IE7和IE8 - 他们为什么不记得选择框值？

Question

I have a super simple form, with a select drop down box. All browsers remember the selection, except IE8 and IE7 (IE9 works). I am doing a post. the doctype is HTML. What else do I need to add?

print_R($_POST) shows the values correctly in all browsers including IE9 - except IE 7 and IE8

<form method='POST' action='/someaction'>
    Timezone : 
    <select name='user_time_zone' id='user_time_zone'>
        <option value='UTC'>UTC/GMT</option>
        more options here
    </select>
    <input type='submit' value='Set' style='padding-left: 5px; height: 30px; margin-bottom: 10px;'>
</form>

I suspect your problem is not with your browser, but rather with your code. Using http://browserstack.com , I was able to fire up a quick vm of Windows XP and test both IE7 and IE8. Further, I tested IE10 on my local machine - all browsers showed the posted data as expected.

<?php

    if (count($_POST)) var_dump($_POST);

?>

<form method='post'>
    <label for="user_time_zome">Timezone:</label> 
    <select name='user_time_zone' id='user_time_zone'>
        <option value='foo'>Foo</option>
        <option value="bar">Bar</option>
    </select>
    <input type='submit' value='Set'>
</form>

Sample Output:

array
  'user_time_zone' => string 'foo' (length=3)
