Alteration to php code required

I have 2 files [login to view URL] and [login to view URL] There are 2 sets of tasks to be performed _**TASK 1**_ There are 2 text boxes called email and confirm email in the [login to view URL] file. I want the value to be as is now and also I want the user to be able to change the values if he wishes to ( as is now). However, when user clicks submit and the [login to view URL] file is called, I want to check what email address is entered by user. if it is blank or if it is the default value as seen in hard code value of the text box it has to be changed to the users actual firstnamelastname@[login to view URL] and enter that into the database. _**TASK 2**_ Right now when user signs up the Id that is created is also entered in service_provider and business tables in addition to what is populated in the userprofile table and that is good , but I also want the ID for each record from userprofile to be captured and entered into the ServiceProviderID field of the userprofile table if service provider type is picked i the signup.php. If business is picked the businessid field in the userprofile table has to be populated with the id. Everything else is working just fine
