Can't update a controller variable in model

You're close, but you must return your new vendor id from the model like this.

Code:

// controller
$vend_id = $this->m_client->save_vendor();
if($vend_id !== true){
   // not returning true, so must be a new vendor id from model, update our controller vendor_id
   $this->vendor_id = $vend_id;
}

Code:

//model
...
if($this->vendor_id)
   {
     $this->db->where('vendor_id',$this->vendor_id);
     $this->db->update('vendor',$vendor_data);
     return true
   }else{
     $this->db->insert('vendor',$vendor_data);
     return $this->db->insert_id();
   }

You cant just access variables set in a model direct from your controller, you must pass them back (otherwise you'd run the risk of "over riding" your controller variables from your model if you mistakenly called them both the same thing).
