php
hi, i am a little new to php and although i have managed to pass values of session variables before this piece of code is leaving me puzzled
<form action="team_reg2.php" method="post" name="form1" class="cent" id="form1">
Team Registration
"; print "member$i"; print "\n"; print "\n"; print "Please enter only id
\n"; } ?> now this will pass via post to team_reg2.php
echo " please note your team id is 1
";
echo " your team members are :
";
for($i=1;$i<=$num;$i++)
{
$name='mem'.$i;
echo "$_POST[$name]
";
}
} else {
$str="select * from $query where (";
for($i=1;$i<=$num;$i++)
{
$name='mem'.$i;
$text="p_id='$_POST[$name]'";
if($i==1)
$str=$str.$text;
else
$str=$str.' or '.$text;
}
$str=$str.')';
$query2=$str;
echo "$str
";
// echo "$query2";
$que=mysql_query($query2,$con) or die(mysql_error());
$num=mysql_num_rows($que);
if($num!=0)
{
while($result=mysql_fetch_array($que))
{
echo "$result[p_id] is already registered in team $result[t_id]
";
}
//include("reg_team.html");
}
else if($num==0)
{
//echo $query;
$query2="select max(t_id) from $query";
$que=mysql_query($query2,$con) or die(mysql_error());
//echo "$que
";
$result=mysql_fetch_array($que);
$max=$result['max(t_id)'];
$max++;
$num=$_SESSION['max_team'];
for($i=1;$i<=$num;$i++)
{
$name='mem'.$i;
if($_POST[$name]!="")
{
$query2="insert into $query values($max,'$_POST[$name]')";
$que=mysql_query($query2,$con);
}
}
echo " please note your team id is $max
";
echo " your team members are :
";
for($i=1;$i<=$num;$i++)
{
$name='mem'.$i;
echo "$_POST[$name]
";
}
}
} ?>
i have done session_start(); at the beginning of the page itself. The problem is that echoing $_SESSION variables in second file is not printing anything.
someone please explain me whats going on. thank you
