Hello, trying to add a custom field in the product page on Odoo 14 e-commerce and I'm not able to retrieved posted form field from the router:


Product XML (website_sale.product):

input type="text" class = "form-control or_website_form_input" name = "x"/

Http router:

@http.route(['/shop/cart/update'], type='http', auth="public", methods=['POST'], website=True)    
def cart_update(self, product_id, add_qty=1, set_qty=0, **kw):
"""This route is called when adding a product to cart (no options)."""
print ("KW= ",kw) # simply printing the posted items

... rest of the code


Console output:

KW=  {'quantity': '1', 'product_custom_attribute_values': '[{"custom_product_template_attribute_value_id":6,"attribute_value_name":"Date","custom_value":""}]', 'variant_values': '3', 'no_variant_attribute_values': '[]'}

I suspect that the problem is with the definition of the input class?


Thanks

Please post your XML code as well.

Its a simple with the

tag like this:

 input type="text" class = "form-control or_website_form_input" name = "x"/

Did you add your input field inside the form or somewhere else?

Please post your inherited XML code so that we can check the root cause.

the website_sale.product view includes the following form to add to cart:

<form t-if="product._is_add_to_cart_possible()" action="/shop/cart/update" method="POST">

...

### so I added just an additional input field to the existing form:###

input type="text" class = "form-control or_website_form_input" name = "x"/

<a role="button" id="add_to_cart" class="btn btn-primary btn-lg mt16 js_check_product a-submit d-block d-sm-inline-block" href="#"><i class="fa fa-shopping-cart"/> Add to Cart</a>

</form>

ok so you have directly made the change in the standard module. Did you upgrade the website_sale module after the change?

Yes, I've made the change into the standard module first to make sure its works then I will write a custom module.

It seems that there is a JS somewhere that is striping any additional <input>s before its calling the controller

and yes I did upgrade the website_sale after the changes

after some investigation, the following js has the answer:

/addons/website_sale/static/src/js/website_sale.js
Function: _handleAdd

You need to add the custom form field into this block:

self.rootProduct = {                product_id: productId,                quantity: parseFloat($form.find('input[name="add_qty"]').val() || 1),                self.getCustomVariantValues($form.find('.js_product')),                variant_values: self.getSelectedVariantValues($form.find('.js_product')),                no_variant_attribute_values: self.getNoVariantAttributeValues($form.find('.js_product'))            }; 

then you will be able to retrieve the value of the custom field in the controller using the kw.
