And - if you don't keep switching php modes you won't have to worried about php open tags except at the beginning of your script. Here is the last post of code you submitted. See if it makes sense to you how I converted your coding. Don't know what that addquote thing is but I assumed it was a Php function name. <?php if(!defined('IN_DISCUZ')) exit('Access Denied'); $code=<<<heredocs <html> <head> <meta http-equiv="Content-Type" content="text/html; charset="$CHARSET" /> <meta http-equiv="MSThemeCompatible" content="Yes" /> <meta name="description" content="" /> <meta name="keywords" content="" /> <meta name="MSSmartTagsPreventParsing" content="TRUE" /> heredocs; echo $code; include template('css'); $code=<<<heredocs <script type="text/javascript" src="include/common.js"> </script> <link href='include/mh_css_6.css' type='text/css' rel='stylesheet'> heredocs; echo $code; addquote('$url_redirect'); echo " <title>"; addquote('$bbname'); addquote('$navtitle'); echo " </title> </head> <body>"; I will try it when the web is back online from restoration.

This is not a problem you can fix by editting source code. You are running a forum that has templates it compiles and runs. Changing the source code of the forum or these templates, other than via one of their official patch/upgrade packages isn't going to work. There is nothing wrong with the code as it was before, and people were confused into thinking that changing it was going to fix errors, because they did not understand that these were templates that get parsed and compiled into a finalized PHP source. In short, if you changed any files, hopefully you can change them back to what they were originally. It is likely you do need short open tags to be on, but that is not the primary problem. The primary problem is that you are running a version of Discuz! that is incompatible with php7 and needs to be patched. As this forum is not well known in the english speaking world, it's doubtful that anyone here can be much help to you, but I did find a page that appears to link to some patches and upgrade instructions.

So let's review: Site was running PHP 7, and was functional Site is now running PHP8 and is broken 2 Years ago, a programmer did *something* with the forum, but you don't know what that something was... An educated guess would be that they upgraded the version of Discuz to the version that runs under PHP7. Here's something helpful for you: https://www.discuz.net/daily/ This is the page of Discuz! Daily builds. Note that the current version of the forum is 3.4. So that is the newest current version. Here is a thread talking about how Discuz 3.4 does not work with PHP8, and there are people stating due to architecture and plugins, that there is no way it's going to be updated to work with php8. https://www.discuz.net/thread-3852727-1-1.html Based on what I can see, your only viable option is a downgrade of PHP to version 7.4. It will be supported until November, and at that point it will be End of life, so you are not yet in a situation where PHP 7.4 should not be used. Regardless of PHP 7.x's status you are beholden to the support or lack thereof, for Discuz! In conclusion: you need to downgrade the server to PHP 7.4. Don't know what Distro you are using, or what level of control you have over it, but that is what I'd be looking to accomplish at this point. Of course this all makes way more sense now that we've established that: System worked fine with php7.x Broke after upgrade to 8.x Quote Link to comment Share on other sites More sharing options...

ginerjm Posted April 24, 2022 Share Posted April 24, 2022 Those error messages are telling you that there is an error on line 19. They are NOT telling you that "the web is down...". Show us line 19. PS - many voices here will tell you that you never need to use a PHP closing tag (?>) . So if you follow my previous example (above) if you never try to output html 'outside' of php mode, you'll never need to use a closing tag. Not to brag but I write very long scripts sometimes a 1000 lines and I never leave PHP mode. Quote Link to comment Share on other sites More sharing options...
ginerjm Posted April 24, 2022 Share Posted April 24, 2022 Looking at your old posts here I found this "line 19". <title> addquote('<?=$bbname?' . '>') addquote('<?=$navtitle?' . '>') </title> I broke it down to make it easier to discuss. Can you see now that you have mis-used the php closing tags here? And just what exactly is "addquote()" Is it a php function? If it is you are definitely not using it correctly. The code all around line 19 is HTML code and right in the middle of it you are introducing a php function call. If you really wanted to write this code here is one way to do it properly: echo "<title>" . addquote("$bbname") . addquote("$navtitle") . "</title>"; Note that my using the echo command here implies that I am IN php mode. Never left. Never re-entered. Note that I also use some space chars to help separate the pieces of that long statement. A good practice to make one's code readable to you down the road and to others who may have to work with it perhaps. And if you are not aware of it, using double quotes (") to wrap php vars is a requirement if you want them to be properly interpreted. Single quotes around the 2 vars in the above would simple give you literally $bbname and $navtitle in your html code and that is not what you want.

How exactly can someone make use of the addquote() function in a section of html markup? The solution to the problems here are not to rewrite templates, as they were working fine before the server was upgraded to php8. Quote Link to comment Share on other sites More sharing options...
ginerjm Posted April 24, 2022 Share Posted April 24, 2022 I have already asked what those addquote lines were but saw no answer. As for templates, I don't know how that could be part of this nor how they could be buried in the HTML as the OP seems to be doing. I am simply looking at some horrendous html/php mashup and trying to make it clearer to the OP. Apparently I am wrong. I'll step aside. Quote Link to comment Share on other sites More sharing options...
gizmola Posted April 24, 2022 Share Posted April 24, 2022 The first tip off in this was that somewhere in a prior post, the OP posted the name of the script that was somename.tpl.php. Next you can see from the snippets that there is pure HTML blocks, with a snippet of PHP code inside these mysterious addquote() functions, so you are of course right to have brought that up. Obviously these scripts can't possibly work as is, because the way the addquotes are used within html tags, something else had to be going on. Then we see that inside the addquote calls are small string operations that appear to be outputting various php blocks. So based on this evidence it seems likely that what is happening is that these *.tpl.php scripts are being run through a compiler which compiles them into the final php scripts that drop in and out of php frequently. Since then, of course we were able to identify that this is the forum software Discuz! which is popular in China. I found and posted links to a few threads on the official forum that state that the most current version of Discuz! is incompatible with PHP 8, for whatever reasons.

As a system admin, this issue is too hard for me. If there is no simple solution, I will have to hire a PHP programmer to do the troubleshooting. Regards, Probably a good decision. I never cease to be suprised by all the different PHP based software in use around the world, but I do think that it may be a challenge to find someone with experience in your forum that isn't a Chinese language speaker, as again, it seems primarily to be used in China. I had never heard of it before, and I've been involved with PHP development and applications for 20 years. The Discuz! forum is now owned by Tencent, and part of a suite of products offered under the "Comsenz" subsidiary. I found a few things for you that might be of benefit to whomever you work with: Main Comsenz site Here is where they advertise and sell their licensed versions Comsenz Github page Has a lot of Discuz! open source releases, but I'm not sure what parts comprise the forum. The newest release I found was December of 2020. I don't know what community this is for, but the best decision for you, if this is not a Chinese language site/community might be to look for a way to migrate to a better maintained platform. I would need to know more about your current site and community to offer better advice, but I would have serious concerns about going forward with something Discuz! based, again dependent on the answer to those questions. With that said, if you want to post for some help we do have some sub-forums that can be used for that here: https://forums.phpfreaks.com/forum/79-freelance-contracts-employment-etc/ Quote Link to comment Share on other sites More sharing options...

I am thinking to transition the forum from Discuz! to WordPress if possible. Now I am trying to find and hire a php professional from upwork. Is your server primarily a forum? Plenty of people use Wordpress, but it is not the best architected, current nor performant platform out there. It also is a blog, and has no built in forum, commerce, or other features, so for that you have to go with a plugin, and perhaps multiple companies you are keeping up with. I say this as someone who has installed, modified and supported a number of Wordpress based sites over the years. Again, if you could tell us more about the site, and what it is for, I'd have more ideas, but it might be better to go with Invision if you can afford a relatively low cost license and subscription for something that has a large installed user base and many users. See https://invisioncommunity.com/ for more information. They have a complete suite of products for communities, which can include commerce and subscriptions, and site building. This forum has used a number of different forum packages over the years and eventually settled on IPB, which we used with very little customization. Another long time commercial competitor is vBulletin, which has hosted a lot of really large internet communities over the years: https://www.vbulletin.com/ With that said, most of the original vBulletin developers created a new product, Xenforo that has a newer more modern codebase. https://xenforo.com/purchase/self-hosted For completely free/open source, there are other CMS platforms like Drupal or the Drupal 7 Fork, Backdrop CMS. They would be similar to Wordpress, only with a modern codebase, and are frequently used as an alternative to Wordpress for people who are more in need of a site building platform. Drupal: https://www.drupal.org/ Backdrop CMS: https://backdropcms.org/ There's a bunch of software you can Demo here: https://www.opensourcecms.com/forum-software/ It includes a list of other Forums that have been around for a while. I have a preference for more current codebases, but then you also take the chance that the projects will stagnate. I do think that some of the newer forums are better architected, and built upon core components like the Symfony components, that have been used in a lot of projects and have robust Unit tests and a large community of users. Along the lines of modern/different is Flarum: https://flarum.org/ I have been watching this project grow for the last couple of years, and one of the things I really like is the way they've coded around modern components, and the open source/sponsorship model. I actually created a forum with Flarum a year or so ago, and found it to be really good, but the project was scrapped. Since that time it's only gotten more mature. It is a flat thread model, driven by tags for categorization, so it might work better for certain types of communities vs. others. Flarum github here: https://github.com/flarum Good luck!
