Adding requirement for purchasing product

[Brewhaus]

We have a few products that we would like to add a check box that a customer must check in order to acknowledge a notice in order to purchase the item. There is a store wide 'conditions' option for the checkout, but we only require this for certain products. Is there any way to do this?

Read following thread here we discussed how to associate some custom field with product
viewtopic.php?f=44&t=9088

You can do something similar to collect input from customer.

I tried putting the new Edit Product files into the Admin/Products folder, and the ShowWarning file into the ConLib folder, but the warning does not show up anywhere on a product after checking the Enable Warning box for a product.

Also, I tried putting things back to the original state (replace the Edit Product files with the originals, and remove the ShowWarning file), and kept showing an IsWarning: true below the product description, so I had to modify the ProductCustomFieldsDialog file to stop that from showing. Because the ProductCustomFieldsDialog file is not in the ConLib/Custom folder, any updates will change the file back to its standard state, and the items will show the Is Warning text again. How can I correct this?

Would there be a way to make the check box so that a customer must accept the terms in order to add the item to their cart? We want to make sure that a customer is unable to add certain products to their cart without accepting the terms.

First product description page is showing warning information because you have added a new custom field which is stored in database in ac_ProductCutomFields table so removing website files will not remove it from database. If you want to remove it from database you need to manually delete it from database because right now AbleCommerce doesn't provide any way to add/delete product custom fields.

Secondly in order to make sure that custom can add products to cart only if he/she accepted the agreement, for this you need to make use of product templates. I think with this approach you will be in no need of ac_ProductCustomFields. All you need is to create a new product template with one customer field with type checkbox. Then enforce custom validation on this customer field so that it only consider it valid if its checked. Here is a link about how to enforce custom validation on customer side field.

Hopefully it will workout

Thank you, Mazhar. I had tried the product template before, but was not able to find a way to force the customer to respond to it in order to add the item to the cart.

The product template that I built describes the terms, and then has a check box (which says I Accept beside it). We do not need to have any input other than forcing the check box to be checked. How can we go about this?

[mazhar]

This is an easy one. First create a new product template let's say it Agreement, then create a new customer field keep its type Checkbox list and name it Agree. In prompt let say we placed Terms and Conditions and then add a new choice. In choice text field enter Do you agree? and then for its value enter Yes and save it.

Now all we need is to make this field required. As I suggested you to look at
viewtopic.php?f=42&t=11624

simply make changes to BuildProductChoices and add method ServerValidation as told in above post. Once you are done with above changes then you need to make it work with your product template. First of all change

Code: Select all

if (input.Name == "DateField")

to

Code: Select all

if (input.ProductTemplate.Name.Trim() == "Agreement" && input.Name.Trim() == "Agree")

and then adjust Date validation message here... message to your desired one for example it could be something like
Please accept terms and conditions required for this purchase..

Edit Made:- An update to this code is made to fix a compilation error

Finally all you need is to update ServerValidation method to only trigger validation if checkbox is unchecked. This required a little code copy/paste from collect template value method of product helper class. Anyhow working code according to above template example is this, just make your ServerValidation method look like this

Code: Select all

public static void ServerValidation(object source, ServerValidateEventArgs arguments)
    {
        bool isValid = false;

        // COLLECT ANY ADDITIONAL INPUTS
        Product product = ProductDataSource.Load(PageHelper.GetProductId());
        if (product != null)
        {
            if(product.ProductTemplate != null)
            {
                if (product.ProductTemplate.Name != "Agreement")
			return;
                ProductTemplate template = product.ProductTemplate;
                if (template != null)
                {
                    foreach (InputField input in template.InputFields)
                    {
                        //ONLY LOOK FOR CUSTOMER INPUT FIELDS
                        if (!input.IsMerchantField && input.Name == "Agree")
                        {
                            //SEE IF WE CAN LOCATE THE CONTROL
                            WebControl inputControl = (WebControl)PageHelper.RecursiveFindControl((source as CustomValidator).Page, input.UniqueId);
                            if (inputControl != null)
                            {
                                string value = input.GetControlValue(inputControl);
                                isValid = (value.Trim() == "Yes");
                            }
                        }
                    }
                }
            }
        }
        arguments.IsValid = isValid;
    }

                    {
                        ProductTemplateField itemInput = new ProductTemplateField();
                        itemInput.InputFieldId = input.InputFieldId;
                        itemInput.InputValue = input.GetControlValue(inputControl);
                        product.TemplateFields.Add(itemInput);
                    }
                }
            }
        }
    }
}

But when I use this file I get a runtime error on the website.

Sorry there was a small problem causing compilation problem in ServerValidation method. I just updated my post with ServerValidatoin method code to fix this problem. You can update your ServerValidation method with adjusted code.

[Brewhaus]

That seemed to work. Does it matter where the public static void ServerValidation(object source, ServerValidateEventArgs arguments) statement is placed in the file? As you can see I have it near the beginning. I assume that it makes no difference.

Also, I assume that I can follow the same steps to add another 'agreement' for different purposes just by changing the name of the agreement and the associated calls in the file?

[mazhar]

Regarding method defention you can add it any where in ProductHelper class just make sure that don't mix up its code with other functions. For example you can define it just above the last curly brace. Secondly yes you can change field name entry in script to make same script work for field with some other name.

Hi,
I have a similar problem.
For some product, I need the customer inserts some data in checkout fase.
Can I do something similar in the checkout pages?

[mazhar]

Yes possible out of the box. Simply create a product template with a customer field for example customer field of type textbox. Then apply this product template to desired product. This will make that input field available on product details page.

[giusepperiera]

What I need isn't a field in the details page but in the checkout form.
We sell services and we need custom data fields different for different type of products

[mazhar]

On checkout page you need to process basket items not products. Every basket item do have custom field collection like basketItems.CustomFields. You can make use of this feature, these custom fields are then copied over to orderITem.CustomFields on order completion. So after order placement you can process information via placed order.

[giusepperiera]

An other question.
Can I divide the checkout procedure in more than a page to collect data from customer like a wizard?

[mazhar]

OnePageCheckout makes use of different panels show/hide to get desired information. You can try to modify it to incorporate your custom information by modifying it. If you essentially want to have more then one pages then you will need to write some alternative checkout pages or have a look at Checkout Page with login. Just change your checkout page content template from OnePageCheckout to Checkout Page with login.

I recently noticed that, after our last upgrade, AC was not longer forcing the checkbox to be checked in order to add the item to the shopping cart. And, now that we are on 7.0.7 the method above does not seem to work. Could we get an update on the code necessary to force checking on the box in order to add the item to the shopping cart?

[Brewhaus]

Mazhar- are you able to help with this? I assume that we just need a modified version of the code above to work with the new version of AC, but I cannot figure out how to do it (and I have tried).

[ableExpert]

which AC version you were using before upgrading?

[Brewhaus]

If I recall it was 7.0.2.

[ableExpert]

I suspect after ac 7.0.4 version, database schema is changed for the Product template Fields.

[Brewhaus]

That is quite possible. The problem is that I cannot figure out how to resolve the issue / update the code to work with V 7.0.7. Any thoughts?

[ableExpert]

Well, I have updated the code.All you just need to replace this code in App_Code/ProductHelper.cs

Code: Select all

    public static void BuildProductChoices(Product product, PlaceHolder phChoices)
    {
        // ADD IN THE PRODUCT TEMPLATE CHOICES        
        foreach (ProductProductTemplate ppt in product.ProductProductTemplates)
        {
            ProductTemplate template = ppt.ProductTemplate;
            if (template != null && ppt.ProductTemplate.Name == "Agreement")
            {
                foreach (InputField input in template.InputFields)
                {
                    if (!input.IsMerchantField)
                    {
                        // ADD THE CONTROL TO THE PLACEHOLDER
                        phChoices.Controls.Add(new LiteralControl("<tr><td colspan=\"2\">"));
                        phChoices.Controls.Add(new LiteralControl((input.UserPrompt + "<br />")));
                        WebControl o = input.GetControl();
                        if (o != null)
                        {
                            phChoices.Controls.Add(o);
                            if (input.ProductTemplate.Name.Trim() == "Agreement" && input.Name.Trim() == "Agree")
                            {
                                CustomValidator customValidator = new CustomValidator();
                                customValidator.ID = "mycustomevalidator";
                                customValidator.ControlToValidate = string.Empty;
                                customValidator.ValidationGroup = "AddToBasket";
                                customValidator.ErrorMessage = "You need to agree to proceed further";
                                customValidator.Text = "*";
                                customValidator.ServerValidate += new ServerValidateEventHandler(ServerValidation);
                                phChoices.Controls.Add(customValidator);
                            }
                        }
                        phChoices.Controls.Add(new LiteralControl("</td></tr>"));
                    }
                }
            }
        }
    }

    public static void ServerValidation(object source, ServerValidateEventArgs arguments)
        {
            bool isValid = false;

            // COLLECT ANY ADDITIONAL INPUTS
            Product product = ProductDataSource.Load(PageHelper.GetProductId());
            if (product != null)
            {
                foreach (ProductProductTemplate ppt in product.ProductProductTemplates)
                {
                    if (ppt.ProductTemplate != null && ppt.ProductTemplate.Name == "Agreement")
                    {
                        ProductTemplate template = ppt.ProductTemplate;
                        if (template != null)
                        {
                            foreach (InputField input in template.InputFields)
                            {
                                //ONLY LOOK FOR CUSTOMER INPUT FIELDS

                                    //SEE IF WE CAN LOCATE THE CONTROL
                                    WebControl inputControl = (WebControl)PageHelper.RecursiveFindControl((source as CustomValidator).Page, input.UniqueId);
                                    if (inputControl != null)
                                    {
                                        string value = input.GetControlValue(inputControl);
                                        isValid = (value.Trim() == "Yes");
                                    }
                                }
                            }
                        }
                    }
                }
            }
            arguments.IsValid = isValid;
        }

I just tried this and the template (checkbox and text) disappeared.

[ableExpert]

Did you created your template with the name 'Agreement'?
