Undefined variable in my Codeigniter View

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?

print_r($liczba_tweetow);

When I use print_r($liczba_tweetow); its printing all my CI_Loader Objects. When I just echo variable echo $liczba_tweetow; I get Severity: 4096 Message: Object of class CI_Loader could not be converted to string Filename: views/micro_btc.php

you are assigning here $data['liczba_tweetow'] = $this->load->library('Twetterclass', $arr);, so you are getting that.

So what I supposted to do to display this data in View?

Niranjan N Raju Over a year ago

you are loading the library to variable, so its printing what ever is returned from library.

My library supposted to return only a single intiger. When I use print_r I get all of CI_Loader Objects. My library Twetterclass is working very well without framework, so I why I just can't get in return what I supposted to get? I get the error: Severity: 4096 Message: Object of class CI_Loader could not be converted to string Filename.

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

This is proper way to get data in view.

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']

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
