[RESOLVED] struggling with $_POST

marcnyc

Hello, I am having a hard time getting a value sent to via POST.

I have a PHP code which outputs this HTML:

Please select your preferred ADMIN AREA language:
	<!-- beginning of admin language selector drop down menu //-->
		<form action="/?p=menuedit" method="post">
			<script type="text/javascript">var url_full = "/?p=menuedit&l=en";</script>
			<img src="/images/flags_iso/24/us.png" style="position:relative;top:7px;" />
			<select name="l_admin" OnChange="this.form.submit();window.location.href=url_full;">
				<option value="en" selected>English</option>
				<option value="it">Italiano</option>
			</select>
		</form>
	<!-- end of admin language selector drop down menu //-->

I also tried using just <form action="" method="post"> or even just <form method="post">.

This form resides on the page /?p=menuedit (I am actually generating that part of the HTML with this PHP):

echo '<form action="/?'.$_SERVER['QUERY_STRING'].'" method="post">';

At the top of the page, for the sake of testing it, I put:

echo $_POST['l_admin'];

But every time I submit the form I get:

Notice: Undefined index: l_admin in /home2/memory/public_html/globals.inc.php on line 26

In other words, somehow it seems like my form is not submitting the post values... Can somebody help me figure out what I am doing wrong?

Thanks a lot

Hmm,

Can I ask why you are using window.location.href=url_full here ...
<select name="l_admin" OnChange="this.form.submit();window.location.href=url_full;">

... seems to me that after the form is submitted, the page is lost.

what do you mean by "the page is lost"?
The reason why I have that window.location.href is because I want the form to be submitted (and the language to change) instantly after somebody picks a new language from the drop down menu, as opposed to them having to click on a submit button...
am I doing it wrong?

marcnyc

does anyone else have an idea of what I could be doing wrong?

dagon

drop the "window.location ...

you only need the this.form.submit()

paulnaj

What I meant was this: the page that was receiving the form is not the one that is being viewed after window.location..., so the POST variable won't show up.

thanks, that helped a lot!
