Overview

Action View Form Tag Helpers

Provides a number of methods for creating form tags that don’t rely on an Active Record object assigned to the template like FormHelper does. Instead, you provide the names and values manually.

NOTE: The HTML options disabled, readonly, and multiple can all be treated as booleans. So specifying disabled: true will give disabled="disabled".

Instance Method Details

#button_tag(content_or_options = nil, options = nil, &block)

Creates a button element that defines a submit button, reset button or a generic button which can be used in JavaScript, for example. You can use the button tag as a regular submit tag but it isn’t supported in legacy browsers. However, the button tag does allow for richer labels such as images and emphasis, so this helper will also accept a block. By default, it will create a button tag with type submit, if type is not given.

Options

:data - This option can be used to add custom data attributes.
:disabled - If true, the user will not be able to use this input.
Any other key creates standard HTML options for the tag.

Examples

button_tag
# => <button name="button" type="submit">Button</button>

button_tag 'Reset', type: 'reset'
# => <button name="button" type="reset">Reset</button>

button_tag 'Button', type: 'button'
# => <button name="button" type="button">Button</button>

button_tag 'Reset', type: 'reset', disabled: true
# => <button name="button" type="reset" disabled="disabled">Reset</button>

button_tag(type: 'button') do
  content_tag(:strong, 'Ask me!')
end
# => <button name="button" type="button">
#     <strong>Ask me!</strong>
#    </button>

# File 'actionview/lib/action_view/helpers/form_tag_helper.rb', line 647


alias_method :fieldset_tag, :field_set_tag

#file_field_tag(name, options = {})

Creates a file upload field. If you are using file uploads then you will also need to set the multipart option for the form tag:

<%= form_tag '/upload', multipart: true do %>
  <label for="file">File to Upload</label> <%= file_field_tag "file" %>
  <%= submit_tag %>
<% end %>

The specified URL will then be passed a ::File object containing the selected file, or if the field was left blank, a StringIO object.

Options

Creates standard HTML attributes for the tag.
:disabled - If set to true, the user will not be able to use this input.
:multiple - If set to true, *in most updated browsers* the user will be allowed to select multiple files.
:accept - If set to one or multiple mime-types, the user will be suggested a filter when choosing a file. You still need to set up model validations.

Examples

file_field_tag 'attachment'
# => <input id="attachment" name="attachment" type="file" />

file_field_tag 'avatar', class: 'profile_input'
# => <input class="profile_input" id="avatar" name="avatar" type="file" />

file_field_tag 'picture', disabled: true
# => <input disabled="disabled" id="picture" name="picture" type="file" />

file_field_tag 'resume', value: '~/resume.doc'
# => <input id="resume" name="resume" type="file" value="~/resume.doc" />

file_field_tag 'user_pic', accept: 'image/png,image/gif,image/jpeg'
# => <input accept="image/png,image/gif,image/jpeg" id="user_pic" name="user_pic" type="file" />

file_field_tag 'file', accept: 'text/html', class: 'upload', value: 'index.html'
# => <input accept="text/html" class="upload" id="file" name="file" type="file" value="index.html" />

#form_tag(url_for_options = {}, options = {}, &block)

Starts a form tag that points the action to a URL configured with url_for_options just like ActionController::Base#url_for. The method for the form defaults to POST.

Options

:multipart - If set to true, the enctype is set to “multipart/form-data”.
:method - The method to use when submitting the form, usually either “get” or “post”. If “patch”, “put”, “delete”, or another verb is used, a hidden input with name _method is added to simulate the verb over post.
:authenticity_token - Authenticity token to use in the form. Use only if you need to pass custom authenticity token string, or to not add authenticity_token field at all (by passing false). Remote forms may omit the embedded authenticity token by setting config.action_view.embed_authenticity_token_in_remote_forms = false. This is helpful when you’re fragment-caching the form. Remote forms get the authenticity token from the meta tag, so embedding is unnecessary unless you support browsers without JavaScript.
:remote - If set to true, will allow the Unobtrusive JavaScript drivers to control the submit behavior. By default this behavior is an ajax submit.
:enforce_utf8 - If set to false, a hidden input with name utf8 is not output.
Any other key creates standard HTML attributes for the tag.

Examples

form_tag('/posts')
# => <form action="/posts" method="post">

form_tag('/posts/1', method: :put)
# => <form action="/posts/1" method="post"> ... <input name="_method" type="hidden" value="put" /> ...

form_tag('/upload', multipart: true)
# => <form action="/upload" method="post" enctype="multipart/form-data">

<%= form_tag('/posts') do -%>
  <div><%= submit_tag 'Save' %></div>
<% end -%>
# => <form action="/posts" method="post"><div><input type="submit" name="commit" value="Save" /></div></form>

<%= form_tag('/posts', remote: true) %>
# => <form action="/posts" method="post" data-remote="true">

form_tag(false, method: :get)

  # Use raw HTML to ensure the value is written as an HTML entity; it
  # needs to be the right character regardless of which encoding the
  # browser infers.

end
