I am just starting work on editing a PHP script that someone else in
the company wrote. I noticed that this person chose to use different
PHP pages depending on the error. For instance, the main form contains
input boxes for Name, Address, Telephone and Email. When submitted, the
form calls a file called verify_email.php. This file runs an if/then
statement. If the email is valid it calls another form, such as
verify_name and so on until everything is validated and the information
is written to the database. If the email is invalid, it displays a new
form which is similar to the original form, only this one has the email
box highlighted in red and asks the user to enter the email again. All
the input boxes are already filled in as the coder chose to use PHP
variables to re-enter the information for the customer, instead of
having to start over.
The question I have is, is this an "acceptable" way to handle error
messages. Being quite new to PHP I don't know what to make of this
method.
