Remebering form variables

[Anon]

Every FAQ and documentation says that PHP automatically remembers a form field, so, if you create code like this,

<form>
<select name="test">
<option value="a" SELECTED>a
<option value="b">b
<option value="c">c
</select>
<?php echo $test;?>
</form>

The echo statement should return a. Right? Instead, on my server, it returns a undefined variable notice.

What am I doing wrong?

Thanks, guys.

that code will work if register_globals in ON in your php.ini. If it is not then you must do $POST['test'] or $GET['test'] depending on your form method.

try this way..
(i dont remember the predefined variable $PHP_SELF - form action - if it do not print the name of the current file, write it and remove that php block).

(you need to click in submit button labeled 'Go')

<form action="<?php echo $PHP_SELF; ?>">
<select name="test">
<option value="a" SELECTED>a
<option value="b">b
<option value="c">c
</select>
<?php echo $test; ?><br>
<?php echo $go_b; ?><br>
<input type="submit" name="go_b" value="Go">
</form>
