concat variable problem

[michaelowen]

hello!

i am submitting a credit card authorization form, and i am pulling my hair out over passing a combined variable.

here is what i think would be correct, but it's not working:

UMexpir = $month.$year;

but it does not give me the combined expiration date, so maybe it's a syntax issue:

---

<tr><td>Expiration Date: </td><td><select name="month">
<option value="">
<option value="01">01
<option value="02">02
<option value="03">03
<option value="04">04
<option value="05">05
<option value="06">06
<option value="07">07
<option value="08">08
<option value="09">09
<option value="10">10
<option value="11">11
<option value="12">12
</select>&nbsp;&nbsp;
<select name="year">
<option value="">
<option value="04">04
<option value="05">05
<option value="06">06
<option value="07">07
<option value="08">08
<option value="09">09
<option value="10">10
</select>
<br></td></tr>
<? php
$UMexpir = $month.$year;
?>

<input type="hidden" name="UMexpir" value="<?php echo $UMexpir ?>">

Anybody see what i'm doing wrong?

you have to combine the variable after the form submit, you can't create php variables on the fly via user interaction with a form. So when the user submits the form, have whatever page that handles it combine the two variables.

if it doesn't give you anything...you probably don't have register globals enabled, which, generally is a good thing (tm)...
so you use, depending if your form gets transmitted either via GET or POST:
$UMexpir=$GET['year'] . $GET['month'];
or
$UMexpir=$POST['year'] . $POST['month'];
otherwise post the output please
