Question # 11

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?

A.

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.

B.

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.

C.

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.
