Menu
I am using a form and the 'get' method to offer users a return option to an unknown url that they came from within my site, as per the code below. I prefer this to just the browsers back button and it works without javascript.
The problem I am having is that some browsers (chrome, safari, there may be others) are adding a question mark to the end of the url they are referred back to. I don't want this for seo reasons.
My question is either:
1) Can I prevent the question mark within my php code somehow; or
2) Please could somebody show me how to redirect the url using htaccess, I potentially have urls that could end:-
.html?
.htm?
.php?
/?
Thanks in advance.
<?php
if (isset ($_SERVER['HTTP_REFERER']) ) {
$url = htmlspecialchars($_SERVER['HTTP_REFERER']);
echo '<br /><form action="' . $url . '" method="get">
<div id="submit"><input type="submit" value="Return to previous page" /></div>
</form>';
}
?>

indexOf method to get the index of the question mark. To remove a querystring from a url, call the slice() method on the url and get the characters from index 0 , up to the index of the question mark in the string. The slice method will return a new string that doesn't contain the querystring. Copied!
If you're using PHP for a server-side language, you can use something like... $nice_url = urlencode("http://your.old.url"); Other languages will have similar functions build in (or you can find one online). This will take care of your question mark (and other URL issues).
The question mark ("?", ASCII 3F hex) is used to delimit the boundary between the URI of a queryable object, and a set of words used to express a query on that object. When this form is used, the combined URI stands for the object which results from the query being applied to the original object.
The ? probably gets added because you're doing a GET request from a form.
Why not do something like:
<input type="button" onclick='document.location.href=<?php echo json_encode($url);?>'>;
use POST method instead of GET
