Trouble passing the values of dynamic textfield

[jackiw]

I have an order form, which gets the values from a sql database, and put each ID value in one table row as a name of a text field. Something like this:

<input name=bikini_01_size type=textfield>
<input name=bikini_01_color type=textfield>
<input name=bikini_01_qty type=textfield>

<input name=bikini_02_size type=textfield>
<input name=bikini_02_color type=textfield>
<input name=bikini_02_qty type=textfield>

and so on until the end of the table(from database). This works fine.

The question is, how can I submit the values of the textfield that the user entered to another php file (receipt.php), which does the order receipt, if I don't know how many I have? This is what I'm doing:

//receipt.php - Is supposed to get the values from a submited form

$dbq = mysql_query("Select * from bikinis where instock='yes'");
$numr = mysql_num_rows($dbq);

$email_message = "

Items Purchased:

";

$iv = 1;
while($iv <= $numr) {

$email_message .= "
Bikini $iv:
Size: $bikini".$iv."size
Color: $bikini".$iv."color
Qty: $bikini".$iv."qty
";

$iv++;
}

And what I get in the email is like:

Bikini 01:
Size: 01_size
Color: 01_color
Qty: 01_qty

Thanks a lot

Use hidden form fields. Have the first script output the hidden fields when it prints out the form for the receipt.php page.

Thanks for your help, but I think you misundertood.

What I'm trying to do is to get the values the user entered in the textfields and send to the next page, which will send the user an email with the purchase details.

I think instead of

$bikini_".$iv."_size 

what you're after is more like

${'bikini_'.$iv.'_size'}

But you'd get variables like $bikini_1_size, not $bikini_01_size; if that's a problem, mayhap [man]number_format[/man], [man]sprintf[/man] or [man]str_pad[/man] will fix that.

A further improvement would be, instead of

${'bikini_'.$iv.'_size'}

would be to use

$_POST['bikini_'.$iv.'_size']

.

Thanks Weedpacket, that really works!!!

Now, to get the total quantity of all the bikini_ID_qty text field, what should I do? Should I have an array?

[Weedpacket]

Probably (turning $POST['bikini_01_size'] into $bikini[1]['size'], say); but in this particular instance, since you're walking the array and looking at the quantities already, put a $total_qty=0 immediately before the loop and then within the loop have a line

$total_qty += $_POST['bikini_'.$iv.'qty'];

Depends on how elaborate you want to get.
