$_Post data returns blank Ajax - php

Question

I have a form. I would like to get the input information and send it to the database via 'update_user_meta', however $_POST['this-user'] is giving a blank entry in the database.
The '$user_id' and '$meta_key' are posting to the database but the '$meta_value' is blank.
When I console log $_POST through ajax I get a blank entry in console. When I run .val() in jQuery I also get a blank entry not undefined or NULL.
I have tried having the data section of the code be
data: {
'action': 'hide_this',
'this-user': this-user,
'hidebtn2': hidebtn2
},
However a dash can't be in function i.e 'function doAjaxRequest4(hidebtn2,this-user)' is not allowed.
Insight is appreciated.
