Fatal error: Cannot use $this as parameter

gomedia · 2020-11-03 11:43:43

I’m getting the following error:

Fatal error: Cannot use $this as parameter in /home/grampia1/public_html/textpattern/lib/txplib_misc.php(1870) : eval()'d code on line 716

I’m trying to transfer a website from Mac to Live hosting.

I can set up a vanilla TXP website on the live hosting but when I copy across the local files & database dump file, restore it using phpMyAdmin, then refresh TXP admin the above error is generated.

Any thoughts?

Would it be caused by a plugin? Is the error still present when all plugins are off?

Hi Yiannis, thanks for the reply.

It looks like it’s a PHP version issue. Changed the online version to match my local version and … phew!

Hi both,

this looks like coming from eval(), but in 4.8 we only use it in <txp:php /> tag, please check if you have any. Before 4.8 we eval’d plugins code too, so Yiannis could be right.

Edit: for the record.

Thanks guys. Have found a couple of plugins that use $this as a variable but there’s nothing obvious as to why it would be a problem in PHP 7.2.34 but not in 5.6.40.

Cheers,

Adi

It is indeed strange as I am using plugins using $this on PHP version 7.4.10 without any issues.

rah_external_output 1.0.4 (I know it is no longer needed but I am too lazy to find all instances in other sites)
ied_plugin_composer 1.2.1
oui_cookie 1.0.0-Beta4
com_connect 4.7
rss_admin_db_manager 4.6

Seemingly the switch has been operated in php 7.1.

$this is not deprecated, only its behavior in certain constructions is.
