if statement and mkdir within luser register script

[wrathican]

hey i have a problem with a register script.
what i want to happen is when a user submits their information and the registration is successful, a directory under their name is created in a specific location.

i assume you can do this using a if statement. so i have created the following one:
[code]$userdir=$_POST['user'];

if($q=success)
{
mkdir("/htdocs/images/gallery/".$userdir, 0777);
}[/code]

if your wondering what $q is, its this:
[code]$q = "INSERT INTO users VALUES ('$username', '$password')";[/code]

when i load up the page i get this warning:
[quote]Warning: mkdir(): open_basedir restriction in effect. File(/htdocs/images/gallery/) is not within the allowed path(s): (/tmp:/usr/share/pear:/home/fhlinux178/g/gallery.ls12style.co.uk/user) in /home/fhlinux178/g/gallery.ls12style.co.uk/user/htdocs/register.php on line 34[/quote]

your help is greatly appreciated

This means that your host has a restriction in place to only allow writing in certain directories.

You should be able to contact your host to find out where you can create directories.

Look [url=http://uk2.php.net/features.safe-mode]here[/url] for further details

You might try...

[code=php:0]
mkdir($_SERVER['DOCUMENT_ROOT']."/images/gallery/".$userdir, 0777);
[/code]

/htdocs doesn't look right.

hey thorpe thanks
the code you suggested definately did something right.
the error message has changed from the above to this:
[quote]Warning: mkdir(/home/fhlinux178/g/gallery.ls12style.co.uk/user/htdocs/images/gallery/): File exists in /home/fhlinux178/g/gallery.ls12style.co.uk/user/htdocs/register.php on line 34

well i have figured out why i get that error message. its because the initial directories have already been created. when running the script it creates the folder that i want, but it still displays the error.  ???
  >:(
i want it so that it doesnt display the error.

another problem is that from testing it when i come to clean up the mess i made, i cannot delete the folders because i didnt create them. the script did. does this mean i have to use a script to delete them?

use file_exists() to check and see if the folder exists first before you create it.
[code]<?php
if(!file_exists($folder)){
mkdir($_SERVER['DOCUMENT_ROOT']."/images/gallery/".$userdir, 0777);
} else {
echo "Folder already exists";
}
?>[/code]

hey ray, thanks for your help, but that is not my problem.
if i am reading that code right, it is only creating the directory if it doesnt exist in the first place.
but what i want is a piece of code that creates a folder in that directory everytime a user registers with my website.
but only if the registration is sucessful.
would i be better off sending the variable to another php file in that directory with the mk dir function?

I happen to be working on a site that does just what you want.  I'll go ahead a post a piece of my registration script, it's 100% working.
also note that there's no implemented security such as add_slashes() and whatnot, don't forget to add that.
func.php

[code]
function set_dir($user)
{
$path="users";
$newdir="$path/$user";
mkdir($newdir, 0777);
}


function register_new($username, $password, $passwordb, $email, $terms)
{
$check=@mysql_query("select username, email from filehost_users");
while($row=mysql_fetch_array($check))
{
if($row[0]==$username)
{
$regp=1;
$_SESSION['error'].="<p>That username is already taken.</p>";
}

if($row[1]==$email)
{
$regp=1;
$_SESSION['error'].="<p>That email is already in use by another account.</p>";
}
}
if(!$username)
{
$regp=1;
$_SESSION['error'].="<p>You must specify a username.</p>";
}
if(!$password)
{
$regp=1;
$_SESSION['error'].="<p>You must enter a password.</p>";
}
if(!$email)
{
$regp=1;
$_SESSION['error'].="<p>You must enter an email address.</p>";
}
if($password != $passwordb)
{
$regp=1;
$_SESSION['error'].="<p>The passwords entered do not match.</p>";
}
if(!$terms)
{
$regp=1;
$_SESSION['error'].="<p>You must agree to the Terms & Conditions.</p>";
}

if($regp==1)
{
header("Location: $_SESSION[url]?loc=register");
exit();
}

$register=@mysql_query("insert into filehost_users (username, password, email) values ('$username', PASSWORD('$password'), '$email')");
set_dir($username);
return $register;
}
