PHP Forms Class in Action

A couple of days ago I created a Forms class that I can re-use in most of my projects. I stated that I would show you an example of how I generate the form fields when they're needed. So here we go.

To reference the Form Class:
http://dinocajic.blogspot.com/2015/06/php-forms-class.html

In the following example I'm creating a form and utilizing the forms class to help me separate most of the HTML from PHP.

This is what the form will look like once the code is executed.
















To help guide you through the code:

  • $_form is instantiated prior to the method call. 
  • A random token is generated and set to $_SESSION['token'] to prevent Cross Site Request Forgery
  • Also as an additional measure of security, we're only going to allow for the form to be valid for 5 minutes. So, we'll set $_SESSION['token_time'] = current time()
  • The hidden field is generated with the random token as the value
  • Input type of text is called to generate po_number..
  • Months are generated (i.e. 1 => January, 2 => February, etc).
  • Select tag is generated and the months are passed into it as the options
  • Days are simply generated as 1 to 31 and are passed to a new select tag
  • Two years are added to the current year and are passed to another select tag.
  • Locations are passed through to a select tag. This ideally should be stored in the Database but for the sake of the example, we added the locations manually to the array before passing it to the select tag
  • Status array is generated (another good example of items that should have been stored in the database) and passed to another select tag.
  • Submit button is generated
  • Form is ended.
  • Also please note that the form() method is part of a class. I just created a snippet so that you can focus on the method() itself



Later, I'll generate a class that ties all of it together.

Beginner Java Exercise: Sentinel Values and Do-While Loops

In my previous post on while loops, we used a loop-continuation-condition to test the arguments. In this example, we'll loop at a sentinel-controlled loop. The sentinel value is a special input value that tests the condition within the while loop. To jump right to it, we'll test if an int variable is not equal to 0. The data != 0 within the while (data != 0) { ... } is the sentinel-controlled-condition. In the following example, we'll keep adding an integer to itself until the user enters 0. Once the user enters 0, the loop will break and the user will be displayed with the sum of all of the integers that he/she has entered. As you can see from the code above, the code is somewhat redundant. It asks the user to enter an integer twice: Once before the loop begins, and an x amount of times within the loop (until the user enters 0). A better approach would be through a do-while loop. In a do-while loop, you "do" something "while" the condition

Programming Language Concepts Test Questions/Answers

One of the easiest methods that I use to learn new topics is by creating notes on the subject and then by turning those notes into questions and answers. Remembering answers to questions just seems more natural. I was able to memorize 323 questions and answers in a matter of a couple of days. I wanted to start doing this for some topics that I find pretty interesting. To begin, here are some questions and answers to Programming Language Concepts (PLC). I'm reading your mind right now and the answer is yes, there will be more. 1. Name 3 reasons for studying PLC. - Better understanding of current programming languages - Advancement of computing - Increased capability to express ideas - Increased capability to learn new programming language. - Better understanding of which programming language to choose.  2. Name the 5 programming domains and languages best suited for each. - Scientific (Fortran, ALGOL 60) - Business (COBOL) - AI (Lisp, Scheme, Prolog) - Web (PHP,

Creating your own ArrayList in Java

Wanted to show that certain data structures in Java can be created by you. In this example, we'll go ahead and create an ArrayList data structure that has some of the methods that the built in ArrayList class has. We'll create 2 constructors: The default constructor that creates an ArrayList with a default size of 10. Constructor that allows an initial size to be passed to the array. We'll also create a number of methods: void add(Object x);  A method that allows you to place an Object at the end of the ArrayList. void add(int index, Object x);  A method that allows you to place a value at a given location. Object get(int index):  Allows you to retrieve a value of the arrayList array from a given location. int size();  Allows you to get the number of elements currently in the Arraylist. boolean isEmpty();  Tests to see if the Arraylist is empty. boolean isIn(Object x);  A method that sees if a particular object exist in the arrayList. int find(Object x);
