Create a PHP form that allows input for an individual and displays the information on a subsequent page upon submission. The form should include a drop down field with each family or friend from the tree assignment and fields that match the web pages for each individual in the family or friend tree assignment. For example, fields could include career, favorite book, and interests. Use proper form validation.
Upon submission of the form, the user should be transferred to the appropriate individual's web page based upon the drop down selection. The web page of each friend or family member should now display updated results from the information entered into the form. For example, if a new goal was written in the goals field on the form, it should be appended to the goal's section of the family or friend's page.
