Retrieve product's picture url

[german]

I've been searching but found nothing about 1.7 and how to retrieve the url of a specific product. I (finally after some research and work) made my query and I'm able to get the price and name of a product, but I also need the image (actually both images, the small one that appear on previews or thumbnails and the actual size image). 

 

Could you please help me find a solution and also, create a place for people to check for the same question?

Check if you have all the information that you need when you instantiate a Product object:

 

$product = new Product($id);

 

You can get URL calling:

 

Context::getContext()->link->getProductLink($id);

Hello:

This is what you need:

$product = new Product((int)$prod['id_product'], false, $id_lang);
$img = $product->getCover($product->id);
$img_url = $link->getImageLink(isset($product->link_rewrite) ? $product->link_rewrite : $product->name, (int)$img['id_image'], $image_type);

This just get the cover image but you can get all images in the same way. $image_type param give you the specified product image size.

I replaced 'id_product' and 'id_image' by 500 as sample and the result was this:

http://myweb.es/img/p/.jpg

I'm probably doing something wrong, so I hope you could help me with it. I'm trying to create a json (any mean of data reading is valid for me) to get name, price and picture, Taking into account that I have not big idea of php and js, this is all quite new for me. I want to show specific products in a gallery. My idea is to get the reference of the products, send it via js to php, and there retrieve the name, picture and price. So far I have this:

 

$sql = mysqli_query($conn,"SELECT p.price, l.name FROM ps_product p, ps_product_lang l where l.id_product = p.id_product and p.reference=40107");
$rows = array();
while($r = mysqli_fetch_assoc($sql)){
    $rows[] = $r;
}
print json_encode($rows);

I have to find the way to add the URL to $rows[] so it can be parsed correctly for the json. However, I think there is a better way to do this using the php created methods. If you could help me getting closer to want I would like to have, that would be great

Aside of that, where can I find the documentation for the php prestashop methods? (I refer to "Product->getCover", in example).

I thought that prestashop used queries to retrieve the data of the products, but it seems easier* than that. I just need you guys to help me understand it. 
*Nothing it easy when the experience is short. Sigh.

Edit: By the way, shouldn't be the url 'https' by default?

Update: I'm using your code now:
 

$id_a_usar = 37913;
$product = new Product($id_a_usar, false, $id_lang);
$img = $product->getCover($product->id);
$image_type = 'small_default';
print $link->getImageLink(isset($product->link_rewrite) ? $product->link_rewrite : $product->name, (int)$img['id_image'], $image_type);

 

It returns: https://myweb.es/921-small_default/Array.jpg 
Why is it returning Array?

I assume that you are using and specific $id_lang at:

$product = new Product($id_a_usar, false, $id_lang);

Right?

I wasn't. I have only one language, so I thought I wouldn't need one, but I make it work just like follows:

$id_a_usar = $id_got[$n];
$id_lang = Context::getContext()->language->id;
$product = new Product($id_a_usar, false, $id_lang);
$img = $product->getCover($product->id);
$image_type = 'small_default'; //Mirar el ftp para ver otros tipos
$nombre = strtoupper($product->name);
$precio = $product->price;
$imagen = $link->getImageLink(isset($product->link_rewrite) ? $product->link_rewrite : $product->name, (int)$img['id_image'], $image_type);
$url_producto = Context::getContext()->link->getProductLink($id_a_usar);

The only thing that can improve my code (because I'm using a query for it) is to be able to find the ID of a product by the reference. I want to send the references to the php and it should be able to find the product id to operate with them. Is there any way to do this?

You clould do a function similar to Product::getIdByEan13() but searching by reference.
