hello folks

 

its been along time since iv'e been on here, but iv'e just start playing with php again and i would like some help please.

 

// *-----------------------------------------------------------*
// * check_team_total()                                        *
// *                                                           *
// * Makes sure that no dreamteam has a value of more than     *
// * £50 million                                               *
// *-----------------------------------------------------------*


function check_team_total($player_1, $player_2, $player_3, $player_4, $player_5, $player_6, $player_7, $player_8, $player_9, $player_10, $player_11) {

include("passwords.inc");

$connection = mysql_connect($host, $user,$password) or die ("Couldn't connect to server.");
$db = mysql_select_db($database, $connection) or die ("Couldn't select database.");

$query  = "SELECT sum(price) 'total' ";
$query .= "FROM dreamteam ";
$query .= "WHERE dreamteam.id ";
$query .= "IN ('$player_1', '$player_2', '$player_3', '$player_4', '$player_5', '$player_6', '$player_7', '$player_8', '$player_9', '$player_10', '$player_11')";
  

$result = mysql_query($query) or die ("<font color='#ffff00' size='4'>Error! checking your team total!    (3)");

$total = mysql_fetch_assoc($result);

if ($total['total'] > 50) { // change to 40 for normal seasons 50 for the world cup
	global $truetotal;
	$truetotal = $total;		
	return False;
} else {
	return True;
}

}

 

i need to be able to use $truetotal as a global so i can pull it in a few places.ive added this but i cant get it to work,

global $truetotal; $truetotal = $total;

 

please could you get me started again

many thanks jason

Do you mean:

 

<?php
global $truetotal;

$total = $truetotal;

 

Otherwise, you're just giving $truetotal the value of $total, so there is no reason to even make $truetotal global.

By somewhere else do you mean in another function, another file, just somewhere different in the same file?

hello amtran

 

in the function it it used for adding up the total and checking if its not above 50

 

i would like to be able to use it within the same file just call back the total and use it out side that function

if you get what i mean.

You could have it return the value, instead of True or False.

 

So:

 

if ($total['total'] > 50) { // change to 40 for normal seasons 50 for the world cup

      global $truetotal;

      $truetotal = $total;     

      return $truetotal;

The global keyword and the $GLOBALS superglobal variable are both one of the very bad ideas implemented in PHP. Just saying.

 

Learn how to pass things by argument and how to return values from a function.
