Question

I have such code:

= hidden_field(:user_id, nil, :value => params[:user_id])

But it is generating such html:

<input id="user_id_" name="user_id[]" type="hidden" value="1">

But what i need to write, to generate such html code:

<input id="user_id" name="user_id" type="hidden" value="1">

Without any arrays? Also, if i write only one input, without any form tags, will i see this value in params, or i must to write full: form_tag, then there hidden field?

Answer 1

Use hidden_field_tag

hidden_field_tag 'user_id', 1
# => <input id="user_id" name="user_id" type="hidden" value="1" />
