set_value and populating a form with values from the database - El Forum - 01-15-2009

Hi everyone!
I've been working on this issue for a few days and I have no clue what I might have doing wrong.
I need to re-populate a form with values from the database, so what I'm doing in my controller is:
Code:
$this->form_validation->set_rules('spo_address1', lang('sponsor_form_address1'), 'trim|required|xss_clean');
$this->form_validation->set_rules('spo_address2', lang('sponsor_form_address2'), 'trim|xss_clean');
if ($this->form_validation->run() == FALSE) {
// User Clicked on Change Data button
if ($this->input->post('btn_change')) {
$id_sponsor = $this->input->post('id_sponsor');
// Get returns an array ($resultset->row_array())
$sponsor_data = $this->sponsor_model->get(array('id_sponsor' => $id_sponsor));
foreach($sponsor_data as $k => $v) $template[$k] = $v;
}
$this->load->view('sponsor/apply_step1', $template);
}
else {
// Post Sponsor Info
}That code, is for my controller, and in my view file I have:
Code:
<?= form_input('spo_address1', set_value('spo_address1', isset($spo_address1) ? $spo_address1 : '')); ?>
<?= form_input('spo_address2', set_value('spo_address2', isset($spo_address2) ? $spo_address2 : '')); ?>Result: both input boxes are empty when I load the page (the variables are set and they both have values in it).
I checked the set_value function in the Form_validation library, and I saw that the default value is returned only if the field name is not set in the _field_data array (which is built, if I'm correct, when the rules are set), and since I did set them, then the postdata is returned (which I don't have any since I'm loading them from DB).
Changing the line 732 in Form_validation.php file from:
Code:
if ( ! isset($this->_field_data[$field]))Code:
if ( ! isset($this->_field_data[$field]['postdata']))Can someone here point me out in the right direction?
Thanks everybody!

hey w3bm!
I found out what the problem is a few hours ago, it turns out that the rules are set if there are data in the $_POST var, if there is none which is the most common scenario (since most of the time you click a link to go to an edit page), the rules are not set and the set_value function works (since the fields are not set in the form_validation library).
Problem is, I'm not going to the edit page through a link, I'm using a submit button, means the $_POST var is not empty, rules are set, fields are set, set_value doesn't work because it tries to return the postdata value (which is empty).
I'm not sure if this is a bug or is an "error of logic" on my end...
