problem storing an array as a session variable

organik

I have a page which is a navigation and displaying sytem for picture galleries. I try to store some arrays in session variable...works perfectly fine with integers bur I have tried many ways for string and none worked...(I use a mysql class to retrive date from the database but it has no influence on my session problem)

here is the code :

<? require_once($_SERVER['DOCUMENT_ROOT']."/_inc/db.Class.php"); ?> 
<? require_once($_SERVER['DOCUMENT_ROOT']."/_inc/config.inc.php"); ?> 
<? 
if (!isset($level)) 
{ 
$level=0; 
} 
$new_level=$level+1; 
if (!isset($parent)) 
{ 
$parent=0; 
} 
if ($level!=0) 
{ 
session_start(); 
$till=$level+1; 
$db->sql = "SELECT nom FROM img_cat where id=".$parent; 
$q_res_top = $db->fetch_array($db->sql); 
if($q_res_top) 
{ 
$titre=$q_res_top['nom']; 
if ($level>1) 
{ 
for ($i=1;$i<$level;$i++) 
{ 
$array_id[$i]=$_SESSION["id"][$i]; 
$array_niv[$i]=$_SESSION["niv"][$i]; 
//I tried this solution with $_SESSION ["titre"] but it didn't work 
} 
} 
$array_id[$level]=$parent; 
$_SESSION["id"]=$array_id; 
$array_niv[$level]=$level; 
$_SESSION["niv"]=$array_niv; 
$array_titre=array("galerie"); 
if (isset($_SESSION["titre"])) 
{ 
array_push($array_titre,$_SESSION["titre"]); 
} 
$array_titre[$level]=$titre; 
$_SESSION["titre"]=$array_titre; 
} 
} 
?> 
<html> 
<head> 
<title>DYNAM GALERIES</title> 
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> 
</head> 
<body leftmargin="0" topmargin="0" marginwidth="0" marginheight="0"> 
<? 
if ($level!=0) 
{ 
?> 
<a href="<? echo $PHP_SELF?>";">galerie</a> | <? for ($i=1;$i<$till;$i++){echo "<a href='".$PHP_SELF."?level=".$_SESSION["niv"][$i]."&parent=".$_SESSION["id"][$i]."'>".$_SESSION["titre"][$i]."</a> | ";}?> 
<? 
} 
?> 
<table width="100%" cellpadding="5"> 
<? 
$db->sql = "SELECT * FROM img_cat where id_parent=$parent AND (child='y' OR galerie='y')"; 
$q_res = $db->query($db->sql); 
if($q_res) 
{ 
for($i = 0; $i < sizeof($q_res); $i+=2) 
{ 
?> 
<tr> 
<? 
$end=$i+2; 
for($j=$i;$j<$end;$j++) 
{ 
?> 
<td><? if ($end>sizeof($q_res) AND $j==$end-1){echo " ";}else { echo "<a href=\"".$PHP_SELF."?level=$new_level&parent=".$q_res[$j]['id']."\">".$q_res[$j]['nom']."</a>";}?></td> 
<? 
} 
?> 
</tr> 
<? 
} 
} 
else 
{ 
echo "<tr><td cospan='2'>la base est vide</td></tr>"; 
} 
?> 
</table> 
</body> 
</html> 

here is an exemple of the code that is generated : 
<html> 
<head> 
<title>DYNAM GALERIES</title> 
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> 
</head> 
<body leftmargin="0" topmargin="0" marginwidth="0" marginheight="0"> 
<a href="/galerie.php";">galerie</a> | <a href='/galerie.php?level=1&parent=45'>test</a> | <a href='/galerie.php?level=2&parent=46'></a> | <a href='/galerie.php?level=3&parent=48'>test</a> | <table width="100%" cellpadding="5"> 
<tr><td cospan='2'>la base est vide</td></tr></table> 
</body> 
</html> 

?>

as you can the see the array with integers are stored perfectly in session variables but it doesn't work with strings

Can somebody help???I am desperate...

[man]serialize()[/man]

thanks for your answer but could you be more specific...I don't know how to use this function

laserlight

Read the manual... by clicking on the link.

mrhappiness

$_SESSION['array in session'] = serialize($array);
$array = unserialize($_SESSION['array in session']);

organik

thanks everyone, I'll try this tonight

I tried the solution with the function serialize() but it didn't work...

I found another way to do : by storing each string in a different session variable and using a variable for the session variable name like this :

$_SESSION["titre".$level]=$titre;

but I still would like to find a way to store an array in a session variable and add a new field each time the page loads. So, if anyone has an example code for this purpose, could you post it please????

I know my english is not good. To explain my problem in a simplier way, I need something that works almost like a shopping cart, something that implements the url variables (variables can be strings) to an array...

bubblenut

Coul you post the code for how you used serialize(), because it should work 😕

Here is the code I tried :

<?  

if (!isset($level))  

  {  

  $level=0;  

  }  

$new_level=$level+1;  

if (!isset($parent))  

  {  

  $parent=0;  

  }  

if ($level!=0)  

  {  

  session_start();  

  $till=$level+1;  

  $db->sql = "SELECT nom FROM img_cat where id=".$parent;  

  $q_res_top = $db->fetch_array($db->sql);  

  if($q_res_top)  

    {  

    $titre=$q_res_top['nom'];  

    if ($level>1)  

      {  

      for ($i=1;$i<$level;$i++)  

        {  

        $array_id[$i]=$_SESSION["id"][$i];  

        $array_niv[$i]=$_SESSION["niv"][$i];  

//I tried this solution with $_SESSION ["titre"] but it didn't work 
        }  

      }  

    $array_id[$level]=$parent;  

    $_SESSION["id"]=$array_id;  

    $array_niv[$level]=$level;  

    $_SESSION["niv"]=$array_niv;  

    $array_titre=array("galerie");  

      if (isset($_SESSION["titre"]))
      {
      $array_titre=unserialize($_SESSION["titre"]);
      }
    else
      {
      $array_titre=array("galerie");
      }
    $array_titre[$level]=$titre;
    $_SESSION["titre"]=serialize($array_titre);
    }  

  }  

?>

I also tried this

$array_titre=array(unserialize($_SESSION["titre"]));
