Hi, what happens if

• user installs PS 1.7.7 with php7.4
• so we display the yellow warning
• user downgrades php to php7.3
• so we display the green message once, then nothing
• now user upgrades PS 1.7.7 to PS 1.7.9
• and unfortunately PS 1.7.9 is not compatible with php7.3 ! it needs php7.4 or php8.0
• so we should display again the yellow warning?

Todo:
@matks' case is handled, just need to be clarified

[LouiseBonnard]

@matks, @MatShir, there are two cases at stake, starting from the 1.7.8 version:

1. the PHP version matches the PS version: no warning message
2. the PHP version doesn't match the PS version: a warning message is displayed. The warning message is the same for inferior or superior not supported version,

@matks Could you please verify a last time this specs and tell us if it's ok for you before the merge ?

Hi @marionf What about this usecase

user installs PS 1.7.7 with php7.4
so we display the yellow warning
user downgrades php to php7.3
so we display the green message once, then nothing
now user upgrades PS 1.7.7 to PS 1.7.9
and unfortunately PS 1.7.9 is not compatible with php7.3 ! it needs php7.4 or php8.0
so we should display again the yellow warning?

[MatShir]

The only cases can we handle are:

• the PHP version matches the PS version: no warning message
• the PHP version doesn't match the PS version: a warning message is displayed. The warning message is the same for inferior or superior not supported version
  @matks which handle your cases

[MatShir]

Suggested change

	_As a user, I want to know when my PHP version is not suitable - no longer supported or not yet supported._
	_As a user, I want to know when my PHP version is not suitable - no longer supported or not yet supported._
	If the PHP version matches the PHP compatibility of PrestaShop: no warning message is displayed.
	If the PHP version doesn't match the PHP compatibility of PrestaShop: a warning message is displayed. The warning message is the same for inferior or superior not supported version.

I add a last comment, to make it more explicit. WDYT @matks @marionf

[matks]

@MatShir My usecase is "what happens when on Monday I see the warning message, then on Tuesday I modify my php version, now the message is dismissed, then on Wednesday I upgrade my shop, then on Thursday again my PHP version is not good but I have previously already dismissed the message"

[MatShir]

@matks I get it now, thanks for the clarifications.
I see 2 options:

• this use case that can be done on a V2, it looks like an edge case. BC people upgrading their PHP version should be aware of the compatibility of PS, but people can forget to follow the PS compatibility.

Upgrading first PHP then upgrading the version should work since there is a common version (cf. https://devdocs.prestashop.com/1.7/basics/installation/system-requirements/#php-compatibility-chart)

• The message state is reset to any PHP version changes
  If the second option is hard to implement, we should focus on the common uses cases with "is your shop compatible ? Yes or not"

WDTY ?
