Codeigniter Update doesn't work - php

Question

i'm having trouble getting my update to work. delete, view and add work fine.
this is my extraoptie_model:
function update($id, $extraOptie) {
$this->db->where('id', $id);
$this->db->update('extraOptie', $extraOptie);
}
my controller:
function update($id) {
// Check admin if not Acces Denied
$gebruiker = $this->session->userdata('gebruiker');
if ($gebruiker->accountLevel != "admin") {
$data['title'] = 'Acces Denied';
$partials = array('header' => 'main_header', 'content' => 'admin_noacces', 'footer' => 'main_footer');
$this->template->load('main_master', $partials, $data);
} else {
// prefill form values
$extraOptie = $this->extraoptie_model->get($id);
$data['id'] = $id;
$data['beschrijving'] = $extraOptie->beschrijving;
$data['actuelePrijs'] = $extraOptie->actuelePrijs;
$data['soort'] = $extraOptie->soort;
$data['aantalGangen'] = $extraOptie->aantalGangen;
$data['tabelNaam'] = $extraOptie->tabelNaam;
// set common properties
$data['title'] = 'Extra optie update';
$data['message'] = '';
$data['action'] = site_url('admin/extraoptie/updateExtraOptie/');
// load view
$partials = array('header' => 'main_header', 'content' => 'admin_extraoptieedit', 'footer' => 'main_footer');
$this->template->load('main_master', $partials, $data);
}
}
function updateExtraOptie() {
// Check admin if not Acces Denied
$gebruiker = $this->session->userdata('gebruiker');
if ($gebruiker->accountLevel != "admin") {
$data['title'] = 'Acces Denied';
$partials = array('header' => 'main_header', 'content' => 'admin_noacces', 'footer' => 'main_footer');
$this->template->load('main_master', $partials, $data);
} else {
// set common properties
$data['title'] = 'Update extra optie';
$data['action'] = site_url('admin/extraoptie/updateExtraOptie');
// save data
$id = $this->input->post('id');
$extraOptie = array('beschrijving' => $this->input->post('beschrijving'),
'actuelePrijs' => $this->input->post('actuelePrijs'),
'soort' => $this->input->post('soort'),
'aantalGangen' => $this->input->post('aantalGangen'),
'tabelNaam' => $this->input->post('tabelNaam'));
if ($extraOptie['aantalGangen'] == '') {
$extraOptie['aantalGangen'] = null;
}
if ($extraOptie['tabelNaam'] == '') {
$extraOptie['tabelNaam'] = null;
}
$this->extraoptie_model->update($id, $extraOptie);
// set user message
$data['message'] = '<div class="success">update success</div>';
// redirect to index
redirect('admin/extraoptie/index', 'refresh');
}
}
my view:
<table class='centered text'>
<form method="post" action="<?php echo $action; ?>">
<?php
$hidden = array('id' => $id);
form_hidden($hidden);
?>
<tr>
<td><?php echo form_label('Beschrijving:', 'beschrijving'); ?></td>
<td><?php echo form_textarea(array('name' => 'beschrijving', 'id' => 'beschrijving', 'value' => $beschrijving, 'cols' => '30', 'rows' => '5')); ?></td>
</tr>
<tr>
<td><?php echo form_label('Prijs:', 'prijs'); ?></td>
<td><?php echo form_input(array('name' => 'actuelePrijs', 'id' => 'actuelePrijs', 'value' => $actuelePrijs, 'size' => '10')); ?></td>
</tr>
<tr>
<td><?php echo form_label('Soort:', 'soort'); ?></td>
<td><?php echo form_input(array('name' => 'soort', 'id' => 'soort', 'value' => $soort, 'size' => '30')); ?></td>

<td colspan='2' class='center'>
<?php echo form_submit('submit', 'Opslaan', 'id="opslaan"');; ?>
<?php echo form_button('annuleer', 'Annuleren', 'id="annuleer"'); ?>
<?php form_close(); ?>
</td>
</tr>

All help is welcome have been working on it for couple of hours and can't seem to find the problem.

Answer 1

possibly the issue arises from the fact that
you have a php form_close();
but do not have a php form_open();
not sure offhand how CI would react to a close without an open.

Answer 2

Do you have CSRF protection enabled? If so, you will need to either use form_open(), as steve has said, or add a hidden input with your csrf token such as:
<input type="hidden" name="<?php echo $this->security->get_csrf_hash();?>" value="<?php echo $this->security->get_csrf_token_name();?>"/>

Answer 3

Thank you both for your quick response!
I have found the error after staring at the code for another couple of hours together w/ a friend.
the problem was i didn't echo form_hidden($hidden) so no id was passed through to the update model.
<table class='centered text'>
<form method="post" action="<?php echo $action; ?>">
<?php
$hidden = array('id' => $id);
form_hidden($hidden);
?>
<tr>
so it had to be:
<table class='centered text'>
<form method="post" action="<?php echo $action; ?>">
<?php
$hidden = array('id' => $id);
echo form_hidden($hidden);
?>
