Can I read the hash portion of the URL on my server-side application PHP Ruby Python etc

Question

Assuming a URL of   www example com  val 1 part2   PHP can read the request variables val1 using the GET array   Is the hash value part2 also readable  Or is this only upto the browser and JavaScript

User · Answer

We can do it with another approach too  Like first of all get the hash value from js and call the ajax using that parameter and can do whatever we want

Another solution is to add a hidden input field to the php page    lt input type  hidden  id  myHiddenLocationHash  name  myHiddenLocationHash  value    gt    Using javascript jQuery you can set the value of this field on the page load or responding to an event         myHiddenLocationHash   val document location hash replace             In php on the server side you can read this value using the   POST collection    server location hash     POST  myHiddenLocationHash

The hash is never sent to the server  so no

User · Answer

It is retrievable from Javascript - as window location hash  From there you could send it to the server with Ajax for example  or encode it and put it into URLs which can then be passed through to the server-side

Simple test  accessing http   localhost 8000 hello foo bar this-is-not-sent-to-server  python -c  import SimpleHTTPServer SimpleHTTPServer test    Serving HTTP on 0 0 0 0 port 8000     localhost - -  02 Jun 2009 12 48 47  code 404  message File not found localhost - -  02 Jun 2009 12 48 47   GET  hello foo bar HTTP 1 1  404 -   The server receives the request without the  appendage - anything after the hash tag is simply an anchor lookup on the client   You can find the anchor name used within the URL via javascript using  as an example    lt script gt alert window location hash   lt  script gt    The parse url   function in PHP can work if you already have the needed URL string including the fragment  http   codepad org BDqjtXix     lt   echo parse url  http   foo bar fizzbuzz  PHP URL FRAGMENT     gt   Output  fizzbuzz   But I don t think PHP receives the fragment information because it s client-only

The main problem is that the browser won t even send a request with a fragment part  The fragment part is resolved right there in the browser  So it s reachable through JavaScript   Anyway  you could parse a URL into bits  including the fragment part  using parse url    but it s obviously not your case

I think the hash-value is only used client-side  so you can t get it with php   you could redirect it with javascript to php though

What about  Dynamically grab the  hash  lt script gt  var urlhash   window location hash    get the hash from url     txthash   urlhash replace  quot   quot    quot  quot      remove the         alert txthash    lt  script gt    lt  php  hash    quot  lt script gt document writeln txthash   lt  script gt  quot   echo  hash    gt   To make it more fluent  Full Example using just Javascript and PHP  lt script gt  var urlhash   window location hash     get the hash from url txthash   urlhash replace  quot   quot    quot  quot       remove the    function changehash a b      window location hash   b    add hash to url      alert b     alert to test    location reload      reload page to show the current hash    lt  script gt    lt  php  hash    quot  lt script gt document writeln txthash   lt  script gt  quot    gt    lt a onclick  quot changehash this   hash1   quot  style  quot text-decoration  underline cursor  pointer  quot   gt Change to  hash1 lt  a gt  lt br  gt   lt a onclick  quot changehash this   hash2   quot  style  quot text-decoration  underline cursor  pointer  quot  gt Change to  hash2 lt  a gt  lt br  gt     lt  php echo  quot This is the current hash   quot     hash    gt

The answer is no   The main purpose of the hash is to scroll to a certain part of the page where you have defined a bookmark  e g  Scroll to this Part when page loads   The browse will scroll such that this line is the first visible content in the page  depending on how much content follows below the line   Yes javascript can acces it  and then a simple ajax call will do the magic

Th part of an URI after the   is called  fragment  and is by definition only available processed on client side  see https   en wikipedia org wiki Fragment identifier    On the client side  this can be accessed using javaScript with window location hash

User · Answer

Yes you can   Use this method to prevent errors    lt script gt   query location hash  document cookie   anchor  query   lt  script gt    And of course in PHP  explode that puppy and get one of the values   split   explode        COOKIE  anchor     print r  split 1      to test it  use print r  this line will print the value after the anchortag
