This means that those index do not exist in variable
$_REQUEST
. We have no way to know the reason. Only you can see the real contain of
$_REQUEST
with the help of
debugger.
$ins = "INSERT INTO tbl_user(uname,email,pass,gender,hobby,city,address) values ('$u','$e','$p','$g','$h','$c','$ad')";
Not a solution to your question, but another problem you have.
Never build an SQL query by concatenating strings. Sooner or later, you will do it with user inputs, and this opens door to a vulnerability named "SQL injection", it is dangerous for your database and error prone.
A single quote in a name and your program crash. If a user input a name like "Brian O'Conner" can crash your app, it is an SQL injection vulnerability, and the crash is the least of the problems, a malicious user input and it is promoted to SQL commands with all credentials.
