[SOLVED] Redisplaying a drop-down menu choice...

[fr00tloops]

I hope someone can help me out. I am fairly new to the PHP world, but getting the hang of it fairly quickly.

 

Right now I am working of this code below. The problem I am having is that I can't seem to figure out how to make it redisplay the drop-down menu choice (which is a state abbreviation) after it encounters an error. It always goes back to the default "  " as the choice.

 

I know I need to include an if-statement, I just don't know where.

 

Any and all help would be greatly appreciated.

it depends on how you have the dropdown coded.  Does it go through a loop displaying options from some query or something, or is it hardcoded?  If it is hardcoded, you need to make it looped by at the very least putting it into an array and looping through it.  That way in the loop that displays it, you would put something like this:

 

$selected = ($_POST['fieldname'])? "selected='selected'" : "";
echo "<option value='...' $selected> ... </option>";
