• andare su >Gestione Hosting;
• configurazioni avanzate > Impostazioni;
• in Options cliccare su ‘Aggiungi’;
• dal menù a tendina scegliere ‘+SymLinksIfOwnerMatch’ e cliccare su avanti;
• viene aggiunto il valore ‘SymLinksIfOwnerMatch’ che ci permetterà di eseguire il rewrite.

Per quanto riguarda il pannello di controllo abbiamo finito.
Ora aprite il vostro .htaccess e aggiungete all’inizio del documento:

Options +FollowSymLinks
RewriteBase / 

Caricate tutto via FTP e testate.

First of all let’s add JQuery to our page:

   <script type="text/javascript" src="jquery.js"></script>

Launching code:

 $(document).ready(function(){
   // Your code here
 });

These are the methods I find more useful:

1. the .noConflict() method enables the use of multiple JS libraries (like Prototype)
2. the .addClass and .removeClass

    $(document).ready(function(){
        $('#your_id').addClass('your_class');
   
    });
   

3. the negation pseudo-class:

   $('#your_id li:not(.your_class)').addClass('your_class');

4. the :eq custom selector – selects the third item from a matched set of div selectors with a ‘my_class’ class

    $('div.my_class:eq(2)')

5. the :nth-child custom selector – matches elements which are the indexth child of their parent element

   $('tr:nth-child(index)').addClass('your_class');

6. the :odd and :even custom selectors:

    $('tr:odd').addClass('your_class');

7. the :contains() selector:

    $('td:contains(name)').addClass('your_class');

8. form selectors: :text, :checkbox, :radio, :button, :enabled, :checked, :selected

Shorthand events:

1. .click()
2. .toggle and .toggleClass()

    $(document).ready(function() {
      $('#my_id').click(function() {
        $('#my_id .button').toggleClass('my_class');
      });
    });
   

This in particular is very useful as it can perform actions in alternation.

3. .hover

   $(document).ready(function() {
     $('#my_id .button').hover(function() {
      $(this).addClass('my_class');
     }, function() {
       $(this).removeClass('my_class');
      });
    });
   

4. .css

   $(document).ready(function() {
       $('#my_id').css('border', '1px solid #000')
    });
   

5. .hide and .show

   $(document).ready(function() {
       $('p').hide();
    });
   

1. You need to have access to your webserver and upload to its root the .htaccess file. This is a simple file which tells the server to show a default page in case the one we are trying to access cannot be found. The file looks like this:

   ErrorDocument 404 http://www.yoursite.com/404.html
   

2. Upload to your webserver a file called 404.html previously edited; you may write custom sentences like ‘Sorry, but the page you are trying to reach does not exist’. If you like, you may add a custom search box: just browse to google webmaster tool in your google account and choose ‘optimize your 404 page’.

This tag (whose syntax is:

<link rel=”canonical” value=”http://example.com/page.html”/>

) helps webmaster to clean up duplicate urls on sites and is very useful when working with CMS such as wordpress for instance.

Check out the self-explanatory video or the page at googlewebmastercentral.

So this could be a good method to get a crossbrowser compatibility as well, a kind of ‘the progressive enhancement’ concept;
the browser has the flash player –> show the content with flash;
the browser has not the flash player –> show the alternative content;
the browser has not the flash player and is IE6 –> show the alternative content.

• Browse to code.google.com/p/swfobject/ and download the latest release;
• unzip the files to your swfobject folder;
• between the ‘head’ tags of your document just put the following:

  <script type="text/javascript" src="/folder/swfobject.js" language="javascript"></script>
  <script type="text/javascript" language="javascript">
          var flashvars = {};
          var params = {};
          params.wmode = "transparent";
  	params.menu = "hidden";
          var attributes = {};
          attributes.id = "your_id";
          swfobject.embedSWF("/swf/your.swf", "your_id", "your_width", "your_height", "9.0.0",
   "expressInstall.swf", flashvars, params, attributes);
  </script>
  

• between the ‘body’ tags of your document just put this:

  <div id="your_id">
  <img src="/images/alternative_image.png" alt="" /></div>

I always use an alternative image in case the user’s browser has not the flash plugin installed, so he may see an alternative content. Otherwise you can always put some text between the ‘div’ tags .
This is it, just test your page and see it at work; should you need more parameters just browse to the sfwobject documentation.

1. Quick variable retrieving (string):

   $page= $_GET["page"];
     if (!$page)   $page = "page name here";

2. Quick variable retrieving (number):

   $id= (int)$_GET["id"];
     if (!$id)   $id = 1;

3. A ‘for’ cycle:

   for($i=1950; $i<=2007; $i++) {
   echo "$i";
   }

4. A ‘switch’ statement:

   switch ($lang){
               case "" :
   	      echo "";
   	      break;
   	}

5. Antispam email:

   <?php
   function InsertMail($mail)
       {
       if ($mail=='') return '';
       $mail = str_replace(array('@',':','.'), array('&amp;#064;','&amp;#058;','&amp;#046;'), $mail);
       $mail = '<a href=mailto&amp;#058;'.$mail.'>'.$mail.'</a>';
       $len = strlen($mail);
       $i=0;
       while($i<$len)
           {
           $c = mt_rand(1,4);
           $par[] = (substr($mail, $i, $c));
           $i += $c;
           }
       $join = implode('"+ "', $par);
   
       return '<script type="text/javascript" language="javascript">
       <!--
       document.write("'.$join.'")
       //-->
       </script>';
       }
   echo InsertMail ('user@example.com');
   ?>
   

6. Replace accents in a query results

   function replace_accents($str) {
   $str = htmlentities($str, ENT_COMPAT, "UTF-8");
   $str = preg_replace('/&([a-zA-Z])(uml|acute|grave|circ|tilde);/','$1',$str);
   return html_entity_decode($str);}
