WP Super Cache plugin generates static html files from your dynamic WordPress blog. After a html file is generated your webserver will serve that file instead of processing the comparatively heavier and more expensive WordPress PHP scripts.

The static html files will be served to the vast majority of your users, but because a user's details are displayed in the comment form after they leave a comment those requests are handled by the legacy caching engine. Static files are served to:

1. Users who are not logged in.
2. Users who have not left a comment on your blog.
3. Or users who have not viewed a password protected post.

99% of your visitors will be served static html files. Those users who don't see the static files will still benefit because they will see different cached files that aren't quite as efficient but still better than uncached. This plugin will help your server cope with a front page appearance on digg.com or other social networking site.

If for some reason "supercaching" doesn't work on your server then don't worry. Caching will still be performed, but every request will require loading the PHP engine. In normal circumstances this isn't bad at all. Visitors to your site will notice no slowdown or difference. Supercache really comes into it's own if your server is underpowered, or you're experiencing heavy traffic. Super Cached html files will be served more quickly than PHP generated cached files but in every day use, the difference isn't noticeable.

The plugin serves cached files in 3 ways (ranked by speed):

1. Mod_Rewrite: The fastest method is by using Apache mod_rewrite (or whatever similar module your web server supports) to serve "supercached" static html files. This completely bypasses PHP and is extremely quick. If your server is hit by a deluge of traffic it is more likely to cope as the requests are "lighter". This does require the Apache mod_rewrite module (which is probably installed if you have custom permalinks) and a modification of your .htaccess file. Visits by anonymous or unknown users will be served this way.
2. PHP: Supercached static files can now be served by PHP. The plugin will serve a "supercached" file if it exists and it's almost as fast as the mod_rewrite method. It's easier to configure as the .htaccess file doesn't need to be changed. You still need a custom permalink. You can keep portions of your page dynamic in this caching mode. Your server may not cope as well with a really large amount of traffic. (You're gaming Digg aren't you? You'll need mod_rewrite, the rest of us are ok with PHP!)
3. Legacy caching: This is mainly used to cache pages for known users. These are logged in users, visitors who leave comments or those who should be shown custom per-user data. It's the most flexible caching method but also the slowest. As each page is different it's often better not to cache pages for these users at all and avoid legacy caching. Legacy caching will also cache visits by unknown users if this caching mode is selected. You can have dynamic parts to your page in this mode too.

If you're new to caching use PHP caching. It's easy to set up and very fast. Avoid legacy caching if you can.

In this article, we are going to discuss about How to rewrite the Drupal views output for custom theming and CSS. We were recently tasked with creating an events calendar that has a custom CCK field called "City". There's a drop down menu with a list of cities to assign the event to. So along with an event listing, you also see a city such as New York or Boston. The client wanted these cities to be color coded.

The issue was, how to assign the color to the city with CSS using Views. We tried a custom View theme template but this got us nowhere as there seemed to be no way to out put the names of fields.

Finally we hit upon it, there is an option in Views under Fields called "Rewrite the output of this field". When you click on a field to edit and select the checkbox for this option, you are presented with possible "Replacement patterns". In our case, we used the city location field as our CSS selector for the city location.



Here is our custom output rewrite code we used:

<div class="[field_event_location_value]">[field_event_location_value]</div>

The HTML output for the above is:

<div class="Boston">Boston</div>

We can now create a custom CSS class for Boston like this:

.page-events .Boston {
color:#2B0082;
}

Note that to utilize this properly you can only use fields that have come before the one you are currently working on so you may need to just rearrange the order or add a field but select "Exclude from display" just to get the data in to be available for use.

The possibilities for uses for Drupal Views Output Rewriting are endless and we are already using it for many different purposes for custom Views theming.

In this article, we are going to discuss about How to handle cookies in YII Php framework. A cookie is a small file that the server embeds on the user's computer and it is often used to identify a user. In plain PHP we can access using $_COOKIE global variable.

In Yii, cookie is an object of 'yii\web\Cookie'. 'yii\web\Request' and 'yii\web\Response' maintain a collection of cookies via the property named cookies.

Set Cookies

Using below code we can send the new cookie to the user.

$cookies = Yii::$app->response->cookies;
// add a new cookie to the response to be sent
$cookies->add(new \yii\web\Cookie([
    'name' => 'username',
    'value' => 'yiiuser',
]));

Get Cookies

We can get get the cookies from the yii app request.

$cookies = Yii::$app->request->cookies;
// get the cookie value 
$username = $cookies->getValue('username');
//return default value if the cookie is not available
$username = $cookies->getValue('username', 'default');
// Check the availability of the cookie
if ($cookies->has('username'))
echo $cookies->getValue('username');
 
Remove Cookies

To delete the cookie value, we can use the remove() function of yii.

$cookies = Yii::$app->response->cookies;
$cookies->remove('username');
unset($cookies['username']);

In this article, we are going to discuss about how to remove the index.php from the URL (enable search engine friendly SEF URL) in YII php framework. We can get the SEF url by removing the index.php from the URL. If you are using YII framework you are noticed that by default index.php will be included with your URL. In this article I am going to explain about How to remove the index.php from the YII framework site URL.

By removing the index.php from the URL we can get the site URL like below

http://domain.com/about

To acheive this, follow the below steps.

.htaccess

Please add the following lines in '.htaccess' file inside the 'web' directory of YII 2.0 application.

RewriteEngine on
# If a directory or a file exists, use it directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# Otherwise forward it to index.php
RewriteRule . index.php

Configuration of Web.php File

By default 'config/web.php' file does not have a option 'urlManager'. If we want to enable a pretty url, We have to add and configure the 'urlManager' in 'web.php' file.

To remove the 'index.php' from url, we have to the 'showScriptName' value as false.

To remove the 'r' route variable from url, set the 'enablePrettyUrl' value as true.

.................
'urlManager' => [
'class' => 'yii\web\UrlManager',
// Disable index.php
'showScriptName' => false,
// Disable r= routes
'enablePrettyUrl' => true,
'rules' => array(

),
],
.................
