multiple select drop down menu not retrieving correct data

phpnewbie26

I currently have two drop down menus where the second one is populated from the first one. My second drop down menu should be able to do multiple selection. I have searched online and found out how to do so (add in multiple and put brackets after name), but unfortunately when I retrieve the data on the next page, it seems that none of the selections were added to the variable array. On the other hand, it "POST"-ed the null value which is 1. My coding looks pretty much the same as everyone else's so I don't know why it doesn't work. Hopefully someone can shed some light. Thanks in advance. Here's my current coding.=)

Theres a lot of code before this but this is the form part.

// Get the posted data, if any, or initialize as null or today's date

   ($type = @$_POST['Type']) or $type = 1;

   ($item = @$_POST['Item']) or $item = 1;

   ($name = @$_POST['name']) or $name = null;

   ($firstdate = @$_POST['firstdate']) or $firstdate=date("ymd");

   ($lastdate = @$_POST['lastdate']) or $lastdate = date("ymd");
 
   // Open the form element

echo '<form action="" method="post"> ';  

echo '<p>User(Type username or all): <input type="text" name="name" value="', htmlentities($name),'"/><br//></p>';

echo '<p>Start of Period (yymmdd): <input type="text" name="firstdate" value="', htmlentities($firstdate),'"/><br//></p>';

echo '<p>End of Period(yymmdd): <input type="text" name="lastdate" value="', htmlentities($lastdate),'"/><br//></p>';
 
 // Print first select

   echo '<select name="Type" onchange="submit();">';

   echo '<option value="">- All projects -</option>';
 
   foreach(array_keys($items) as $_type) {

       // Check if this type was selected last submit

       $selected = ($type == $_type ? 'selected="selected"' : '');
 
       // Print this type as an option

       echo '<option value="'. $_type .'" '. $selected .'>'. $_type .'</option>';

   }

   echo '</select>';
 
   // Print the second select

   echo '<select multiple name="Item[]">';

   echo '<option value="">- All phases -</option>';

   if($type) {

       foreach($items[$type] as $_item) {

           // Check if this item was selected last submit

           $selected = ($item == $_item ? 'selected="selected"' : '');
 
           // Print this item as an option

           echo '<option value="'. $_item .'" '. $selected .'>'. $_item .'</option>';

       }
 
   }

   echo '</select>';

echo "<br><br>";
 
   // Close the form element

   echo '</form>';
 
    //Do something with the selected items

 $_SESSION['name'] = $name;

 $_SESSION['type'] = $type;

 $_SESSION['item'] = $item;

And on the next page, I do this to check what was in $item. (Again, this is just a snippet of my code)

<?php

//opens session

session_start();

$items=$_SESSION['items'];

print_r($item);

?>

Thanks again.

You're confusing the **** out of yourself with this plural and singular item/items.

At the top you call it $item, in the foreach() you call $items.

avoid doing this by calling the plural (array) version something like $all_Items.

despite the confusion between singular and plural, unfortuantely, that is not the problem. Items is the array of all my information that I collected before this form. My form works when I take out the "multiple" out of the form. So I know that the singular and plural item isnt'the problem.
