我的Codeigniter视图中的未定义变量

Question

Having trouble with displaying my data from controller in View.

Searched for this, tried few things and still not working for me.

My controller:

public function microBitcoin()
{
    $arr = array('hashtag' => 'myhashtag', 'tweet_id' => '673899616799191040');
    $data = array();
    $data['liczba_tweetow'] = $this->load->library('Twetterclass', $arr);

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

My View:

 <?php print_r($data); ?>

 <?php echo $data['$liczba_tweetow']; ?>
 //tried with $data->liczba_tweetow;

I still get the same error:

A PHP Error was encountered

Severity: Notice

Message: Undefined variable: data

Filename: views/micro_btc.php

How I can display this variable in my View?

Answer 1

You have to use like this,

print_r($liczba_tweetow);

see this for more information

Answer 2

 <?php echo $liczba_tweetow; 
       print_r($liczba_tweetow);
  ?>

This is proper way to get data in view.

Reference

Answer 3

your view should be look like this

<?php
 print_r($liczba_tweetow); 
?>

instead

<?php print_r($data); ?>

 <?php echo $data['$liczba_tweetow']; ?>
 //tried with $data->liczba_tweetow;**strong text**

when we load a view with the data the it would we converted in variable in respective key so you would get "$liczba_tweetow" instead $data['$liczba_tweetow']

Answer 4

please follow this,in controller

public function microBitcoin()
{
$data['first'] = 'this is first';
$data['second'] = 'this is second';
$this->load->view('micro_btc', $data);
}

In view ,you can catch as like

echo $first;
//it will print this is first
echo $second;
//it will print this is second
