[fairly basic php question, regarding a simple log-in system]

is because of how you register your sessions you need to remove the quotes from:

 

session_register("myusername");
//with 
session_register($myusername);

but as i said earlier that method is depreciated and you should use:

$_SESSION['username'] = $myusername;
//and to check of they are logged in
if(isset($_SESSION['username']){}

[fairly basic php question, regarding a simple log-in system]

replace:

session_register("myusername");

 

with:

 

$_SESSION['username'] = $myusername;

 

you could then fix the messy url problem by loading the username stright from $_SESSION['username'] or by using url rewriting( via htaccess not php)

[fairly basic php question, regarding a simple log-in system]

you could use a get variable and redirect like:

header("Location: /gallery/?user=".$myusername);

 

or you could have the index.php script in the gallery directory load the information based on the session that is set in the previous script

 

also you should be registering your sessions like this:

 

$_Session['username'] = $myusername;

 

as session_register is deprecated

 

[Date display help!]

yeah that one doesn't work either guess i cant think today

[Date display help!]

heres a fix of mine

<?php
    $date = -1*(mktime(0, 0, 0, 9, 19, 2009)-time());
    $diff = date('m,d,Y,h,i,s',$date);
    $unit = array('month','day','year','hour','minute','second');
    $diff = explode(',',$diff);
    $output = '';
    foreach($diff as $key => $time){
        if($time < 1){
            continue;
        }else if($time == 1){
            if($output != ''){
                $output .= ', '.$time.' '.$unit[$key];
            }else{
                $output .= ' '.$time.' '.$unit[$key];
            }
        }else{
            if($output != ''){
                $output .= ', '.$time.' '.$unit[$key].'s';
            }else{
                $output .= ' '.$time.' '.$unit[$key].'s';
            }
        }
    }
    $output .= ' ago';
    echo $output;
?>

try:

    $diff = explode(',',$diff);
    $output = '';
    foreach($diff as $key => $time){
        if($time < 1){

i was think about charging 10 hour but then how should i charge for the stuff after the initial work

[How much to charge]

i have a client who wants a web site that would

  -include 2 public pages

  -a admin only section for mass email and web site updating

 

i would also be in charge of finding a host(could use recommendations), purchasing the domains and maintaining the site

 

i think that i could easy build this site but what is a fair amount to charge for this, they want an offer and are going to compare it to two other offers so it needs to be competitive and as this would be my first client i have no idea what is fair
