Each organization's needs vary, and as such some want to track their sales for individual participants within the group and some do not. So instead of creating 30 different products for each participant within the organization, I've created a custom field on the order table for the name of the participant. Now this works great, but only if every organization wants to keep track of which participant a sale is to benefit. But not all of them do. I've created a custom field, Required_Participant_Name, on the product table which is a simple yes/no radio button. Based on the value of the radio button, I would like to display the custom field on the order table for the name of the participant. Is this possible? Is there a more elegant solution to my problem? Any feedback would be greatly appreciated.

There is no option for that but you can do it with a few lines of code customization in the file "fields" of the view "checkout" via the menu Display->Views if you know programming. You will have to loop through the products and based on the value of that field, display or not the custom order fields.

However, if the fields are not shown and the user proceeds to the next checkout step an error is thrown asking the user to fill in the custom field even though it is not displayed. Is there a way to disable this error message as well?? If you want to see the errors I can provide you w/ URL's. Thanks again!

Then in the e-mails, edit where the custom field is printed to only display if not equal to "none". The only problem is I am not entirely sure how to reference the custom field array to set the value of 'participant name' to "none".

You will also have to change the file administrator/components/com_hikashop/classes/field.php so that the check, server side is skipped.

Removing that code seems to have fixed the error message when the custom field is not displayed in FireFox. But if the field is displayed you are still able to proceed to the next step without entering any value into the required custom field. I can see the following in the page source Code: <!-- hikashop['reqFieldsComp']['order'] = Array('participant_name'); hikashop['validFieldsComp']['order'] = Array('Please enter the name of the participant that you are supporting by making this purchase: '); //--> so it is establishing that it is a required field, but the check is not functioning properly.

For those that are interested in what the final steps are for this problem here's a breakdown: 1. Create a custom radio button field on the product table. Label it something like 'Required_Participant_Name'. I've set two values, (title)Yes = (value)TRUE, (title)No = (value)FALSE. 2. Create a custom text field on the order table. Label this one something like 'Participant_Name'. 3. Go to Display->Views modify checkout/fields.php with the following code: Code: <?php /** * @package HikaShop for Joomla! * @version 1.5.5 * @author hikashop.com * @copyright (C) 2010-2011 HIKARI SOFTWARE. All rights reserved. * @license GNU/GPLv3 http://www.gnu.org/licenses/gpl-3.0.html */ defined('_JEXEC') or die('Restricted access'); ?> <?php $cartClass = hikashop_get('class.cart'); $cart = $cartClass->loadFullCart(true); $this->rows =& $cart->products; $required_participant_name = false; foreach($this->rows as $row){ $productClass = hikashop_get('class.product'); $product = $productClass->get($row->product_id); if($product->required_participant_name == "TRUE" ) $required_participant_name = true; } if(!$required_participant_name){ $doc =& JFactory::getDocument(); $js="hikashop['reqFieldsComp']['order'] = Array();"; $doc->addScriptDeclaration( "<!--\n".$js."\n//-->\n" ); return; } ?> <?php if(hikashop_level(2) && !empty($this->extraFields['order']) && $required_participant_name == true){ ?> <div id="hikashop_checkout_additional_info" class="hikashop_checkout_additional_info"> <fieldset class="input"> <legend><?php echo JText::_('ADDITIONAL_INFORMATION');?></legend> <table cellpadding="0" cellspacing="0" border="0" class="hikashop_contentpane"> <?php if(!empty($this->extraFields['order'])){ JRequest::setVar('hikashop_check_order',1); $this->setLayout('custom_fields'); $this->type = 'order'; echo $this->loadTemplate(); } ?> </table> </fieldset> </div> <div style="clear:both"></div> <?php } ?> 4. Find the following file, administrator/components/com_hikashop/classes/field.php. Once located, find the following line of code and comment it out. (Or delete it if you so choose) Code: if(!$class->check($fields[$k],$val,@$oldData->$namekey)){ $ok = false; } This removes the server side form validation. 5. Bada Boom, Bada Bing - You've now got conditional custom fields. Enjoy! Nicolas, thanks again! Last edit: 14 years 7 months ago by [usafadmin](/forum/user/4912-usafadmin "View usafadmin's Profile").

No need to change any code.
