Foreach not giving me any result - php

Question

Hello guys!
I'm trying to use a foreach cicle to show some images from my disk but something is getting wrong. It show and error saying
Message: Array to string conversion
Line Number: 306
Here is my foreach cicle
<div class="col-lg-9">
<div class="row">
{foreach $products as $product}
<div class="col-lg-4 col-md-6 mb-4">
<div class="card h-100">
<img class="card-img-top border-bottom" src="{$product.image}" alt="">
<div class="card-body">
<h6 class="card-title">
<p class="text-dark">{$product.name}</p>
</h6>
</div>
<button type="button" class="btn btn-secondary"><i class="material-icons">local_grocery_store</i><span class="float-right mr-4">Adicionar ao carrinho</span></button>
</div>
</div>
{/foreach}
</div>
</div>
My error said the problem is on this line
$data['products'] = '.base_url(' . $this->Cart_model->get_img() . ').';
Also my model with get_img() is this
public function get_img(){
$sql = "SELECT * FROM products";
$query = $this->db->query($sql);
return $query->result();
}
and this is my database

Answer 1

I think the issue is that you're using base_url to call the model, remove the base_url and then call the model. Like this -
$data['products'] = $this->Cart_model->get_img(); // returns array of objects
In your view file, use foreach to traverse the data then you'll have to do something like
<?php echo base_url()."path/to/folder/$product->table_image_column"; ?>
View (in php) // this is how I'd do.
<?php foreach($products as $product) { ?>
<div class="col-lg-4 col-md-6 mb-4">
<div class="card h-100">
<img class="card-img-top border-bottom" src="<?php echo base_url()."your/path/$product->image"; ?>" alt="">
<div class="card-body">
<h6 class="card-title">
<p class="text-dark"><?php echo $product->name; ?></p>
</h6>
</div>
<button type="button" class="btn btn-secondary"><i class="material-icons">local_grocery_store</i><span class="float-right mr-4">Adicionar ao carrinho</span></button>
</div>
</div>
<?php } ?>
or if you're using any framework and don't want to mingle php in it. Use foreach in the controller itself and add base_url() to the image. You don't have to make any changes in the view for this-
Controller
$i= 0;
foreach($products as $product) {
$products[$i]->image = base_url()."path/to/image/$product->image"; // change the products array with new values
$i++;
}
See if it helps you.

The answer is add src="<?php echo base_url('{$product.image}'); ?>" in the Views
<div class="row">
{foreach $products as $product}
<div class="col-lg-4 col-md-6 mb-4">
<div class="card h-100">
<img class="card-img-top border-bottom" src="<?php echo base_url('{$product.image}'); ?>" alt="" style="width:30px;height:30px;">
<div class="card-body">
<h6 class="card-title">
<p class="text-dark">{$product.name}</p>
</h6>
<div class="text-danger"><b><span>{$product.price}€ </span></b><span class="text-secondary float-right"><del>{number_format((float)$product.price*1.5, 2, '.', '')}€</del></span></div>
</div>
<button type="button" class="btn btn-secondary"><i class="material-icons">local_grocery_store</i><span class="float-right mr-4">Adicionar ao carrinho</span></button>
</div>
</div>
{/foreach}
</div>
