Geting value from front end Joomla form?

I am just learning Joomla here and it seems that I just cant get it, looked though heaps of websites and still nothing. Can someone explain it to me. I have a form on front end component view:

<form method="post" name="adminForm" id="adminForm">
  <div class="btn-group pull-right">    
    <select name="category" id="category" class="input-medium" onchange="document.adminForm.submit()">    
      <option value="10"><?php echo '10 By';?></option>
      <option value="14"><?php echo '14 By';?></option>                 
    </select>
  </div>                
</form>

Now is this format even correct and how do I now get the option value in model of that view? I tried using: 

$category = $mainframe->getUserState( "category", $default_category );

but it seem to not working and I am only getting $default_category value in there.

Any advice or maybe a short example will be much appreciated.

Thank you.

$category = $mainframe->getUserState( "category", $default_category );

This would work only if you have set the user state in the first place.

To get the values from a POSTed form you can use

$jinput = JFactory::getApplication()->input;
$category = $jinput->get('category', $default_category, 'int');

Suggest you read more about JInput here - JInput

Note that in a typical form saving scenario you won't need to separately get request variables using JInput, since the saving is handled by Joomla if you name your tables and form inputs correctly.
