PHP 7.2 issue - Parameter must be an array or an object that implements Countable

[tyler-deboer]

I'm getting a PHP error any time I try saving an entry with a Button Box field.

count(): Parameter must be an array or an object that implements Countable

The error says it's happening on Line 226 of vendor/craftcms/cms/src/fields/BaseOptionsField. Since the error is happening in the Craft vendor package, it may be something that has to be fixed in Craft itself? Or is that something that can be addressed in the plugin?

Interestingly enough, when I switched my MAMP environment from PHP 7.2 to PHP 7.1, the problem went away and I was able to save things correctly. So it seems to be a 7.2-specific issue.

PHP Version: 7.2.1
Craft Version: Craft Solo 3.0.3.1
Button Box Version: 2.0.0

Same issue here while using button box in a matrix or NEO field.

count(): Parameter must be an array or an object that implements Countable

PHP 7.2.1
Craft Pro 3.0.9
Button box 2.0.0

@tyler-deboer @E2design I have just tested this using PHP 7.2.6 and Craft 3.0.9 and it all worked fine regardless of whether it is inside a Matrix or on its own.

Could you please confirm if you are still getting the error?

We just ran into this on Craft 3.0.10.2 & PHP 7.2.6 - so this is still an issue.

Downgrading the project to PHP 7 resolved it for now.

Issue still persists

@chasegiunta @E2design I have released a new version of the plugin which should fix this issue.

Still having this issue. Any thoughts?
Craft CMS 3.0.15
PHP 7.2.1
Button Box 2.0.1

Can confirm dropping down to PHP 7.1 fixes the issue.

Looks like the updates made to Colours.php need to be made to Buttons.php as well.

[E2design]

Still having the issues

PHP 7.2.7
Craft 3.0.15
Button box 2.01

@jeffaglenn @E2design Thank you for reporting this. I have fixed count error for Buttons, Text Size and Width field types. Please downloaded the latest version 2.0.2 :)
