Error Checking, Storing and Showing

[sniko]

Overview

In this tutorial you will learn how to easily display and store errors throughout your code (this will become clear later on), this is a vert fast process and very good when using if's and else's.

 

We store the errors in an array and then display the ones which are needed.

Level: Fairly Easy

 

1) Create the array

$errors = array();

 

2) Add error to array

$errors[] = "bla";

 

3) Display the error

	if(isset($errors) AND count($errors) > 0)
	{
		echo "<h3 class='error'>". count($errors) ." errors occured!</h3>";
		foreach($errors as $msg)
			{									
				echo $start.')'. $msg .'
';
			}
	}

 

Usage

You could use it anywhere necessary, for example on a register page. (see below)

 

	$errors = array();

	//loginname
	if(strlen($loginname) < 5)
		{
			$errors[] = "Please make sure your login name is more than 5 characters in length!";
		}
	if(strlen($loginname) > 15)
		{
			$errors[] = "Please make sure your login name is less than 15 characters in length!";
		}

 

If you have any questions about this method, please reply in this topic.
