I was trying to use FCKEditor in one field on a form, and wanted the form to submit to the controller via AJAX, which would respond with an RJS call to update the page. However, I found that when I clicked "Submit", the FCK field in params was blank, BUT if I clicked submit TWICE in a row, the second one sent all the correct data. Apparently, there's a similar problem with ASP.Net and using the RequiredFieldValidator, so all my searches kept leading me to answers to THAT problem, but I ain't using ASP or RequiredFieldValidator.

Eventually, I finally stopped and actually read all of the listings on the FCKEditor Wiki Troubleshooting page and found this post, which exactly described the problem. However, I'm not a big fan of ridiculously vague code with names like MyClass and MyObject... that's just not the Rails way. So... here's my variation on a theme.

First, Add this to your application.js...

var FCKFixer = {
  fixIt: function() {
    for ( i = 0; i < parent.frames.length; ++i )
      if ( parent.frames[i].FCK )
        parent.frames[i].FCK.UpdateLinkedField();
  }
}

Then add :onclick => "FCKFixer.fixIt();" as an argument to your submit tag. So, now your entire form should look something like...

<% remote_form_for :comment, @comment, :url => post_comments_path(@post) do |f| %>
    <%= f.date_select :birthday %>
    <%= f.select :flag, [['You Rock',:rocks],["You're Great",:great],['Can I Have Your Babies?',:have_babies_request]] %>
    <%= fckeditor_textarea :comment, :body %>
    <%= submit_tag 'Submit', :onclick => "FCKFixer.fixIt();" %>
<% end %>

That's it? Yes! Really? Yes! Have a nice day and see you next time.
