i am trying to populate two form fields from data that is retrieved from a database, in order for the user to update them. The table is called records and it is quite simple:
Record_ID
title
content
My model:
function get_data()
{
$r = $this->uri->segment(3);
$query = $this->db->get_where('records', array('Record_ID' => $r));
return $query->result();
}
My controller:
function set_values()
{
$data = $this->entries_model->get_data();
$this->load->view('update_view', $data);
}
and my update record view:
<?php
echo form_open('site/update',$data);?>
Title:
<?php echo form_input('title',set_value('title'));?>
Content:
<?php echo form_input('content',set_value('content'));
echo form_submit('submit', 'Submit');?>
<?php echo form_close();?>
The problem is that i get the following error:
A PHP Error was encountered
Severity: Notice
Message: Undefined variable: data
Filename: views/update_view.php
Line Number: 10
My question is twofold:
- How do i access this data in my view form and
- how do i populate the respective fields with it.
I am new to Codeigniter, my questions may look simplistic but any help would be appreciated. Thanks in advance.

There are a few things going on here:\n\n\n$data is an array or object that is passed to a view. It's ELEMENTS are then available as variables in the view. So, $data['myelement'] = 'somevalue' in the controller would be accessed as $somevalue in the view.\nIf you pass a 2nd parameter to the form_open() method, it is expected to be a key/value pair of attributes for the tag that will be generated. like, array('class' => 'form_class', 'id' => 'form_id')\nIf you want to set the values of your form inputs, use the view helper function set_value(). In your case, use the controller to set elements in the $data array you'll pass to the view. $data['form_values'] = array('title' => $title, 'content' => $content);\n\n\nThen, in the view:",

You should pass a array to your view file. So replace:\n\n$data = $this->entries_model->get_data();\n\n\nwith:\n\n$data['entries_data'] = $this->entries_model->get_data();\n\n\nand on your view file replace:\n\necho form_open('site/update',$data);?>\n\n\nwith:\n\necho form_open('site/update',$entries_data);?>\n",

first you need to pass data in proper way \n\nreplace\n\n$data = $this->entries_model->get_data();\n\nwith:\n\n$data['data'] = $this->entries_model->get_data();\n\n\nfor setting value in set_value you need to do the in-line condition check to check either data is an object or not if object then put value other wise just empty\n\n<?php echo form_input('title',set_value((is_object($data)?$data->title:'')));?>\n\n\nyou have to do the same thing for your all form fields ",
