Problems with PHP 8.1

[dendemeier]

Last week I upgraded my forum to 2.0.19. Since then I set up the php-version in the server´s control Panel to 8.1, but now there are many mistakes in the error log.

The most common one is:

Code Select Expand

8192: preg_replace_callback(): Passing null to parameter #3 ($subject) of type array|string is deprecated
File: /home/prlxboxf/public_html/forum/Sources/Load.php
Line: 178
The code in Load.php is as following:

Code Select Expand



// Set a list of common functions.
175: $ent_list = empty($modSettings['disableEntityCheck']) ? '&(?>#\d{1,7}|quot|amp|lt|gt|nbsp);' : '&(?>#021|quot|amp|lt|gt|nbsp);';
176: $ent_check = empty($modSettings['disableEntityCheck']) ? function($string, $double = false)
177: {
178: $string = preg_replace_callback('~(&' . (!empty($double) ? '(?:amp;)?' : '') . '#(\d{1,7}|x[0-9a-fA-F]{1,6});)~', 'entity_fix__callback', $string);
179: return $string;
180: } : function($string)
181: {
182: return $string;
183: };

Is there a workaround to solve this?

Also with PHP 8.1 the e-mail for resetting a password isn´t send to a user. With 7.4. it´s working. But i don´t know if the error is responsible for it or if this i an other problem.


For now I switched back to PHP 7.4. But there is also an error. Priority is to get the forum work with php 8.1. But if this doesn´t work, I want to get rid of this mistake as well.

$context['continue_countdown'] = 5;
return false;
}
The error is shown for line

Hi,

As per this, SMF 2.0.19 does not currently support PHP 8.1.

[dendemeier]

Ah, alright. I didn´t see that. Thanks

I switched back to php 8.0, but the forum isn´t working at all. So I´m staing at 7.4.


Is there a solution for an error which is shown under php 7.4?

Are you using any mods, if so which ones?
Any reason why you're not upgrading to 2.1 branch though?

[dendemeier]

I´m using several mods:

dQuote Selection and Notification 2,7,6
Event Registration Mod for SMF2 2,36
Spoiler BBCode 1,1,3
Advanced Recent posts 1,1,1
mention members 1,1,2
Alternate User Postung 1,0,1
Anti-Spam by Cleantalk 2,36
Recent Forum Topics Boardindex 1,2
Birthday on Profile Summary v2 2,1
Top First Post 2,0,6
Discord Web Hooks 2,0,1
Ohara YouTube Embed 1,2,13
Post Scheduler 1,0,1

But the error appears only when entering the admin-area.


And for this:

Any reason why you're not upgrading to 2.1 branch though?

Yes. The main reason is that the theme of the forum isn´t compatible with 2.1. I´m using "Gaming Nation" from SMF Tricks and we want to switch to "Darkly", also from SMF Tricks and for now it is unclear, if they will update their themes to 2.1.

So for now i´m sticking with 2.0.19

[Kindred]

Since inline attachments is not a feature in 2.0.x, that file is from a mod -- which may not be compatible with php 7.4

[dendemeier]

Ah, maybe it was a file from an attachement mod. I renamend the file, now everything works perfectly. Thank you

[Arantor]

Renaming files is always a bad idea, it just means you broke the mod.

[Diego Andrés]

Indeed something is wrong if you don't have it installed anymore (according to your list of installed mods).

The current person supporting that mod is very active so you should definitely bring this into the support topic: https://www.simplemachines.org/community/index.php?topic=525705.0
I assume it's that mod.

Hi,

As per this, SMF 2.0.19 does not currently support PHP 8.1.

Hmm, does 2.0.19 really not support PHP 8.1 and if so, is the 2.0.19 announcement somewhat misleading where it says "Ensures compatibility with PHP 8.1 MySQLi error mode"? Link to the announcement here

[Aleksi "Lex" Kilpinen]

2.0.19 fully supports PHP 5.3 - 8.0. ( Devs, do correct me if I'm wrong here. )
There may be changes in 2.0 code aimed at partial support or future proofing, but officially the version requirements for each 2.0 release are listed at https://wiki.simplemachines.org/smf/SMF2.0:Requirements_and_recommendations
