Building Combinations Programmatically

Hi all.

 

I have built an importer that takes a csv from the suppler. Then converts it into a csv file that presta can digest. Everything works fine except it now displays the same image for each size. So if there are several sizes, it will display the same color image for each size.

 

Loads slowly but here you go, have a look:

Here is the bit of code that is being used to build the csv. First part is just column references.

 

#id_product | group | attribute | reference | wholesale_price | price | quantity | minimal_quantity | weight | default_on | image_url | delete_existing_images | ecotax| ean13 | upc | id_shop
$putcsv = array(
			    $prodId,
			    "Color:color:0, Size:select:1",
			    $this->alphaNumOnly($data["COLOR_NAME"]).":0, ".$this->alphaNumOnly($data["SIZE"]).":1",
			    $data["UNIQUE_KEY"],
			    $price_wholesale,
			    $price_retail,
			    $data["QTY"],
			    "1",
			    $data["PIECE_WEIGHT"],
			    $default,
			    $image,
		    "1",
		    "",
		    "",
		    "",
		    "1");
	    fputcsv($file_resource, $putcsv, ";");

 

Thanks for your help!

I would like to find a way where I could do this without having to generate a csv file for the combinations. However this is mostly finished so I can put that off for a while (unless someone has an easy way to do it).

I would expect you have to add the images to an array, indexable with the sizes. Then when you add size S, use $myImagesArray as image, adding size 'M', use $myImageArray[M] etc.

 

so in the code something like similar to

 

...

$data["PIECE_WEIGHT"],

$default,

$myImageArray[sizeVariable],

...

where sizeVariable holds the S, M, L etc,

 

My 2 cents,

pascal

Thanks for your reply.

 

Looking at the examples for other input types of csv files you see that the presta looks for nested arrays like this:

 

whatever; whatever; image1,image2,image3; whatever...

 

I don't know how I would associate an index with these images.

 

whatever; whatever; small:image1,medium:image2,large:image3; whatever...

 

I don't think that will work. Also from the example data it does not say that the images field supports an array.
