Thanks so much, Mark, Matt and John! I'll play with all those.

Much appreciated,

Here's the way I do it:

The following is an HTML code snippet with embedded PHP code for the
intelligence.

<select name="shipper>
     <option value="DHL" <? if ($shipped_via == "DHL") echo "selected";
?>>DHL
     <option value="FedEx" <? if ($shipped_via == "FedEx") echo "selected";
?>>FedEx
     <option value="UPS" <? if ($shipped_via == "UPS") echo "selected";
?>>UPS
</select>

Subject: [PHP] Prepopulating form fields afer an error

Hi,
I have a form and it does basic error checking after submission; when
the user omits required fields it kicks back the form with highlighted
errors telling them the error of their ways.

I've sussed out that by populating the value of the field with
$fieldvalue I can have that form field "populated" with the data the
user *did* enter for that field:

something like

<input type="text" name="email_address" value="<?php echo $email_address?>

That works great. But how can I do the same thing for drop down boxes,
when they select an option?

I tried the unwieldy,

<select name='blah'>
 <?php if (!empty(blah)) {
        echo "<option value='";
        echo "$blah";
        echo "'>"
        echo "$blah";
        echo "</option>\n";
    }
   ?>


And that, lo and behold, didn't work. Can anyone offer a suggestion?

Thanks in advance
JJ
