Say a user inputs an invalid string into a field - say for example e-mail in
a form on Page A...
Validation is done on Page B. It notices that the e-mail is incorrect and
informs the user and jumps them back to the form on Page A.
To get the values the user had input in the e-mail and other fields on the
form to re-display rather than a blank form I do the following...
On Page B I set $_SESSION('back')=1 and set other variables like
$_SESSION('name')=$name and $_SESSION('email')=$email
on returning to PageA I check if $_SESSION('back') exists and if so set the
$name and $email to the $_SESSION superglobals, if not I read the
information in from a database. I then un-register $_SESSION('back') and the
others...
There must be a better way to do this!!!!
Can anyone advise please? or point me to some text...
I dont want to get into Classes and OO stuff just yet - unless it is the
only way!
