Get image url in prestashop

Question

I need to make a feed for my site for a comparing site. It has to be a sql statement. For now I have this:

select  pl.name as Titel,
    ROUND(p.price*1.21,2) as Price,
    replace(concat('http://', ifnull(conf.value,'domain/'), cl.name, '/', p.id_product, '-' , pl.name, '.html'),' ','-') as Link,
     concat('http://', ifnull(conf.value,'domain'), '/img/p/', p.id_product, '-' , pi.id_image, '.jpg') as "Image-location",
     cl.name as Categorie,
    p.id_product AS ID
from dbrb_product p
left join dbrb_image pi on p.id_product = pi.id_product
left join dbrb_product_lang pl on p.id_product = pl.id_product
left join dbrb_category_lang cl on p.id_category_default = cl.id_category
left join dbrb_configuration conf on conf.name = 'dbrb_SHOP_DOMAIN'
left join dbrb_product_carrier x on p.id_product = x.id_product
group by p.id_product

But now with the new prestashop version 1.6 the image doesn't work anymore.

Now the image path is: domain.com/img/p/number/number/number/image.png I don't get the logic from it, can somebody tell me?

There is also another problem I have to deal with, because there are some products which have the same image.

Can somebody complete the SQL code or help me further?

Thanks!

Answer 1

The image path is based on the image id. You split all the digits and add a slash between them to get the folder where the image is stored.

-- build the image path
CONCAT('http://',
        -- get the shop domain
        IFNULL(conf.value, 'undefined_domain'),
        -- the path to the pictures folder
        '/img/p/',
        -- now take all the digits separetly as MySQL doesn't support loops in SELECT statements
        -- assuming we have smaller image id than 100'000 ;)
        IF(CHAR_LENGTH(pi.id_image) >= 5, 
            -- if we have 5 digits for the image id
            CONCAT(
                -- take the first digit
                SUBSTRING(pi.id_image, -5, 1),
                -- add a slash
                '/'),
            ''),
        -- repeat for the next digits
        IF(CHAR_LENGTH(pi.id_image) >= 4, CONCAT(SUBSTRING(pi.id_image, -4, 1), '/'), ''),
        IF(CHAR_LENGTH(pi.id_image) >= 3, CONCAT(SUBSTRING(pi.id_image, -3, 1), '/'), ''),
        if(CHAR_LENGTH(pi.id_image) >= 2, CONCAT(SUBSTRING(pi.id_image, -2, 1), '/'), ''),
        IF(CHAR_LENGTH(pi.id_image) >= 1, CONCAT(SUBSTRING(pi.id_image, -1, 1), '/'), ''),
        -- add the image id
        pi.id_image,
        -- put the image extension
        '.jpg') as image_url

Answer 2

The number in the paths to an image is the digits of its ID, for example image with ID 121 will have the following path:

http://domain.com/img/p/1/2/1/121.jpg

However, MySQL doesn't have any built-in functions to do this (AFAIK), so you will need to build a user-defined function.

Answer 3

Here $productID is your product's ID :)

$prod = new Product($productID);
$imgArray = $prod->getImages('1');
if (count($imgArray)>0) {
    $imgID = $imgArray[0]["id_image"];
    $imageUrl=_THEME_PROD_DIR_.Image::getImgFolderStatic($imgID).$imgID.".jpg";
}

Answer 4

Use the prestashop class "IMAGE" instead of loading MySql with functions

public static function getImgFolderStatic($id_image)

Returns the path to the folder containing the image in the new filesystem

It strips the number of the image into the subfolders used by prestashop.

Example:

foreach($SQLresult as $key=>$value)
   {
      $imageUrl=_PS_PROD_IMG_DIR_.Image::getImgFolderStatic($value['id_image']).$value['id_image'].".jpg"
   }

Answer 5

Is simple, replace concat from your query for this one:

concat('http://', ifnull(conf.value,'example.com'), '/img/p/',SUBSTRING(pi.id_image from -4 FOR 1),'/',SUBSTRING(pi.id_image from -3 FOR 1),'/',SUBSTRING(pi.id_image from -2 FOR 1),'/',SUBSTRING(pi.id_image from -1 FOR 1),'/' , pi.id_image, '.jpg') as product_image,

Answer 6

Mh, im using this: concat('http://', ifnull(conf.value,'example.com'), '/img/c/', c.id_category, '.jpg') as url_image,

it works perfect.
