Here's the scenario...
I am building a site in which users will be able to create and then later
edit personal information. When they edit their information, I need to keep
track of what was changed so that I can inform via email a person to
approve the changes. Here's the flow I'm considering...
When an UPDATE page is loaded, I build an array like...
$fields = array("table.field1" => value, "table.field2" => value,
"table.field3" => value)
I then plan to save this array to a SESSION variable. Then, when the form
is posted I save the new form contents to another SESSION variable. Then I
compare the two arrays and save the names of the fields changed to an array
saved in a third SESSION variable. Finally, when I build the email, I can
parse the changed fields array to inform the person who must approve the
changes.
First, does anyone have a suggestion of a better way to do this? Second, I
can't seem to save an array to a SESSION variable. I build the array in a
local variable and then set the SESSION variable equal to it. When I recall
the SESSION varialbe, it's contents is "Array". Then, when I print_r() the
SESSION variable, I still get "Array" as the contents. What's up?
Thanx in advance for any help.
