getting the value of the single field output using the codeigniter active record

问题

the following function is supposed to read the name of the give asset code from the database. but it triggers the error: "Trying to get property of non-object"

function sban_name($asset){
    $this->db->select('name');
    $this->db->from('asset_types');
    $this->db->where('code',$asset);
    return $this->db->get()->result()->row('name');
}

All I want is to have the name of the asset returned back to the controller! Your help is highly appreciated!

回答1:

Use row() like,

return $this->db->get()->row()->name;

回答2:

Use row() for a single row, and result() for multiple rows.

回答3:

do like this, asset_types is your table name

function sban_name($asset){
    $this->db->select('name');
    $this->db->from('asset_types');
    $this->db->where('code',$asset);
    return $this->db->get('asset_types');
}

And in your controller acess it like

$result=$this->modelname->sban_name('$asset')->row();
$name=$result->name;
