So i'm making a browser based instant messenger using javascript and PHP.
There is a form on the page which sends the message to a MySQL database using the POST method.
Upon loading the page to write messages, the user is prompted to enter a username which is then held in a js variable. Now I figured out that you can't transfer the contents of a js var to a PHP var, so instead I have been trying to have the page write the value of the username var to a hidden textbox on the form.
I can make the js write the value of "nickname" to the textbox, but when I submit the form: "Undefined index: nickname in C:\wamp\www\new\insert.php on line 11".
I don't understand this though: the column is part of the mysql table it adds the data to, it was not doing before I worked out how to add the value of the variable to the text field on the form.
This is the "Chat.php" that the form is on.
This is the insert.php which adds the data to the table.
If you need any more information, just ask.
Thank you for any help, fellow TPU members!
