hi yousuf, i think you have problem in your foreach loop try to print out array in view with print_r If it contains result.
I think you have empty array in foreach..

Hi Yusuf,

Please try debug it using print_r . Step by step

CONTROLLER

class Main extends Controller{

function index(){
$this->load->helper('form');
$this->load->view('profile');
}

function createProfile(){
$this->load->helper('url');
//if ($this->input->post('name')){
$this->load->model('Mprofile','',TRUE);
$this->Mprofile->addData();
redirect('main/myResult','refresh');
//}
//else{
// redirect('main/createProfile','refresh');
//}
}

function myResult(){
$this->load->helper('url');
$this->load->model('Mprofile', '', true);
$data['result'] = $this->Mprofile->getData();

Please try print_r in here then exit, to know if is there any data result.

print_r($data['result']);exit();

If any array result than try print_r in views

$data['page_title']="Yousuf";
$this->load->view('viewentry',$data);
}
}
?>

VIEW-2
<html>
<head>
<title><?=$page_title?></title>
</head>
<body>

please try print_r the result, is there any result data ?
print_r($result);exit();

<?php foreach($result as $row):?>
<h3><?=$row->name?></h3>
<p><?=$row->address?></p>
<h3><?=$row->phonenumber?></h3>
<p><?=$row->email?></p>
<h3><?=$row->occupation?></h3>
<p><?=$row->interests?></p>
<h3><?=$row->filename?></h3>

<br />
<?php endforeach;?>
</body>
</html>[/quote]

fyi, a nice way to handle forms is to name each of the fields by array vs individually, so instead of

<input name="name" type="text">
<input name="email" type="text">
<input name="address" type="text">

and having to use $this->input->post() on each, you use

<input name="form[name]" type="text">
<input name="form[email]" type="text">
<input name="form[address]" type="text">

and in your controller use $this->input->post('form'); It will contain the entire array from the form and can be validated easliy and sent directly to the model. For model forms typically i use this and name the form according to model, ie $user_data = $this->input->post('user',TRUE);

glad you got it to work tho
