Displaying Errors and Redirecting a Form
There is a form that has a required field.
When the user clicks the "Submit" button...
1.) If the required field was left blank, then the form should re-appear with a warning message next to the omitted field stating, ERROR: Field must contain a value.
2.) If the form was filled out correctly, then the form should re-direct to another page (which is the next step in whatever process).
If so, what would the PHP code look like?
