How to specify a condition where all line items must have a (the same) term???

I've added an new quantity field to commerce_order. This field is the total quantity of products of the commerce_order.
So now, you can create a condition Total quantity of selected products comparaison and choose commerce-order:commerce-order-quantity in the data selector as quantity comparaison (quantity field).

Does this work for you ?

Have you flushed cache ?

Below Quantity field, you must have "switch to data selection" button.When clicking, data selector must appear. Select commerce-order. You should see like attachment.
Select commerce-order-quantity.

This means that condition will be fired if total quantity of selected items (by terms and/or content-type) is equal to total quantity of order, in order term, that all products have terms and/or content-type.

Is that what you want ?

Bizarre.
Can you have a look to commerce_rules_extra/commerce_rules_extra.rules.inc and search for commerce_rules_extra_entity_property_info_alter() method (bottom of file).
If found, can you retry to clear cache (registry cache).
If this does'nt work, can you add in commerce_rules_extra_entity_property_info_alter() method this line just after function declaration

drupal_set_message("commerce_rules_extra_entity_property_info_alter() is triggered");

Clear the cache again, message must be printed.

Can you replace

function commerce_rules_extra_entity_property_info_alter(&$info) {
    $info['commerce_order']['properties']['commerce_order_quantity'] = array(
            'type' => 'integer',
            'label' => t('Total quantity'),
            'description' => t('Total quantity of the order.'),
            'getter callback' => 'commerce_rules_extra_get_quantity_property',
            'computed' => TRUE,
    );
}

by

function commerce_rules_extra_entity_property_info_alter(&$info) {
    drupal_set_message("commerce_rules_extra_entity_property_info_alter() is triggered");
    $info['commerce_order']['properties']['commerce_order_quantity'] = array(
            'type' => 'integer',
            'label' => t('Total quantity'),
            'description' => t('Total quantity of the order.'),
            'getter callback' => 'commerce_rules_extra_get_quantity_property',
            'computed' => TRUE,
    );
}

in commerce_rules_extra.rules.inc.
Clear cache and see if the message is printed. This is to be sure hook is done, so you should have commerce-order-quantity field in data selector.

I don't think this is a rule configuration problem.
Have you seen message when you have cleared the cache ?
Yes, access to your site can be useful.

OK. Commit this to dev version and wait for your procedure to close issue

yes, they are debug messages. Install official dev version, messages should be removed.

You're right. Commited to dev.
Sorry for the inconvenience

As described at https://drupal.org/node/2059325#comment-7900965, term comparison rules has been modified.
A new field, operator (like in your screenshot) allows you to select one of these values (is one of, is all of, is none of, is empty, is not empty).
For your needs, can you try selecting is all of ?

I'm confused about broken rules due to new features. I will try to release a version soon to prevent inconveniences.

I am having this issue too. Can't find the "commerce-order:commerce-order-quantity" data selector, no matter what I do. I have looked at the code and it appears to be moved to the .module file, out of the .inc. One thing I'm not clear on is what event type this condition happens on. I'm assuming "Process checkout pane"?

I'm using 7.x-2.0-alpha3, should I be using the dev version? MrPaulDriver, if you would be so kind as to post your write-up you mentioned in #16? :)

Also, I'm using Kickstart 2.6. Has there ever been a reported problem with this module and KS?

To be sure, can you try with dev version ?
Don't forget to flush caches.

Thanks for the quick reply Marc. I tried the dev version and still same problem. Interesting though is that Drush was confused, even though I specified the dev version it wanted to do the alpha, so I did it manually.

Can you please confirm that the event type should be "Process checkout pane"?

Field is available for any event using commerce_order but only for data comparison condition.

To be more precise, field is also avalaible in QUANTITY data selector for Total quantity of selected product comparison or Total product quantity comparison

Still not seeing it. What am I doing wrong?

Which condition do you use ?

Total quantity of selected product comparison. All I'm trying to do is calculate FedEx shipping rates based on a taxonomy term.

For this condition, you do not need quantity field.
Select term and set quantity and operator (for example > 1).
For this example, if total quantity of products with specified term (calculated by the rule) is greater than 1 , action can be ran.

Quantity field could be selected in Data comparaison condition

So sorry, I was totally looking for it in the wrong place. There is an ORDER data selector, and a QUANTITY one where I did find commerce-order:commerce-order-quantity. Reading back through this thread, it now makes much sense and realize that I didn't need it after all. MrPaulDriver's use case was not the same as mine.

So I have the rule firing correctly and the FedEx or Flat rate (free) is working on the proper terms of a product. However, if I have one product in the cart that gets the FedEx rate and another that gets the free rate, the rates that FedEx come back with are based on both items. Not sure whether this is a rule issue or a FedEx module one, any insights?

I don't know shipping rates, but i suppose you code your rule like (if order contains a product for xxx term then apply fedex rate).
So you will apply rate to all products if only one product is for tem xxx.
If you want to test if ALL products are for term xxx, you could choose equal operator and quantity field in QUANTITY data selector so rule will be fired only if number of products of term x is equal to total quantity of order.
I close this issue because this is a rule conception problem.
