Netscape and empty array values

[Anon]

Hi,

I'm working on a program that sends an array built from form elements. If some of the elements aren't selected then I need to throw out the empty values in the array.

So I first only allow unique values in the array

//remove blank values
$loci=array_unique($loci);

then I arrange them

//arrange
sort($loci);

And then remove any empty ones if they exist

//remove first element if blank
if($loci[0]=='')array_shift($loci);

This works fine in IE but in Netscape it refuses to get rid of the empty value, bring me to the conlusion that it has something weird in it passed by the NS browser. Anybody know what it could be?

Thanks

Are you passing variables in the URL?

like this

/script.php3?item=234&other=something

I had a similar problem once and it was related to the way I passed the variables in the URL... make sure there are no spaces.

You might try using "&" for the ampersand instead of plain old "&"...that's actually the valid way to do an "&" in HTML.

Yeah,
Thanks Mark.

Netscape seemd to be passing a space, the form value seemed to default to that. I had to 'select' it in the HTML as nothing. I don't really understand what happened but it works now.
