CodeIgniter将数据传递给视图

Question

I am trying to pass from my controller to the view like so...

public function playerslist()
    {
        $this->load->database();
        $data = $this->db->get('skaters');
        $this->load->helper('url');
        $this->load->view('playerslist', $data);
    }

and in my view...

<?php echo $data; ?>

but I get this error...

A PHP Error was encountered

Severity: Notice

Message: Undefined variable: data

Filename: views/playerslist.php

Line Number: 76

What am I doing wrong?

What I would like to do with this data is put in a foreach statement and display everything in the $data array

foreach($data as $value => $key){
echo $key . "<br/>";
}

Thanks, J

You cannot access $data directly from your view. The $data you pass to your view has to be an associative array. The keys will then be converted to variables in your view.

For example:

$data = array(
    'name' => 'John',
    'bars' => 23
);

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

Then, in your view, those will be converted to variables:

<?php echo $name; ?> has <?php echo $bars; ?> bars of chocolate.

If you want to access the data in its original format, pass that into the associative array:

$data = $this->db->get('skaters')->result();
$this->load->view( 'playerslist', array('data' => $data) );
