hello dear PHP-Fans - greetings to you - and a happy new year!!


i set up a WAMP-System on my openSuse 11.4 system.  In order to learn as much as i can bout PHP i want to do some tests and write some scripts.

Well the WAMP is allready up and running.  Now i try to give the writing access to the folder

mkdir /srv/www/

where the php-scripts should go in...

i want  to give write permission to all to all files in /srv/www

As root I generally:

mkdir /srv/www/
chown <webmaster usrername> /srv/www/

/srv/www/ should be readable and traversable by all, but only writeable by it's owner (the user designated as the webmaster.)

can i do this like mentioned above,...

Love to hear from you

greetings

		header("Location: index.php");
		
	} else if($_SESSION['user_level'] == -1) {

		die();
		header("Location: banned.php");

	} else if($_SESSION['user_level'] < -1) {
		die();
		echo "An error has occurred please contact your administrator.";

	} else if($_SESSION['user_level'] == 1) {
		$_SESSION['username'];
		$_SESSION['password'];
		header("Location: admin.php");

	}


}

Hi all

I have been looking though loads of tutorials regarding log in method for websites (not APIs), and cant help find that they are outdated.

So I am asking what is the correct way to create a log in system using php?

Modern websites use JavaScript for asynchronous web requests so this requirement should also be catered for. APIs and mobile apps use access tokens which is very secure if implemented correctly.

Can we use the token principle for websites? As the way I see it that most php log in systems use php sessions and they create a session and save some data in this session when the user successfully authenticates, however the session id is held in a cookie so if the cookie is stolen then they have access to your account.

API access tokens are expired and refreshed periodically so is there such a implementation method for web sites too?

i am trying to add a like system to my forum similar to facebook where it shows how many people like a post.

this is my code so far:

$like_list = "";
            
            $likes = explode("|", $post_info['post_likes']);
            $amount_likes = count($likes);
            $ac_likes = ($amount_likes / 2);
            $slice = array_slice($likes, 0, 4, true);
            $remain = array_slice($likes, 4, $ac_likes, true);
            $remain_num = count($remain);
            
            if ($ac_likes >= 4)
            {
                for($i=0; $i<$ac_likes; $i+=2)
                {
                    $like_list .= $likes[$i].", ";
                }
                $like_list .= " and $remain_num others like this";
            }
            elseif ($amount_likes == 1    )
            {
                $like_list .= "0 people like this";
            }
            elseif ($ac_likes == 1)
            {
                $like_list = implode(", ", $likes);
                $like_list .= " likes this";
            }
            else
            {
                $like_list = implode(", ", $likes);
                $like_list .= " like this";
            }

$post_info['post_likes'] contains data like:

Code: [Select]
user1|123456789|user2|123456789
where the number is the timestamp.

unfortunatly $like_list prints the username and the timestamp when i would like it to only display the username. This means
printing every 2nd element in the array starting from 0. I have seen this done with for loops but i am not using one therefore i am stuck. Any ideas? and is this the best database setup for likes? the post_likes column is added on to the end of the post table.

Hi All

I am wanting to create an online booking system. Has anyone got any suggestions on this?

Hi Everyone,

Just a quick question before I take on this project.

Basically the client has a secure server set up with folders for different clients. So they can store excel files, PDFs etc, What the client use to do was send the client an email with the http address of that clients particular folder to be able to login.

What my job is to create a login system that redirects each client to their particular area on the secure system.

Is this going to be difficult,

What I was thinking of doing was when the administator is setting up the client details there would be an extra field saying address: they paste the address of the folder on the server. Then it will redirect them to their folder.

Is this the correct way to do this.

Any help or advice would be great.

I'm busy with a small storage system for my site, but i encounter some problems with it.
I have successfully managed to get all products from the order, and traced on what spots those product are in the warehouse.
It looks like this atm http://img37.imageshack.us/img37/7302/tableordereng.jpg

this is the code i have atm (sorry i program in dutch, i hope its abit understandable)

Code: [Select]
<?php

$query = "select * from `orderregel` WHERE `ordernr`='".$ordernr."'";
   $row = mysql_fetch_array( $query );
            
   echo "<table border=1 width=680 bgcolor=#FFFFFF>
     <tr>
            <th width= 100>artikelnummer</th>
        <th width= 100>productnaam</th>
            <th width= 40>Plaats</th>
        <th width= 40>aantal in magazijn</th>
            <th width= 40>aantal nodig</th>          
     </tr>
         </table>";  
                      
            foreach ( self::find_by_sql($query) as $user)
            {   
                $query2 = "select * from magazijn WHERE artikelnr = ".$user->artikelnr."";
                $row = mysql_fetch_array( $query );
            
                foreach ( self::find_by_sql($query2) as $magazijn)
                {
                echo "<table class= order_overzicht border= 0 width= 680>";
                echo "<tr>    
                        <td width= 100>".$magazijn->artikelnr."</td>            
                        <td width= 100>".$magazijn->productnaam."</td>
                        <td width= 40>".$magazijn->magazijn_plaats."</td>
                        <td width= 40>".$magazijn->aantal."</td>
                        <td width= 40>".$user->aantal."</td>
                      </tr>
                      </table>";
                }
            }
?>

The problem i have now is, that i want it to do the following.
for example someone orders 430 packages of Haribo Kers Cola (see imageshack upload). I first want it to empty spot 16 in the wherehouse.
Only when spot 16 is empty, i want it to go to the next spot (19) wich contains the same product.

the end result would be something like this:
