ITC280 Update 10

What I learned in Week 10 of the ITC280 Class:

1) Here is how we create a session variable in PHP

if(!isset($_SESSION)){session_start();}


$sCustomerID = trim($row['CustomerID']); //Grab the Customer's unique ID, from a database


$_SESSION["sCustomerID"] = $sCustomerID; //Enter variable into session variable


2) We can clear a session by calling:
session_destroy();


3) To clear the data before destroying a session; insert an empty array:
$_SESSION = array();//copy empty array in case of failure!


4) We can silence notices and warnings by placing this code on our file
error_reporting(E_ERROR | E_PARSE); //only major problems

5) We can check the contents of the session and if the session is not set, we can send the user to a login page

if(!isset($_SESSION)){session_start();}
if(!isset($_SESSION['sCustomerID']))
{ //no session var
     myRedirect("login.php?msg=5"); //send user back to login page, as session has timed out
}

6) To find and upload setting, view the PHP info command results and search for the string via the browser. For example;

upload_max_filesize


7) To be able to upload a file, we need to use the enctype attribute in our form.

<form action="upload_test.php" method="post" enctype="multipart/form-data">


8) We use the file attribute of the input element to allow a file upload.
Please select an image to test upload: <input type="file" name="image" />

NOTES:
Seriously, did I finished the final project? My teacher said that this assignment served as the last part of my final project. I really don't know why. I haven't made a project before, but let's face it. I should accept the fact that my teacher said I already finished my final project. As I recall, my teacher said that Assignments 8 to 12 served as part of the final project. Really? If I said yes, then it is. That means I done it. Question is, should I come to class on Monday and Wednesday? I should remember that next week is the last week of the Spring 2012 semester.

Never mind, I'll find out by myself.

That is all.
