no idea whats going on here

I'm trying to generate a select box through php. Simple no problems there.

However, the problem comes when I try to dynamically add in the 'selected' attribute to one of the options.

My script is basically the following:

foreach($values as $key => $value) {
	if ($key == $checkVar) { $selected = ' SELECTED'; } else { $selected = ''; }
	$options .= '<option value="'.$key.'"'.$selected.'>'.$value.'</option>';
}

print '<select>'.$options.'</select>';

Goes through an array of values and if it matches the right one, addes the 'selected' attribute.

However, when I run this, it doesnt select the right option.

The thing that REALLY drives me nuts is that if I copy the direct source code that was generated from php into dreamweaver and preview it... it selects the option just fine.

I'm fresh out of ideas... anyone?

when you view the source of the generated page, is the html correct?

Also, is the $checkVar variable visible within the foreach loop? For example if the foreach loop is inside a function but $checkVar is declared outside that function, it will be invisible within the function unless you bring it in using global.

Yea, its visible.

The script 'works' just fine, the output is correct html, as far as I can tell. But for some reason it doesnt work freshly output from PHP. But if you copy the source and open that, it works fine... baffling.

Here is a trimmed copy of the source thats generated, you can see that the selected was printed:

<select id="state" name="state">
<option value="VA">Virginia</option>
<option value="WA">Washington</option>
<option value="WV">West Virginia</option>
<option value="WI" SELECTED>Wisconsin</option>
<option value="WY">Wyoming</option>
</select>

Try different browsers... maybe a setting is screwed up somewhere.

Can you show an example of the HTML source code when it does mess up?

Plus, how is $values created, can you show a print_r() of the $values
