Im trying to have a form submit to a controller were it is then inserted into a database.  It worked for the past couple days but apparently i accidentally changed something because it "randomly" doesn't work.  Any help would be appreciated as i couldn't figure it out after searching online.  Thanks! 
PHP 
 public function    houses () {
if ($this->input->post()) {
    $bedrooms = $this->input->post('bedrooms');
    $bathrooms = $this->input->post('bathrooms');
    $street = $this->input->post('street');
    $house_number = $this->input->post('house_number');
    $basement = $this->input->post('basement');
    $garage = $this->input->post('garage');
    $fence = $this->input->post('fence');

    $query = $this->db->query('INSERT INTO houses VALUES (NULL, "'. 
         $bedrooms. '","'.$bathrooms. '","'.$house_number.'","'. 
         $street. '","'.$basement. '","'.$garage. '","'.$fence.'")'); 
}

$query = $this->db->query("SELECT * FROM houses");

foreach($query->result() as $row) {
    $data['bedrooms'] = $row->bedrooms; $data['bathrooms'] = $row->bathrooms;
    $data['house_number'] = $row->house_number;
    $data['street'] = $row->street; $data['garage'] = $row->garage;
    $data['basement'] = $row->basement; $data['fence'] = $row->fence;
    $data['id'] = $row->id;

    $this->data['houses'][] = $data;
}

$title = 'Houses';
$this->data['title'] = $title;
$this->template->add_css('css/dog.css');
$this->template->write_view('content', 'houses', $this->data);
$this->template->render();
 }

HTML 
<form method='post' action='<?php site_url('welcome/houses')? >'>
  <li><span>Bedrooms</span>
    <input type="text" name="be stdClass::$emaildrooms" /></li>
  <li><span>Bathrooms</span>

   <select name="garage">

   <select name="fence">
     <option>Yes</option>

   </select><br/>
 </li>
 <input type="submit" name="Submit" />
</form>

A:

Your error is here:
<input type="text" name="be stdClass::$emaildrooms" />

be stdClass::$emaildrooms contains characters that Codeigniter does not allow in input keys. 
It looks like a mistake anyways, as if stdClass::$email snuck in somehow - maybe while you did a massive search/replace in your files.
