        $config['max_width']  = '1024';

}
$public;
if($share_with=="public"){
    echo "1";
    $public=true;
}else{
    echo "0";
    $public=false;
}echo "-----------------------------<br/>";
echo $user=$this->session->userdata('user_identification');
$data = array 
        (
            'userid'=> $user,
            'public' => $public,
            'message' => $post_message,
            'picname' => "None"
        );
$this->load->model('membership_model');
$this->membership_model->add_message($data);
echo "</br>";
echo $user=$this->session->userdata('user_identification');
}

I am confused about why the error is happening. Please HELP me.

Answer 1

It will be $_FILES

$image = $_FILES['image'];
print_r($image);

It will return an array so you need to print it.All the files,images which you are upload through the file type they all will be handeled by $_FILES and makesure that your form will be multipart like

<form enctype='multipart/form-data'>
     <input type="file" name="image">
</form>
