Why can't I "post" these variables ?

HI All

I am having a very difficult time using checkboxes to post onto a seperate page. I have already searched the forum and have found a method to post the checkbox variables from a static form into a new page (which works fine), but every time I try to apply it to a script using a dynamically generated form it fails. For the life of me can't figure out why.

My form creation script is as follows:

echo "<form method=\"post\" action=\"test3.php\">
<table border=0 bgcolor=grey>";

	for ($i = 0; $i < $num_results; $i++)
	{
		$row = mysql_fetch_array($result);
		echo '<tr>
					<td><strong>'.($i + 1).'.</strong>&nbsp;&nbsp;&nbsp;&nbsp;'.stripslashes($row['username']).'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</td>
					<td><input type=text name=\"stuff[]\" value="'.stripslashes($row['username']).'">
				</tr>';
	}
	echo "	
			</table><br>
			<input type=\"submit\" value=\"  Delete User  \"><br>
			</form>
			<br>";

The above script works fine, but every time I "submit" it, the array does not seem to get posted to "test3.php". I get an error saying "Variable passed to each() is not an array or object". The code for "test3.php" is as follows:

<?
while($x = each($stuff))
echo "$x[0] => $x[1]<br>";

?>

Any ideas?

Straight up I would get rid of the [] in your input code

name=\"stuff[]\"

that is probably the problem

I don't think that the [] is the problem. As I have used it in other scripts and they work fine. If i don't use [] can I still build an array variable? I thought the [] was required to set the variable as an array.

A [] IS required to set a variable as an array but I have never come accross an HTML object with an Array as a name. If you can explain what you are trying to get to happen then i might be able to help more.

Ben is using form variable arrays as described in

http://www.php.net/manual/en/faq.html.php#faq.html.select-multiple

Well, an off-the-cuff test:

----zonk.php-----8<----
<?php
if($submit!='')
{ print_r($stuff);
}
?>
<body>
<form action="zonk.php">
<input type="text" name="stuff[]" value="O">

<input type="text" name="stuff[]">
<input type="text" name="stuff[]" value="ZZZ">
<input type="submit" name="submit" value="Submit">
</form></body>
------->8--------------

worked out fine for me, so let's have a closer look.

Either my eyesight's going or your code looks fine. Waitatick - are those backslashes before the double quotes supposed to be there? I thought for a moment that they'd been slipped in by the forum software. They'll cause grief if they're real.

If they are only a mirage, then I'll have to put the blame on your register_globals config setting.

Thanks so much. Problem finally soved. It was the fact that I had added backslashes to the variable name.

They were there because I thought you had to escape all " character within a PHP script. I guess I still don't quite understand under what circumstances I need to escape characters and under what circumstances I do not.

Thanks everybody for helping me out, very much appreciated.
