Also, instead of:
“if (d > DateTime.Now) { return false; } else { return true; }”

You can just say:
“return (d <= DateTime.Now);"

While using GET method all the submitted data is displayed in the address bar. You notice that information which is displayed after “?”, will be something like that:

http://domain.com/script.php?name1=value1&name2=value2

It can be useful, where you want to bookmark a page with some specific query string values. However, the GET method is limited by the URL length (2083 characters in Internet Explorer according to Microsoft) and every of the input values must not override 100 chars. May be you also don’t want to provide GET method because of submitting important data like passwords, etc, it will be displayed in the address bar.

The POST method has possibility of much volume data sending (usually by the server settings limited) and it may be used unless it represents benefits in comparing GET method. A lot of browser can not correctly bookmark pages which are displayed after HTTP POST method, because the submitted data is displayed in the address bar.
When you need the query string, which is get by GET method using (ineffective by it’s limits), you will try to use POST method for your forms. You can use POST method if you submit the important information which shouldn’t be displayed in the address bar.

if (defined $mystring and $mystring eq ”) {
#string is empty
}

I think we need more info to help you. Are you trying to upload a file or are you wanting to create a file on the fly to store info?

That will give an warning if $mystring is undefined.

if($mystring)

That doesn’t check if $mystring is defined. It checks that it is true. For example the number 0 and the empty string are defined values that are false.

Why not just use the “defined” function?

In the autoload.php in codeigniter, you can put the form helper in the autoload array for helpers.

I agree that codeigniter is very easy to learn, but the fact I was talking was the learning curve associated with any MVC framework when you come from a traditional coding background.
