update product details not working CodeIgniter - php

Question

I'm making a fuction on the CodeIgniter framework so users are able to edit/update product detail information. But when I submit the form I get a blank page and the product isn't updated in my database. I couldn't find a mistake myself.
Here is my view file form (cadeaubewerken.php):
<table class="aanbieding-cadeau">
<form action="<?php echo base_url() . "KdGwController/update_product"; ?>" method="post">
<tr>
<h4>Cadeau naam</h4>
<td><?php echo form_input(array('id'=>'product_naam', 'name'=>'product_naam', 'value' => $product["product_naam"] , 'size'=>25));?></td>
<td><?php echo form_input(array('type'=>'hidden','id'=>'product_id', 'name'=>'product_id', 'value' => $product['product_id']));?>
</tr>
<tr>
<td><?php echo form_open_multipart('Product/upload'); ?> </td>
</tr>
<tr>
<td>
<h4>Kies een categorie</h4>
<select name="category_id">
<?php foreach (get_categories_h() as $category) :
if ($category->id == $product["category_id"]){
echo '<option value="'.$category->id .'" selected>' . $category->name . '</option>';
}else{
echo '<option value="'.$category->id .'">'.$category->name . '</option>';
}
endforeach; ?>
</select>
</td>
</tr>
<tr>
<td><h4>Ophaal plaats</h4><?php echo form_input(array('id'=>'ophaal_plaats', 'name'=>'ophaal_plaats', 'value' => $product["ophaal_plaats"], 'size'=>25));?></td>
<td><?php echo form_input(array('type'=>'hidden','id'=>'ophaal_plaats', 'name'=>'ophaal_plaats', 'value' => $product['ophaal_plaats']));?>
</tr>
<tr>
<td>
<div class="checkbox">
<label><input type="checkbox" value="">Gebruik adres van mijn account</label>
</div>
</td>
</tr>
<tr>
<td>
<h4>Huidig cadeau profiel foto</h4>
<img src="<?php echo base_url(); ?>upload/<?php echo $product['product_foto_thumb']; ?>" class="img-responsive">
</td>
</tr>
<tr>
<td>
<h4>Cadeau profiel foto veranderen</h4>
<input type="file" name="userfile"/>
</td>
</tr>
<tr>
<td><?php echo form_textarea(array('type'=>'textarea','id'=>'product_beschrijving', 'name'=>'product_beschrijving', 'value' =>$product['product_beschrijving'], 'size'=>25));?></td>
<td><?php echo form_input(array('type'=>'hidden','id'=>'product_beschrijving', 'name'=>'product_beschrijving', 'value' => $product['product_beschrijving']));?>
</tr>
<tr>
<td><input type="submit" class="btn btn-primary" name="submit" value="Cadeau bewerken!" /></td>
</tr>
</table>
</form>
This is my controller file (KdGwController.php):
<?php
class KdGwcontroller extends CI_Controller {
public function __construct() {
parent::__construct();
$this->load->model('Product_model');
$this->load->model('Update_product_model');
$this->load->helper(array('form', 'url'));
}
public function details_bewerken($product_id) {
//load the Product_model
$this->load->model('Product_model');
//call function getdata in de Product_model
$data['userdetail_list'] = $this->Product_model->getdata();
//get product details
$data['product'] = $this->Product_model->get_product_details($product_id);
//laad view
$data['main_content'] = 'cadeaubewerken';
$this->load->view('cadeaubewerken',$data);
}
public function update_product() {
$id= $this->input->post('product_id');
$data = array(
'product_naam' => $this->input->post('product_naam'),
'category_id' => $this->input->post('category_id'),
'ophaal_plaats' => $this->input->post('ophaal_plaats'),
);
}
}
And this is my model file : (Update_product_model.php):
<?php
class Update_product_model extends CI_Model {
function update_product($id,$data){
$this->db->where('product_id', $id);
$this->db->update('products', $data);
header ('location:https://kadokado-ferran10.c9users.io//AlleCadeausController');
}
}
?>

Answer 1

No need to add update in model.
Also, your controller update function should be like
public function update_product() {
$id= $this->input->post('product_id');
$data = array(
'product_naam' => $this->input->post('product_naam'),
'category_id' => $this->input->post('category_id'),
'ophaal_plaats' => $this->input->post('ophaal_plaats'),
);
// here I am assuming that `Product` is model
$this->Product->where($id);
$this->Product->update($data);
}

Answer 2

You have not call model function in your controller.
Change your controller update_product() function like this
public function update_product() {
$id= $this->input->post('product_id');
$data = array(
'product_naam' => $this->input->post('product_naam'),
'category_id' => $this->input->post('category_id'),
'ophaal_plaats' => $this->input->post('ophaal_plaats'),
);
$this->Update_product_model->update_product($id,$data);
}

Answer 3

You are not calling function update_product() of Update_product_model.php from KdGwController.php
Change this in your controller...
public function update_product() {
$id= $this->input->post('product_id');
$data = array(
'product_naam' => $this->input->post('product_naam'),
'category_id' => $this->input->post('category_id'),
'ophaal_plaats' => $this->input->post('ophaal_plaats'),
);
$this->Update_product_model->update_product($id,$data); // this line you missed
}
