if ($create) {
return true;
} else {
return false;
}
}
}
?>

here is my other script
<?php

//get all teams first and set them in available array
$get_all = mysql_query("SELECT * FROM teams");
$max_teams = mysql_num_rows($get_all);
$i = 1;
$rand_team = rand(1,$max_teams);
while($team = mysql_fetch_assoc($get_all)) {
$available[$i] =  $team['teamname'];
$i++;
}

// end getting all teams
for ($i = 1; $i < $Scheduler->max_teams; $i++) {
//get the two teams
$get_team1 = rand(1,$Scheduler->max_teams);
$get_team2 = rand(1,$Scheduler->max_teams);
$team1 = $available[$get_team1];
$team2 = $available[$get_team2];
if ($Scheduler->CheckTeams($team1,$team2)) {
if ($Scheduler->createMatch($team1,$team2)) {
echo 'Scheduled '.$team1.' to play '.$team2.' in week '.$Scheduler->week.'<br />';
}
}else {
$i--;
}


}

Hello,

I am fairly new at php (have been using HTML/CSS for a while but recently learned the php basics). I am building a website to allow clients to schedule through multiple massage therapists and I am struggling with the basic beginings of a scheduler scripts. If  someone can point me towards a tutorial or script that would be great, or answer any of the following questions:

1. What would be the best way to store each therapists weekly schedule (based on monday-sunday with start and end times) and propagate that info. to every day that a client might schedule on?
2. How do i get the day of the week based on the date?
3. How do i display a calendar that lets them choose the date?

Can someone help me out with making a bat file. I cant find a good set of directions on google.

I have window scheduler all working in running but it runs my script in note pad and not IE like I need it too.

I also read something about php cgi file for doing this same thing but cant make heads of tails out of it from reading about it in the manual.

Trying to run this http://localhost/gate/users/update.php
