Get data from html form to ruby in Ruby on Rails
Get data from html form to ruby in Ruby on Rails
I have some html like this
<html>
<h1>Tex开发者_如何学编程t to PDF</h1>
<textarea name="comments" cols="40" rows="5">
Enter your Text here...
</textarea><br>
<input type="submit" value="Submit" />
</form>
</body>
</html>
I want to give the value of the text into the controller for this page/view. How do I do this with rails?
I am new to rails, what is the mechanism for this? I don't need to write to the database just want to hand it to the controller. If there is a good tutorial for this sort of thing that would be great, I am not convince I am approaching this correctly.
You can use params['comments'] in your controller to get the value.
In your controller-
def parse_comments
comments_from_form = params['myform']['comments']
#do your stuff with comments_from_form here
end
In your view-
<h1>Text to PDF </h1>
<%= form_tag :action => 'parse_comments' do %>
<%= text_area :myform, :comments, :cols => '40', :rows => '5' %>
<%= submit_tag "Submit" %>
<% end %>
(edit: added = to form_tag opening, without it code won't work)
