leading zeros problem

[webslinga]

Hey all,
I am creating a function that will take in the maximum value from a field in my database. I need to process that string and pass the id into a text field. I need to add leading zeros when appropriate (either 1 or 2 zeros). However, this does not work. I tried to do it with str_pad according to a previous thread in this forum but it did not work for me either. Here's a snippet of my code:

$nextOMSID = $omsids[0] + 1;

      if(strlen($nextOMSID) == 1)
        $nextOMSID = str_pad($nextOMSID, 2, '0', STR_PAD_LEFT);
      else if(strlen($nextOMSID) == 2)
        $nextOMSID = str_pad($nextOMSID, 1, '0', STR_PAD_LEFT);
      else
        $nextOMSID = str_pad($nextOMSID, 0, '0', STR_PAD_LEFT);

I also looked into sprintf and printf but they output the value and I just need to assign it to something else. Any feedback is welcome. Thanks.

could you do this instead:

$nextOMSID = $omsids[0] + 1;
if ($nextOMSID < 10):
 $nextOMSID = "00" . $nextOMSID;
elseif ($nextOMSID < 100):
 $nextOMSID = "0" . $nextOMSID;
endif;

I tried doing the following code and I can echo the result out and verify it's true. It's just that when I place it as a value in the textfield the leading zero gets stripped off. Any ideas?

      $nextOMSID = $omsids[0] + 1;
      $nextOMSID = sprintf("%03d", $nextOMSID);

using your code

$nextOMSID = 2;
$nextOMSID = sprintf("%03d", $nextOMSID);
echo "<form action=\"{$_SERVER['PHP_SELF']}\" method=\"post\">";
echo '<input name="test" type="text" value="'.$nextOMSID.'" />';
echo "<input type=\"submit\" value=\"submit\" name=\"submit\" />";
if (isset($_POST)):
 echo "<hr/><pre>";
 print_r($_POST);
endif;

i get the expected results.

Array
(
    [test] => 002
    [submit] => submit
)
