Unable to load product details page in CodeIgniter

Question

I'm trying to make a product detail page. So when users are on the products page they can click on a specific product to see the details of the products but I'm getting some errors.

This is the all products view page where I'm loading all my products:

<?php foreach($products as $product) : ?>
    <div class="col-lg-2">
        <div id="product">
        <a href="<?php echo base_url() ?>/Product/details">
            <?php  echo '<img src="upload/'.$product['product_foto'].'">' ; ?>
        </a>
        <div class="product_naam"><?php echo $product['product_naam']; ?></div>
        <div class="ophaal_plaats">
           <?php  echo $product['ophaal_plaats']; ?>
        </div>
        <div class="aangeboden_door">
            <p>Aangeboden door: Peter</p>
        </div>
        </div>
        </div>
<?php endforeach; ?>

This is the product detail controller function:

public function details($product_id) {
     //vraag product details
     $data['product'] = $this->Product_model->get_product_details($product_id);

     //laad view
     $data['main_content'] = 'details';
     $this->load->view('details',$data);
 }

This is the product detail view page:

<div class="container">
<div class="row">
<div><?php echo $product->product_naam; ?></div>
    <div class="col-md-4">
          <img src="<?php echo base_url().'upload/'.$product['product_foto'] ?>" class="img-responsive">
    </div>
</div>

And this is the product detail model function:

public function get_product_details($product_id) {
        $this->db->select('*');
        $this->db->from('products');
        $this->db->where('id', $product_id);

        $query = $this->db->get();
        return $query->row();
    }

When I try to load a detail page of a product I'm getting these errors:

Answer 1

This should be your view code (Same as the above answer): And Please make sure that the "$products" contains key named as "id" in it.

<?php foreach($products as $product) : ?>
    <div class="col-lg-2">
        <div id="product">
        <a href="<?php echo base_url() ?>/Product/details/<?php echo $product['product_id']; ?>">
            <?php  echo '<img src="upload/'.$product['product_foto'].'">' ; ?>
        </a>
        <div class="product_naam"><?php echo $product['product_naam']; ?></div>
        <div class="ophaal_plaats">
           <?php  echo $product['ophaal_plaats']; ?>
        </div>
        <div class="aangeboden_door">
            <p>Aangeboden door: Peter</p>
        </div>
        </div>
        </div>
<?php endforeach; ?>

And then in the controller change in the following way:

public function details() {  //Remove product id from arguments
     $product_id = $this->uri->segment('3');
     $data['product'] = $this->Product_model->get_product_details($product_id);
     $data['main_content'] = 'details';
     $this->load->view('details',$data);
 }

And please note that you have to load the URL helper,in case you get error:

$this->load->helper('url');

Answer 2

It is simple. Problem is you are calling your details($productid) methode wrongly. To solve this, in your all product page add product id in <a> tag. see code below .

<?php foreach($products as $product) : ?>
    <div class="col-lg-2">
        <div id="product">
        <a href="<?php echo base_url() ?>/Product/details/<?php echo $product['id']; ?>">
            <?php  echo '<img src="upload/'.$product['product_foto'].'">' ; ?>
        </a>
        <div class="product_naam"><?php echo $product['product_naam']; ?></div>
        <div class="ophaal_plaats">
           <?php  echo $product['ophaal_plaats']; ?>
        </div>
        <div class="aangeboden_door">
            <p>Aangeboden door: Peter</p>
        </div>
        </div>
        </div>
<?php endforeach; ?>
