Submitting checkbox data from a front-end form for a 'Categories' Field Type

Question

I have read a few docs about front-end forms such as the Checkbox field docs.

Although that doc doesn't seem to give an example of what I need.

I have a 'categories' field type. I am creating a front-end form that will need to submit what is checked to the entry. I have tried a few different ways and can't get it to work. This is the last code I tried:

<label for="designTags">Design Tags</label>

{% set categories = craft.categories.group('designs') %}

{% for category in categories %}
    <input type="checkbox" id="designTags" name="fields[designsTags][]" value=" {{ category.id }}"> {{ category.title }} </input> <br />
{% endfor %}

I also tried changing category.title to category.id, but no luck with that either.

And before that, I tried something similar to the code at the bottom of this page (using the option.value) and it still wouldn't work.

Any help you can give is greatly appreciated! :)

Answer 1

I just tried your code and it worked.

Is your entry getting saved at all? If not I assume there might be another error. Add this to your code to output all form errors:

{% if entry is defined %}
    {{ dump(entry.getErrors()) }}
{% endif %}

Although it didn't made a difference in my test, you should remove the space to be sure:

value="{{ category.id }}"

Answer 2

I just wanted to let you know that I figured this out. I had the section handle in craft.categories.group instead of the category handle. I had just gone through everything again to make sure things were matching up and that's when I found it. Some of my category / section / field names were too similar to each other so too easy to swap out. I just made some tweaks to that to prevent this in the future. Thank you for all of the help and suggestions. So glad that's out of the way and figured out. :)

Thanks!
