Fatal Error with implode() in [give_totals] Shortcode Rendering

[rafacrt]

I encountered a fatal error when using the [give_totals] shortcode due to the improper use of implode() within the give_totals.php file. The error occurs when implode() is called on a variable that is not consistently an array, which causes issues in PHP 8 and above.

Error Message:
Fatal error: Uncaught TypeError: implode(): Argument #2 ($array) must be of type array, string given...
File and Line: give_totals.php within the Give Totals widget.

Solution: To resolve this issue, please ensure that the variable being passed to implode() is an array. Here’s a suggested fix to check if the variable is an array before using implode:

// Check if 'ids' is an array before applying implode if (is_array($attributes['ids'])) { $ids = implode(',', $attributes['ids']); } else { $ids = $attributes['ids']; }

Alternatively, this can be handled with a simple fallback in case ids is a string:

$ids = is_array($attributes['ids']) ? implode(',', $attributes['ids']) : $attributes['ids'];

This fix should prevent compatibility issues with PHP 8+.

Environment:
PHP Version: 8.3
GiveWP Version: 2.0.1
WordPress Version: 6.6.2

PHP Version Note:

It's worth mentioning that this error does not occur in PHP 7.4 because it does not enforce strict typing in the same way as PHP 8+. Downgrading to PHP 7.4 can temporarily bypass the issue; however, PHP 7.4 reached its end of active support

Please let me know if further details are needed, and thank you for your attention to this issue!
