I am very new to codeigniter and I was wondering if someone can help me. I want to pass a variable from my controller to my view, but the way I am do it it always give a undefined variable error. Also, if I keep the load->view call give an error too!
So, how can I pass the variable to the view? Thanks in advance to any help!
<?php <!-- view -->
echo form_open('match/setDefafultEmail', array(
'class' => '',
));
?>
<div class="well">
<div class="text-center">
<h4>Set Default Email</h4>
</div>
<?php
echo("<div>");
echo form_label('Email:');
echo form_input(array(
'id' => 'email_address',
'name' => 'email_address',
'type' => 'email',
'placeholder' => 'email#example.com',
'value' => set_value('email_address'),
'required' => '',
'title' => 'Email address'
));
echo("</div>");
echo("<div>");
echo form_submit(array(
'id' => 'btn',
'name' => 'min',
'type' => 'Submit',
'class' => 'btn btn-info',
'value' => 'Set Default Email'
));
echo("</div>");
echo form_close()
?>
<br>
<br>
<table class="table" >
<thead>
<tr>
<th>Name</th>
<th>Default Email</th>
</tr>
</thead>
<tr class="info">
<!--display current default name and email-->
<?php foreach($info as $row):?>
<td> <?php echo $row->full_name ?> </td>
<td> <?php echo $row->email ?> </td>
<?php endforeach;?>
</tr>
</table>
public function setDefafultEmail(){
$this->load->library('form_validation');
$this->form_validation->set_rules('email_address', 'Email Address', 'valid_email');
if ($this->form_validation->run( ) == true){
$name = $this->input->post('full_name');
$default_email = $this->input->post('email_address');
$this->spw_vm_request_model->setEmailToDefault($name,$default_email);
}
$data['info'] = $this->request_model->getDefaultEmailAndName();
$this->load->view('admin/admin_dashboard',$data);
redirect('admin/admin_dashboard');
}

1) After you load the view you don't need to redirect. When you redirect('admin/admin_dashboard') you actually call the admin_dashboard Controller.
2) On your View you are trying to access an array as an object( $row->full_name ) I think you should use $row['full_name'].
3) In case your Model returns an object, you have to serialize it in your Controller and unserialize it in your View.
