Re: 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 <<<HTML

    <form method="GET">
    How many boxes? <input type="text" size="2" name="txtNum">
    <BR>
    <input type="submit"></form>

HTML;

    $NumArray= Array($_POST['txtNumArray[]']);

echo <<<TABLE

    <P>Weight of 100 pieces: <input type="text" size="5" name="txtPieceWeight"></P>
    <table border="1"><tr><th>Route #</th><th>Pieces in route</th><th>Weight of route</th></tr>
    TABLE;

echo "<form method=\"POST\" action=\"$self\">";

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 <<<HTML

        <tr>
        <td>
        <input type="text" size="5" name="txtNumArray[]" 

Here you would use just value="txtNumArray[{$i}]"

value="txtNumArray[$i]">

Here you would use just value="{$i}"

        </td>
        <td>
        <input type="text" size="5" name="txtPiecesArray[]" 

Here you would use just value="txtPiecesArray[{$i}]"

value="txtPiecesArray[$i]">

Here you would use just value="{$i}"

        </td>
        <td>
        <input type="text" size="5" name="txtWeightArray[]" 

Here you would use just value="txtWeightArray[{$i}]"

value="txtWeightArray[$i]">

Here you would use just value="{$i}"

        </td>
        </tr>

HTML;

        $i++;
        }   echo "<input type=\"submit\"></form>";

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"? :) -- Jason Pruim Raoset Inc.
