PHP Tutorial - 29 - Checking Username for Game

[Ric0tjuh24]

btw correct if statement is: if(!eregi("[^A-Za-z0-9]",$test­) ... boston fails to nest his ( and ) right

[B1KMusic]

@Ric0tjuh24 you have three parentheses, that makes no sense. It goes

if ( !eregi ( "[^A-Za-z0-9]", $test ) )

[Ric0tjuh24]

NOOO for the 10th time, your source code is NOT on the site! shame

[pkiriakou]

This function has been DEPRECATED as of PHP 5.3.0. Relying on this feature is highly discouraged.

[iceboarderz]

Hey. Just wanna say that I think that your code segment is incorrect. The one that checks if the username is alphanumeric.

[th2]

great vid

[Computerwizgeek920]

alphanumeric =3

[SnijdersMax]

EXTREMELY IMPORTANT!!! REPLACE the whole !eregi...... function with this,

so the statement looks like:

if(!preg_match('/[^A-Za-z0-9]/­i' , $test)){

statements.....

}

@SnijdersMax can you please explain me why ^^

thank you very much!

[SnijdersMax]

@lpperalta1

This is becuase eregi() is deprecated in newer versions of PHP, so it's wiser to use the function preg_match because that one will stay around longer...in other words, if you upgrade your php version, eregi() won't work anymore. If you want your php scripts to be flexible and not crash after you updated php, this is the way to go

[lpperalta1]

@SnijdersMax Thank you so much again



[SnijdersMax]

It took me a long time to figure that out, so i figured i'd just share it here

[lezahann]

i can't find the source code in your site :(

[beatboxpeej]

Wow on the embarassing part...just wow.

[lance182]

awesome but u shouldve just called the variable usernametest

[coolcam262]

your voice keeps changing...

[Niel8181]

@coolcam262 Would be boring if he keeps the same tone for 10 minutes,

just like my teacher.

[xbugster]

why let the people click and click and click if errors appears in form.

isn't better to check username availability with ajax on blur? i am sure is much better.

[xbugster]

@xbugster I also want to warn guys who just learning to not use eregi anymore because is deprecated from php 5.3.0. use preg_match()

[TheEgao]

Bucky, where is this forum???!!! To tell you the truth i can find it on your web page.... i would appreciate it if you could tell me :) btw nice tutotrials :) ^_^

[TheTamasPataky]

Hi! Great tutorials thanks heaps ...

just a quick comment: the ereg expression is deprecated and removed from recent php versions use preg_match instead

[relysaa]

There's an error in the video:

have a look at the position of the first closing bracket.

correct is:

if(!eregi("([^A-Za-z0-9])",$te­st))

[beatboxpeej]

@relysaa Also. $_POST[username] should be $_POST['username'] if I'm correct.
