Need Help with $HTTP_POST_VARS['referer'] ASAP

ATLien

First thanks in advanced.
Ok I am creating a site that requires a login. on this site people can leave comments for users. The thing is that users have to login to beable to post. If a user is not logged in when they go to comment to a user instead of the feild that assk for there name appearing. I have it set to show a link to the login screen. My problem is that at the login screen it has no value for $HTTP_POST_VARS['referer'] which is making it not send the person back to the comment area once signed in. How can I fix it so that when users click on the linkt o the login screen it will send the $HTTP_POST_VARS['referer'] varible with it.

If you want to pass a variable to another page using the POST method, then setup a form with a hidden field named referer. When they click the link for the next page, you can use javascript to submit the form.

describe this java script you are talking about
please

cgraz

<form name="form1" method="post" action="next_page.php">

<input type="hidden" name="referer" value="whatever">

<a onClick="javascript:form1.submit()">go to next page</a>

</form>

Then on next_page.php, you'll have access to the variable $HTTP_POST_VARS['referer'] (or for newer versions of PHP) $_POST['referer']

Note that on the <a onClick. . . part, javascript is two words. This is a change the forum makes when I submit my post, so make sure that you change java script to be one word, not two.

i am trying to use this <form> script to pass a variable from one page to the next... but i'd like to be able to put several links, instead of just one... I have one hidden field, and depending on what link is clicked, the value of that hidden field changes... is it possible to do? i'd appreciate ANY help!

I"m a little confused. Could you explain more?

But pretty much anything that changes before the form is submitted will need to be done w/javascript.

PHP is server-side
javascript is client-side

Or if you mean you want a hidden field, and depending which option they click (lets say add delete or modify), then on the next page in order to know what they want to do, you'll need to know which link they clicked. You do'nt even need a hidden input for this. What you'd do is pass a variable in your url:

Add: <a href=\"page.php?action=add\"><br>";
Modify: <a href=\"page.php?action=modify\"><br>";
Delete: <a href=\"page.php?action=delete\"><br>";

Then on page.php

if($action == "add") {
   echo "you want to add something";
} elseif ($action == "modify") {
   echo "you want to modify something";
} elseif ($action == "delete") {
   echo "you want to delete something";
}

here is what i'm trying to do: (thanks in advance, by the way)
i'm trying to integrate this with vBulletin

I want to click on this link:

<a href="t_index_login_test_b.php?videoid=1">View video 1</A>

... and pass that value of videoid as 1 to 'login_test.php' page. In turn, that page checks if the user is logged in or not... here is the statement on that page:

if ($bbuserinfo['userid']!=0) {

// User logged in fine

eval("\$welcometext = \"".gettemplate('index_welcometext')."\";");
eval("\$video_display = \"".gettemplate('video_display_YES')."\";");

} else {

//User isn't logged in

eval("\$welcometext = \"".gettemplate('index_logincode')."\";");
eval("\$video_display = \"".gettemplate('video_display_NO')."\";");

}

The problem is.... i need to be able to eventually pass the videoid variable to the template video_display_YES. (look in the code above).

SOOOO.... i'm stuck. hope this is enough info. let me know if it's not!

hmm I don't know. If you had an extension on the get template function,t hen you could use

gettemplate(param1, "templage.php?videoid=".$_GET["videoid"]);

You could always find where gettemplate function is defined, then modify it with an optional parameter for additional variables. I don't know how well that would work; just thinking outloud.
