[Resolved] multiple checkboxes

[Butthead]

I goofed in my code. I guess I was tired and not thinking correctly.

I 'm trying to have multiple chckboxes on a page that when checked will print the values out on the next page (I'm still debugging, I'll make it pretty later).

The problem is that I set up the script so that it only prints the last one checked, and I'm trying to figure out how to slavage without rewriting that part of the script.

###index.php###
echo "<form action='/pdf.php' method='post'>";

    while(!$rs->EOF)
    {
            $invoice = $rs->fields["invoice"];
            print "
            <input type='hidden' value=$invoice name='invoice'>
            <input type='image' src='pdf.png'>
            <input type='checkbox' value='$invoice' name='checkbox'>
            <strong>Client Name</strong> ".$rs->fields["company_name"]." (<strong>invoice#</strong>: ".$rs->fields["invoice"]. " (<strong>Bill Date</strong>: ".$rs->fields["bill_date"].")<br>
            ";
            $rs->moveNext();
    }

echo "</form>";

###pdf.php###
<?
require_once('FPDF/fpdf.php');

if (isset($POST['invoice'])){
print "$invoice<br>";
if (isset($POST["checkbox"])){
print "$checkbox<br>";
}
}else{
print "it wasn't set";
}

###example###

let say the index page displayed

1
2
3
4

and I checked 1 and 2 and clicked the button

The following screen would display
4
2

Which makes sense because the first thing that pdf.php says is print $invoice which was overwritten each time through, and the second thing is print $checkbox which prints the last box checked because it too was overwritten each time through.

For some reason this code made sense when I wrote it but when it failed I could see why.

Any ideas on how to fix this?

my original suggestion from your previous thread on this code still stands: you need to return the form data as an array:

index.php

echo "<form action='/pdf.php' method='post'>"; 
while(!$rs->EOF) 
{ 
	$invoice = $rs->fields["invoice"]; 
	print " 
	<input type='image' src='pdf.png'> 
	<input type='checkbox' value='$invoice' name='checkbox[]'> 
	<strong>Client Name</strong> ".$rs->fields["company_name"]." (<strong>invoice#</strong>: ".$rs->fields["invoice"]. " (<strong>Bill Date</strong>: ".$rs->fields["bill_date"].")<br> 
	"; 
	$rs->moveNext(); 
} 
echo '
<input type="submit" name="submit" value="submit">
</form>
';

pdf.php

require_once('FPDF/fpdf.php'); 

if (isset($_POST['checkbox']))
{ 
	echo count($_POST['checkbox']) . ' invoices were checked:<br><br>';
	foreach ($_POST['checkbox'] as $value)
	{
		echo $value . '<br>';
	} 
}

else {echo 'no invoices were checked';}
