Function redirect to different page

[SFDonovan]

Let me explain.

If my page move.php has a function called like

checkmove($tid, $team_id);

Which checks to see if enemy exist on territory.

common.php has this function that ends like this.

//Look for enemy teams that may be on territory
$sql = "SELECT * FROM " . $prefix . "_tc_teams WHERE tid ='$tid' AND div_id != '$div_id'";
$result = $db->sql_query($sql); 
$enemy = FALSE;
	if ($db->sql_numrows($result) > 0) {
$enemy = TRUE; //Enemy exist on territory

If enemy = TRUE, I don't want to return $enemy to the move.php page but to redirect to attack.php page then what would be the best way to do this.

My usual redirect written like

Header("Location: modules.php?name=whatever&file=attack");

...wont send the arguments, $tid, $team_id.

This is purely a guess since I don't see most of your code. Maybe something like this will work.

<?php
...
$checkForEnemy = checkmove($tid,$team_id);
// if there is an enemy - ATTACK
if($checkForEnemy)
{ header("Location: modules.php?name=whatever&file=attack"); exit; }
// else continue
...
?>

<?php
function checkmove($tid,$team_id)
{
   global $sql,$prefix;
   //Look for enemy teams that may be on territory
   $sql = "SELECT * FROM " . $prefix . "_tc_teams WHERE tid ='$tid' AND div_id != '$team_id'";
   $result = $db->sql_query($sql); 
   if ($db->sql_numrows($result) > 0) 
      return TRUE;
   return FALSE;
} // function checkmove()

But to my understanding $checkForEnemy would only contain a true or false. It would not have the arguments $tid or $team_id.

See the thing is if I find enemy team_ids with the checkmove function I want to send the user to the attack.php page but I want to pass the $tid and $team_id.

Iv'e only used the Header( "Location: blah blah) to redirect.

Here is my funtion checkmove

//Check if enemy exist on territory if so attack
function checkmove($tid, $team_id){
require_once("mainfile.php");
$module_name = basename(dirname(__FILE__));
include_once("modules/$module_name/language/lang-english.php");
global $db, $prefix, $module_name, $admin_file;
define('INDEX_FILE', true);
$index = 1;

 //Find the value of the division ID. 
  $sql = "SELECT div_id FROM " . $prefix . "_tc_teams WHERE team_id ='$team_id'"; 
  $result = $db->sql_query($sql); 
  $mydiv = $db->sql_fetchrow($result);
  $div_id = $mydiv['div_id']; 

//Look for enemy teams that may be on territory
$sql = "SELECT * FROM " . $prefix . "_tc_teams WHERE tid ='$tid' AND div_id != '$div_id'";
$result = $db->sql_query($sql); 
$enemy = FALSE;
	if ($db->sql_numrows($result) > 0) {
$enemy = TRUE; //Enemy exist on territory

*and this is where I am trying to figure out how to return.

I think I might be missing what it is that you are trying to "return" at the end of this function. To me, it sounds like you want to search for "enemies" and either 1) continue the script if no enemies are found or 2) redirect to an "attack" page if there is an enemy.

The solution I see here is to end your function:

$result = $db->sql_query($sql);
if ($db->sql_numrows($result) > 0)
   return TRUE; // this will drop out of the function

header("Location: modules.php?name=whatever&file=attack&id=$tid&team=$team_id"); 
exit;
} // function checkmove()

Or am I missing something?

I am assuming that in your common.php file, your code continues after the checkmove() to figure out where the User wants to go. So your problem must be with your redirect - and you're not passing the proper info to your attack.php.

Since you're calling a new page, you'll have to pass any variable you need to that page via GET, SESSION, COOKIES, or save it to your DB.
