PHP: Get input box value
Hi I am trying to see if a username is already taken in my table.
The following code calls the Java function when the user clicks out of the textbox.. It works great but I have to manually enter a username where it says 'HERE!?'
I would like it to use the value of the textbox 'text'.
How would I go about doing this?

completely wrong approach. PHP is executed on the server before the HTML/JS is displayed in the browser.
hence you cannot mix JS and PHP like that.
what you can do is ask a PHP script via AJAX, whether a certain username exists. and of course the DB table needs to be unique on the username field.
