PHP Manual, look up "predefined variables". Namely those variables used for accessing variables passed from forms or URL's: the GET and POST variables.

Note: Your first if() statement is wrong. You've got an assignment instead of a comparison.

[bliss322]

aside from the first if statement being wrong (you need to use "==" instead), this is your main error:

$result=mysql_query("select * from user where username='$_REQUEST'")

$_REQUEST is generating the error. rename that variable to something not reserved (perhaps $username) and make sure you're setting it correctly prior to the sql call
