function not defined problem

[patrioticcow]

hello.
i get returned this error "user1 not defined".

the user1, user1, ... are an array
but somewhere is getting stuck

thanks a lot,

here is my code

if(!isset($_POST['list'])){
?>
<form action="listings.php" method="post">
    <input type="hidden" name="link" value="">
<?
echo '<select name="list[]" multiple="multiple">';
while ($row = mysql_fetch_assoc($result))
{
    echo '<option>' . $row['username'] . '</option>';
}
echo '</select>';
?>
<input type="submit" name="submit" id="submit" value="Submit" />
</form>
 <?php } else {
            $usernames = $_POST['list'];
            $link="http://www.exploretalent.com/model_page.php?talentnum=";
            $IDS = implode('-',$_POST['list']);?>
<script type="text/javascript" >
    var uids = new Array(<?php echo implode(',', $_POST['list']); ?>);
</script>
<a href="#" onclick="publishStream('<?php echo $link;?>',uids); return false;">Click to Publish on WALL.</a><?php }?>

here is the publishStream() that is called

function publishStream(link,IDS){
                var x;
                for (x in IDS) { //- pass in array of ids, loop through the ids here.
                streamPublish("Vote for me here", 'Visit Explore Talent', 'Checkout', link+IDS[x], "Facebook Application");
            }
            }

how doe's the JavaScript-array really look like? is it a valid JavaScript-array? is the array in any way extended by an additional lib (jQuery or whatever)? basically a JavaScript-Array must look like:

var arr = [1, 1, 2, 4, 'foo'];

java array

the array is set up in php. im ['list'].

i am posting it in the select list.
\then i implore this variable:

var uids = new Array(<?php echo implode(',', $_POST['list']); ?>);

witch is gonna return everything from the usernames field from my database.
then i send each result to that function

but i get that the results that come from UIDS (like: user1, user2, ...) are not defined

[gits]

i see that - but does:

<?php echo implode(',', $_POST['list']); ?>

writes a comma separated list of strings or numbers? note that when it writes the values and those values should be strings then you would need to add the quotes around every element - otherwise that values are treated as variables that are of course undefined ...

if i use

<?php echo implode('"', $_POST['list']); ?>

i get:

Error: missing ) after argument list
Source Code:
var uids = new Array(user1"use r2"user3");


and

Error: uids is not defined

[gits]

it has to look like this:

var uids = new Array("user1", "user2", "user3");

or better:

var uids = ["user1", "user2", "user3"];

[patrioticcow]

if i use

 <?php echo implode('","', $_POST['list']),'"'; ?>

i get

var uids = new Array(user1","user2","user3");\n

i cant get a " in the beginning of user1


by the way, thanks for taking some time to help me with this

[gits]

what about something like this?

<?php echo '"'.(implode('","', $_POST['list'])).'"'; ?>

[patrioticcow]

that worked :)

and now i click on this link:

<a href="#" onclick="publishStream('<?php echo $link;?>',uids); return false;">Click to Publish on WALL.</a><?php }?>

and if goes to this function:

function publishStream(link,IDS){
  var x;
  for (x in IDS) {
  streamPublish("Vote for me here", 'Visit Explore Talent', 'Checkout', link+IDS[x], "Facebook App");
  }}

the trick here is this IDS[x] to take one by one the whatever is returned from that array

the IDS are defined like this:

$IDS = implode('-',$_POST['list']);?>
