how to get previous page url when javascript is disabled? - html

How to get the previous URL when Javascript is disabled?
The page URL from where it is redirected?
The solution should be working fine in all browsers?

For a client side, imho there is only the JS solution.
var x = document.referrer;
But you can always use the PHP solution, if that is an option for you, the referer is part of the SERVER super array:
<?php echo $_SERVER['HTTP_REFERER']; ?>
Hope I could help.

I can only advise to look at $_SERVER["HTTP_REFERER"] in php.
But you should read about moments and specialties of using it.

Link that forwards the URL's parameters

There is a main Sales Page: site.com/sales-page
That page receives visitors from different traffic sources, and they are mentioned on its URL parameters, such as: site.com/sales-page?utm_source=fbads&utm_campaign=banner
That Sales Page has a link pointing to BUY NOW
How do I pass all URL parameters from the current window, such as "?utm_source=fbads&utm_campaign=banner" automatically to the next page via the BUY NOW button?
I need this so the Checkout page will know where the traffic came from, based on that forwarded parameter.
PS: I want to pass all parameters available in the URL, not just pre-defined ones.
PPS: Solution must work on most browsers and on static pages, better to not use cookies/php.
Thanks a lot.
There is no way to achieve this using HTML. You have to use a programming language.
For example:
<?php
$url = "http://example.com/foo/?" . $_SERVER['QUERY_STRING'];
?>
link
If you don't want to use PHP, then other programming languages are available.
There is no way to do it with just html. Best solution is serverside code. Fallback is to use JavaScript, but this will not work if JavaScript is disabled. You can read the search from the url and add it to your link.
<a id="buyNow" href="http://www.example.com">Buy</a>
<script>
(function () {
var lnk = document.getElementById("buyNow");
lnk.href = lnk.href + window.location.search;
}())
</script>
This assumes there is no querystring already on the link. If there is, you need to replace the ? in the search with a &

How to create a Random number or string in HTML without javascript or jquery

I want to generate a random number or string in HTML so that i add this to HTTP URL inside the HTML page to make it different each time page loads.
That's impossible. HTML is a markup language, and cannot be used for defining logic.
You should use server side scripting language for that.
HTML does not provide random number generation without using javascript OR jQuery.
if you want to avoid cache problem insuring user has a different url each time he loads the page, you can do something like :
<body onLoad="location.hash = Math.floor((Math.random() * 100) + 1);">
I don't think that works, because HTML is a static language.
Something that uses php help? example :
<?php
$url ='https://linkexample/ws/'+ rand(1,100); + '.com';
echo $url;
?>

how to post a value to a php page in a facebook app?

I am a noob facebook app developer and I would be very grateful for a little hand-holding getting started by professionals. I created a very simple app. It's only one file (index.php) and it has an html form that posts a value back to index.php to display. It worked before I added a "share to wall" request to the authentication. Now (I guess) there is a redirection before realoading the index.php, so it gets no $_POST value and it doesn't display the entered value. I would be very grateful if somebody would actually check out my app and its code and tell me how to fix it. (I think it's important to mention that it requests permission to post to the user's wall, but actually it doesn't post anything to the wall. I want to add that functionality later.) Here is the app:
https://apps.facebook.com/webszebb/
And here is the code (screenshot):
http://webszebb.hu/indexphp.png
Thanks.
For the sake of simplicity I'd suggest doing something like:
<html header stuff>
<?php
...snip...
if ($_REQUEST['do'] == 'whatever the action is, i.e: action="?foo" would be foo here') {
print('Your previous number was ' . $_POST['my_number']);
} else {
print('form');
}
?>
But to answer your question I'm assuming the $fb->api('/me') probably redirects you.

how do redirect values to other page without click event in html. Below code is fine IE. But Not in Mozila

I have implemented paypal in my web page. Process is 'given inputs are redirect to other page(2 nd page) which have to get that input and redirect to paypal page(third page). Here we submit data on first page. value pass to second page(in this page user interaction not allowed) after pass to third page.It works fine in IE . But Not In Mozila.Send any Solution.
Code sample(second page):
<%string product = Request.QueryString["productName"].ToString();%>
<% string amount = Request.QueryString["price"].ToString(); %>
">
">
document.all.frmpaypal.submit();
Fine in IE, Not In Mozila
document.getElementById("frmpaypal").submit();
document.all is an IE-only non-standard extension. You can use:
document.getElementById("frmpaypal").submit();
Which will work on both browsers. Better yet, use something like jQuery:
$("#frmpaypal").submit();
(This simple example doesn't really show you the power of jQuery, but you'll love it once you find out everything it can do!)
document.all is non-standard. Add an ID and use document.getElementById.
Have you checked into the possibility of sending values via GET instead of POST in the FORM's action attribute?
