InputfieldCKEditor.module Error

[kaz]

PHP 8.3
ProcessWire 3.0.229

I get this error message in the CK Editor when I select a page for editing:

Deprecated: trim(): Passing null to parameter #1 ($string) of type string is deprecated in /Users/username/Sites/project.com/wire/modules/Inputfield/InputfieldCKEditor/InputfieldCKEditor.module on line 205

How do I get rid of this message?

So you go on an admin page that contains a CKEditor and you get this error?
Do you have some hooks that target CKEditor, or some special configuration for the CKEditor? Plugins, other modules that interact with it?...

The code that triggers this error is:

	public function set($key, $value) {
	
		// convert extraPlugins string to array
		// used to be stored as a string in older versions
		if($key == 'extraPlugins' && is_string($value)) {
			$value = str_replace(' ', '', $value); 
			$value = explode(',', $value); 
		} else if($key == 'extraAllowedContent') {
			$value = str_replace(array("\r\n", "\n"), "; ", trim($value)); // trim() here receives a null value
		} else if($key == 'configName') {
			$this->configName = $value;
		}
		
		return parent::set($key, $value); 
	}

So this error happens when using "extraAllowedContent" and passing null as value.

What you could do is editing this code and add a throw and look at the stacktrace to see what is calling this function with a null value (if $config->debug = true stack trace is directly shown on page):

	public function set($key, $value) {
	
		// convert extraPlugins string to array
		// used to be stored as a string in older versions
		if($key == 'extraPlugins' && is_string($value)) {
			$value = str_replace(' ', '', $value); 
			$value = explode(',', $value); 
		} else if($key == 'extraAllowedContent') {
			$value = str_replace(array("\r\n", "\n"), "; ", trim($value)); // trim() here receives a null value
            if ($value === null) throw new Exception('Check the stack trace!'); // trigger stack trace
		} else if($key == 'configName') {
			$this->configName = $value;
		}
		
		return parent::set($key, $value); 
	}

@da² Yes, I edit pages in the admin area. In the template I have a textarea field / CKEditor.
I don't have hooks for the editor. I have custom styles, saved in the CKEditor field > extraAllowedContent. The styles are displayed and works fine. I think that's not the problem.

/site/templates/assets/ckeditor/ckeditor.css
ckeditor:/site/templates/assets/ckeditor/ckeditor.js

With a change of the 'public function set($key, $value) …' code I get the same error message, it makes no difference. I cleared the cache, what else can I do?

What more? config: I added own styles to the editor which change the appearance of the RepeaterMatrix links. RepeaterMatrix links doesn't look very nice, so I set them as buttons. No big deal, just CSS, no JS or PHP.

$config->styles->add($config->urls->templates . 'assets/css/admin.css');

I activated and deactivated the ACF settings ... the error message remains. When I delete the field and create a new one, will I probably lose all entries from the database?

Do you still have the warning when removing this styles?

@da² I removed the entries in the field. The error message remains.
