Hello,

I am trying to get values from a session into a array, this let me set my posted values back to my select-form. The user can set up a ranking from illustrations.
What goes wrong?
When i set up a echo i will get back: 3 4 0 0 0 0 0 0 0 0 0 0 0 0 0 0

Top of page:

<?
session_start();

include('connect.php');

$link = dbconnect();
$arr = "". $_SESSION["illustrations"];
$array = explode(";",$arr);

for($i=0; $i < count($array); $i++)
{
$iv = explode(":",$array[$i]);

$idvalue[$iv[0]] = $iv[1];

echo $iv[1];

}
?>

body:

echo "<tr><td><img src=\"../stijlen/".$row["filename"]."\"><td>"."</td></tr></table></td><table></tr>\n";
echo "<tr><td><select name=\"I".$row["illustrations_id"]."\" size=\"1\">";

    if( in_array("I".$row["illustrations_id"], $iv ) ) echo " selected";

    if( in_array("I".$row["illustrations_id"], $idvalue ) ) echo " selected";

    for($i=0; $i<6; $i++)
    {
        if( in_array("I".$row["illustrations_id"], $iv ) ) echo " checked";

        echo "<option value='$i' $i>$i</option>";
    }
    echo "</select></td></tr>\n";

Please help!

    Echo $illustrations out as well. Looking at the code it must be what's actusally in there that is causing the problem.

      $illustrations is not the problem. The problem is in the array, i just started with arrays...

      Somebody can help?

        I believe you may be trying to set up multi-dimensional arrays in your for loop. Here is a simplified model that I think may help:

        <?php
// $arr = id number: rating relationships
$arr = '1:2; 2:4; 3:5; 4:5; 5:8; 6:6; 7:0; 8:0; 9:2; 10:6';

// explode into pairs of id:value
$array = explode(';',$arr);

for($i=0; $i < count($array); $i++){
    // explode again into distinct id to value
    $iv[$i] = explode(':', trim($array[$i]));
    $idnumber[$i] = $iv[$i][0]; // number
    $idvalue[$i] = $iv[$i][1]; // rating value
    // print results
    echo 'ID: ' . $idnumber[$i] . ', Rating: ' . $idvalue[$i] . '<br />' . "\n";

}
?>

        I hope that I understand you correctly and that this helps a little. (I know it is way simplified...)

          I get the following printed values

          ID: I123, Rating: 4
          ID: I124, Rating: 3
          ID: I125, Rating: 5
          ID: I126, Rating: 1
          ID: I127, Rating: 0
          ID: I128, Rating: 5
          ID: I129, Rating: 0
          ID: I130, Rating: 0
          ID: I131, Rating: 0
          ID: I132, Rating: 0
          ID: I133, Rating: 0
          ID: I134, Rating: 0
          ID: I135, Rating: 0
          ID: I136, Rating: 0
          ID: I137, Rating: 0
          ID: I142, Rating: 0

          I can't get them in my selectboxes. That's my whole problem.

          My complete code is:

          <?
          session_start();

          include('connect.php');

          $link = dbconnect();
          $arr = "". $_SESSION["illustrations"];
          $array = explode(";",$arr);
          $iv = explode(":",$array[$i]);

          for($i=0; $i < count($array); $i++)
          {
          $iv = explode(":",$array[$i]);
          $idnumber[$i] = $iv[$i][0];
          echo $iv[1];
          }

          for($i=0; $i < count($array); $i++){
          $iv[$i] = explode(':', trim($array[$i]));
          $idnumber[$i] = $iv[$i][0];
          $idvalue[$i] = $iv[$i][1];

          echo 'ID: ' . $idnumber[$i] . ', Rating: ' . $idvalue[$i] . '<br />' . "\n";

          }

          ?>
