Blank mutliselect fields after selecting actions or filters --ereg() deprecated PHP7.0..

[XPERTPCNET]

When adding a Webhook, no fields items are displaying after selecting actions or filters .

The following error is logged:

PHP Fatal error: Uncaught Error: Call to undefined function ereg() in /path/wp-content/plugins/hookpress/services.php:13

Two possible solutions:

Solution 1
// changing the deprecated ereg() function to mb_ereg()
from: if (ereg('[A-Z]+',$arg))
to: if (mb_ereg('[A-Z]+',$arg))

Solution 2 (seems to be more recommended):

// changing the deprecated ereg() function to preg_match()
from: if (ereg('[A-Z]+',$arg))
to: if (preg_match('/[A-Z]+/',$arg))
