Hi! We have created a system plugin (Joomla 4, PHP 8.0) to manipulate the article title. We discovered that this system plgun causes issues when JCE is uploading a file. We get this error: "The server returned an invalid JSON response."

We can solve this issue by making a change to the system plugin:

function onContentBeforeSave($context, &$article, $isNew, $data)

When we remove the $data variable, there are no issues. So this $data variable is causing the upload issue.

I am not sure why this is happening. The system plugin should not affect the JCE file upl;oad. Correct?

in the Joomal docs I read this regarding the $data parameter of onContentBeforeSave:

+++++
data: The data to save. Note this data should be already validated by the extension. Since Joomla 3.7. Required to be set by extensions as of Joomla 4.0 as the core joomla content plugin uses this property
+++++

Any thoughts? Should I just leave the $data variable out or should JCE handle this differently?

Kind regards,
Jip

Hi Ryan, yes that works. But I do wonder if maybe other extensions we will be using (in the future) will also cause issues when they don't use this variable. Should every extention (like JCE) that uses onContentBeforeSave create a $data variable or should plugin creators always use $data = array() to create this data varaible when it is not passed by the extenison?

Anyway, I al leat now know how and what. The system plugin works and JCE upload also. So thanks!

Thanks Ryan!
