Drupal 7 – Increase the number of values per field

A long time ago, i have a post about hacking into the CCK module so we could have more options when settings the number of values per field in the field setting page.
Drupal – Increase Views Relationship Delta Limit

This is a dirty approach as mentioned by eosrei.

So in Drupal 7, we can do it by creating a custom module and alter the field_ui_field_edit_form. Let’s implement the following hook_form_FORM_ID_alter() in a custom module.

function <module>_form_field_ui_field_edit_form_alter(&$form, &$form_state, $form_id) {
  // Increase the max cardinality to 20
  $range = drupal_map_assoc(range(1, 20));
  $new_options =  array(FIELD_CARDINALITY_UNLIMITED => t('Unlimited')) + $range;

  // Change the options
  $form['field']['cardinality']['#options'] = $new_options;


Go to the field setting page and now we can set the limit up to 20.

Done =)

  1. This appears to work for adding 11-20 to the fields. For whatever reason though it in not increasing the Delta limit beyond 10 in any of the relationships pages from within Views (even after I set the field for the relationship to a max number of 20). Is there something I’m missing? Thanks for your help!


      1. Ykyuen, Thank you so much for getting back to me. I apologize, I hadn’t realized you responded. I set the field = to 20 inside of a field collection. Then when I go to the relationship page in the view my option is any or (1-10) ideally what I need to do is be able to select delta 11 – 20 in the relationship selector in order to display the item in the 11th instance of the particular field in the field collection. I can send pictures if you think it will help. Thanks!



  2. Any thoughts on this Ykyuen? I’ve been at it for a day or two now and haven’t come up with a solution. I’d really appreciate any help you can provide. If you need additional information from me please just let me know.



    1. I have created a content type called Person and has a field collection called Item which is a field collection. The Item only has a multiple field called item name

        - Item (field collection)
          - item name (a multiple field which has 20 cardinality)


      So next i created a new view called People which select all the Person content. I added the Item field collection relationship.

      Then add the item name field and set the multiple field settings such that it will start from the 11th item name.

      Is that what u want?


  3. Hi,

    I have a select list field called “Number of installments” (1 to 20) on my custom content type.

    I also have a field collection item called “Installments” (Having date, note, amount fields in it)

    I want to dynamically add “Installments” based on the value of “Number of installments”.

    I want this to avoid clicking “add more” multiple times.

    Is it possible?

    Thank you very much.
