You'll need JS for that. Google "javascript alphabetize"

Or a server side language.

 

For example...

 

PHP:

 

<?php

$options = array('John', 'Eric', 'Thelma'); // and 97 others
sort($options);

?>

<?php foreach($options as $k=>$v){ ?>
<?php echo $v?>
<?php } ?>

 

Python:

 

options = ["John", "Eric", "Thelma"]
options.sort()
# Gives you a sorted list, then do your HTML thing as above

 

This could be done in javascript, but I wouldn't recommend it. Javascript might be switched off, and if you're injecting 100 elements into the DOM, that would be awfully slow. The best way to do it would be to put all 100 elements into an array, sort it, build the HTML in a string, then inject the string into the select list's innerHTML.

 

But really, server side is the way to go.

Use an associative array, and asort instead of sort:

 

<?php

$options = array('http://google.com'=>'Google', 'http://www.yahoo.com'=>'Yahoo', 'http://www.hotmail.com'=>'Hotmail'); 
asort($options);

?>

<?php foreach($options as $k=>$v){ ?>
<?php echo $v?>
<?php } ?>

[fazlionline]

<?php
$options = array('http://google.com'=>'Google', 'http://www.yahoo.com'=>'Yahoo', 'http://www.hotmail.com'=>'Hotmail');
asort($options);
?>

<?php foreach($options as $k=>$v){ ?>
<?php echo $v?>
<?php } ?>

Just change the extension of the file to .php, that should do the trick if you have PHP on your server.

<?php

asort($options);
?>

<?php foreach($options as $k=>$v){ ?>
<?php echo $v?>
<?php } ?>

What is it doing (or not doing) 'properly'?

 

Works fine for me. Google, then Hotmail, then Yahoo! in a drop-down select box.

 

Did you add a Submit button to the Form?

jhlaslip's solution (http://www.killersites.com/forums/post/5232/#p5232) should work perfectly, if you add it to the code that you already have.

[fazlionline]

Google

Hotmail

Yahoo
