Outputting Javascript array values

[Rudy]

Hey guys,
There's a little PHP here, but I think this is a javascript issue... I am creating a javascript array, and within a php while() loop, I am adding values to the array and then am trying to output the results. However, what I want outputted to the browser is not being sent.

I am trying to output an image, but it is not happening.

Any ideas why this is happening?

*/

// Set the Directory Location
$directory = opendir('../premier_images/');

// Put every picture in the directory into an array
echo "<script type=\"text/javascript\">
		var output = new Array()
		var i = 0;
	";
while ($picture = readdir($directory)) {
	echo "	output[i] = " . $picture . "
		document.write('
			<div id='+output[i]+' style=\'<!-- display:none;-->align=center;valign=center;\'>
				<img src=\'../premier_images/'+output[i]+\'>
				<br />
			</div>
			');
		i++;
		document.write(i);
		";
}
// ignore this next line... it has a php function that I still need to switch over to a javascript function.... it's not causing any problems
echo "</script><br /><br /><input type='button' value='Next Photo' onClick=\"next_photo_gallery('".current($output)."', '".next($output)."')\">";
?>

erm... I think the problem is that your while loop is in php, but you are increasing var i in javascript lol.

Lets see what I can do:

<?PHP

		in a directory to select one picture. It will place all of the contents

*/

// Set the Directory Location
$directory = opendir('../premier_images/');

// Put every picture in the directory into an array
echo "<script type=\"text/javascript\">
		var output = new Array()
	";
$i = 0;
while ($picture = readdir($directory)) {
	echo "	output[".$i."] = " . $picture . "
		document.write('
			<div id='+output[".$i."]+' style=\'<!-- display:none;-->align=center;valign=center;\'>
				<img src=\'../premier_images/'+output[".$i."]+\'>
				<br />
			</div>
			');
		document.write(".$i.");
		";
$i++;
}
// ignore this next line... it has a php function that I still need to switch over to a javascript function.... it's not causing any problems
echo "</script><br /><br /><input type='button' value='Next Photo' onClick=\"next_photo_gallery('".current($output)."', '".next($output)."')\">";
?>

try that... I just did the "$i" bit in php instead of javascript...

It all seems a bit ott to be honest though... wouldn't it be much easier to do the whole thing in PHP?
