set_value() default value issues - El Forum - 07-24-2009

I have a form, and the same view does adds and edits so I'm using this format for my code in the form

Code:
$course_name = array('name' => 'course_name',

            'id' => 'course_name',

            'class' => 'text long',

            'value' => set_value('course_name', $row->course_name));

echo form_input($course_name);

//And in the controller

function add()

{ 

  $data['row'] = array();

  $this->load->view($this->view.'edit', $data);      

}

function edit()

{

  $query = $this->db->get_where($this->tbl, array($this->primary_key => $this->id));

  $data['row'] = $query->row();

  $this->load->view($this->view.'edit', $data);     

}

notice the empty

Code:
$data['row'] = array();

in the add method. I thought this would suppress any erros but im getting

Code:
A PHP Error was encountered

Severity: Notice

Message: Trying to get property of non-object

Someone tell me what im doing wrong?

in add $row is not an object, just a simple variable where as in edit its a database object which has course_name as object variable. in case of add leave the set value blank, where as in edit you can use it

Code:
$course_name = array('name' => 'course_name',

            'id' => 'course_name',

            'class' => 'text long',

            'value' => (is_object($row)?set_value('course_name', $row->course_name):''));

or use object 

$data['row'] = (object) array('course_name'=>'');

hope it will work fine.
