Passing Variable to 2 pages

[Anon]

Hi,
I have a small problem, i have a link, which passes a vaiable, www.domain.com/page.php?lang=german this passes the variable $lang to a login page, so people get the login in german. Then they fill out their username & password, and press submit, however when they press submit, the next page doesn't have the variable. So its not in german. How do I get variable passed?
Cheers
Ben

define a hidden field in your form with the name german

<hidden name=german value=$german>

This will send the same variable to the next page...

Off course, I mean...

<hidden name=language value=$language>

which would hold german in the var language. What was I thinking ? 🙂

It should work very much like this forum. Where you click on the 'Coding Help' which passes the variable '?num=2'. Then when you fill in this message post, and press submit, the page refreshed, and the variable is still there. For some reason on mine, the variable disapears, when you submit.

there are three things that you can do:

1. you can place a cookie holding the language variable. this can be a problem since not everyone uses cookies.
2. you can add a dynamic tag to your form that will send the language variable to your script.
3. you can use sessions to store the variable. i think that session would be, by far, the easiest for this.

for more info on sessions go here:

Ah, ok

unless you redefine the variable and pass it, the variable will not automatically be passed to the next script. this is where sessions are a good thing.

Cookies and Sessions also come to mind. But the easiest wasy is to use a hidden variable.

It sounds like you are now using redirection and tacking on the variable, correct?

But your text box <INPUT TYPE="PASSWORD" NAME="the_pword" . . . > already will do this for you. When you get to the next form all you need is something like . . .

<INPUT TYPE = "hidden" NAME = "the_pword" VALUE = "<? echo $the_pword; ?>">

and the variable $the_pword is now available for use. You can continue passing on this hidden variable to as many pages in succession as you like.

Its the login script I got out of the code library. So its just 1 page/script. When you enter the username and password, and press submit, the page refreshes, and if the username & password is correct, it shows a menu. Its still actually the same page. I might try the <hidden name=lang value=$lang> see if that works.

just using the hidden-field in a form is by far the easiest way if you only have 2 pages. Off course, if you are dealing with a lot of pages, you are right.

[Anon]

Why not just take them to a new page? And on the way you can do all the PHP validation you want (with an intervening validation page). This way the hidden variables are guaranteed to work.

I use the scheme all the time and it works just fine. It also gets me around using Javascript for validation (in case they have JS turned off). And I can build custom error messages on the validation page. If everything is not right, I just send them back to page 1.

It's a little bit more work, but since it's all server side, it's pretty fool proof.

I'm having a similar problem passing variables.

I'm only passing variables to 2 pages also, everything's defined in hidden fields, once the data from the variables hits the first page, everything looks fine, it's the next page where I'm passing them to that only the first part of the text displays, anything that follows with a space is truncated. For example, I get "The"
when "The name of a book" is submitted.

Any suggestions?

thanks

Did you enclose the data of the hidden value in brackets ?

like this

<hidden name="yourname" value="blahbla blah blah">

if you forget the " ", only the first will be seen as value, the next will be seen as an other tag...

[Anon]

Thanks for your suggestion, I almost
had this worked out from what you suggested when I musst have changed something and now I cannot get this back where it should be, for example the submitting page looks like:

<form method="post" action="....../order.php">
<input type="hidden" name="artist" value="Artist Name">
<input type="hidden" name="title" value="This is the book title">
<input type="hidden" name="itemnumber" value="DYP-1105">
<input type="submit" name="Submit" value="Order Now">
</form>

This submits to order.php which has a code
snippet of:

<td width=295>
<input type="hidden" name="title" value="$title">
</td>

where the title should appear.

I've tried doing:
print("<input type=hidden name=title value=$title>\n");

with no luck either.

I thought I had this worked out, but must
have made some simple change I cannot
detect even though I've tried all the
combinations I can think of.

Your help is much appreciated, thanks!

tried

echo "<input hidden name=title value=\"$title\">"; ?

escape the " around $title so that the echo statement prints them...
