How does it work to get products images combination in product.tpl ?

[Cloud Nine]

Hello,

Can you explain me how this code works in product.tpl ?

I know php, JavaScript so i understand that there is a foreach loop that fill a JavaScript array.

But i can’t find where the php array is from. It should be in Product.php Class but i don’t find it.

I ask because i try to understand how to get combination product images.

Thanks

 

the code :

// Images
var img_prod_dir = '{$img_prod_dir}';
var combinationImages = new Array();

{if isset($combinationImages)}
    {foreach from=$combinationImages item='combination' key='combinationId' name='f_combinationImages'}
        combinationImages[{$combinationId}] = new Array();
        {foreach from=$combination item='image' name='f_combinationImage'}
            combinationImages[{$combinationId}][{$smarty.foreach.f_combinationImage.index}] = {$image.id_image|intval};
        {/foreach}
    {/foreach}
{/if}

combinationImages[0] = new Array();
{if isset($images)}
    {foreach from=$images item='image' name='f_defaultImages'}
        combinationImages[0][{$smarty.foreach.f_defaultImages.index}] = {$image.id_image};
    {/foreach}
{/if}

Try in :

/controllers/front/ProductController.php

 

This is the file that calls product.tpl, and here are the smarty vars set.

 

Like:

 

$this->context->smarty->assign(array(

'groups' => $groups,

'combinations' => $combinations,

'colors' => (count($colors)) ? $colors : false,

'combinationImages' => $combination_images));

 

 

 

hope that helps,

Hello,

Thank you very much. It helps me !

So, ProductController generates the product page.

I found the method assignAttributesCombinations in the ProductController class. I understand that assignAttributesCombinations get and assign attributes combinations informations.

I’m creating a module that show all products in a category with all combinations. So, i should use assignAttributesGroups, do you think it’s correct ?

I was using getCombinationImages and getAttributeCombinations to get combinations datas of the products in a loop like this :

$products is an array that contains all product of a category.

for ($i = 0; $i < count($products); $i++) {
                $combinations[$i] = $this_product->getCombinationImages($params['cookie']->id_lang);
}

print_r($combinations);

what do you think of that ?

 

Thanks, best regards,

Hello,

First, thank you for your help.

I’ve downloaded your module and studied it. I understand how it works. In fact, i was able to do that before asking for some help here. But it shows me that i was in the right direction.

So, to explain what i try to do, let’s have a look at this picture :

 

I try to make a product listing that shows all product with their combinations. On the picture, you will see that there are products with id 1, 2, 3 that have no combination. Then, product with id = 4 have 3 combinations and we can see the 3 images on the product list.

Is that clear for you or not ?

Si, i have made a module.

First, i get all the products in a category :

$category_1 = new Category(4, Configuration::get('PS_LANG_DEFAULT'));
$products = $category_1->getProducts((int)($params['cookie']->id_lang), 1, ($nb ? $nb : 10));

So, i have all my products.

Then, i make a loop to get all the combination. It works, you can test.

$combinations = array();
for ($i = 0; $i < count($products); $i++) {
                $this_product = new Product($products[$i]['id_product']);
               $combinations[$i] = $this_product->getAttributeCombinations($params['cookie']->id_lang);

If we print the array or make a {debug} in smarty, we see the content of the array :

Array
(
[0] => Array
(
[0] => Array
(
[id_product_attribute] => 165
[id_product] => 143
[reference] => XXXX-B6RG
[supplier_reference] =>
[location] =>
[ean13] =>
[upc] =>
[wholesale_price] => 0.000000
[price] => 0.000000
[ecotax] => 0.000000
[quantity] => 43
[weight] => 0.000000
[unit_price_impact] => 0.00
[default_on] => 1
[minimal_quantity] => 1
[available_date] => 0000-00-00
[id_shop] => 1
[id_attribute_group] => 2
[is_color_group] => 1
[group_name] => Couleur
[attribute_name] => Rouge
[id_attribute] => 6
)

[1] => Array
(
[id_product_attribute] => 166
[id_product] => 143
[reference] => XXXX-B6BE
[supplier_reference] =>
[location] =>
[ean13] =>
[upc] =>
[wholesale_price] => 0.000000
[price] => 0.000000
[ecotax] => 0.000000
[quantity] => 53
[weight] => 0.000000
[unit_price_impact] => 0.00
[default_on] => 0
[minimal_quantity] => 1
[available_date] => 0000-00-00
[id_shop] => 1
[id_attribute_group] => 2
[is_color_group] => 1
[group_name] => Couleur
[attribute_name] => Bleu
[id_attribute] => 8
)

// and so on

If i use getCombinationImages, i can also get id_image so i guess i am very closed to the solution :

Array
(
[0] => Array
(
[165] => Array
(
[0] => Array
(
[id_image] => 58
[id_product_attribute] => 165
[legend] =>
)

)

[168] => Array
(
[0] => Array
(
[id_image] => 156
[id_product_attribute] => 168
[legend] =>
)

)

Here, what i'm missing is how to used this aray in smarty beacause a simple foreach doesn't work because the array is really complex.

 

do you think i need to change something ?

 

thank you for your advices.

Maybe it helps if you play a little with it here:

I made some arrays that mimic the code you presented above. At the end you see the (indeed complex) array code. I can imagine though that to get the values using the objects instead of the arrays directly it may be easier.....

$arr = array
(array
(array
(
'id_product_attribute' => 165,
'id_product' => 143,
'reference' => XXXX-B6RG,
'supplier_reference' => null ,
'location' => null,
'ean13' => null,
'upc' => null,
'wholesale_price' => 0.000000,
'price' => 0.000000,
'ecotax' => 0.000000,
'quantity' => 43,
'weight' => 0.000000,
'unit_price_impact' => 0.00,
'default_on' => 1,
'minimal_quantity' => 1,
'available_date' => 0000-00-00,
'id_shop' => 1,
'id_attribute_group' => 2,
'is_color_group' => 1,
'group_name' => Couleur,
'attribute_name' => Rouge,
'id_attribute' => 6,
),
array
(
'id_product_attribute' => 166,
'id_product' => 143,
'reference' => XXXX-B6BE,
'supplier_reference' => null ,
'location' => null,
'ean13' => null,
'upc' => null,
'wholesale_price' => 0.000000,
'price' => 0.000000,
'ecotax' => 0.000000,
'quantity' => 53,
'weight' => 0.000000,
'unit_price_impact' => 0.00,
'default_on' => 0,
'minimal_quantity' => 1,
'available_date' => 0000-00-00,
'id_shop' => 1,
'id_attribute_group' => 2,
'is_color_group' => 1,
'group_name' => Couleur,
'attribute_name' => Bleu,
'id_attribute' => 8,
)
));


$imgarr = array
(array
(
"165" => array
(array
('id_image' => 58,
'id_product_attribute' => 165,
'legend' => null
)
),

"168" => array
(array
(
'id_image' => 156,
'id_product_attribute' => 168,
'legend' => null
)
)
));


echo '$arr = ';
print_r($arr);
echo'<br />';
echo'<br />';

echo '$imgarr = '; 
print_r($imgarr); 
echo'<br />'; 
echo'<br />'; 

echo "example of how the get first id_prod_atr =".$arr[0][0][id_product_attribute]; 
echo'<br />'; 
echo "example of how the get second id_prod_atr =".$arr[0][1][id_product_attribute];
echo'<br />';

// try out step, if we want image array contents of attr 165 
echo "image array contents of attribute 165 = "; 
print_r($imgarr[0][165][0]); 
echo'<br />'; 

echo "image of first attribute ".$arr[0][0][id_product_attribute]." is ".$imgarr[0][$arr[0][0][id_product_attribute]][0][id_image];

Copy the code to the online php coder and play with it a little. Maybe this gives some more insight....

Hi,

 

How to show the unitprice impact for the products involving product combinations...

[Guest locen]

Hi, i have this problem with combinations:

 

- I enabled the combinations and with the first visualization you show also photos that are only for the other combination.

- Then if you change combination and you rechange combinations like the first time all photos are will be ok like image associated with the combinations. 

 

can anyone help me?
