Hi @justintylermoore
$_POST[‘acf’] is an array, so if you join it with a string, it will show up as “Array”. You need to access the data inside the Array. An easy way to check the data is by using the var_dump() function. This page should give you more idea about it: https://www.advancedcustomfields.com/resources/debug/.
To learn more about the Array type, please take a look at this page: http://php.net/manual/en/language.types.array.php.
I hope this helps.
