Module for extra carrier text field in checkout

[pl.sabotinov]

 Hello everybody,

Presta 1.7.7.5

i am newbie in creating modules, but still have decided to solve one small problem by creating a very simple module, which adds 2 fields in the carrrier / checkout step. These fields are saved in the ps_orders table and will be used and displayed on the new order mail template. But the problem is that i can not display the two input text fields in the carrier step of FO. So i can not fill the fields with information. Here the code of my main class:

Full text is attached below as text file  as cloudflare blocks the post with code even in code tags

 

 

I am using the hookdisplayAfterCarrier - to display the text fields there. But in the FrontOffice at the position where these text fields should be displayed i receive only: Array 

 

And in console the html generated is: 

in text file also below

So the example where i have taken the code this definition is put in constructor in the override of class. But i do not want to make this override. Should i put this definition in constructor of my main class also?

Would you help me please to display these fields in FO. I hope the other part of the code is correct. What concerns the database - the fields are added there. They are in orders table, when i install module.

Hello again,

 

i think i've found the problematic part of my code. So in my function:

public function hookDisplayAfterCarrier($params) {
 
        return [
                    (new FormField)
                    ->setName('my_extrafield_1')
                    ->setType('text')
                    //->setRequired(true)
                    ->setLabel($this->l('My extrafield carrier branch 1')),
                    (new FormField)
                    ->setName('my_extrafield_2')
                    ->setType('text')
                    ->setLabel($this->l('My extrafield carrier branch 2'))
        ];

if i replace it with (example):

public function hookDisplayAfterCarrier($params) {

$this->context->smarty->assign([
			'greetingsFront' => 'Hello Front from MyExtraCarrierBranch !',
		]);

		
		return $this->display(__FILE__, 'my-front-template.tpl');
}

and create one simple my-front-template file. It outputs exactly on the place of the hook this message "Hello....". So it seems that the form (new FormField) that is created here is not created/accepted by Prestashop. as far as i have seen in other modules, there is no need even to create a tpl file for this form. Should be created and displayed by prestashop. So am i wrong, or how should i force creating the input form fields in the front?

I think i found the rerason. Actually it is obvious, but still i just took too much from the example module. So with the function:

public function hookDisplayAfterCarrier($params) {
 
        return [
                    (new FormField)
                    ->setName('my_extrafield_1')
                    ->setType('text')
                    //->setRequired(true)
                    ->setLabel($this->l('My extrafield carrier branch 1')),
                    (new FormField)
                    ->setName('my_extrafield_2')
                    ->setType('text')
                    ->setLabel($this->l('My extrafield carrier branch 2'))
        ];

i am trying to create new field in the form. But here in this Step, where my hook is, there is no html form created by Prestashop. So not possible to create a new field. Would someone please suggest me how can create (easiest method) a simpe form here at this place (after carriers list) with this both fields. I suppose i should also register my module in the hook carrier processing, or order processing, where i should make the insert of these values in the db table. Because there is no function in presta that will do it for this new form i suppose.

There is one last thing that i need some help. If i create a form in a custom template file (template file generated in my module):

 

<form class="clearfix" id="configuration_form" data-url-update="{url entity='order' params=['ajax' => 1, 'action' => 'selectDeliveryOption']}" method="post">
   <div class="panel" id="fieldset_0">
      <div class="form-wrapper">
         <div class="form-group">
            <label for="myextrafield_id">{l s='Carrier branch additional Address or Name(option): '}</label>
							<input type="text" id="my_extrafield_1" name="my_extrafield_1" size="50" maxlength="120" value="" />
			<label for="my_extrafield_2">{l s='Carrier branch additional Address or Name(option): '}</label>
							<input type="text" id="my_extrafield_2" name="my_extrafield_2" size="50" maxlength="120" value="" />
							<input type="submit" value="Submit">
         </div>
      </div>
   </div>
</form>

Am i able to get the value of the input field: my_extrafield_1 within php file of my module with the Tools::getValue('my_extrafield_1')? Because when i try to do this the value is empty. Of course it depends when is the hook displayHeader executed - only once in beginning or each time when moving trough the order steps? I just want to display the value there to be sure that it is saved and accesible in $_POST array of vars.
