What I think you are asking is how to combine a POST method with a GET
method in order to chain the processing of a form across multiple php
files. That is: the action from the form (assuming the method is POST)
will post the form variables to the first php file (named in the
action). After you do the isset, you then want to pass control to the
second php file for further processing.
If so, there are a number of ways to accomplish this but the two
simplest are:
1. call the second php file using a GET method. That is: use the calling
form of second.php?var1=val1&var2=val2... As you can see, this will
expose the values for var1, var2, etc.
2. use the SESSION mechanism to pass the values to the second php file.
This involves writing the values to the session and then using the
header to call second.php. Second.php must use the session to read back
the values it is expecting.
Most other ways involve the use of temporary storage in a disk file,
database table or shared memory segment. These are less efficient and
more complex to set up.
