Multiple text boxes with same name [solved]

Recommended Posts

Hi all,

My apologies if this question has already been asked before.  I've tried searching the forums and googling but no success, as the code given on multiple sites does not work (on my server, anyways).

Basically I have a form with multiple textboxes with the same name, and I'm using the square brackets as suggested by php.net:

[code]<input type="text" name="txtQty[]">[/code]

There's a few of these lines in the HTML.  Now in the PHP page that the form is submitted to, I do a die(print_r($_POST)) ;  and get:

[code]
Array
(
    [cboCompanyName] =>
    [txtInvoiceDate] => 2006-07-30
    [txtInvoiceId] => 1
    [txtPONumber] =>
    [cboTerms] =>
    [cboItem] => Array
    [txtQty] => Array
    [txtDescription] => Array
    [txtRate] => Array
    [cboTaxCode] => Array
    [txtInvoiceMemo] =>
)
1
[/code]

Looks like everything is great, so I do:

[code]
$txtQty = $_POST['txtQty'] ;
die($txtQty[0]) ;
[/code]

And what is printed is not the value of the first textbox, but the letter 'A' (the first character in the string "Array").  Why is PHP not returning an array of values as expected but rather the string "Array"?

Thanks for any help.

Brian

you see array because that is what you have, an array.

if you want to see the elements of the array you could do something like this

foreach($_POST['txtQty'] as $qty) {
echo $qty.'<BR>';
}

now instead of seeing "array" you will see each of the elements in that array

hope this helps

I tried using array_keys before thinking that was the issue.  When I tried your code or my array_keys($_POST['txtQty']) code, I get the following error:

[code]Warning: Invalid argument supplied for foreach() in processInvoice.php on line 43[/code]

Which looks like that element really is just the string "Array", which doesn't really make any sense...

Sure, it's fairly long though (the lines of the invoice form are repeated a few times).  I was just thinking it had something to do with the checkInvoiceForm() javascript (which currently does nothing but call window.document.frmInvoice.submit()) but I tried bypassing that with no change.

My apologies, there was a chunk of code in a common PHP file that tried to deal with magic quotes:

[code]if (!get_magic_quotes_gpc()) {
if (isset($_POST)) {
foreach ($_POST as $key => $value) {
$_POST[$key] = trim(addslashes($value));
}
}

if (isset($_GET)) {
foreach ($_GET as $key => $value) {
$_GET[$key] = trim(addslashes($value));
}
}
}[/code]

I'll need to look for a better way of dealing with ' and slash characters in form submissions, since this one can't deal with $_POST arrays, unless someone knows of one off hand?

Thanks again,
Brian

In case anyone needs it, I modified the code slightly to deal with arrays in $_POST up to one level deep:

[code]
if (!get_magic_quotes_gpc()) {
if (isset($_POST)) {
foreach ($_POST as $key => $value) {
if (is_array($_POST[$key])) {
foreach ($_POST[$key] as $keysub => $valuesub) {
$_POST[$key][$keysub] = trim(addslashes($valuesub)) ;
}
} else {
$_POST[$key] = trim(addslashes($value));
}
}
}

if (isset($_GET)) {
foreach ($_GET as $key => $value) {
if (is_array($_GET[$key])) {
foreach ($_GET[$key] as $keysub => $valuesub) {
$_GET[$key][$keysub] = trim(addslashes($valuesub));
}
} else {
$_GET[$key] = trim(addslashes($value));
}
}
}
}
[/code]

well, I just tried a little test with your html and it seems to be working here is the result I got

Array

            [1] =>
            [2] =>
            [3] =>
            [4] =>
            [5] =>
            [6] =>
            [7] =>
            [8] =>
        )

    [cboTaxCode] => Array
        (
            [0] => .
            [1] => .
            [2] => .
            [3] => .
            [4] => .
            [5] => .
            [6] => .
            [7] => .
            [8] => .
        )

    [txtInvoiceMemo] =>
    [test] => test
)

note the values in txtQty

I actually got it working, since the magic quotes code that was in the template was messing up the arrays in $_POST.  Thanks again for the quick replies and taking the time to test the code, much appreciated.
