Hi all. I am using php sessions in an online events listing to carry around user data until all data is clean and then entering it into a database after the final form has been submitted. On the first form the user selects a category and postcode, and the processing script validates and cleans these fields and passes them into corresponding session variables, same for 3 more forms. All works like a dream - until now. Now the user enters the category and postcode, goes to the next form, and the variables are not there in the session. I am var_dumping the session at the top of each page to track the behaviour to see what is happening and it only occurs here - when the user goes back one page in each case their previously entered values are there (as I echo the session variable in the fields), but not in the session array. Has anyone encountered this kind of problem with sessions before? -- http://www.web-buddha.co.uk http://www.projectkarma.co.uk
