foreach help please

KashKurcura

Can someone please tell me why this foreach will not work? Is there something that I'm missing? Globals are off and all that shows up is...

result:

-

form:

foreach:

foreach ($_POST[Player] as $key=>$value) {
print $FName[$key]. "-" .$LName[key]. "<br>";
}

scoppc

$firstname=$_POST['FName'];
$lastname=$_POST['LName'];
foreach ($firstname as $key=>$value) { 
print $key . "-" . $value . "<br>";
}
foreach ($lastname as $key=>$value) { 
print $key . "-" . $value . "<br>";
}

you should get the key and then -, followed by the value

Um, it looks like it's working to me - $_POST['LName'][0] etc. are empty...

Do a print_r($_POST) to check what's there and how it's numbered.

One thing to note is that if a hidden field has an empty value, it won't be included in the form submission. That could cause your arrays to go out of sync. I suggest that to avoid this you explicitly number the fields:

etc.

Just the thought of possibly contradicting Weedpacket makes me a bit quesy but here goes.

Your original code will work fine assuming you have the input statements surrounded by form tags and a submit button. Notice however that

$LName[key] should be $LName[$key]

And if register globals is off then you need to pull out the name arrays before your while loop.
$FName = $POST['FName'];
$LName = $POST['LName'];
$Players = $_POST['Player'];
foreach ($Players as ...

Using just the [] in your input elements without filling in an index is fine.You will have trouble with check boxes since only the checked boxes will get posted back. Your hidden field's value should probably be the person's database id number so you know exactly what persone is being worked on.

Thanks ahundiak, Pulling out the arrays before they foreach did the trick, I did try that once but it was in the foreach itself. Thanks again!
