Question

I am using Codeigniter message library.

In my controller I have the following code

public function __construct() {
    parent::__construct();
    $this->load->library('message');  
}

public function box($box_id=null, $language_name=null) {
   if($id_from_url[5]==null){
      $this->message->set('Please provide Box ID in URL.', 'error');
    }
}

In my view I use

    $this->message->display(); 

I have already put Message.php in my application/libraries folder
but I am getting the following error

Message: Missing argument 1 for CI_Message::CI_Message(), called in W:\Zend\Apache2\htdocs\mediabox\system\core\Loader.php on line 1099 and defined

Any idea about this error ?

Thanks in advance

Answer 1

Your title is completely different than the error you are getting here. It clearly states that the Message library requires a parameter passed to its construct, but you are loading the library without any construct parameters.

You need to pass the construct parameters using the second parameter while loading it

$this->load->library('message',$config);

If you are actually talking about this Message library here http://codeigniter.com/wiki/Message then I must say, the documentation there is incomplete.

function CI_Message($config){    
    $this->CI =& get_instance();        
    $this->CI->load->library('session');

    if($this->CI->session->flashdata('_messages')) $this->messages = $this->CI->session->flashdata('_messages');
    if(isset($config['wrapper'])) $this->wrapper = $config['wrapper'];
}

The construct here requires a parameter $config passed to it.

Check the documentation thoroughly. You need to pass this while loading it.

$config = array();
$config['wrapper'] = array('<div id="messages">', '</div>'); 

then

$this->load->library('message',$config);
