I'm using following code for redirection in PHP
header("Location:restaurantsList.php?msg=Restaurant 100#we updated successfully");
In restaurantsList.php when i'm trying to get request parameters then getting following array.
Array ( [msg] => Restaurant 100 )
Param value is getting truncated after '#'.
If a pass any normal text in param (without #) then i'm getting whole string as it is.
Is there any solution to get string as it is, even if string will be containing #?
You should URL encode special characters in your query string so your URL would look like:
header("Location:restaurantsList.php?msg=Restaurant%20100%23we%20updated%20successfully");
The # symbol is used for anchor links and therefore must be encoded if used as "data" in the URL. You can use the urlencode PHP function for this. The # symbol would translate to %23
in url # behave as hash tag that called Fragment identifier
Javascript: window.location.hash; // this is return sting that start with # tag
You will need to encode url component in server side code to keep message
header("Location:restaurantsList.php?msg=".
urlencode("Restaurant 100#we updated successfully"));
OR
header("Location:restaurantsList.php?msg=Restaurant 100%23we updated successfully");
You need to urlencode the string after msg=:
header("Location:restaurantsList.php?msg=" . urlencode("Restaurant 100#we updated successfully");

I want to use the GET method to send a string to the receive page, but if the string includes '#', the receiver page can only get the sub string before the '#'.
As the following example:
test
When I click the 'test' link to open the 'test.php' page, which has the following code:
<?php
if(isset($_GET["q"])) {
echo $_GET["q"];
}
?>
It only display 'string1' on the page, '#string2' is missing.
So I want to know what happened to the string, and how to fix this problem.
Thank you for any help!
=======Update===========
With the help of #Eric Shaw and #JP Dupéré, I know how to fix this problem.
The simplest way is encoding the string before using the get method.
To encode the query string, you can:
use urlencode() in PHP, and urldecode() can decode the string.
use encodeURIComponent() in JavaScript, and decodeURIComponent() can decode the string.
Try
urlencode("string1#string2")
before calling GET.
The #foo is used to jump to an <a name="foo"/> tag on the page, rather than viewing the top of the page when the browser loads it.
The stuff after the # is processed by the browser and NOT sent to the server.
You can escape the # and the escaped version will be sent to the server, i.e.
test
will do what you want I think
This escaping is also a common technique to get the # passed along in the URL for redirectors.
I have been using URL decode on encoded URL variables from $_get.
The current problem I am facing is I have a URL encoded like this:
blah.php?url=http%3A%2F%2Fm.youtube.com%2F#/watch?feature=player_embedded&v=zd7c5tQCs1I&desktop_uri=%2Fwatch%3Fv%3Dzd7c5tQCs1I%26feature%3Dplayer_embedded
I'm not sure what kind of encoding this is, can someone help me? When I use just "urldecode" on this it just returns m.youtube.com
Edit: My problem is not that url decode isn't working, it works if I manually enter this encoded URL and use urldecode(), but when this encoded url is in the actual pages url and I use the _GET function then I try to decode it it stripes off everything after the "#" in the URL.
<?php print urldecode($_GET["url"]);?>
It returns
"http://m.youtube.com/"
instead of
"http://m.youtube.com/#/watch?feature=player_embedded&v=zd7c5tQCs1I&desktop_uri=/watch?v=zd7c5tQCs1I&feature=player_embedded"
I think the issue is that the pound sign is not encoded, if I refresh the page it strips away the pound sing and everything after it, so how do I get around this? Can I still retrieve the info from "GET" even though there is a pound sign? (#)
The problem is that the full link has multiple = signs, and browser cant determine, that the other = signs refer just to the url= parameter.
in your case, at first, you need to use function before link is given to url= parameter:
========================= 1) JAVASCRIPT ======================
<script type="text/javascript">
var mylink = encodeURIComponent('http://testest.com/link.php?name=sta&car=saab');
document.write("http://yoursite.com/url=" + mylink);
</script>
========================= 2)or PHP ===========================
<?php
$mylink = 'http://testest.com/link.php?name=sta&car=saab';
echo 'http://yoursite.com/url='.urlencode($mylink);
?>
so, your output (url parameter) will get like this
http://yoursite.com/url=http%3A%2F%2Ftest.com%2Flink.php%3Fname%3Dsta%
so, the url parameter will get the encoded url.
after that, your .php file needs to decode that "url" parameter-
<?php
$varr = $_GET['url'];
$varr = preg_replace("/%u([0-9a-f]{3,4})/i","&#x\\1;",urldecode($varr));
$varr = html_entity_decode($varr,null,'UTF-8');
echo $varr;
?>
that will give you the correct value
I read on php.net about urldecode function and they say that superglobal $_get is already decoded, ex: "The superglobals $_GET and $_REQUEST are already decoded. Using urldecode() on an element in $_GET or $_REQUEST could have unexpected and dangerous results."
It is encoded into ASCII format .
see http://www.w3schools.com/tags/ref_urlencode.asp
So here is the problem, the pound sign (#) (Hash) wasn't encoded... since I can't go back and re-encode it I have to use javascript (ex. alert(window.location.hash);) to send me the full URL after the hash then I append it to PHP's version of the URL, I THEN use a find and replace function in PHP to replace the "#" with "%23", then I use the urldecode method and it returns the full proper url decoded.
This encoding is called percent encoding or URL encoding. You can use urldecode for decoding it. (Example: http://phpfiddle.org/lite/code/0nj-198 )
I need to pass a url to a php page. the url may or may not contain special characters and encoded variables.
for example consider the ajax request.
var url = 'http://siteaddr.com/abc%20cdf%202012%20movies%20software/';
$.get('check_link.php',{url:url},function(){
//some function
});
the echo result of variable $_GET['url'] in the php page is http://siteaddr.com/abc cdf 2012 movies software/
the %20's are converted into spaces. I need to receive the url as it is.
tried encoding and decoding the url. but I didn't got the result as i need.
You're not supposed to define a variable with the name that will be used as a key.
Encoding the URL again, before sending it will make PHP decode the double encoded URL.
var link = 'http://siteaddr.com/abc%20cdf%202012%20movies%20software/';
$.get('check_link.php',{url: encodeURIComponent(link)}, function(){
//some function
});
// Double encoded URL: Note that % has become %25
// http%3A%2F%2Fsiteaddr.com%2Fabc%2520cdf%25202012%2520movies%2520software%2F

My variable with javascript looks like this:
var email = encodeURIComponent($('input[name=\'email\']').val())
email is clearly being encoded and is producing this when sent to server: email%2540yahoo.com
What function in PHP will decode this value properly?
I've tried using html_entity_decode
The correct url encoding for # is %40.
When a url, for example from an e-mail, with the encoded # character in it, is redirected using a rewrite rule, it will be rewritten as %2540 (the % is encoded as %25). If you keep rewriting / redirecting, you will replace % with %25 each time, ending up with %25252540 (or more 25, you get the picture).
For example clicking this:
http://example.org?email=info%40example.org
Will produce after a rewrite and redirect using a rewrite rule:
https://example.org?info%2540example.org
in the browser address bar, which does not correctly translate to info#example.org in php.
What function in PHP will decode this value properly?
You don't need to decode anything. $_GET["email"] and $_POST["email"] will work just fine. The encodeURIComponent function is used to properly url encode a url to avoid having invalid urls. If you have a valid url, PHP will successfully be able to read the parameters.
echo urldecode(urldecode('email%2540yahoo.com')); // email#yahoo.com
Try urldecode(<value_to_decode_here>);
I think I have the need to take a uri which has been decoded in PHP, and re-encode it.
Here is the situation:
JavaScript passes encoded uri as query string parameter to php script.
PHP script embeds uri as a hidden input value in an html document, responds with the document to a user agent.
JavaScript reads embedded uri and sets location of current document based on value of hidden input.
On Step 2, I am finding that the Uri is fully decoded after reading it in via $_GET. So when I embed the uri in the hidden input, it becomes un-encoded. So I would like to run a PHP script which re-encodes the Uri properly ex:
http://my.example.com/dog walk?is=very great
==>
http://my.example.com/dog%20walk?is=very%20great
Is there a pre-built php function for this or should I just write my own?
PLEASE NOTE: urlencode and urldecode are not the answer to get the desired input/output I have in the example above.
Thanks,
Macy
Are you looking for : http://fr.php.net/manual/en/function.urlencode.php ?
I don't know if will help you, but PHP have 3 useful functions:
$url = parse_url('put the url here');
parse_str( $url['query'], $query ); // generating an array by reference (yes, kinda weird)
echo $query; //in this line, you can encode or decode.
or, if you want to mount a query, you can use http_build_query(); that accepts values from an array, like:
$url = 'http://my.example.com/dog walk?';
$array = Array (
'is' => 'very_great',
);
$url_created = $url . http_build_query($array);
