title: Rails 3 Form fields not submitting params
body: <p>I am building an admin section for an app I'm working that lists businesses.  Admins can then go in and submit an email address and activate the business. So I am using a form_tag within a block like so:</p>
  
  <pre><code>&lt;% for business in @businesses %&gt;   
  &lt;tr&gt;
      &lt;td align="center" class="border-table"&gt;&lt;%= business.id %&gt;&lt;/td&gt;
      &lt;td align="center" class="border-table"&gt;&lt;%= business.name %&gt;&lt;/td&gt;
      &lt;td align="center" class="border-table"&gt;&lt;%= business.address %&gt;&lt;/td&gt;
      &lt;td align="center" class="border-table"&gt;&lt;%= business.phone %&gt;&lt;/td&gt;
      &lt;% @user = User.new %&gt;
      &lt;%= form_tag "/businesses/activate?business_id=#{business.id}", :remote =&gt; true, :method =&gt; :put do %&gt;
          &lt;td align="center" class="border-table" id="&lt;%= business.id %&gt;_email"&gt;&lt;%= text_field_tag "email", nil, :placeholder =&gt; "email" %&gt;&lt;/td&gt;
          &lt;td align="center" class="border-table" id="&lt;%= business.id %&gt;_activate"&gt;&lt;%= submit_tag "Activate" %&gt;&lt;/td&gt;
      &lt;% end %&gt;
    &lt;/tr&gt;
  &lt;% end %&gt;
  </code></pre>
  
  <p>So on a given admin page there are 25 of these forms, one for each row in the table.</p>
  
  <p>The problem is, for whatever reason, the "email" param is not getting posted, just the business_id (from the path).</p>
  
  <p>Is there something I am doing wrong? Are you not supposed to generate multiple similar forms using a block?</p>
  
  <p>Any advice would be much appreciated.</p>
  
  <p>Thanks!</p>
