Use the javascript-console to catch errors like this (Tools / Web Development / JavaScript Console).

You will get the message "Error: document.forms. RedirectLogin has no properties".

That's because you have you javascript-code inline to execute as soon as the browser has reached that point. But no one can guarantee you (and this is what you are seeing) that the part of the page you're refering to is already properly initialized in the browser internals.

Put your code in the onload-Handler, this ensures everything is loaded and that the form is accessible:

<script type="text/javascript">
window.onload = function() {
document.forms["RedirectLo gin"].submit();
}
</script>

and remove the inline tag.

Re: form.submit and Netscape.

Netscape is traditionally slow in rendering forms (the payback for
multi-platform support). It could be that the form object is not initialized
by the moment of the function call, despite it comes after the form tag.

Use onLoad event instead.

<body onLoad='documen t.forms["RedirectLo gin"].submit()';">

The code is generated by a PHP script that "redirect" only on some cases.
It's quite a long work to change things. It's there an other way ?

How is it "long work" to include the onload event dynamically?

<?php
if (whateverYourCo nditionIs) {
print "<body onload=\"docume nt.forms['RedirectLogin'].submit();\">";
} else {
print "<body>";
}
?>

or

<?php
print "<body" .
(whateverYourCo nditionIs ? "
onload=\"docume nt.forms['RedirectLogin'].submit();\"" : "") .
" style=\"margin: 1em;\"" .
">";
?>

or

<body>

<?php
if (whateverYourCo nditionIs) {
print "<script type=\"text/javascript\">";
print "window.onl oad = function() {";
print "document.f orms['RedirectLogin'].submit();";
print "}";
print "</script>";
}
?>
</body>

I probably missed several hundred other ways of accomplishing what you want
using PHP. This is what PHP (or any other server-side technology) is for, to
_dynamically_ create content based on certain logic, conditions or data. The
fact that the content PHP is generating is client-side JavaScript is
irrelevant to PHP.

PHP can redirect to a new page without sending an intermediate
page to the client. Just send them the login page.

The problem is that I send user's datas trough POST vars, instead of GET, so
the only way I've found to redirect to some pages with vars in POST, is to
create a FORM with the vars and then submit it. Maybe there is a better way
?

Javascript can create dynamic <form> tag, as I send POST vars trough my
pages. I want to avoid to show various datas from my site, so for
redirecting, I've to create <form method="post"> and then submit it. If you
have a better way to redirect with post vars, please let me know.

Cheers.

A PHP group would be a better place to ask:

comp.lang.php
alt.comp.lang.p hp
