session variable values are not being passed between pages - php

Question

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">
<p><strong>Team Registration</strong></p>
<?php
$con=mysql_connect("localhost","root","");
mysql_select_db("databolism",$con);
$result=mysql_query("select * from events where id=$_POST[event]",$con);
$row=mysql_fetch_assoc($result);
$num=$row['max_team'];
$_SESSION['max_team']=$num;
$_SESSION['event_id']=$_POST['event'];
for($i=1;$i<=$num;$i++)
{
print "<p><span id=\"sprytextfield$i\"\n>";
print "<label>member$i";
print "<input type=\"text\" name=\"mem$i\" id=\"mem$i\" />\n";
print "</label>\n";
print "<span class=\"textfieldInvalidFormatMsg\">Please enter only id</span></span></p>\n";
}
?>
now this will pass via post to team_reg2.php
<?php
$con=mysql_connect("localhost","root","");
if(!$con)
die("could not connect to db");
$db=mysql_select_db("databolism",$con);
$num=6;
$event=14;
$result=mysql_query("select * from events where id=$event",$con) or die(mysql_error());
$row=mysql_fetch_assoc($result);
$query='fantasia1_'.$row['name'];
$query2="select max(t_id) from $query";
$que=mysql_query($query2,$con);
$result=mysql_fetch_array($que) or die(mysql_error());
$chk3=$result['max(t_id)'];
if($chk3==NULL)
{
for($i=1;$i<=$num;$i++)
{
$name='mem'.$i;
if($_POST["$name"]!="")
{
$query2="insert into $query values(1,'$_POST[$name]')";
$que=mysql_query($query2,$con);
}
}
echo " please note your team id is 1 <br>";
echo " your team members are : <br>";
for($i=1;$i<=$num;$i++)
{
$name='mem'.$i;
echo "$_POST[$name]<br>";
}
}
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 "$str<br>";
// echo "$query2</br>";
$que=mysql_query($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 $result[t_id]<br>";
}
//include("reg_team.html");
}
else if($num==0)
{
//echo $query;
$query2="select max(t_id) from $query";
$que=mysql_query($query2,$con) or die(mysql_error());
//echo "$que<br>";
$result=mysql_fetch_array($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 $max <br>";
echo " your team members are : <br>";
for($i=1;$i<=$num;$i++)
{
$name='mem'.$i;
echo "$_POST[$name]<br>";
}
}
}
?>
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

Answer 1

You need session_start() in the second file, too.
