mattennant Posted March 26, 2005 Share Posted March 26, 2005 hello i'm trying to create a page where a user enters a name and password into the database. After inserting the users name is passed as a session variable to a thankyou page. I've got no problems passing a session variable from a standard form (i.e not an insert record) but when i try and retrieve the session variable after inserting these user details nothing appears. here's hoping someone has the answer. thanks mat Quote Link to comment Share on other sites More sharing options...

mananthpai Posted April 19, 2005 Share Posted April 19, 2005 Hi there you have to put the header's before any output to the browsers even space should not be there in ur code so you have to write <?php session_start()?> in the very first line of ur code page and there should not be any sapce before this line try this out this might fix ur problem Quote Link to comment Share on other sites More sharing options...
