Default list value does not display

tshaik

This is most likely pretty easy. If anyone has the answer, pleez let me know ASAP, before i explode...

I have a UPDATE form that updates values retrieved from my database.

The retrieved values are correct, but where no values are set in the database, none will obviously be displayed in my update form.

However, if no values are set in the dbase, the form defaults to the default list value. This it doesn't do. It sets all my options in the list to "selected". The last value in my list is then display in my drop-down box.

If anyone has the answer, now would be a great time to share it...

after fetching the rows from the db do a
<?
if ($field == "none") $field = "";
?>

Tried that already. It didn't work.

Thanks

can you one more time explain in more detail where you get stucked so i will try to help you, maybe u have a bit of code where the error appears

tshaik

function ReadIcons()
{
global $icons;

$handle = opendir('../images/outlook_icons');
while ( $file = readdir( $handle ) )
{
if ( $file != "." && $file != ".." )
{
$icons["../images/outlook_icons/$file"] = ereg_replace("....$", " ", $file);
}
}

} //end function ReadIcons()

function IconList( $selected )
{
global $icons;

reset( $icons );
//print_r( $icons );
while ( list( $file, $option ) = each( $icons ) )
{
$IconString .= "<option value=\"$file\"";
if ( $file == $selected )
{
$IconString .= " selected";
}

//error belor in else-statement!!
else if ( !$selected )
{
$file = "";
$file = "../images/outlook_icons/nodetails.gif";
$IconString .= " selected";
}
//end-error part

  $IconString .= ">$option</option>\n";
  $iconfound = "yes";

} //end-while
return $IconString;

closedir( $handle );

These are the two functions i'm using. I then just call the function (ReadIcons) later on, and set IconOptions = IconList( $SelectIcon) where IconOptions is called in my form and SelectIcon is an image.

The list box has an image next to it, that when u choose an option from the list, the image changes accordingly. Ic an't get the image and the default list value to display. I get a block with an 'x' in it = image and the first option in my list as my list value.

I might take long to reply to this again, as i need to leave pronto. Will reply tomorrow.

Thank you for your time and help
