PHP version change, like the LAMP app?

d19dotca

Hi there,

Curious... are we able to change the PHP version in the WordPress app just like we can in the LAMP app? (https://docs.cloudron.io/apps/lamp/#supported-php-versions)

If not, is it possible to perhaps add that type of functionality from the LAMP app in other PHP-based app packages?

This should be possible. What's the use case though? WP is not fully compatible with PHP 8 or 8.1 at this point.

d19dotca

@girish Ah interesting read. It may not be fully compatible but is still running fine for many people on PHP 8.0 from what I've been reading in various FB groups, plus it's still a supported version of PHP for WordPress whether fully compatible or not. A few of the page builders I use (namely Bricks and Oxygen) are now PHP 8.0 compatible and all the plugins I use appear to be too, so figured I may as well upgrade to 8.0 for the bit of performance improvements.

I think ideally though that's where you could use the same formula you have for the LAMP app where it's 7.9 by default and can only be 8.0 once it's configured to be so manually using that switch you added. For consistency sake, I'd think that should perhaps be added to all PHP-based apps, but that's just my two cents.

@d19dotca Not opposed to it. We will move to Ubuntu 22 based image in the recent future, we can have multiple PHP versions in the base image itself.

However WP 6 is rolling out right now, I haven't checked yet, but I guess it should be fully compatible now... we've yet to see...

That'd be awesome! Thanks Girish!

@girish was there any progress on this one? Doesn’t seem we have PHP 8 supported yet on the packaged app for WordPress Developer.

girish

@d19dotca yeah, I will switch the default for a start to PHP 8. PHP 7.4 EOL is coming up in 15 days or so.

d19dotca

@girish Ah okay, so in that case I guess this will be a “manual intervention required” type of update rather than automatic? And no way to switch back inside of the app itself but would have to deploy the older image if compatibility issues exist? If plugins are up to date it likely won’t be a problem but anyone relying on older rarer plugins I could assume will experience issues. Thankfully all mine are pretty current plug-ins so I’m not anticipating any issues and am actually looking forward to the performance improvements with PHP 8.

girish

@d19dotca yeah, I pushed updates for LAMP and both WP just some time back. They are major upgrades.

Hi guys,

Is there any progress on this issue?

It would be nice to have the possibility of choosing the PHP version in the WordPress Developer application so that updates do not accumulate.

In some complex WordPress installations, where there are plugins that the developer has not yet adapted to the PHP 8.1 version, they already accumulate 4 updates (3.0.0, 3.0.1, 3.0.2 and 3.0.3) without any possible alternative to update them.

Is there any estimation of what version will be available?

Thanks team!

@martinkbs Are you asking for PHP 7.4 for WordPress ? It reached EOL in Nov 2022 - https://www.php.net/eol.php .

martinkbs

Hi @girish,

Yes, I am aware of that. But it would be nice to have the possibility of php version choice like in LAMP application.

Even if the WordPress Developer application is installed by default on version 8.1, that somehow it can be downgraded to version 7.4 for those installations that have plugins or themes that have not yet been adapted by their developers.

I know I can migrate WordPress installations to a LAMP application, but this way I would lose WP-CLI functionality, and that is something important to keep automations with n8n.

girish

@martinkbs mmm, have to think about the viability of this. Every passing day makes 7.4 more unsupportable. In fact, 7.4 doesn't exist in ubuntu core repos and this complicates the WP app packaging. We use this PPA. This is actually why we rushed updating all our apps to base image 4.0 which has PHP 8 and removed the ondrej repo. I think if WP itself didn't support PHP 8, this decision might have been simpler. But this is some plugin of WP...

For wp-cli, you only need to get the phar file in https://github.com/wp-cli/wp-cli/releases/ . It's a single file you can put somewhere in /app/data and run .

@girish I am trying to install wp-cli in the LAMP application and I get the following error:

You can make the file executable as chmod +x wp and then do ./wp (the ./ is important)
