[php8.1 M2.4.4 EE] stripos expects parameter string, null given

[sheepfy]

Hi, so we have this:

1. This observer: Magento\PricePermissions\Observer\AdminhtmlBlockHtmlBeforeObserver::execute method have this part of code:

       /** @var $block Template */
       $block = $observer->getBlock();
   
       $this->_filterByBlockName($block);
   
       // Handle prices that are shown when admin reviews customers shopping cart
       if (stripos($block->getNameInLayout(), 'customer_cart_') === 0) {

2. The $block::getNameInLayout method is marked with annotation @return string. However, it can return NULL as well which can trigger an issue on php8 in stripos function.

My issue: I'm using a 3rd party module that adds Tabs in it's admin form and I am thinking of adding this condition in AdminhtmlBlockHtmlBeforeObserver::execute :

if (!$block->getNameInLayout()) {
    return;
}

I don't think there is a reason to check anything in that observer if the block name is missing. (even if it's empty string).

Either that, either if the block name is not intended to be NULL update the getNameInLayout() to return only string.

Hello @sheepfy,

Thanks for the posting and collaboration!

We have checked the usage of function setNameInLayout() defined in class lib/internal/Magento/Framework/View/Element/AbstractBlock.php from where $this->_nameInLayout is initialized but in the Magento core, no null value has been passed.

Please let us know which 3rd party module you have tried where you are facing the issue.

Thanks

[sheepfy]

@engcom-Hotel Hey, so it is about implementing Tab forms in admin. Modules in case were Firebear and Xtento_ProductExport . They adds Tabs, tabs will have null as block name and they will fail in that observer.

However, since _nameInLayout can reach as null in that method output, I'll stick to this: if (!$block->getNameInLayout()) { return; }

[engcom-Hotel]

Hello @sheepfy,

Thanks for the response!

I have tried to check the above-mentioned modules in Marketplace and found the below results:

• Firebear :- https://marketplace.magento.com/catalogsearch/result/?q=Fire%20bear
• Xtento_ProductExport :- https://marketplace.magento.com/xtento-productexport.html

I request you to please connect with them and raise a query for this. They might help you.

Thanks

@engcom-Hotel hi, I don't think I can create a PR here with that fix tho, Magento\PricePermissions it's an enterprise module.

[kmosdev]

@sheepfy I had this same issue and created a patch for it.

@kmosdev Hi! That's the patch that I've used, I'd go with "!$block->getNameInLayout()" since the return value is just a string|null and "!" is doing the same thing as "empty"

This fixed an issue on my Commerce edition on version 2.4.5-p1 in which I was getting the same error on a 3rd party module, patching the core magento vendor file as suggested worked wonders, thank you

With a third-party module @plumrocket plumrocket/module-datagenerator:2.6.11 marketplace.magento

I hope it can be useful

> @kmosdev Hi! That's the patch that I've used, I'd go with "!$block->getNameInLayout()" since the return value is just a string|null and "!" is doing the same thing as "empty" > > file: magentoroot/patches/composer/github-issue-35542.diff > > ```diff > diff --git a/Observer/AdminhtmlBlockHtmlBeforeObserver.php b/Observer/AdminhtmlBlockHtmlBeforeObserver.php > index 974b4ec..1978e66 100644 > --- a/Observer/AdminhtmlBlockHtmlBeforeObserver.php > +++ b/Observer/AdminhtmlBlockHtmlBeforeObserver.php > @@ -118,6 +118,9 @@ class AdminhtmlBlockHtmlBeforeObserver implements ObserverInterface > { > /** @var $block Template */ > $block = $observer->getBlock(); > + if (!$block->getNameInLayout()) { > + return; > + } > > $this->_filterByBlockName($block); > ``` > > file: magentoroot/composer.json > > ``` > { > [...] > "extra": { > [...] > "patches": { > [...] > "magento/module-price-permissions": { > "skip composer execution for missing block name": "patches/composer/github-issue-35542.diff" > }, > [...] > } > [...] > } > [...] > } > ```

This is still a problem on 2.4.5-p3 and patch had to be re-applied

For module developers: to avoid this error do not use any Magento Renderer where $_nameInLayout unset or null. Or, create new class which extends Renderer, specify protected $_nameInLayout = ''; and use this new class.

[engcom-Hotel]

Hello @sheepfy,

By looking into the codebase, we can confirm this issue, if $block->getNameInLayout() returns null with php 8.1 or greater.

Hence confirming the issue.

Thanks
