In my model I have this snippet
$this->db->select('*');
$this->db->from('User');
$this->db->where('email', $mail);
$query = $this->db->get();
return $query;
As far as I know, $query is an array (a set of results), I want to retrieve an specific value of a field in that array to return it or to assign it to another variable, the question is HOW?
I'd like to do something like this
$value = $query['first_field_of_resultset'];
return $value;
extending Johns answer, you need to cover yourself in case nothing comes back so in your model method:
// make sure we have a result
if ( $query->num_rows() == 1 )
{
// assign the result
$user = $query->row();
// pull out the field you want
$value = $user->first_field_of_resultset;
// return it
return $value ;
}
else { return FALSE; }
Then in your controller, say if the model is called user_model
if(! $value = $this->user_model->getUser($email) )
{
// boo hoo no results
}
else
{
// success
}
And of course this assumes you have run $email through CI form validation to make sure it is a valid email -- before sending to your database.
