For password check (mainly register etc) is it worth having it so that there are certain 'security' requirements, that the coder of the site sets in the user class? for example, they can set 1 if they need it to be alphanum, or 2 if they need it multicase etc? or should i just let it be anything goes?

[jacek]

let it be anything, and we can add some functions to the validate class to check for things like that. Then the developer can just use them if he wants.

[jacek]

Added two functions to the validation file for email addresses and urls. Two things which can be a pain to do well

[bowersbros]

Um, how do we use these to check if they are valid, if not say throw an error?

Im currently doing

$email = $validate->email($email);
if($email === 0){ //echo }

I feel that is wrong though.

is that what i should be doing or?

[jacek]

the validation class should be used staticly

if (validate::email($email) === false){
    // invalid email.
}

Hello,

I'm gonna try to make some kind of a form builder class. It would allow to easily create HTML forms and automatically include the appropriate validation.

I'm kind of a noob though, so it might take a while to end up with a crappy result

Regards,
CK

That could be very useful actually

Just give it your best shot, and we'll help you fix problems, or improve it and such

Yep, I'll give it a try. I'm tired of rebuilding form validation each time I make a form. There's gotta be a way to make everything easier

EDIT 1

I just found this, a PHP5 class library:
http://sourceforge.net/projects/pacl/

There are some pretty useful things in there Just have a look.

And this in case someone is interested. Some useful things in there too:
http://code.google.com/p/cmclasses/

EDIT 2

// checks to see if $haystack starts with $needle
function str_starts_with($needle, $haystack){
	$needle_len = strlen($needle);

	return ($needle_len <= strlen($haystack) && substr($haystack, 0, $needle_len) === $needle);
}

// checks to see if $haystack ends with $needle
function str_ends_with($needle, $haystack){
	$needle_len = strlen($needle);

	return ($needle_len <= strlen($haystack) && substr($haystack, -$needle_len) === $needle);
}

// checks to see if $haystack contains $needle
function str_contains($needle, $haystack){
	return (strpos($haystack, $needle) !== false);
}

Wouldn't it be easier to just use a Regex ? Would be just as easy, don't you think ? Like preg_match('#hello#',$string) would be the same as string_contains('hello',$string).

[jacek]

function str_starts_with($needle, $haystack){
    $needle = preg_quote($needle);
    return (preg_match("#^{$needle}#", $haystack) === 1);
}

Should work actually. At the time that didn't cross my mind. I would imagine that it would be slower, but will have to test.

Also, for these files it is not about doing something the easiest way, since when you use it, it is already done.

Hadn't thought about speed :/ And also, just afer I wrote that, I realised that I was building classes a little bit the same way, since it gives you the ability to change the code later without having to update applications, which is quite nice

Here are some classes I'm working on (gotta start the form class soon too ). Please tell me whether you think this is useful or not Feel free to add any of this to the BetterPHP library if you find it useful or to use this code anywhere. I don't mind

[jacek]

I will add them tomorrow, well look at them tomorrow really, looks good to me though

Great I will be updating them of course. I made these today, but still there is a lot to do. More tomorrow.

[DomC]

Hey,
If you still need it, ill be glad to help.
Although I do not know much.

Dom

[jacek]

If you have somethign to add that could be useful feel free to post it.

[DomC]

Ok, but do you have any particular requests?

[DomC]

Would some logging scripts be good?
Such as visitors, errors, 404's, hits etc.

If that's wanted i'll get started

Well, I'd personally like to see that. Could learn something from it

Looks like you have your answer to that

I have no requests but this is a community thing so, literally anything.

[Josh]

I'd suggest using the

__autoload($class_name) {
include $class_name . '.php';
}

function rather than doing that include all, including them all will slow page speed which isn't good, especially if they're not all being used.

Oh and I'd suggest you look at CodeIgniter's docs and helpers, their helpers are usually really useful (well, they were when I used CI).
