help putting zero in front of single digits in select

Hello All,

Kind of new to PHP. I have an html form where a person inputs a date via
a drop down select. How do I make php put a zero in front of the numbers
1-9 ie. 01 02 03 when writing to the file? I have tried making the
value="01" etc. but this doesn't work. Below is a snippet of my form and
the code I am using to write to the file. I hope I have made myself
clear enough. Your help is greatly appreciated.
//form part
<select class="inform" name="logday">
<option value="1">1
<option value="2">2
<option value="3">3
<option value="4">4
<option value="5">5
<option value="6">6
<option value="7">7
<option value="8">8
<option value="9">9
<option value="10">10
etc,

//code part
fputs($out,"$_POST[logday] ");
Thanks,
Patrick

use something more like:
fputs($out,sprintf('%02d',intval($_POST['logday'])));

Unless you're doing something in your code to explicitly change the type
of $logday to numerical, there's no reason that zero-padding in the
VALUE attribute shouldn't work.

<?php
$x = '01';
echo $x;
?>

Outputs 01

<?php
$x = '01';
$x*= 1;
echo $x;
?>

Outputs 1

I figured it out.

$logday = $_POST[logday];

and then

fprintf($out,"%02d",$logday);

instead of the fputs, which gives me my leading zero.

Use this

<?

for ($i==1;$i<= 31;$i++)
{
if ($i < 10)
{
?>

<option value="<? echo $i; ?>"> 0<? echo $i; ?> </option>

<? } else { ?>
<option value="<? echo $i; ?>"> <? echo $i; ?> </option>

<?
}
}
?>

Enjoy it

use something more like:
fputs($out,sprintf('%02d',intval($_POST['logday'])));


or
fprintf($out, '%02d', $_POST['logday']);

Also, for kicks, the form part could be:

<select class="inform" name="logday">
<?php
foreach( range(1, 10) as $v ) {
printf("<option value="%d">%d</option>\n", $v);
}
?>
