get length givin' me hard time

[bassouma86]

hey there

i was trying 2 use the count() to get the length of an array.

it should be sth like variable = count(ArrayName);

but i have a problem with my IIS server that makes me access the array (an HTML list of options using sth like

foreach ( $_GET["products"] as $value )

so the count() should be variable = count($_GET["products"]);

Is this right or I'm i on the wrong track here ???

cause anyway it ain't workin' :mad:

btw the purpose 4 gettin' the length of my array of options is to know when the array is empty so that i could handle that case cause i have a script that runs like a charm when i choose one option or more but when i choose none it makes an error :confused:

so if there's a way around I'd appriciate it ;)

thx in advance & good night

"length" is the word in order to get the length of an array in ActionScript, but I am not sure you are talking about it...

Yeah he is talking about PHP here.

So whats the problem count() doesn't work? If it is null, then php will not know its an array. How about if

if($_GET["products"] != null && sizeof($_GET["products"]) > 0 )

hey there

I integrated freddycodes' code into mine & came up with this :


if($_GET["products"] != null && sizeof($_GET["products"]) > 0 )
{
foreach ( $_GET["products"] as $value )
{
print "<li>".$value."<br>\n";
}
}
else
{
print "EMPTY";
}


The products array is an array of HTML multiple options list.

it works fine when i select an option or more but when i choose none of 'em it outputs an error Notice: Undefined index: products in e:\inetpub\wwwroot\poll\data.php on line 13
but still prints EMPTY :confused:

I'm still lost in here
plz advice :)
thx
