form_values = $this->getConfigFormValues();

        foreach (array_keys($form_values) as $key) {
            Configuration::updateValue($key, Tools::getValue($key));
        }
    }

Here an example with data saved in Configuration table:

 protected function getConfigFormValues()
    {
        return array(
            'FIELD_ONE' => Configuration::get('FIELD_ONE', ''),
            'FIELD_TWO' => Configuration::get('FIELD_TWO', false)
        );
    }

Hope it can help you a little!

Hi 

Your idea seems very good, but isn't that to verify the form data in the administrative part?

Hi @Stiven Gallardo,

Sooorry I didn't read your topic right, you were talkin about a form displayed on the front?! Never tried this, I'm not gonna be much help. If you didn't already did it, you might wanna check another module with a front form to see how it behave.
