Unhide custom field after updating in view

I have two Order custom fields.

• Do you have a serial number? Yes/No
• Serial Number

If there is an existing value for the coupon, you have to change the first custom field value to yes.
Are you using, radio button ? Could you give us a link to that page, and a test account ?

Yeah sure, I didn't actually have this on the live site yet but I have now partially added the feature so we can test it.

www.calxa.com.au/index.php?Itemid=69&opt...=product&layout=show

Add any product to the cart then login as:
Username: hika
Password: hika

The second step in the checkout is titled Serial Number. You will note there are two front end visible fields labeled;
Do you have a serial number?
Serial Number

The 'Serial Number' fields is configured to display only when 'Do you have a serial number?' = 'Yes'

Using the hika user these fields will be populated with Yes and ThisIsASerialNumber, however the second field is not shown until you click on Yes.

In the view "checkout / step", at the end of the file try to add the javascript:

var serialNumber = document.getElementById('hikashop_order_order_serial_number');
if(serialNumber.value != '') serialNumber.style.display = 'inherit';

I have added the script but it has not changed. I also temporarily added window.alert(serialNumber.value); which returned undefined.

Is there something wrong with the syntax for serialNumber.value to return undefined?

Further to my other question regards the display of a single field, I have now also made customisations to the "checkout\fields" view. The purpose of this change is to not display the "custom_fields" at all if they are not required. Instead I am just displaying some text explaining that new serial numbers must be issued.

This is causing a problem though because I can't proceed to the next step. A message is displayed saying:

Please fill the Do you have an existing Calxa serial number? field.

I don't understand why this is when a default value of "no" should be set. If I output the value of $this->order->order_existing_serial it says "no", yet the error message suggests it is not populated.

If you would like to reproduce this to see it in action you will need to add two different but not including Monthly Subscription products to the cart. You should then get the scenario where the custom order fields are not displayed.

One step closer but still not quite there. It is at least recognising the serial number value now, however the style.display = 'block' does not seem to change anything. I have updated the script on the live site so you can check it out.

As a test I also removed the option to limit the display of this field. Then is I changed the 'block' to 'none' and I could see the changes reflected, so we no the script is now being correctly called. Having said this the field is still not shown when you first display the custom fields (Serial Number) step. My thoughts are that this script is being called too early and then the limit display option comes in after this one and hides it again. What script handles the conditional display of that field normally?

Sorry Still no luck with the new script.

Do you need some more information?

Thank you much appreciated, this has now worked.

However as we got tied up in this problem we have left another question problem alone. I let it go because I figured it would be easier to focus on one at a time.

Anyway here is the details of my other problem. I have now also made customisations to the "checkout\fields" view. The purpose of this change is to not display the "custom_fields" at all if they are not required. Instead I am just displaying some text explaining that new serial numbers must be issued.

www.calxa.com.au/index.php?option=com_hi...ayout=show&Itemid=69

On this page add the Calxa Premier 1 Year Subscription and the Calxa Premier 3 Year Subscription. Now login and proceed to the Serial Number step. If you click next on this step it returns the message saying Please fill the Do you have an existing Calxa serial number? field.

Hello,

As described in previous posts I have my fields step as a separate step in the checkout (login_address_shipping_coupon,fields,payment_terms_confirm_cart_status,end). My problem is that you need to click Next twice to proceed to the next step. I assume this has always been an issue since I made the above customisations but I have only just noticed it. Perhaps it is only an issue because the Fields step is on it's own but I do require this to be a separate step.

If you do click past this step to the payment step and then go back you no longer require to click next twice, so I assume the fields are not being marked as OK early enough to proceed the first time.

Can you please assist me with this as I would like the user to be able to fill out the fields and then proceed without having to click next twice?
