An Adobe Commerce Developer is tasked with creating a custom form which submits its data to a frontend controller They have decided to create an action and have implemented the \Magento\Framework\App\Action\HttpPostActioninterface class, but are not seeing the data being persisted in the database, and an error message is being shown on the frontend after submission.After debugging and ensuring that the data persistence logic is correct, what may be cause and solution to this?

Form key validation runs on all non-AJAX POST requests, the developer needs to add the for_key to their requests.

Magento does not allow POST requests to a frontend controller, therefore, the submission functionality will need to be rewritten as an API endpoint.

The developer forgot to implement a validatePostDataQ method in their action. They should implement this method: all non-validated POST data gets stripped out of the request and an error is thrown.

An Adobe Commerce developer has installed a module from a third-party vendor. This module fires a custom event named third_party_event_after and also defines an observer named third_party_event_after_observer that listens to that event. The developer wants to listen to this custom event in their own module but wants to execute their observer's logic after the third_party_event_after_observer observer has finished executing.What would the developer do to ensure their observer runs after the observer defined by the third-party module?

Set the sort order of the new observer to be less than that of the third-party vendor's observer.

Ensure the third-party module is listed in the <sequence> node of the developer's module.xmi file.

Set the sort order of the new observer to be less than that of the third-party vendor's observer.

This is not possible as observers listening to the same event may be invoked in any order.

An Adobe Commerce developer is working on a Magento 2 instance which contains a B2C and a B2B website, each of which contains 3 different store views for English, Welsh, and French language users. The developer is tasked with adding a link between the B2C and B2B websites using a generic link template which is used throughout the sites, but wants these links to display in English regardless of the store view.The developer creates a custom block for use with this template, before rendering sets the translate locale and begins environment emulation using the following code: They find that the template text is still being translated into each stores language. Why does this occur?

startEnvironmentEmuiation() resets the translation locale to the one of the emulated stores, which overrides the locale the developer has set when the order of setLocate and startEnvironmentEmulation is used as displayed above.

startEnvironmffntEmulation() SetS and locks the locale by Using the setLocale() Optional Second $lock parameter, i.e. setLocale($newLocaleCode, true), to override and lock the locale of the emulated store. If this is set and locked initially then the environment emulation will not be able to override this.

startEnvironmentEmuiation() resets the translation locale to the one of the emulated stores, which overrides the locale the developer has set when the order of setLocate and startEnvironmentEmulation is used as displayed above.

setLocate() does not change translation locale after it has been initially set, the $this->_translate->emulate($newLocaiecode) method exists to temporarily modify this by pushing the new locale to the top of the current emuiatedLocales stack.

An Adobe Commerce Developer wishes to add an action to a pre-existing route, but does not wish to interfere with the functionality of the actions from the original route.What must the developer do to ensure that their action works without any side effects in the original module?
