Invalid $number parameter: "" cannot be interpreted as a number

[alj]

Hi

On a Prestashop 1.7.7.1 i'm getting this error when going to the product overview in back office.

it is a new fresh install, and before I imported products I could fine access the product overview , but now after importing products, i get this error.
Have tried changing decimals under currencies, deleting cache and changing currency, nothing helped.

Has anyone experienced this error and may have a solution.

Thanks!

I have exactly the same problem

[musicmaster]

It looks like it has a NULL or "" value for price. So you will need to have look at the price field the ps_product_shop in the database and see if there are null values there.

Do you have a multistore?

Yes, it's a multistore

As a temporary solution, add an IF in these lines:

https://github.com/PrestaShop/PrestaShop/blob/6cc8f20c2a5675d754c5566adf76ec6ac25ef901/controllers/admin/AdminCartRulesController.php#L573

to check if $product['price_tax_incl'] or $price_tax_incl is not null.

I had what appears to be the same problem. This solved it.
Add this logic to the if on line 390 in src/Adapter/Product/AdminProductDataProvider.php

if ($formatCldr && $product['price'] != null && $product['price_final'] != null) {
  $product['price'] = $localeCldr->formatPrice($product['price'], $currency->iso_code);
  $product['price_final'] = $localeCldr->formatPrice($product['price_final'], $currency->iso_code);
}

Thank you, works properly on PS 1.7.7.1

The above worked for me. However, this bug still exists in P.S. 1.7.7.4 has it been reported to PrestaShop?

Switch to older PHP version 7.1 or 7.2

It's not related with PHP version.

Who are you replying to? It makes no sense to change to an older version of PHP when PrestaShop 1.7.7.x supports 7.3

I got similar problem with the module and was resolved when I switch to older PHP

This is not a module. It is core PrestaShop.

The shop I work on already uses PHP 7.2 so it did not work for me before changes were made (upgraded shop from 1.6 to 1.7)

I copy this code exactly and it works on Prestashop 1.7.7.5.

IF add to this line in this version but this part has changed

product['price'] != null && $product['price_final'] != null) {

Not work for me! =l 

 

if ($formatCldr && $product['price'] != null && $product['price_final'] != null) { $product['price'] = $localeCldr->formatPrice($product['price'], $currency->iso_code); $product['price_final'] = $localeCldr->formatPrice($product['price_final'], $currency->iso_code); }

Because your problem is in another function.

First of all, which PHP version are you using?

Worked for me too on upgraded prestashop 1.7.7.5. Thank you!

It helped me in version 1.7.8.1 with PHP 7.4
===============================
@Asger22

15-02-2022 
Unfortunately, the problem reappears in version 1.7.8.3 - after updating the above code in the AdminProductDataProvider.php file, I can now access the product catalog.
I must point out that for the last 15 days after updating the store from version 1.7.8.2 it worked without corrections, but today something crashed and I had to go back to modifying the file.
Fortunately, the patch works. 🙂

I have exactly the same problem  in version 1.7.8.2 multistore with PHP 7.4.

Probably you have the same error but in another part of code. Please upload a screenshot.

[Webmain]

EDIT SOLVED!!

Well then the problem is super simple in the end but however you need to put the code as given above see below:

Add this logic to the if on line 390 in src/Adapter/Product/AdminProductDataProvider.php

if ($formatCldr) {
  $product['price'] = $localeCldr->formatPrice($product['price'], $currency->iso_code);
  $product['price_final'] = $localeCldr->formatPrice($product['price_final'], $currency->iso_code);
}

PAR

if ($formatCldr && $product['price'] != null && $product['price_final'] != null) {
  $product['price'] = $localeCldr->formatPrice($product['price'], $currency->iso_code);
  $product['price_final'] = $localeCldr->formatPrice($product['price_final'], $currency->iso_code);
}

Then when you have all the products displayed, search in the page or pages for the mention N/D of the column Amount including tax

Edit the product and delete all the combinations (shops only) Then save then put all the shops and recreate the combinations! Then modify the variations for each shop and save for each of the shops then go back to all the shops then save until you have the updated product message!!

Do this for all products with N/D then once finished you can remove the piece of code :).

Problem solved !!

In the future create your variations before on all the shops then configure each shop their price etc ..

Yes, this is the solution given in a previous answer

not quite that just unblocks the situation. read the rest of my post to solve the problem, because in case of updating the prestashop the code will be replaced again

[Yulia Vitun]

In my case this error appears after upgrade from PS 1.7.6.5 to PS 1.7.8.6,  and only when I click on Stats Dashboard link in back office.

Solution: as per this fix in src/Core/Localization/Locale.php, to add just one line 152:

if ( $number === null ) return null;

The final view:

    public function formatPrice($number, $currencyCode)
    {
      if ( $number === null ) return null;
        return $this->numberFormatter->format(
            $number,
            $this->getPriceSpecification($currencyCode)
        );
    }

    }

 

This work for me. In my case, I cant enter to backoffice cart list.

[Yulia Vitun]

....also I found this solution: 

to add this if logic to the line 390 in src/Adapter/Product/AdminProductDataProvider.php

if ($formatCldr && $product['price'] != null && $product['price_final'] != null) {
  $product['price'] = $localeCldr->formatPrice($product['price'], $currency->iso_code);
  $product['price_final'] = $localeCldr->formatPrice($product['price_final'], $currency->iso_code);
}

I add two solutions mentioned, lets see ))

De mon coté j'ai résolu me problème de la manière suivante

Dans /src/core/Localization/Number/formatter.php

j'ai ajouté ligne 105

if (empty($number)){$number='0.000000';}

Pas top mais bon ça corrige le problème

Hello,

I have this issue too and I don't found a good solution. Your solution can maybe work but it is not recommended to override the src folder. So I don't really understand how I can solve the problem.

It's safe to change this line.

Yes I understand this but if in the next time I want to upgrade my prestashop version, the line added will be disappear
