CodeIgniter将模型数据传递给视图[重复]

• Codeigniter: Passing data from controller to view 13 answers

I have a model method which returns time and view to pass the data. But when I pass the data I get Undefined variable error message.

$this->load->model('Driver_model');
$result = $this->Driver_model->get_shift_data($id);

This is the method calling and if I use var_dump($result). I get following result.

array (size=1)
  0 => 
    object(stdClass)[26]
      public 'start_time' => string '2016-01-22 05:32:42' (length=19)

But if I send the $result to the view, I get error.

$this->load->view('driver/report_view.php', $result);

My question is, how it possible to work in controller if I don't load the view. But if I send the data, it doesn't identify the variable.

A PHP Error was encountered

Severity: Notice

Message: Undefined variable: result

Filename: driver/report_view.php

Line Number: 52

Backtrace:

Function: view

I have tested it using var_dump($result) in view as well.

      <div class="panel-body">
Line 52    <?php var_dump($result); ?>                              
        <form>

</div>

You can not pass a simple variable $result in load view function for view.

You need to create an associative array for sending data to view from controller. You can use as:

$this->load->model('Driver_model'); $data['result'] = $this->Driver_model->get_shift_data($id);

Now send $data array to your view as:

$this->load->view('driver/report_view.php', $data);

Now you can use var_dump() in view file as:

<?php var_dump($result); ?>

Note that if you want to send any other data from controller to view you can follow the same example.

For more explanation see this example:

$data['result'] = 1;
$data['result2'] = 2;
$data['result3'] = 3;

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

In view you can get data as:

echo $result; // 1
echo $result2; // 2
echo $result3; // 3
