Why are you suprised? When you press SUBMIT the same script is execute
(there is no selected item in it) due to action=\"$_SERV ER[PHP_SELF]\", so
where is pointing for previous selected item? No.

As you write the form into a variable and then output it, it makes it
complicated. I usually do:

<form action="<?php echo $_SERVER['PHP_SELF']; ?>" name="myform"
method="post">
<select name="obs_mnd">
<option value="Jan" <?php if(isset($obs_m nd) && $obs_mnd=="Jan" ) echo
"selected"; ?>>Januar</option>
....

I noticed that Message-ID: <407267ce$0$222 68$afc38c87@new s.easynet.ch>
from Markus Ernst contained the following:
[color=blue]
><form action="<?php echo $_SERVER['PHP_SELF']; ?>" name="myform"
>method="post ">
><select name="obs_mnd">
><option value="Jan" <?php if(isset($obs_m nd) && $obs_mnd=="Jan" ) echo
>"selected"; ?>>Januar</option>[/color]

I do a similar thing, but use a function. No easy way AFAIK (for some
value of 'easy')

Thank you. This is neat and I can understand it.
But my script should lead the user back to the form if it's not properly
filled out, while it's going to present the user with only "Thank you
....etc" if it _is_ properly filled out. Am I right to say that the form has
to be buildt as a variable to achieve that?

To interpolate a array element into a string you need to use curly brackets.

$form = "<form action\"{$_SERV ER['PHP_SELF']}\"> ... ";

Strictly speaking you don't NEED to, but you certainly SHOULD do.

No. For a conditional block of HTML you can do:

<? if($is_properly _filled_out) { ?>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" name="myform"
method="post">
<select name="obs_mnd">
....
<? }?>

or as I prefer it

<? if($is_properly _filled_out): ?>
<form action="<?=$_SE RVER['PHP_SELF']?>" name="myform"
method="post">
<select name="obs_mnd">
....
<? endif; ?>

For HTML that appears often, you can define it as a function

<? function PrintLoginForm( $name) { ?>
<? $name = htmlspecialchar s($name); ?>
<form>
<table><tr><t d>
<input name="name" value="<?=$name ?>"><br>
...
</table>
</form>
<? } ?>

Why, you are right! Though I would swear that's something that can't be
done. I guess you learn something new everyday.
