Often overlooked, super simple.
The name attribute needs to allow for multiple selections to be sent over
$_POSTas an array. For example:Notice the
[]in the name:name="my_meta_box_select[]"This, alongside the
multipleattribute, will allow your$_POSTvariable to contain all selections as an array. That said,$_POST['my_meta_box_select']will not just be a simple value, but rather will be an array will all selections.
