I'm using form_set_error to display the error messages if there is no product.

My Issue is:

For example, I am having 3 products in the checkout page.

When I clicks submit I need to validate that all the products are available.

Here, let us consider if the second product is not available I am showing the error message "Product Stroke 2 is not available".

But all the check boxes in the cart is highlighted

Because I had set form_set_error to items element.

How can I set form_set_error for every individual element.

What I have given to display error message:enter image description here

form_set_error('items', 'Not available');

Kindly guide me how to resolve the issue. I am using ubercart module with drupal 6.

There is a comment on the API page for form_set_error which explains how to set a form error on a subelement of a form item.

From the comment: 

form_set_error('field_name][i][value', t('Your message'));

  • I didn't downvote, but just posting links isn't a good answer. From drupal.stackexchange.com/questions/how-to-answer, "A link to a potential solution is always welcome, but please add context around the link so your fellow users will have some idea what it is and why it’s there . Always quote the most relevant part of an important link, in case the target site is unreachable or goes permanently offline." – mpdonadio♦ Mar 22 '12 at 10:36
  • Well, I can understand this policy, but when api.d.o will go offline, all this site will be useless anyway. I'll try to complete my answer, though. – Countzero Mar 22 '12 at 11:02
  • +1 for the updated answer according to SOF strategy.. And its working fine... Great : Cheers :) – Fero Mar 23 '12 at 7:24
