form action attribute

[boogiemacs]

Suppose I have a form in a file: form.php...
What are the differences, if any, to the following action attributes in a <form action=> tag?

1. action="" (open/close double quotes)
2. action="form.php"
3. action="<?=$_SERVER['PHP_SELF']?>"
4. action="<? echo $PHP_SELF ?>"

I keep getting inconsitencies when I click the Submit button.
Sometimes, I get DNS error when I use #1 above. Sometimes, it works fine on my web server.

Also, what's the diff between enclosing your script with <?php... and just plain <?...

<? is a shorthand way of doing <?php

try this one:
<form action="<?=$GLOBALS['PHP_SELF']?>" method=post>

There is no difference between variants 2, 3 and 4.

There also is no difference between <? and <?php.

Take a look at the generated html source code, so you will see, that the commands 2,3 and 4 produces the same output (html code).

If you want to use variant 1, I think it is better to omit the whole 'action=""' directive like

<form name="whatever">
</form>

Thanks, guys!
Now I can isolate these 2 possibilities for my crashing form scripts. I guess I am left now with my server as a problem. I keep getting "Cannot find server" errors especially with my SSL pages.

brøken is right... heineken is good...
