[PHP] Passing a variable invisibly via a href?
Hi, i need to pass a variable by letting the user click on a link. Right now i do it like: page.php?variable=value However, i don´t want the variable, and it´s value to appear in the adress bar of the browser. And i don´t want people to be able to pass the same variable by reloading the destination page. Any pointers on how i can do this?

You could use a form and have a hidden vield that contains a value. The user would have to click the submit button for the variable/value to carry over though.

You could actually have javascript auto-submit the form if you didn't want the button like: script language=javascript document.form1.submit(); /script Adam Voigt [EMAIL PROTECTED] On Tue, 2 Apr 2002 09:08:18 -0600, Tyler Longren [EMAIL PROTECTED] wrote: You could use a form and have a hidden vield that contains a value.

You could use a form and have a hidden vield that contains a value. The user would have to click the submit button for the variable/value to carry over though. I thought about that. But i have two possible values (via two links) that could be passed and i can´t really get it together. Two forms? - Daniel -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

That might not be such a good idea then.

or use javascript href=javscript:form.submit() or if you really wanted you could encrypt the variable pass it via the url and then decrypt it on the next page! to avoid a reload put no-cache in the header. - Original Message - From: Daniel Alsén [EMAIL PROTECTED] To: PHP List [EMAIL PROTECTED] Sent: Tuesday, April 02, 2002 4:02 PM Subject: [PHP] Passing a variable invisibly via a href?

Yes, there is a way to do it without using any forms. I may be able to
help you better if you could show me the relevant code -- I'm not sure
if what I have in mind is really applicable to what you want to do.
It´s not really advanced:
session_start();
session_register('text_size');
if ($change == inc) {
$text_size++;
}
elseif ($change == dec) {
$text_size--;
}
I use the variable $change to set the text size in my stylesheet:
if (isset($text_size)) {echo $text_size;} else {echo 10; $text_size = 10;}
And i set the variable via a link:
a href=? echo $PHP_SELF; ??change=inc (or change=dec)
Now - i don´t want the variable to be visible. And i would prefer if the
variable didn´t get set every time someone hit reload.
Or am i attacking this changing-text-size-thingy the wrong way?

Hmm. I thought that I had a clever solution for you, but I don't. The
one that I came up with would probably be far more complex and inelegant
than you would ever want to use. If you were submitting your data to a
database or some kind of service, then it would work (I am thinking of
the PostToHost() function in the archives), but since you are trying to
set a session variable, you really need to refresh the page in the
process. This means that either using a form with POST data or the
querystring method that you mention above is really the best way to do
it.
If you used a form with POST data, you'd probably want to use radio
buttons or make a little listbox and a submit button, like:
form method=post action=?php echo $_SERVER['PHP_SELF']; ?
select name=change
option value=incIncrease Size/option
option value=decDecrease Size/option
/select
/form
This would keep your querystring/URL free of extra data like
page.php?change=inc.
