Re: [PHP] Array questions...
I won't address the main issue of your question, since it looks like that has
been solved. But I want to point out a few other things that might help you.
Follow along below...
Jason Pruim wrote:
So for some reason, arrays always mess me up... I don't know what it is,
but it just hasn't clicked yet... So I'm sure this is a simple question
for someone who knows and understands arrays :)
So with that being said here's the code I'm using:
$self = $_SERVER['PHP_SELF'];
$i="0";
if (isset($_GET['txtNum'])) {
$numBox= $_GET['txtNum'];
$_SESSION['num'] = $_GET['txtNum'];
}else{
here you need to make sure that $_SESSION['num'] exists.
If not you will get a E_NOTICE warning level error.
So, you should have this
} else if ( isset($_SESSION['num']) ) {
$numBox = $_SESSION['num'];
}
And then follow up the previous thing with this else statement
} else {
echo 'no "num" set';
// AND / OR
$numBox = 0;
}
echo "store box variable". $_SESSION['num'];
echo <<
How many boxes?
HTML;
$NumArray= Array($_POST['txtNumArray[]']);
echo <
Route #Pieces in
routeWeight of route
TABLE;
echo "";
Change this to "post" <-- spec says lower case on the value
And, you could get rid of the echo and move it to the last line of the previous
HEREDOC statement
while($i < $numBox){
echo <<
Here you would use just value="txtNumArray[{$i}]"
value="txtNumArray[$i]">
Here you would use just value="{$i}"
Here you would use just value="txtPiecesArray[{$i}]"
value="txtPiecesArray[$i]">
Here you would use just value="{$i}"
Here you would use just value="txtWeightArray[{$i}]"
value="txtWeightArray[$i]">
Here you would use just value="{$i}"
HTML;
$i++;
}
echo "";
The reason I would do the above, is to make sure that all three arrays are in
sync.
What I'm attempting to do, is grab the info out of txtNumArray[] and put
it into the variable $numArray Sounds easy enough right? Well I've tried
using $NumArray = Array($_POST['txtNumArray[]'); but that's not
working... I've tried $NumArray = $_POST['txtNumArray[]']; which didn't
work... and I've looked on the php manual, but they all assume you
understand this stuff which I do not :)
Anyone know what I'm doing wrong? Or could at least point me to some
text like "Array's for Dummies"? :)

I think you want the following after performing a very cursory look at
your sample.

Amazing what happens when you pull a few [] off for completness:

works as I wanted :) Anyone have any texts that could help me get a
better grasp on arrays though? :)
