php codes

The following video is done through MAMP.
The PHP processes can also be done by uploading to your provided remote folders.
However, the database work does require MAMP/WAMP - Download and instructions here
*This is not required, but you are welcome to try

Part 2

• Objectives:
  • Discuss how php works
  • Using MAMP to emulate a server and database
  • Work through some examples of php to demonstrate how information is passed
    • Get
    • Post
    • Cookies
    • Database
  • Demonstrate the structure of a home made content management system
• Here is some php code to get you started...
  *Note...This section of class is very buggy. Consider it a lecture demonstration but follow along as best you can.
  • PHP info - supplies information such as which php version is being used and what attributes are turned on
    
    • <?php
      // Show all information, defaults to INFO_ALL
      phpinfo();
      ?>
    • Note* To test this code for yourself, please install MAMP or WAMP
    • * To use a database wizard you will need to download a depricated extension into Dreamweaver:
      Server Behaviors and Database
  • Php is a dynamic language...which means that information is passed based on a users actions. Otherwise the pages are static and unchangable.
  • There are different ways to pass information to other pages - which means there has to be a method of storing the information
    • Passing information through the URL (the get method in forms)
    • Using a post method in forms that passes hidden information
    • Setting Cookies
    • Sending information to a database

  • Passing information through the URL
    • On the original page add ?variablename=result
    • ex: animalpage.php?mypet=Cat
  • On the second page to fill in the approriate area with
    • <?php echo $_GET['mypet']; ?>
  • Here's how it works
