      try:
      [php]
      echo $_GET['variableName'];
      echo $GLOBALS['QUERY_STRING']; //WHOLE THING
      [/PHP]

          Hi mcphearson. Welcome to TSDN!

          You can add variables, via the GET protocol, to the URL and fetch them in your code.

          If you want to pass a value for user ID, you might have an URL that looks like this:
          Code:
          www.example.com/page.php?userID=1
          Then you could fetch this variable via the $_GET super-global in your PHP code:
          [code=php]
          echo "User ID: ". $_GET['userID'];
          [/code]
          You can have more than one variable, just separate them with a & sign:
          Code:
          www.example.com/page.php?userID=1&userName=yourName
          P.S.
          I've edited the thread's title. Please take a look at our Posting Guidelines for tips on how to create good thread titles.

              thanks very much for your help

              although im still confused

              im not that great with php

              how would i include that code in to my site

              would i put that code in the link that i want to change

              for example

              <a href="http://www.domain.com/echo "User ID: ". $_GET['userID'];">

              so will the link change from the / onwards.. to the query in the Url??


              thanks in

              Ps im using dreamweaver if that makes any difference

                  no llike that :/
                  you have two choices
                  [php]
                  <html>
                  <body>
                  <a href="<?php echo "$PHP_SELF?user ID=$_GET['userID']"; ?>" >link</a>
                  </body>
                  </html>
                  [/php]
                  or you can echo everything :-)
                  [php]
                  <?php
                  echo "<html>
                  <body>
                  <a href='$PHP_SELF ?userID=$_GET['userID']'>link</a>
                  </body>
                  </html>
                  ";
                  [/php]
                  regards

                          I don't know which example you picked but I fixed both of them so you can use either one.

                              One can use $_GET or $_REQUEST method to pass a variable and the suggestions given by our forum friends are very correct. But, I insist to store the variable in a session variable and make the session alive until you are done with your job. Once your job is done, you can unset the session variable. You cannot send data through URL, which you wanted to be encrypted, since, data sent are visible in the address bar. I reckon this piece of information will help you.

                                  I think you're all missing his questions.

                                  He asked how to change

                                  [code=php]
                                  www.example.com ?username
                                  [/code]
                                  to
                                  [code=php]
                                  www.example.com/username
                                  [/code]

                                  I have an inkling he's likely to be talking about virtual hosting, is it? You know how MySpace has www.myawfulspac e.com/usersprofile

                                  I believe this would be done through .htaccess, but i really have no idea.

                                  Also, i don't even know whether this is what he asked ¬_¬ It just seemed no one took into consideration the /qwerty he talked about.

                                  If anyone knows any good tutorials on virtual hosting(not sure if it is that) could you post them please?

                                  Thanks :)
