通过保存在codeigniter中的配置文件中的名称获取数据库$ row属性

Question

I am trying to go over $row object which I got from the $this->db->get()->result();

The table column names are stored in config file, which I can access like this : $this->tableTask [ 'column' ] [ 'id' ];

How do I do the following in a single command instead of first assigning the column name to a variable then reaching the $row property ?

This works.

$id = $this->tableTask['column']['id'];
$this->data[$this->tableTask[ 'column']['id']] = $row->$id;

This does not. I get the following error.

Error Message: Object of class Task could not be converted to string

$this->data[$this->tableTask['column']['id']] = $row->$this->tableTask['column']['id'];

Note: This all is happening inside a method of class Task which is an auxiliary class to a custom library I am working on.

Try encapsulating your variable like this (notice the "{}" marks):

$this->data[$this->tableTask['column']['id']] = $row->{$this->tableTask['column']['id']};

If you want to use the property value for obtaining the name of another property you have to encapsulate your your value call.
