session, post, get not working

[anotherphpnoob]

As the title says session, post and get are not working. This is what i use to initialize them. For get just switch session with get.

 

foreach ($row as $val)
          {  
            $_SESSION[$rowcount] = $val;
//              echo "<td>$val</td>\n";
                $rowcount=$rowcount+1;
      }

 

when i was using session i would check to make sure that they were working with a couple of these lines in the same php document.

 

echo "Session row 1 = ".$_SESSION[0]."<br />";
echo "Session row 2 = ".$_SESSION[1]."<br />";

 

then on the next page where I was trying to receive the variables i was using this just to start off with and make sure i was getting the variables.

 

	session_start();
if(!isset($_SESSION[1])){
echo "help1";}else{$var=$_SESSION[1];
}
echo $_SESSION[1];
echo $var;

 

if i switch to post and get i get the same results. if there is an easier way to pass variables between pages id love to hear them

What exactly are you trying to accomplish?

[anotherphpnoob]

I'm taking information from a database and i want to bring it to a new page where i can access it. The database connection, settings and what not are fine.

I think you're going to need to post more code. Can you post the 2 scripts that you posted parts of above?

[anotherphpnoob]

script.php

 

<?php 
session_start();
//database server 
define('db_server', 'localhost'); 

//user, password, and database variables 
$db_user = 'user'; 
$db_password = 'password';     
$db_dbname = 'people'; 


/** 
* Run MySQL query and output  
* results in a HTML Table 
*/ 
function outputQueryResults() { 

   $username=$_POST['name'];
   $password=$_POST['pass'];
   $count=0;
   $rowcount=0;

  //run a select query 
  $select_query = "SELECT * FROM names WHERE username= '".$username."' AND password = '".$password."'"; 
  $result = mysql_query($select_query); 
  //output data in a table 

  while ($row = mysql_fetch_row($result))
  {

  
 // echo "<table>\n";
  //echo "<tr>\n"; 
      foreach ($row as $val)
  {  
    $_SESSION[$rowcount] = $val;
	//echo "<td>$val</td>\n";
	$rowcount=$rowcount+1; 
	$count=$count+1;
      } 
      //echo "</tr>\n";
  
  } 
  if(is_null($row)||empty($row)&& $count==0)
  {
	if (!empty($_SERVER['HTTPS']) && ('on' == $_SERVER['HTTPS'])) 
	{
		$uri = 'https://';
	} 
	else 
	{
		$uri = 'http://';
	}
	$uri .= $_SERVER['HTTP_HOST'];
	header('Location: '.$uri.'/error.html');
  }else{

  //echo '</table>';
//echo "Session row 1 = ".$_SESSION[0]."<br />";
//echo "Session row 2 = ".$_SESSION[1]."<br />";
//echo "Session row 3 = ".$_SESSION[2]."<br />";
//echo "Session row 4 = ".$_SESSION[3];
if (!empty($_SERVER['HTTPS']) && ('on' == $_SERVER['HTTPS'])) 
{
	$uri = 'https://';
} 
else 
{
	$uri = 'http://';
}
$uri .= $_SERVER['HTTP_HOST'];
header('Location: '.$uri.'/index.php');
  }
} 

//connect to the database server 
$db = mysql_connect(db_server, $db_user, $db_password); 
if (!$db) { 
   die('Could Not Connect: ' . mysql_error()); 
} else { 
  echo "Connected Successfully...\n"; 
} 
//select database name 
mysql_select_db($db_dbname); 

//run query and output results 
outputQueryResults(); 

//close database connection 
mysql_close($db) 
?> 

 

index.php

 

<?php

session_start();
if(!isset($_SESSION[1])){
echo "help1";}else{$var=$_SESSION[1];
}
echo $_SESSION[1];
echo $var;


?>

I'm not so sure the query is actually succeeding. Let's find out, though.

 

$result = mysql_query($select_query) or die(mysql_error());

[anotherphpnoob]

the SQL query is fine. i built the page to show me that it was working. I then commented out all the stuff because i didnt want it to show up and built the rest of the stuff so that when it does work it, $_SESSION gets its variables and then goes to index.php.

this code is one </table> short but if you look in the code i posted before its there.

 

 // echo "<table>\n";
  //echo "<tr>\n"; 
      foreach ($row as $val)
  {  
    $_SESSION[$rowcount] = $val;
	//echo "<td>$val</td>\n";
	$rowcount=$rowcount+1; 
	$count=$count+1;
      } 
      //echo "</tr>\n";
  
  }

 

I also tested whether or not $_SESSION was even getting anything from that statement later on in the page, and then proceeded to comment that out as well.

 

  //echo '</table>';
//echo "Session row 1 = ".$_SESSION[0]."<br />";
//echo "Session row 2 = ".$_SESSION[1]."<br />";
//echo "Session row 3 = ".$_SESSION[2]."<br />";
//echo "Session row 4 = ".$_SESSION[3];

Are you doing this on a system with error_reporting set to E_ALL and display_errors set to ON so that all the php errors would be reported and displayed, such as header errors that would prevent session variables from working?

[anotherphpnoob]

error_reporting was set to E_ALL however display_errors was not set to ON.

both of these are now set to the following.

display_errors = ON

error_reporting = E_ALL

 

ran through the scripts as usual, not sure what im looking for, or what should or should not be happening.

Does a phpinfo() statement show that those two settings actually have those values, in case the php.ini that you are changing is not the one that php is using?
