[SOLVED] Making a field display zero

[kahodges]

I have a field used to display numerical data. I'm using it to display the amount of deductions used for payroll purposes. The field would require the numbers between 0 and 10. The problem I am running into is the field retaining and displaying zero once it's submitted through the form. All other numbers retain and display as they are supposed to. Example:

 

In the field, I type in number 1 and submit. I go back to the same form, the field displays 1. If I go to the same form, and type in number 0 (zero), hit submit, the form comes back blank. I need the form to retain and display 0 (zero) if that's the number entered.

 

Here is the code I am using:

<td colspan="2"><input name="deduction" type="text" id="deduction" <?php if (!empty($deduction)) echo "value=\"$deduction\""; ?>><div class="highlight" id="inf_deduction">

 

The database field is set up as MySQL 5.0 - field, varchar 12, latin1_swedish_ci, no attributes, null, default null, no extras.

 

Thanks in advance for your help.

OKay first the reason for the problem

0 = empty

 

the fix

<td colspan="2"><input name="deduction" type="text" id="deduction"
<?php 
if (!empty($deduction) && !is_numeric($deduction)) echo "value=\"$deduction\"";
?>
><div class="highlight" id="inf_deduction">

[sasa]

try

<td colspan="2"><input name="deduction" type="text" id="deduction" <?php if ($deduction !='') echo "value=\"$deduction\""; ?>><div class="highlight" id="inf_deduction">

Thank you both very much for the quick replies. I tried yours MAdTechie, but still ended up with the same results. However, using Sasa's solution did the trick.

 

Again,

Thanks.
