I have a multiselect drop-down field called “holds”.
When nothing is selected, the holds name does not show up in $_POST
The only fields that display in the $_POST array are fields that are selected or have data in the text field.
How do I force $_POST to list all input fields (whether they contain data or not)?
If the browser doesn’t send the value to the server,
$_POSTwon’t contain it. Period.
