I am trying to add a <input type="file" ... > to wordpress custom control for customizer. I have it displaying the browse button but when you select a file it does not register as being modified and that means it does not change the publish button to allow the submit. I need the file to be read as plain text exactly like a regular text box but using the browse button and selecting the text file. I do not want the file to be uploaded to the upload directory only read exactly the same as a text box. I assume I need a jquery or something to fix this to make the selection allow the submit?
