PHP sending data to next page by $_GET

except for 1st, values for other variables not transferred to new page

[zollerwagner]

After processing some form input, I want to send the user to a new page like this:

header("location: /page.html?mode=del&cat=$cat&ann=$ann");

When I do that, the new page appears and the new page receives the value for the first variable. For some reason the second and third parts of the data aren't received in the new page, although they are present right before this line in the sending page.

What am I doing wrong?

You can check what's arriving at the new page.

foreach ($_GET as $key=>$val) echo "<br>$key $val";

Also, have you tried just using the ampersand? It could be that &amp; isn't being handled as you might expect.
header("location: /page.html?mode=del&cat=$cat&ann=$ann");

I think, that you have to use ampersant, not the html symbol of it:

header("Location: /page.html?mode=del&cat=$cat&ann=$ann");

What's in the $cat and $ann? Remember, that they cannot have any & or spaces!

Thanks for the responses.

Interestingly, it does work if I use & and not &amp; .

Perhaps I've taken the use of &amp; too far. Given that this isn't a link and doesn't appear in the HTML at all, maybe there is no need to use the &amp;?

You're correct. There's no need for the &amp; here. This never shows up in an HTML document, so it will never face a validator, so raw ampersands are the correct way to go.

However, you should be encoding your url variables. There are certain characters that can't be send through a URL "raw". Look into the the urlencode [us3.php.net] function.

header("location: /page.html?mode=del&cat=".urlencode($cat)."&ann=".urlencode($ann));
