problem with Tools::getValue() Get value of select menu

[vitochueng]

Hello,

 

I tryed with Tools::getValue() to get value from select menu in product page, but it doesn't work...

 

-----------------------         codes in the add to cart form at product.tpl :

 

                                    <select name="char_color" id="attr_char_color">

                                                <option value="None"  selected="selected">Select  Color</option>

                                                <option value="Black">Black</option>

                                                <option value="Ivory">Ivory</option>

                                                <option value="White">White</option>

                                                <option value="Brown">Brown</option>

                                                <option value="Burgundy">Burgundy</option>

                                    </select>

 

-----------------------         and codes in CartController.php:

 

protected $char_color;

 

public function init()

{

parent::init();

 

// Send noindex to avoid ghost carts by bots

header("X-Robots-Tag: noindex, nofollow", true);

 

// Get page main parameters

$this->id_product = (int)Tools::getValue('id_product', null);

$this->id_product_attribute = (int)Tools::getValue('id_product_attribute', Tools::getValue('ipa'));

$this->customization_id = (int)Tools::getValue('id_customization');

$this->qty = abs(Tools::getValue('qty', 1));

$this->id_address_delivery = (int)Tools::getValue('id_address_delivery');

$this->char_color = (string) Tools::getValue('char_color');

 

}

 

 

But the value $this->char_color is empty, does anyone here can help me?

Tools::getValue() only get the values after a POST or GET, to be clear, in this case you will get these value, only when the form is submitted, and I think you are in the wrong function.

I have submitted the form. But the Tools::getValue()  method cached nothing...

I think you are trying to catch it in the wrong function, you need provide more code to help you.

I think you are trying to catch it in the wrong function, you need provide more code to help you.

 

I changed the code :

 

               $this->char_color = (string) Tools::getValue('char_color');

 

to :

 

                        if (Tools::getValue('char_color'))

                                    $this->char_color = (string) Tools::getValue('char_color');

                        else

                                    $this->char_color = 'none';

 

Always get the value 'none'. As you said, maybe I caught it in wrong function.  

I just want to catch the value of select memu when click the 'add to cart' button. Do you know which function should I use? In controllers\front\CartController.php or classes\Cart.php ? Thanks

[Rolige]

Maybe you can find it on blockcart module, I'm now on my phone.

[vekia]

are you sure that your form is posted?

try to use print_r($_POST); and see if there is an array of posted variables.

Thanks for your advice. I put the print_r($_POST); at  CartController.php: init() function.  And I got the information below:

 

Array ( [controller] => cart [add] => 1 [ajax] => true [qty] => 1 [id_product] => 1 [token] => 27b35e59bff8619e4e6fe90f423d97ac )

 

The select option was never posted.  Cloud you tell me how to solve this issue?

 

Thanks

[vekia]

so as you can see your form isn't posted

where is the post button / command? 

how you use this form to post it?

I only put the codes below in the add to cart form at product.tpl, nothing else was changed in product.tpl...  Am I right? 

 

    <select name="char_color" id="attr_char_color">

                                                <option value="None"  selected="selected">Select  Color</option>

                                                <option value="Black">Black</option>

                                                <option value="Ivory">Ivory</option>

                                                <option value="White">White</option>

                                                <option value="Brown">Brown</option>

                                                <option value="Burgundy">Burgundy</option>

    </select>

you are likely using ajax cart, and the javascript is likely not aware of your "custom" attribute.

Yes, I'm using ajax cart. Can you tell me which js file should I modify?

 

Thanks

[bellini13]

i would start by looking at blockcart module

[3cubes]

You have to customize ajax-cart.js file in .../modules/blockcart/ and tell him to send your custom form data along with standard data when add to cart button is pressed.

i got it upto this. i cannot insert posted custom value in database. (i've created custom field in ps_cart_product)

 

i tried custom field to db code in Cart.php at 966

$result_add = Db::getInstance()->insert('cart_product', array(
					'id_product' => 			(int)$id_product,
					'id_product_attribute' => 	(int)$id_product_attribute,
					'id_cart' => 				(int)$this->id,
					'id_address_delivery' => 	(int)$id_address_delivery,
					'id_shop' => 				$shop->id,
					'quantity' => 				(int)$quantity,
					'date_add' => 				date('Y-m-d H:i:s'),
					'pack_content' => 			$customPack_value
				));

// where 'pack_content' and $customPackValue are my codes. 

 if i press add to cart button, no value added to db field
